Key Points

‧ Recent surveys show up to 40% of men are concerned about fertility.

‧ There are many individual things someone can do to improve their fertility health.

‧ Checking with a fertility specialist is recommended if problems are suspected.

With studies reporting a significant decline in sperm counts across the globe, fertility health has been a top-of-mind concern for many men in recent years. In fact, a recent survey of 1,000 men, ages 25-54, found that nearly 40% of men are currently concerned with their fertility health.

While some causes of male fertility are genetic or structural and require help from a fertility doctor, there are lifestyle considerations and changes you can factor into your everyday routine to improve your wellness and optimize reproductive health.

Here are some tips to help improve male fertility:

1. Maintain a healthy weight

Having a higher body mass index (BMI) may have a negative impact on sperm production. Research suggests that if your BMI is on the higher side, you might be at a greater risk of experiencing fertility issues and sometimes pregnancy outcomes are negatively impacted. So, it’s worth keeping an eye on your BMI and taking steps to maintain a healthy weight if you’re planning to start a family. Focus on eating well-balanced meals, exercise three to four days a week, and aim for a BMI between 21 to 26.

2. Eat a nutritious diet

Consume a diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fat and include foods high in antioxidants, such as berries, leafy greens, nuts and seeds, which can help protect sperm from damage. Certain vitamins and supplements can also affect sperm health. Taking a multivitamin can provide additional antioxidants such as zinc, selenium and vitamin C — all of which are used by the testes to support sperm production.

3. Avoid tobacco

Smoking tobacco can take a serious toll on your overall health and wellness, and this includes negatively impacting your fertility. A meta-analysis of 20 studies with 5,865 participants found that smoking tobacco reduces sperm count and motility (how the sperm move/swim). If you smoke and are trying to conceive, it is time to kick the habit. Here are some tips from the CDC on how to quit smoking.

4. Consume alcohol in moderation

Excessive alcohol consumption can lower sperm counts, lower testosterone, and can disrupt reproductive hormone balance. So, what amount of alcohol is considered okay? The results from studies are inconsistent and there is no one study that gives direction on how much alcohol you should drink before your fertility is negatively impacted. But generally, fertility specialists recommend consuming less than four to six glasses of wine (or the equivalent) a week.

5. Exercise regularly

Some studies show that getting regular physical activity can increase testosterone levels and better sperm quality. However, excessive exercise may have a negative impact, so strike a balance.

6. Limit heat exposure

Avoid prolonged exposure to high temperatures, such as hot tubs, saunas, or tight-fitting underwear, as they can raise scrotal temperature and affect sperm production.

7. Minimize exposure to toxins

Reduce exposure to environmental toxins and chemicals that can harm sperm, such as pesticides, heavy metals, and certain workplace chemicals. Use protective clothing and follow safety guidelines if you work in a potentially hazardous environment.

8. Get enough sleep

Sleep deprivation has been correlated with a number of health concerns, including male fertility problems. Sufficient rest (aim for seven to eight hours each night) promotes hormonal balance and overall well-being.

If you’re concerned about your fertility, it is best to consult a fertility specialist. They can provide a thorough evaluation and recommend appropriate treatments or interventions based on your specific situation.

The ability of a person to reproduce naturally is referred to as fertility. When a man’s chances of getting his female spouse pregnant are poor, this is known as male infertility. Usually, it depends on how good his sperm cells are. Infertility can sometimes be related to sexual function, and it can also occasionally be related to the quality of the semen.

Male fertility really depends on a healthy sperm count. Sperm count can be affected by a variety of elements, such as nutrition and way of life. You can increase sperm count and overall fertility by incorporating particular nutrients into your diet. We’ll look at some fundamental dos and don’ts that have been demonstrated to have an impact on sperm count below.

Dietary do’s & don’ts to boost fertility in men:

Do’s

  1. Eat a balanced diet that includes plenty of fruits, vegetables, whole grains, lean proteins, and healthy fats.
  2. You certainly already know that vitamin C can strengthen the immune system. According to some research, consuming antioxidants like vitamin C may increase fertility.
  3. Cut back on processed and fast food, as they contain high levels of unhealthy fats, sugars, and artificial additives that can negatively impact fertility.
  4. Increase your intake of antioxidants such as vitamin E, and selenium, as they can help protect sperm from damage.
  5. Fertility in both men and women can benefit from vitamin D. Another vitamin that might raise testosterone levels is this one. Men who were vitamin D deficient had a higher likelihood of having low testosterone levels, according to one observational study.
  6. Fenugreek is an appreciated herb for both cooking and medicine. Supplements containing fenugreek have been demonstrated to considerably raise testosterone levels.
  7. One of the foundational elements of male fertility is getting adequate zinc. Additionally, taking zinc supplements may prevent the lower testosterone levels linked to overdoing it on high-intensity exercise.
  8. Ashwagandha is a herb used for medical purposes which can be added to your diet. According to studies, ashwagandha may increase testosterone levels, hence enhancing male fertility.

Don’ts

  1. Avoid or limit foods that are high in saturated and trans fats, such as red meat, fried foods, and baked goods, as they can decrease sperm count and motility.
  2. Reduce intake of soy products. Soy is abundant in isoflavones which causes an oestrogenic effect that drops the levels of testosterone.
  3. Avoiding consuming predator fish such as tuna and swordfish. These fish are high in mercury which can negatively affect our reproductive health and lead to fertility issues.
  4. Reduce your caffeine intake, as high levels can negatively impact sperm quality.
  5. Avoid or limit alcohol intake, as excessive consumption can decrease testosterone levels and impair sperm production.
  6. Avoid smoking and exposure to secondhand smoke, as they can damage sperm DNA and decrease sperm count.
  7. Don’t skip meals, as it can negatively affect hormone levels and overall sperm health.
  8. Foods in cans and tins are lined with a substance called bisphenol (BPA). Since bisphenol mimics oestrogen in the human body, it can have consequences akin to too much soy.

Follow these dietary dos and don’ts to improve your fertility and increase your chances of conceiving.

 

Biohacking and Optimising Your Health During Covid-19

How to Optimise Your Health During Covid-19 With Biohacking

By Dr Jonathan Seah | 14 Mar 2022

Our Takeaways:

· Dietary biohacks can be used for more efficient recovery from illnesses like Covid-19.

· It is possible to potimize the health beyond functional levels with diet and supplementation.

· Plant based and ketogenic diets are considered optimal for dealing with Covid-19.

For most of the past two years since the start of the COVID-19 pandemic, we’d been relatively fortunate in Hong Kong compared to many other cities in the world, without full lockdowns, mass testings, and most importantly, significant numbers of severely sick and dying people.

Unfortunately, this has all changed these past two months, with almost 500,000 cases and 2,000 deaths[1]. While most of these have been amongst the unvaccinated, elderly or chronically ill, some younger people and even children have been affected. Even though most of my friends are already vaccinated, they wanted to know if there was anything else they could do to improve their chances if infected. So after a chat with some LifeClinic doctors, I’ve summarized some suggested biohacks below – all of which are backed by peer-reviewed scientific research (links to the research papers are at the end).

Before I begin, it might be useful to understand how my medical philosophy differs from that of regular doctors. Most “conventional” doctors were taught, like I was over 30 years ago, that there are essentially only two states of health – either you are sick, or you are not sick. “Functional” medicine doctors, however, who are conventional doctors with extra related training, believe that it is possible to achieve an even better, “optimal” level of health – essentially a super-powered state that will allow you to function better than the average person at both work and play (potentially more energy, better memory, better sex, look younger), and to possibly live longer.

While media attention has focused on Hollywood and Hong Kong movie stars and Silicon Valley billionaires who see functional medicine doctors reverse both their internal and external ageing with advanced treatments like intravenous NAD+, peptides, exosomes, or cytokines, I personally believe that much of the benefits of functional medicine – especially with regards to improving your body’s immune functions to potentially reduce the severity of a COVID-19 infection – can be achieved with relatively inexpensive micronutrients you can purchase yourself[2].

What causes severe Covid-19 disease and death

As we have now seen over the past 2 years, about 80 percent of people who get COVID-19 have no symptoms or only mild symptoms, 14 percent get severe symptoms like pneumonia, and 5 percent get critical symptoms like respiratory distress or multi-organ failure, and about 2 percent die[3]. The mechanism for these bad outcomes is still being investigated, but much of the research points to abnormal immune responses (culminating in what has come to be called a “cytokine storm”) and the presence of chronic inflammation. We believe this is probably why the outcomes are often worse for older people[4], (who typically have aged immune systems), and for those with some pre-existing illnesses that cause systemic inflammation (like diabetes, high blood pressure, and cardiovascular disease)[5].

So, the question then becomes – what are some simple things we do ourselves to reduce the chronic inflammation in our bodies, and to rejuvenate our immune systems?

The best Covid-19 diets: Plant-based and clean keto

An unhealthy diet could increase your risk factors for a severe COVID-19 infection[6]. Over the past year, there have been a few very large research studies that have demonstrated quite clearly that what you eat can affect how your body reacts to COVID-19.

One of the most important was a study conducted amongst almost 3,000 front-line health care workers (doctors and nurses) across 6 countries, which showed that those who followed a largely plant-based diet (mostly vegetables and plant proteins, and less red and processed meats and sweetened beverages and alcohol), had a 73 percent lower likelihood of developing moderate-to-severe COVID-19 infections[7]! This is possibly because a plant-based diet often has more micronutrients that are essential for the proper functioning of the body’s immune system, such as polyphenols, carotenoids, dietary fibre, vitamins A, C, E, and folate, and minerals like iron, potassium, and magnesium. Or because the virus itself is weakened in a nutrient-dense environment[8]! Also, in this same study, those who ate a plant-based diet together with fish had a 59 percent lower chance of moderate-to-severe COVID-19 infection. In this case, it is thought that the mechanism of action might be a reduction of chronic systemic inflammation. Fish is an important source of vitamin D and omega-3 fatty acids, which have anti-inflammatory effects on the body. (Diazepam online)

An even larger study, this time of almost 600,000 people, also showed that those who ate diets characterized by more healthy plant-based foods correlated with a 41 percent lower chance of severe COVID-19 infections[9].

Separately, there has also been a lot of interest in investigating if ketogenic diets could be beneficial in COVID-19 patients. One study conducted in Italy on 102 hospitalized patients showed that those fed with a low-calorie ketogenic diet had a lower admission to the ICU and a lower death rate than those fed on a low-calorie standard (Mediterranean) diet[10]. This could be because a ketogenic diet can better regulate glucose metabolism and reduce systemic inflammation, as the SARS-CoV-2 virus seems to grow more quickly in a high glucose environment[11] and maybe why many diabetics have a severe COVID-19 infection. Additionally, the ketone bodies generated when a body is in ketosis appear to not only serve as fuel but also to promote resistance to oxidative and inflammatory stress[12] which can contribute to severe symptoms. Lastly, over time, ketogenic diets can reduce obesity and hypertension, which could also help improve COVID-19 outcomes.

So what are the key takeaways from this section? To increase your chances of a good outcome in case of infection, try to have a mostly plant-based diet or a “clean” ketogenic diet – that is to say, one that uses mostly plant fats, and fewer animal fats which of course can themselves be very inflammatory.

Biohacking: Your micronutrient heroes

Dietary insufficiency of vitamins and minerals has been observed in high-risk COVID-19 patients, which may account for the increased risk of severe infections. It is also noted that much of the evidence surrounding supportive micronutrient use in COVID-19 utilize doses too high to come just from diet. This is why, given the simplicity, relatively low cost and low risk, supplementation during this period might make sense for many people. The doctors at LifeClinic usually make customized supplement recommendations based on the results of some specialized blood tests and track your micronutrient levels over time. This is because everyone’s biology and needs are different. However, since not everybody will have the opportunity to have this done, I am sharing with you what many functional doctors recommend, and what I take myself! By the way – several of these supplements can also increase sex drive and the ability to achieve orgasm, so think of this as an additional benefit if you are in quarantine with your significant other[13][14].

Vitamin D

Vitamin D is a fat-soluble vitamin, that is both ingested via foods, as well as made by our bodies in the presence of sunlight – another reason my family loves to go hiking! Vitamin D insufficiency could affect almost 50% of the population worldwide[15]. Essential for a healthy lining in our throats to protect against the initial viral entry into our bodies[16], vitamin D is also critical for a healthy immune system. The primary effects of vitamin D in COVID-19 infections are to reduce the viability of the virus and the excessive inflammatory response[17]. In a study conducted on 212 COVID-19 cases, the probability of having a mild disease was correlated to high levels of vitamin D, and, as the vitamin D levels decreased, the risk of severe disease increased. In fact, in COVID-19 hospitalizations with vitamin D deficiencies, treatment with vitamin D shortened the hospital stays and decreased the death rate by more than twice[18]! Yulia and I take 5,000 IU of D3, and we give our son a few drops of D3 liquid every day. You might need more if your levels are low[19].

Vitamin C

Vitamin C is a water-soluble vitamin that cannot be made by humans, which means that it is not well stored in our bodies and must be taken regularly through food or supplements. In addition to being necessary for the body’s outer protective layers (skin and mucosa) and being a powerful antioxidant, it also has critical roles in immunity, including proper white cell movement and antibody production. While most conventional family doctors believe that just 90-120 mg daily[20] of vitamin C is sufficient, I would recommend higher doses to potentially help improve infection recovery times[21], as has been seen with the common cold and even pneumonia[22]. There is even documentation of more than 10,000 mg a day of vitamin C given intravenously (IV) as part of a successful COVID-19 hospital treatment programme[23]. Given that, at home, we can only use oral Vitamin C, Yulia and I take about 1,000 to 2,000 mg a day, and we give our son about 200 mg.

Zinc

Zinc is a key trace mineral that has many potential health benefits against COVID-19 infections, via improving the immune response, minimizing the inflammation, preventing lung injury, and inhibiting viral growth through the interference of the viral genome transcription, protein translation, and attachment[24][25]. It has been shown that zinc supplementation can increase the number of T cells and NK (natural killer) cells in your body – important parts of the immune system, and conversely zinc deficiency can lower the number of white blood cells that fight infections[26]. Several studies are currently ongoing to further investigate the effects of zinc on COVID-19 symptoms and outcomes[27]. We take between 30-50mg of zinc a day.

Quercetin

Quercetin is a natural substance known as a polyphenol. Its main natural sources in food are vegetables like onions and broccoli; fruits like apples, berry crops, and grapes; and some herbs; tea; and wine. It is an antioxidant and anti-inflammatory, can affect human immune functions, and also has antiviral properties. In a recent randomized study with 152 COVID-19 patients, it was found that in those who received quercetin 500 mg twice a day as supportive therapy, there were statistically significant improvements in all the clinical outcomes measured (the length of hospitalization, the need for oxygen therapy, progression to intensive care units, and death). The results also confirmed the very high safety profile of quercetin and its possible anti-fatigue and pro-appetite properties[28]. Yulia and I are currently following this protocol – 500 mg twice a day.

Omega-3 Fish Oil

Omega-3 fish oils are polyunsaturated fatty acids and include both eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids, and are known to have immunity and anti-inflammatory, and antiviral properties, and may even improve oxygenation in COVID-19 patients[29]. In a double-blind, randomized clinical trial conducted on 128 critically ill COVID-19 patients, omega-3 supplementation improved the levels of several parameters of respiratory and renal function[30]. However, on the negative side, there is also a possibility that they can make cell membranes more susceptible to non-enzymatic oxidation, so it is best to not overdo it. Yulia and I take 1,000 mg a day.

Probiotics

Maintaining good gut health is critical for a strong immune system. Our gastrointestinal system has trillions of microorganisms that live in harmony with us (this is known as your “gut biome”). They not only protect against harmful pathogens like the virus causing COVID-19 but also are a major “training ground” for our immune system. With modern living characterized by too much stress, refined carbohydrates, pollutants, medications and antibiotics, this protective lining can be severely weakened. Probiotics strengthen this barrier and can activate various protective immune factors such as IgA antibodies, cytotoxic T-cells and antimicrobial proteins. Recently a research study done right here in Hong Kong showed that there was a distinct correlation between the amount of certain healthy gut bacteria and the level of COVID-19 antibodies that developed after vaccinations[31]. I would recommend including a decent probiotic in your supplementation regime.

Of course, if you suspect your micronutrient levels are very low and you want a quick boost to your immunity, it might not be a bad time to get a consult with a functional medicine doctor or practitioner to evaluate if you might benefit from IV micronutrient therapy. However, if you’ve already been vaccinated and don’t have any major chronic illnesses, the above diet and supplements, in combination with some physical activity, would probably be enough to sufficiently improve your and your family’s chances of having just mild or no symptoms if you were to get COVID-19 infection – which for most of us will inevitably happen at some point! There are a few other micronutrients that you could consider adding, for example, selenium, magnesium and liposomal glutathione, but they’re not as easy to obtain locally. In any case, the very fact that you’ve actually read through this article means that you’re probably already doing all the right things. The very best wishes from our family to yours during this challenging time in Hong Kong!

A Nutrition PhD’s Advice & Tips For Optimizing Longevity

Yes, You Have Control Over Your Healthspan: A Nutrition PhD’s Advice For Optimizing Longevity

This article is a repost which originally appeared on mbghealth

Edited for content. The opinions expressed in this article may not reflect the opinions of this site’s editors, staff or members.

Our Takeaways:

· Healthspan refers to the period of life where someone has good health.

· Healthspan is heavily influenced by diet.

· Supplements can also be used to increase healthspan.

Once upon a time, I had a pretty awkward and comical date in Santa Monica. I was new-ish to Los Angeles and decided to try out a dating site that was famous for its robust matching algorithms. However, on this particular evening on Pico Boulevard, their matching science was, well, not so robust.

I probably should have known something was awry when the handsome maitre d’ wished me “good luck” in a distinct, you’re-gonna-need-it kind of tone before taking me to the table where my date was already seated.

In lieu of a warm salutation, my date stood up, scanned me from toes to head (yes, in that particular order), and proclaimed with some audible disappointment, “You’re taller than your dating app profile said.” I replied, “It’s nice to meet you too” like any gracious Southern lady would, and proceeded to sit my tall self down. (I’m actually a not-so-tall 5-feet-6-inches, but as my dating profile clearly stated, “I like to wear heels,” so you know…do the math.)

The rest of that date could inspire a Saturday Night Live skit, but allow me to cut to the nutrition-relevant chase (since this article is about nutrition principles for a long and healthy life—I promise).

A nutrition Ph.D.’s long-range nutrition philosophy.

After asking my date the obligatory question about what he did for work, I kept the convo flowing by sharing that I was a dietitian and nutrition research scientist. As with lots of strangers, my occupation immediately inspired my date to share his personal foraging and dietary practices with no prompting at all.

Specifically, he shared that since he works best in the wee hours of the morning, he eats supper at around 2 a.m. Rotating between three particular fast food joints, he picks up the food earlier in the day and refrigerates it to enjoy later (you know, at 2 a.m.). To be clear, he does not work a night-shift job. He then went on to say with adamance that he did not like or consume fruits, vegetables, fish, or most “healthy stuff.” Why? His rationale: “Life is too short. I’ll worry about eating healthy later.”

While the daily video gaming and other hobbies he mentioned were never going to fit with my interests and use of time, his eating habits specifically were sounding alarm bells in my dietitian head. Given his nutrient-depleted diet, it took me everything not to convert our date into an emergency nutrition counseling session that at least covered vitamin C, omega-3s, and fiber for everyone’s sake. (OK, I’m 80% joking).

You see, our nutrition philosophies and game plans for the long term were categorically opposed. I threw a bright yellow mental penalty flag down on the dating field and called it quits (in my mind of course—after all, I needed to finish my salmon and vegetables first!).

And while a date might just be a date, its future potential certainly plays a role in deciding whether to prolong said dating journey. The longevity of our hypothetical relationship was doomed for a variety of dating site algorithm failures, but like any research-minded Ph.D. nutritionist might ruminate (OK, maybe just me): This man’s lack of actual longevity potential flashed before my eyes as his shocking nutrient-lacking lifestyle was revealed.

It was like he had zero dollars in his nutrition 401(k) account, and I’m sorry, but that just doesn’t add up to a lengthy partnership.

Healthspan is not fixed (it’s malleable!).

Whether you’re looking for a good nutrition life match or simply cooking dinner for yourself, do we actually know what constitutes longevity food? And do we have the luxury to worry about eating healthy later, as my date suggested? The science is quite clear on that: Nope. At least not if the goal of living on this earth is thriving (instead of just surviving).

Regardless of your life stage, now is always the time to prioritize nutrition and other healthy lifestyle practices (i.e., restful sleep, physical activity, healthy body composition, smoking cessation, moderate or scant alcohol consumption, etc.). But is starting earlier best? Absolutely.

And as it turns out, we even know that certain patterns of macronutrients, micronutrients, and phytonutrients (i.e., plant bioactives) and their timing of consumption are tied to longer healthspan.

It’s so important to note that healthspan is malleable! Like the ultimate alley-oop basketball move: Your genes might be the setup, but nutrition is definitely the follow-through. Suboptimal nutrition can be a weak-sauce layup that barely makes it into the net, while a nutrient-dense lifestyle is like a fabulously confident dunk with some impressive hang time.

Smart nutrition: the ultimate power play for longevity.

Beyond the obvious role of taking in enough nutrients every day (i.e., get serious about nutritional sufficiency, whether that means a truly comprehensive multi, effective vitamin D3 supplement, filling your omega-3 gap, or more), our body is nutrient-responsive.

That’s because nutrients are fabulously multifunctional. Aside from being delicious, nutrition has the ability to positively affect so many physiological pathways and outcomes. Here are just a few that come to mind:

‧ boots-on-the-ground antioxidant fighting power against oxidative stress via an array of antioxidant vitamins, minerals, and phytonutrients from plants (fruits, vegetables, herbs, and more)

‧ anti-inflammatory marine omega-3s for resolution of inflammatory pathways

‧ prebiotic fibers and probiotic microbes for robust gut health

‧ 24/7 cellular cleanup and rejuvenation activities like detoxification and autophagy (think glutathione, milk thistle, CoQ10, etc.)

‧ adaptogens and nootropics for mental resilience and cognitive performance

‧ normocaloric intake of plant-centric carbs, proteins, and fats within a defined intermittent fasting window (e.g., 12 hours each day) for healthy body composition and cardiometabolic health

‧ intricate interplay of food and nutritional bioactives with your genes and DNA via precision nutrition solutions (e.g., for MTHFR gene variants) and epigenetic mechanisms

Smart nutrition is like a strategic biohacking strategy you tap into daily to thrive for the long haul. A recent, comprehensive research review examined this fascinating area of longevity nutrition, so you’ll want to check out the highlights and key nutritional pillars that represent a literal investment in your future.

Longevity nutrition is core to mbg philosophy, too.

Of course, if you’ve read mindbodygreen content for any period of time, you’ll probably know the pragmatic power of nutrition for health and longevity. This is not just something we cover in a journalistic sense. Longevity nutrition is actually core to the mindbodygreen philosophy, our portfolio of products, and the way we live.

In fact, the suite of premium products in mbg’s longevity & vitality collection were created with your healthspan in mind. By taking longevity support to the next level, these bioavailable nutrients, botanicals, and bioactives transform your daily regimen for healthy aging.*

From the 30 trillion cells that make up the human body, to how we look and feel—the fact is the amounts, types, and timing of nutrients and phytonutrients we choose to consume are absolutely pivotal to our health today and tomorrow. Nutrition isn’t sitting on the sidelines. It’s a versatile quarterback calling the plays.

Whether that “play” is to keep your brain sharp as a tack, maintain strong muscles and bones, promote insulin sensitivity and blood glucose balance, elevate gut microbial abundance and diversity, bolster your resilience to stressors, ensure your immune defenses are game for inevitable challenges that will come, or nurture collagen production—ultimately, these are all longevity plays, individually and collectively. They all rely on smart nutrition rooted in science.

The takeaway.

Some matches simply aren’t meant to be. But thankfully, unlike dating sites and the unpredictable nature of some human relationships, the “algorithm” underlying longevity is less cryptic, and healthful nutrition is paramount.

 

Nutrigenomics Might Be the Future of How You Eat

Medically reviewed by Kim Chin, RD, Nutrition — Written by Sarah Garone on March 16, 2021

This article is a repost which originally appeared on Healthline

Edited for content

Our Takeaways:

· Nutrigenomics is a field where a combination of disciplines merge to potentially optimize nutrition for individuals

· In addition to dietary optimization, nutrigenomics may also lead to more knowledge on finding and preventing health problems.

· Care should be taken when employing nutrigenomics as this branch of science is in its early stages.

If there’s one thing the last several decades of nutrition research have proven, it’s that there’s no one-size-fits-all diet. While many factors are at play, one reason certain eating plans work for one person but not another may have to do with our genetics.

Nutrigenomics is a fascinating, up-and-coming field that uses genetic testing to determine the interplay between genes, nutrition, and health. This information is used to help pinpoint the ideal diet for each individual.

Here’s a look at what nutrigenomics is, what you can expect if you try it, and how it might shape the future of personalized nutrition.

What is nutrigenomics? 

“Nutrigenomics is the study of the relationship between genomics, nutrition, and health,” says geneticist Jan Lim, MS, of CRI Genetics. “The field includes both the study of how the whole body responds to micro- and macronutrients, as well as the relationship between single genes and single gene/food compound interactions.”

You may sometimes hear this field referred to as “nutrigenetics.”

Technically, nutrigenomics refers to how nutrients influence your body to express genes, while nutrigenetics refers to how your body responds to nutrients because of your existing genetic makeup. However, many people use the terms interchangeably.

History of nutrigenomics

Though the science of nutrition genetics is still in its infancy, the idea that our genes can determine our best diet isn’t as space-age as it might seem.

In fact, as far back as the early 20th century, British physician Archibald Garrod is credited with establishing a connection between nutrition, genetics, and phenotype.

The Human Genome Project of the 1990s, which mapped out human DNA, paved the way for the modern era of nutrigenomics. Since then, hundreds of studies have examined genes’ influence on the body’s response to diet, as well as the other way around.

Today, it’s not uncommon for practitioners like dietitians and doctors to use genetic testing to assess patients’ dietary needs and set customized health goals.

Benefits

Genetic testing as part of nutrition counseling might sound rather extreme. A genetic workup just to see if you should eat low carb or get more vitamin C?

However, as part of an integrative nutrition approach, nutrigenomics can shed light on issues a simple health history can’t. This includes everything from a predisposition to heart disease to why you’re not losing weight when you’ve tried everything.

“Genomic testing truly is useful for anyone wanting to be proactive about their health,” says dietitian and certified genomic medical clinician Andrea Chernus, MS, RD, CGMC. “Genomic testing can help to explain why situations exist for a patient, such as which style of eating might suit them best.”

By looking at your genetic makeup, a practitioner may be able to advise you on certain eating patterns that will or won’t work well for you. For example, gene variants might mean your body wouldn’t benefit from a vegan diet or wouldn’t adapt well to a keto diet due to genomic tendencies for fat metabolism.

A nutrigenomic test can even uncover your personal best sources of both macro- and micronutrients.

Perhaps your body is unable to optimally use omega-3 fatty acids from plant sources, or you have trouble converting sunshine into vitamin D. With this data, a trained practitioner can instruct you on which foods to eat or supplements to take to meet your needs.

Likewise, predispositions toward certain diseases may show up on a nutrigenomics test.

“We may be able to see gene variants that increase one’s risk for breast cancer due to the genes involved in estrogen metabolism, for example,” Chernus notes. Heart disease, diabetes, obesity, and mental health have all been linked to genetic expressions, and all have dietary prevention strategies.

Empowered with this information, you can make preventative choices to mitigate risk through diet.

What to expect

Interested in pursuing a genetic approach to nutrition, but not sure what to expect? Nutrition counseling using nutrigenomics is surprisingly painless.

“The experience should start with a detailed health questionnaire so the practitioner has a complete understanding of the patient’s health status, history, family history, and current and past lifestyles,” says Chernus. “The actual test involves an at-home cheek swab. It’s typical for a test to evaluate anywhere from 80 to 150 or more genes. It’s quite simple to do.”

In some cases, if your results raise additional questions, a blood test may follow.

Once your test results are back, your dietitian or other health professional will evaluate them and work with you to develop an action plan for eating.

Potential drawbacks of nutrigenomics

Although extensive research has been conducted on the connection between genetics, diet, and health, the science of nutrigenomics is still emerging. “Nutrigenomics is a relatively new field of research, so we still have a lot to learn,” says Lim.

This isn’t to say that genetics aren’t a helpful piece of the puzzle when it comes to nutrition counseling. Just recognize that nutrigenomics won’t solve every diet conundrum, and that genes are just one of many factors that influence health and ideal dietary choices.

“Genomic testing should not be the sole criteria used to make recommendations,” says Chernus. “We need to include lifestyle, health history, health status, personal preferences, cultural identity, willingness of the patient to change, and their own health goals in our work.”

The availability of direct-to-consumer genetic testing for diet purposes, while it may seem exciting and convenient, is another potential drawback.

“The main drawback [of these tests] is that they’re not interpreted by a skilled clinician,” Chernus says. “Skilled practitioners use a polygenic approach: how all of the genes are part of bigger systems in the body. They interpret how these systems work together in the totality of one’s health.”

To understand the relationship between your own genome and diet, it’s always best to consult with a health professional who specializes in nutrition genetics.

Takeaway

“Every body is different” isn’t just true of our shape or physical type. It’s true down to the genetic level. Although nutrigenomics is a relatively new field that’s still gaining mainstream acceptance, many nutrition experts believe it’s the future of dietary counseling.

As part of a comprehensive nutrition philosophy that looks at the whole person, nutrigenomics could help people overcome health obstacles other approaches can’t.

“The more personalized our approach, the better the outcome,” says Chernus.

Celery Benefits for Men: Fact or Fiction?

Does Celery Have Benefits for Men?

Written by Daniel Preiato, RD, CSCS on November 13, 2020 — Medically reviewed by Jillian Kubala, MS, RD

This article is a repost which originally appeared on Healthline

Edited for content

Consuming celery and its juice has become increasingly popular in recent years due to its purported health benefits, one of them being improved sexual health for men.

Despite the lofty claims of various media outlets, data on the specific health benefits of consuming celery remains limited.

Nevertheless, some may wonder whether consuming celery has benefits for men.

This article details the potential effects of eating celery on several markers of men’s sexual health.

Myths vs. science

Various myths are circulating regarding celery’s purported benefits. Here’s what science has to say about some of the most common ones.

Does celery increase androsterone levels?

Androsterone is a weak steroid metabolite of the sex hormone testosterone, which naturally occurs in both sexes, although to a greater extent in men than in women (1).

This hormone, in conjunction with others, contributes to male characteristics like body hair and is found in human sweat (1).

Several media sources claim that celery is packed with androsterone and thus can lead to increased testosterone levels and sex drive in men.

Although some studies show that celery contains androsterone, there’s no evidence that eating celery or drinking its juice increases androsterone levels or improves sex drive in men.

Could this veggie be considered an aphrodisiac?

Aphrodisiacs are foods or drugs that stimulate sexual desire.

Pheromones are chemical hormones that function outside of the body and play a role in various phenomena, one of which is sexual attraction.

Androsterone is considered a pheromone, as it’s found in small amounts in human sweat.

Some claim that celery can serve as an aphrodisiac due to its pheromonic properties when eaten, though little to no research has been conducted on this subject. Therefore, more data is needed to confirm this potential effect.

SummaryWhile several media sources claim that celery can boost androsterone levels and serve as an aphrodisiac, limited to no data supports this theory, and more research is necessary.

Other potential benefits

Though data on the specific effects of celery intake on male sexual health is limited, celery may provide some other potential benefits.

May promote fertility

Celery is high in vitamin C and phytonutrients, which are antioxidant plant compounds that have been shown to have anti-inflammatory properties.

While antioxidants can help reduce disease risk, they may also promote male sexual health.

More specifically, select human studies suggest that a high antioxidant intake can help improve sperm count and motility, both vital factors in male fertility.

One animal study observed an increase in sperm production when supplementing with celery leaf extract.

However, extracts are much more concentrated and don’t necessarily compare to eating celery or drinking its juice.

Moreover, additional human research is needed to determine the specific benefits of celery on male fertility.

May help lower blood pressure

Celery and its juice may also aid blood pressure control.

This is likely due to the naturally occurring nitrates found in celery, which can promote heart health and help lower blood pressure.

What’s more, high blood pressure has been repeatedly linked to erectile dysfunction in men.

That said, regularly consuming a wide variety of fruits and vegetables, including celery, may improve symptoms of erectile dysfunction, though more data is needed on this subject to establish its specific benefits.

Lastly, depending on the degree of high blood pressure, prescription drugs may also be required. As such, it’s best to consult your healthcare provider.

High in vitamin K

Celery is a rich source of vitamin K, with 1 cup (124 grams) providing around 30% of the daily requirement for men.

Vitamin K is an important nutrient for blood clotting and bone health.

While the bacteria in your gut produce some vitamin K, dietary sources are required to help meet the daily requirement, which is around 120 mcg for men.

Regularly eating celery is a great way to help maintain vitamin K levels, in turn promoting bone health and efficient blood clotting.

SummaryThough data on the effect of celery on men’s health is limited, it may provide a few potential benefits, including promoting fertility, regulating blood pressure, and providing a rich source of vitamin K.

The bottom line

Consuming celery and its juice is an emerging health trend that claims to offer various benefits related to men’s sexual health, though data is lacking.

While it may marginally contribute to fertility, as well as help regulate blood pressure, more data is needed to determine its specific effects on other factors surrounding male sexual health.

That said, including celery and its juice as a part of an overall balanced diet is an excellent way to improve your nutritional intake and reap the benefits of the antioxidants it provides.

 

Fish oil can boost sperm count and make men’s testicles BIGGER, study claims

Fish oil can boost sperm count and make men’s testicles BIGGER, study claims

  • Scientists in Denmark tested the sperm and testicles of young, healthy men
  • Supplement-takers had bigger testicles and ejaculated more sperm, on average
  • Research only observed the link and could not prove supplements caused this
  • Experts say omega-3 could be a part of general good health, which is beneficial

Fish oil supplements could make men’s testicles bigger and boost their sperm count, a study claims.

Men who took the pills, which contain omega-3 fatty acids, were found to have testicles 1.5ml larger and to ejaculate 0.64ml more sperm, on average.

The men, who had an average age of 18, were included as regular supplement-takers if they had consumed fish oil for at least 60 out of the past 90 days.

Larger testicles and more sperm creation is linked to higher testosterone levels and better fertility, although the study did not test how fertile the men were.

The experiment was described by scientists as ‘well-conducted’ and ‘insightful’ but it was clear that it did not prove fish oil makes men more fertile.

Fish oil supplements contain omega-3 fatty acids, which are believed to reduce the risks of heart disease and improve brain health.

Researchers from the University of Southern Denmark did their study using 1,679 young Danish men going through military fitness testing.

In Denmark military service is mandatory for all healthy men over the age of 18, so the men in the study were not yet soldiers.

Each of the men were screened for STIs, had physical exams, gave sperm samples and then answered questions about their diets and lifestyles.

If someone was considered a regular fish oil supplement user, the research found, they produced millions more sperm in an average ejaculation.

The researchers wrote in their paper: ‘Fish oil supplements were associated … with higher semen volume and total sperm count, and larger testicular size.’

Ninety-eight men in the study said they took fish oil supplements regularly, while another 95 took vitamin D or C supplements.

Men in the fish oil group were less likely to have fertility problems, which were judged against the World Health Organization’s low sperm count limit of 39 million sperm per ml of semen.

The scientists found that 12.4 per cent of the men who took fish oil supplements (12 out of 98) had sperm counts below the WHO’s measure.

This compared to 17.2 per cent (192 out of 1,125) men who took no supplements.

And the longer someone had been taking supplements for, the more sperm they were likely to produce.

The researchers added that, based on a model fit and healthy 19-year-old: ‘Total sperm count was 147 million for men with no supplement intake, 159 million for men with other supplement intake, 168 million for men with fish oil supplement intake on fewer than 60 days, and 184 million for men with fish oil supplement intake on 60 or more days.’

The study did not give exact measurements for men’s testicle volume or sperm volumes – they only compared the two groups.

And the scientists could not explain why – if it was true – the fish oil improved sperm quality.

It was also not clear whether increased sperm volume was caused by – or caused – the change in testicle size.

Scientists not involved with the research said the study had been well-conducted but it didn’t say how much fish oil the men took.

And nor did it reveal the men’s diets, which may have shown they were getting omega-3 from other sources such as fresh fish.

Professor Sheena Lewis, reproductive medicine expert at Queen’s University, Belfast, said: ‘This is a large well-designed study and the association between fish oil intake and improved semen quality is compelling.

‘However, the study focuses on healthy young men; mostly with sperm counts already in the fertile range.

‘There is no evidence from this study that infertile men with low sperm counts benefit from fish oil.’

Dr Frankie Phillips, of the British Dietetic Association, said missing information about the men’s diets did make the study’s results less convincing.

She added: ‘Antioxidants, including vitamin C, selenium and vitamin A, as well as zinc and omega-3 fats all have a role in the production of healthy sperm.

‘There is much focus on the diets of women who are trying to conceive, ensuring that they are in the best possible position to achieve a healthy pregnancy, but diet might also be a factor involved in men’s reproductive health.

‘Omega-3 is present in a both animal and plant derived foods, but oily fish stands out as an excellent source of long chain omega-3, and the UK population currently consume way below the recommended ‘at least one portion of oily fish per week’.

‘So including omega-3 is already part of current dietary recommendations – this study on its own can’t prove that upping omega-3 will itself improve testicular function.’

The research was published in the journal JAMA Network Open, by the American Medical Association.

Men Should Eat These 11 Foods Every Day

Men Should Eat These 11 Foods Every Day

BY Rhett Butler

This article is a repost which originally appeared on THE SOURCE

Edited for content

Superfoods! More than a trendy buzzword, you need to incorporate these healthy superfoods in your diet every day.

Men especially should curate their refrigerator and try to stick to a healthy diet. However, walking through the grocery store can be confusing and many do not know where to start.

The Source has lined up some healthy food picks for daily consumption. They are based on the very common health issues males face.

May we present these 11 top choices for superfoods men should eat every day of the week.

SPINACH

Spinach is a super source of folate, a known blood flow-booster. Folic acid plays a critical role in male sexual function and a deficiency in folic acid has been linked to erectile dysfunction.

Cooked spinach contains 66 percent of your daily folic acid requirement per cup, making it one of the most folate-rich foods around. Additionally, spinach contains a fair amount of magnesium, which also helps improve and stimulate blood flow and has been shown as a trusted Source to boost testosterone levels.

Spinach is also good for penile health. It is a good source of folic acid which may help prevent erectile dysfunction. It also contains magnesium which has been shown to boost testosterone.

ALMONDS

Almonds contain zinc, selenium, and vitamin E, which are vitamins and minerals that seem to be important for sexual health and reproduction. Selenium can help with infertility issues and, with vitamin E, may help heart health. Zinc is a mineral that helps produce men’s sex hormones and can boost libido.

Compared to all other nuts, almonds are the most packed with nutrients and beneficial components. Now all you need to do is to at about 8-10 almonds a day. You can either eat soaked almonds or crush it and add to your morning salad or garnish your dishes, it is beneficial in any way you use it.

YOGURT

Improved digestion. Yogurt contains probiotic bacteria, which are primarily known for their ability to promote digestive health.

According to the Harvard School of Public Health, several of the strains of probiotic bacteria found in yogurt may help prevent or treat digestive difficulties including indigestion, diarrhea, irritable bowel syndrome and Crohn’s disease. Yogurt’s probiotics can also promote regular bowel movements, better immune system functioning and improved vitamin, mineral and nutrient absorption.

According to LiveStrong, if the results of studies conducted on male mice are any indication, yogurt may also have sexual benefits for men. Science suggests that certain dairy products, including yogurt, can help obese men lose weight. Finally, yogurt, and especially Greek yogurt, is a rich source of high-quality, muscle-building protein.

TOMATOES

Tomatoes have been linked to lowering men’s risk of stroke, helping fight prostate cancer, and preserving brain power with age. Heating tomatoes significantly increases their levels of lycopene, the chemical that can up antioxidant levels.

Lycopene – a nutrient found in tomatoes – may boost sperm quality, a study has suggested. Healthy men who took the equivalent of two tablespoons of (concentrated) tomato puree a day as a supplement were found to have better quality sperm. Male infertility affects up to half of couples who cannot conceive.

POTATOES

Potatoes are an excellent source of potassium, a nutrient most people don’t consume enough of, which can help regulate your blood pressure. They’re a good source of vitamin C and vitamin B6, which aids your nervous and immune systems.

The potato’s fiber, potassium, vitamin C, and vitamin B6 content, coupled with its lack of cholesterol, all support heart health. Potatoes contain significant amounts of fiber. Fiber helps lower the total amount of cholesterol in the blood, thereby decreasing the risk of heart disease.

SARDINES

Sardines contain 20 grams of protein per three-ounce serving, and are one of the best sources of calcium and vitamin D, both of which are essential for bone and muscle health. They’re high in omega-3 fatty acids, which help fight inflammation and lower LDL (bad) cholesterol. They might have workout benefits to boot.

Sardines contain 20 grams of protein per three-ounce serving, and are one of the best sources of calcium and vitamin D, both of which are essential for bone and muscle health.

They’re high in omega-3 fatty acids, which help fight inflammation and lower LDL (bad) cholesterol. They might have workout benefits to boot. Researchers from Saint Louis University found that athletes who took an omega-3 supplement before and after arm curls felt less sore than those who’d had a placebo.

BLUEBERRIES

All berries are good for your health. They’re loaded with antioxidants, which help your arteries relax and may have anti-aging effects as well. But for men especially, blueberries are king. Blueberries have lots of vitamin K, which helps your blood clot, and plenty of vitamin C like most berries.

A daily bowl could protect against obesity, heart disease and diabetes. A bowl of wild blueberries a day could protect against a range of health problems including obesity, heart disease and diabetes. Berries are rich in polyphenols – antioxidants that protect cells in the heart and help lower blood pressure.

AVOCADOS

Avocado is rich in folic acid for increased energy production, along with healthy fats to improve mood and sense of well-being. The more avocado you consume, the more blood flow your body experiences ― which is useful when it comes to sexual performance and in turn will also help lower the risk of heart disease.

Avocados are a great source of vitamins C, E, K, and B-6, as well as riboflavin, niacin, folate, pantothenic acid, magnesium, and potassium. They also provide lutein, beta-carotene, and omega-3 fatty acids. Although most of the calories in an avocado come from fat, don’t shy away!

WHOLE GRAINS

Foods such as wheat, rice, oats, cornmeal, barley, quinoa or products made from these foods are considered grains. Grains are high in carbohydrates which provide energy to your brain and muscles. Not all grains are created equally in terms of nutritional benefits. The health benefits of a grain depend on the form of the grain you actually eat. There are two types of grains: whole grains and refined grains.

When you eat a whole grain, your body is getting nutrients found in all parts of the grain, as well as fiber. Whole grain foods include oatmeal, brown rice, quinoa, and whole wheat bread or pasta. Refined grains have been processed and are missing some nutrients. Refined grain foods include white bread, white rice, and many kinds of pasta. When you eat grains, try having whole grains as much as possible.

A GLASS OF RED WINE

A study from 2019 reports that males who drank alcohol had a slightly lower risk of lethal prostate cancer, and that red wine had links with a lower risk of progression to lethal disease. The authors say that these results mean moderate alcohol consumption is safe for people with prostate cancer.

The health benefits from wine are the same for men and women, but men can drink more given their generally larger body mass — one or two 4-ounce glasses of wine per day — while women should consume only one glass.

WATERMELON

Watermelon may be a natural Viagra, says a researcher. That’s because the popular summer fruit is richer than experts believed in an amino acid called citrulline, which relaxes and dilates blood vessels much like Viagra and other drugs meant to treat erectile dysfunction (ED).

Watermelon is a natural source of citrulline. Citrulline is an amino acid that may support better erections. Viagra works by increasing blood flow to the penis, allowing a man to more easily get an erection when he is aroused. Citrulline may do the same thing, although it works in a different way to Viagra.

Stay healthy this summer and everyday!
