This Underrated Nutrient May Help Lower Heart Disease Risk by 16%, New Study Suggests

Key Points

* A new study found that getting moderate amounts of selenium may help lower heart disease risk by 16%.

* Selenium is found in foods like seafood, whole grains, eggs, dairy and Brazil nuts, among others.

* Dietary selenium was also associated with lower heart attack and coronary heart disease risk.

Selenium is a vital mineral that plays a crucial role in maintaining overall health and well-being. Found in a variety of foods, from nuts to fish, it supports important bodily functions, including immune system performance and antioxidant defense.

Research has shown that the amount of selenium in your diet can impact your overall health in many ways. For instance, one study found that getting enough selenium could help lower the chances of developing kidney stones in older adults.1 Selenium has also been linked to a reduced risk of arthritis and rheumatoid arthritis, along with supporting stronger bones.23 There’s even evidence suggesting that selenium might support better brain function.

Since cardiovascular disease is the No. 1 cause of death worldwide, finding ways to support heart health is key.  That’s why researchers recently tried to determine if there is a link between selenium intake and the risk of CVD, and their results were published in Scientific Reports. Here’s what they found.

How Was This Study Conducted?

To assess the link between selenium intake and cardiovascular disease risk, researchers analyzed data from the National Health and Nutrition Examination Survey (NHANES), a large study conducted in the United States to understand the health and nutrition of the U.S. population. This data provided insights into selenium intake from diet as well as various heart and blood vessel-related conditions, such as cardiovascular disease, heart failure, coronary heart disease, hardening of arteries, heart attack, chest pain (or angina) and stroke. The analysis included more than 39,000 participants.

To better understand how much selenium people were getting from their diets, participants in the NHANES study took part in two food-recall interviews. Researchers used specialized tools to analyze this information and calculate how much selenium each person consumed from natural food sources, like fruits, vegetables and meats. Selenium from supplements or medications wasn’t included in these calculations, which allowed researchers to focus solely on selenium consumed through regular diets.

To identify heart-related health conditions, participants were asked questions during interviews, either directly or through a caregiver. These questions included whether a doctor had told them they had issues like heart failure, angina (chest pain), heart attack or stroke. If a participant answered “yes” to any of these questions, they were considered to have a history of cardiovascular disease. 

The study looked at several heart-related outcomes, such as coronary heart disease and stroke, as well as other related issues like congestive heart failure. The researchers also collected a wide range of other details about participants, including their age, gender, race, education level, income and their history of drinking alcohol. 

On average, the participants were about 47 years old, with a fairly even split of women and men. The participants were grouped into three categories based on how much selenium they consumed in their diets, and relevant data was analyzed. 

What Did the Study Find?

The researchers observed that participants who consumed moderate or high amounts of selenium experienced heart-health benefits. The researchers also discovered specific tipping points for how dietary selenium intake relates to heart and stroke health. They found that consuming about 135 micrograms of selenium per day marked a key point where its protective effect against cardiovascular diseases and atherosclerotic cardiovascular diseases began to shift. Similarly, for stroke prevention, the key point was around 100 mcg per day. Beyond those levels, the benefits of selenium diminished, highlighting the importance of balanced intake.

The participants’ average selenium intake was 115 mcg per day, which is more than the recommended daily allowance for most adults. Among all participants, about 9% had cardiovascular disease, but that percentage went down as selenium intake increased. People in the highest selenium-intake group had a lower chance of conditions like stroke, heart failure and heart attacks compared to those in the lowest-intake group. Even after considering factors like age, sex and race, higher selenium intake was still associated with reduced cardiovascular disease risk. 

When comparing the group with the lowest selenium intake to those with higher selenium intake, the data shows that people who consumed moderate amounts of selenium had a 16% lower risk of CVD in a fully adjusted model. This means that when factors like age, sex and race were taken into account, the moderate selenium group still showed a significantly lower risk. But for people in the group with the highest selenium intake, the protective effects were no longer significant. This suggests that while moderate selenium intake may help reduce cardiovascular disease risk, consuming the highest levels doesn’t necessarily offer additional benefits.

Additional data shows how selenium intake can impact various heart-related conditions. Moderate selenium intake, for example, resulted in a lower risk of

  • coronary heart disease, by 20%
  • congestive heart failure, by 30%
  • heart attacks, by 25%
  • angina, by 30%

Overall, these findings highlight the potential of selenium as a key nutrient in heart health. 

But this study has some important limitations. Because it only captures data at one point in time, the researchers couldn’t see how people’s eating habits change over the years. Diets can change as people age, and these changes could impact the link between selenium intake and heart disease risk, but this study couldn’t explore that.

Another limitation is that the researchers relied on participants to report whether they had heart disease, which means there’s a chance some people might not remember or share their medical history accurately. Lastly, because of the way the study was designed, we can’t say for sure if eating more or less selenium causes changes in the risk for heart disease; we can only see an association.

How Does This Apply to Real Life?

Based on these findings, incorporating selenium-rich foods into your diet could be a simple yet impactful way to support heart health. By including selenium foods in moderation, you may improve your overall selenium intake, which, as the study suggests, may be linked to a reduction in the risk of conditions like stroke, heart attack or other cardiovascular issues. However, balancing selenium consumption is key. Over-consumption might lead to diminishing benefits or potential health risks, so staying within recommended dietary guidelines is crucial.

The recommended daily intake of selenium varies depending on age, sex and specific health conditions. For most adults, the recommended dietary allowance is 55 mcg per day. The tolerable upper intake level of selenium for adults is 400 mcg per day.

There are plenty of delicious foods that are naturally rich in selenium, so adding them to your meals is simple. Here’s a list of great options to consider:

  • Brazil nuts (they’re packed with selenium!) 
  • Seafood like tuna, sardines and shrimp 
  • Organ meats, such as liver 
  • Eggs 
  • Whole grains, like brown rice and whole-wheat bread 
  • Sunflower seeds 
  • Mushrooms 
  • Spinach 
  • Poultry, like chicken and turkey 
  • Dairy products, like yogurt and milk 

The Bottom Line

A study published in Scientific Reports suggests that selenium intake may be linked to heart-health benefits. This article underscores the importance of balanced selenium intake, with research highlighting its potential to reduce the risks of various cardiovascular conditions—as long as you don’t overdo it. 

By incorporating selenium-rich foods into your diet, you can take proactive steps toward enhancing your well-being. But it’s essential to remember that moderation is key. Too much selenium may lead to adverse effects, so following dietary guidelines is crucial to maintaining a healthy balance.

It’s important to remember that while selenium alone isn’t a magic solution, it’s a vital piece of the puzzle in fostering a heart-healthy lifestyle. When combined with other positive lifestyle choices, such as regular physical activity and avoiding harmful habits like smoking, selenium may offer some benefits. Always consult with health care professionals to tailor your nutrition and wellness approach to suit your individual needs.

Top 10 Biotin Rich Foods

Biotin, also known as vitamin B7 or vitamin H, is a water-soluble B vitamin that plays a crucial role in converting food into energy. This essential nutrient supports healthy hair, skin, brain function, and liver health. Since your body doesn't store biotin, you need to consume it regularly through your diet. 
 
While biotin deficiency is rare, maintaining adequate levels is important for optimal health. Adults need about 30 micrograms daily, and the best way to meet this requirement is through nutrient-dense whole foods rather than supplements. 
 
Here are the top 10 biotin-rich foods to add to your shopping list: 
 
1. Chicken Liver
Biotin content: 138 mcg per 3-ounce serving (460% DV) 
 
Chicken liver tops the list as the ultimate biotin powerhouse, delivering nearly five times your daily biotin needs in a single serving. This organ meat provides more biotin than any other food source because the liver naturally stores the majority of the body's biotin reserves. Beyond its impressive biotin content, chicken liver is also rich in vitamin A, iron, folate, and high-quality protein. For those new to organ meats, chicken liver has a milder flavor than beef liver, making it an excellent starting point. It can be pan-fried with caramelized onions and herbs, chopped and incorporated into pâtés or terrines, or minced and mixed into ground meat for burgers and meatballs. When cooked properly, chicken liver becomes creamy and rich, adding depth to any dish. 
 
2. Beef Liver  
Biotin content: 31 mcg per 3-ounce serving (103% DV) 
Beef liver ranks second among biotin superstars, providing just over your complete daily requirement in a single serving. Like chicken liver, it's packed with this essential vitamin because the liver naturally stores most of the body's biotin. Beef liver also delivers exceptional amounts of vitamin A, iron, copper, and B vitamins, making it one of the most nutrient-dense foods available. 
 
While beef liver has a stronger, more robust flavor than chicken liver, proper preparation can make it delicious and approachable. Soaking it in milk for 30 minutes before cooking can help mellow the taste. Traditional preparations include liver and onions, where the sweetness of caramelized onions complements the rich, mineral flavor. It can also be ground and mixed with regular ground beef for added nutrition without overwhelming flavor, or chopped finely and added to pasta sauces for a nutrient boost. 
 
3. Whole Soybeans
biotin-rich foods
Biotin content: 19.3 mcg per 3/4-cup serving (64% DV) 
 
Soybeans lead the plant-based biotin sources, offering impressive levels along with complete protein, fiber, and isoflavones. These versatile legumes provide nearly two-thirds of your daily biotin needs while delivering all nine essential amino acids, making them a nutritional powerhouse for vegetarians and vegans. 
 
Fresh soybeans, known as edamame, can be boiled and eaten as a snack or appetizer, simply seasoned with salt. Dried soybeans require longer cooking but can be incorporated into stews, curries, and grain bowls. They can also be roasted for a crunchy snack or ground into flour for baking. Fermented soy products like tempeh and miso also retain significant biotin content while offering additional probiotics and umami flavor to dishes. 
 
4. Eggs 
Biotin content: 10 mcg per whole cooked egg (33% DV) 
 
Eggs, particularly the yolks, provide excellent biotin content along with high-quality protein, iron, phosphorus, and choline for brain health. A single egg delivers about one-third of your daily biotin needs, making it an accessible and affordable way to boost your intake. The biotin is concentrated in the yolk, so don't skip this nutrient-dense part of the egg. 
 
Always cook eggs thoroughly to improve biotin absorption and reduce the risk of foodborne illness. Raw egg whites contain avidin, a protein that binds to biotin and prevents its absorption. Cooking deactivates avidin, allowing your body to fully utilize the biotin. Eggs are incredibly versatile—scrambled with vegetables, hard-boiled for snacks, poached over salads, or baked into frittatas and quiches. For maximum nutrition, choose pasture-raised eggs when possible, as they tend to have higher nutrient content. 
 
5. Nutritional Yeast

biotin-rich foods
Biotin content: 9.8 mcg per 5-gram serving (28% DV) 
 
This inactive yeast adds a cheesy, nutty flavor to dishes while delivering substantial biotin content—nearly one-third of your daily needs in just one serving. Nutritional yeast is particularly popular in plant-based cooking as a dairy-free cheese alternative, but it's beneficial for anyone looking to boost their biotin intake naturally. 
 
The yellow flakes dissolve easily and can be sprinkled on popcorn, pasta, salads, or roasted vegetables for an instant umami boost. It's also excellent blended into sauces, dressings, and dips. Many people use it to make dairy-free "cheese" sauces for mac and cheese or to add depth to soups and stews. Beyond biotin, nutritional yeast is often fortified with B vitamins, including B12, making it especially valuable for vegetarians and vegans. 
 
6. Fresh Button Mushrooms 
 
Biotin content: 5.6 mcg per cup chopped (19% DV) 
 
Fresh mushrooms naturally develop high biotin content as protection against parasites and predators in the wild, and this natural defense system translates into significant nutritional benefits for humans. Beyond biotin, mushrooms provide selenium, potassium, and vitamin D when exposed to UV light, while being naturally low in calories and sodium. 
 
Button mushrooms are the most common variety and have a mild, earthy flavor that works well in countless dishes. They can be sliced and sautéed for pasta dishes, stuffed with herbs and breadcrumbs for elegant appetizers, or added raw to salads for a fresh crunch. Roasting mushrooms concentrates their flavor and creates a meaty texture that works well as a meat substitute. For maximum biotin retention, avoid overcooking, and consider adding them to dishes near the end of cooking time. 
 
7. Roasted Peanuts
biotin-rich foods
Biotin content: 5 mcg per 1-ounce serving (17% DV) Peanuts lead the nut category for biotin content while providing healthy monounsaturated fats, plant-based protein, and fiber. Despite their name, peanuts are actually legumes, not tree nuts, which explains their higher biotin content compared to true nuts. They're also rich in niacin, folate, and vitamin E, making them a nutritionally dense snack option. 
 
Roasting peanuts enhances their flavor and makes them more shelf-stable, but raw peanuts also provide biotin. They make excellent snacks on their own or can be incorporated into trail mixes with dried fruit and seeds. Peanuts add protein and crunch to stir-fries, can be ground into natural peanut butter for spreads and sauces, or crushed and used as a coating for chicken or fish. For those with peanut allergies, other legumes like soybeans and lentils can provide similar biotin benefits.


 
8. Salmon 
Biotin content: 5 mcg per 3-ounce serving (17% DV) 
 
This omega-3 rich fish provides quality protein, healthy fats, and essential minerals like magnesium, phosphorus, and potassium alongside its biotin content. Salmon's omega-3 fatty acids support heart and brain health, while its complete protein profile helps maintain muscle mass and supports cellular repair. 
 
Wild-caught salmon typically has a more robust flavor and higher nutrient density than farmed varieties. The fish can be prepared in countless ways—grilled with herbs, baked with lemon and vegetables, pan-seared with a crispy skin, or poached gently for a delicate texture. Cold-smoked salmon works beautifully in salads and on toast, while canned salmon provides convenience and affordability without sacrificing nutritional value. Aim for at least two servings of fatty fish per week to maximize both biotin intake and omega-3 benefits. 
 
 
9. Sunflower Seeds

Biotin content: 2.6 mcg per 1/4-cup serving (9% DV) 
These portable powerhouses offer biotin along with vitamin E, healthy fats, magnesium, and plant-based protein. Sunflower seeds are particularly rich in vitamin E, a powerful antioxidant that protects cells from oxidative damage, while their magnesium content supports bone health and muscle function. 
 
Raw sunflower seeds have a mild, nutty flavor and satisfying crunch that makes them perfect for snacking. They can be toasted in a dry pan to enhance their flavor or seasoned with spices for variety. Sunflower seeds work well sprinkled on salads, yogurt, or oatmeal, mixed into granola and trail mix, or incorporated into baked goods like muffins and bread. They can also be ground into sunflower seed butter as an alternative to peanut butter for those with nut allergies. 
 
10. Sweet Potatoes 
 
Biotin content: 2.4 mcg per 1/2-cup cooked serving (8% DV) 
 
Sweet potatoes round out the top 10 with their natural sweetness and impressive nutrient profile. Beyond biotin, they provide fiber, vitamin A in the form of beta-carotene, potassium, and antioxidants that support immune function and eye health. The orange color indicates high levels of carotenoids, which have anti-inflammatory properties. 
 
These versatile root vegetables can be prepared in numerous ways to suit different tastes and dietary preferences. Baking whole sweet potatoes brings out their natural sweetness, while roasting sliced sweet potatoes creates caramelized edges and a tender interior. They can be mashed as a healthier alternative to regular potatoes, spiralized into "noodles" for low-carb dishes, or cubed and added to soups and stews. Sweet potato fries offer a nutritious alternative to regular fries, and they can even be incorporated into baked goods like muffins and pancakes for added nutrition and natural sweetness. 
 
Getting the Most from Biotin-Rich Foods 
Incorporating these biotin powerhouses into your diet is easier than you might think. Start your day with eggs, snack on nuts and seeds, add mushrooms to your lunch salad, or enjoy salmon for dinner. The key is variety—rotating through different biotin sources ensures you're getting adequate amounts while enjoying diverse flavors and textures.
