The 10 Best Foods & Herbs for Heart Health
You already know the heart is an incredible organ. But dig a little deeper and you discover just how truly miraculous it is.
For example, a typical heart beats more than 100,000 times a day and pumps 1.5 gallons of blood each minute. It’s also largely responsible for getting all that blood — which delivers essential nutrients and oxygen to organs and tissues near and far — through more than 60,000 miles of blood vessels.
As strong as it is, though, your heart is also extremely sensitive to diet and lifestyle factors; treat it poorly, and it’s at high risk for problems. Just consider that heart disease is the leading cause of death for both men and women in the U.S., and about three-quarters of a million people will suffer a heart attack each year.
Luckily, many of the problems are wholly preventable. Regular physical activity, stress management and adequate sleep are all excellent ways to preserve cardiovascular health. But, as the old saying goes, the quickest way to a person’s heart is through their stomach. In other words, one of the absolute best ways to protect your ticker — and your health as a whole — is through what you eat and herbal supplements you can take.
A generally healthy and balanced diet is the first step, of course. “When it comes to the body, you can’t look at things in isolation — so anything that’s good for your body will be good for your heart, and vice versa,” says Dr. Bill Rawls, M.D., medical director of Vital Plan.
That said, there are certain eating patterns and certain foods, herbs, and other natural substances that hold potent powers for promoting heart health and protecting your cellular health. They do it by targeting several main factors that keep your heart and entire circulatory system strong and healthy and blood flowing optimally.
10 Foods, Nutrients, and Herbs for Heart Health
While there are many different factors involved in keeping your heart healthy and blood flowing well (such as blood viscosity, cholesterol levels, and oxidative stress), the good news is that there are even more foods, herbs, and natural ingredients that help support and protect cellular and heart functions. Here are some of the best.
1. All the Veggies
A diet that consists of 50% vegetables is as good as it gets for your heart, Dr. Rawls says. Veggies are loaded with antioxidants that help tamp down inflammation and oxidative stress, plus they’re high in fiber, which works to control cholesterol and keep the good bacteria in your gut microbiome flourishing and the bad bugs in check.
Eating more vegetables also means there’s less room on your plate for starchy grains and other carbs that your body will turn into fat, and that triggers increases in cholesterol. There’s also less room for the meat and saturated fats that make blood thick and sticky.
Studies are unequivocal on the benefits of eating produce: The more you follow a plant-based diet and the more produce you consume, the healthier your heart, and the lower your risk for cardiovascular disease, heart failure, and a whole host of other diseases.
Need some guidance on where to begin in the produce section? There are some veggies that are heart health all-stars. They include:
- Leafy and cruciferous greens: Spinach, kale, broccoli, and cabbage contain vitamin K and nitrates, both of which are known to be natural blood thinners. The veggies may also help control cholesterol by being able to bind to bile acid. A review in the journal Cardiovascular Disease, for example, found that consuming these veggies reduces the risk of heart disease by 16 percent.
- Garlic, onions and leeks: They belong to a group known as allium vegetables, which are high in organosulfur compounds. Specialized antioxidant phytochemicals, these compounds are anti-inflammatory and prevent the production of free radicals. They also help maintain healthy blood viscosity (how thick and sticky blood is) and increase the availability of nitric oxide, a natural chemical produced by the lining of blood vessels that helps them expand and may lower blood pressure. Research has shown that consuming allium veggies may lower your risk of a number of different heart problems. Garlic is also well known for its anti-microbial powers, which could help maintain balance among gut bacteria, Dr. Rawls says.
- Avocados: These cult classics are brimming with nutrients, fiber, and heart-healthy monounsaturated fat, which may help decrease blood viscosity, Dr. Rawls says. Consumption of avocados has also been shown to increase levels of “good” HDL cholesterol, according to a review in American Journal of Clinical Nutrition. HDL particles are the antithesis to LDL; they scavenge for damaging cholesterol in the blood so it can be recycled by the liver, Dr. Rawls explains.
- Olives and olive oil: They fill you up with lots of healthy monounsaturated fat, plus olives are a well-known anti-inflammatory food thanks to their antioxidant polyphenols. People who consumed the most extra virgin olive oil, for example, had an almost 40% reduction in cardiovascular disease risk, according to a study in BMC Medicine.
- Edamame and tofu: Packed with fiber, they also contain specialized protein with bioactive peptides known to help lower cholesterol. One analysis of 46 different studies concluded that consuming soy reduces total cholesterol as well as dangerous LDL. Soy is also rich in antioxidants and may help improve the function of blood vessel linings.
Like veggies, all types of fruit will help your heart by providing plenty of antioxidants and fiber while crowding out foods that do cardiovascular damage. But there’s something special about blueberries — namely specialized polyphenol antioxidants. Studies suggest consuming these richly colored berries helps improve endothelial function (the lining of blood vessels), arterial stiffness, and even blood pressure.
3. Omega-3 Fatty Acids
Whether you get them in fish like salmon and sardines, flaxseeds, or from krill oil or fish oil supplements, these polyunsaturated fats have a number of beneficial qualities. They’re anti-inflammatory and fight oxidative stress, Dr. Rawls says, plus research suggests they raise your good HDL cholesterol and may help improve your body’s cholesterol profile in other ways. Omega-3s also help improve blood viscosity, according to a report in the journal Open Heart, and they’re associated with lower risk for obesity, a major co-factor for heart problems.
Dr. Rawls’ preferred source of omega-3s is krill oil because its phospholipid structure lends itself to greater absorption and contains other powerhouse nutrients, including astaxanthin and choline. Plus, it’s less likely to accumulate mercury than many of many options.
4. “Better” Whole Grains
Grains aren’t totally banned from a heart-healthy menu; just be sure to consume them in moderation and make smart choices. That means ditching bread and other wheat-based, packaged foods and instead consuming small amounts of true whole grains like oats, barley, quinoa, and brown basmati rice, Dr. Rawls says.
The fiber in these grains helps keep blood sugar levels stable — e.g. they won’t flood your system with more glucose than it can burn or store — plus, it removes excess cholesterol from your system. In fact, one large-scale review published in the journal BMJ found that three servings of whole grains a day (half a cup of cooked quinoa, oatmeal, or brown rice is one serving) reduced the risk of coronary heart disease, cardiovascular disease, and stroke.
A great source of healthy fat as well as fiber, antioxidants, and other nutrients, nuts such as almonds and walnuts have repeatedly been shown to affect healthy changes on cholesterol, including increasing healthy HDL and lowering LDL, plus improving endothelial function. They also help lower blood viscosity, Dr. Rawls says.
Multiple studies have also found that those who eat nuts have lower risk of cardiovascular diseases. For example, one study in the journal Circulation Research reported that those with type 2-diabetes (a known risk factor for heart disease) who ate nuts had a lower risk of cardiovascular disease and mortality.
6. Hawthorn Leaf Extract
A member of the rose family, the hawthorn plant has been used for centuries for medicine, and its extract is often referred to as a “heart tonic” thanks to its myriad of benefits. “It causes mild dilation of coronary blood vessels, which helps increase and ease blood flow and lowers blood pressure,” Dr. Rawls says.
There are actually multiple compounds in the extract that exhibit properties that help improve blood viscosity, a study in the journal Food & Function found. “Hawthorn also increases integrity of blood vessels and the contractility of the heart — meaning it helps the heart beat better and reduces abnormal rhythms,” Dr. Rawls adds.
7. Antioxidant Herbs
Herbs are a great way to reap the heart-protecting rewards of antioxidants. Japanese knotweed, for example, contains high concentrations of an active form of resveratrol. A potent anti-inflammatory and antioxidant also found in grapes, it’s been shown to protect the heart and improve endothelial function. Pine bark extracts is another herb with antioxidant properties that may also improve blood viscosity, according to a review in the International Journal of Clinical Pharmacological Therapy.
Rutin and hesperidin are two others known for antioxidant and cardiovascular benefits. “These herbs do a lot of beneficial things in the body, but one of the most significant is how they help protect and promote the health of blood vessels,” Dr. Rawls says.
8. Adaptogen Herbs and Fungi
Reishi mushroom, cordyceps, ashwagandha, and rhodiola are all well-known adaptogens. “Adaptogens all have really nice heart effects, because they help the body adapt to stressors,” Dr. Rawls says. That includes both physical and mental stress, both of which can impact heart health. Rhodiola, for example, helps promote healthy oxygen delivery to the heart and other tissues, while ashwagandha helps manage stress and anxiety.
Used for thousands of years in Chinese and traditional medicine, this bitter extract that’s found in multiple different barks, roots and plants is best known for its gut-balancing properties. That alone may help promote a healthy heart, given the gut-heart connection, but now researchers are finding berberine may exert direct beneficial effects on the heart. A review in the journal Chronic Diseases and Translational Medicine, for example, reports that berberine extract may do everything from help regulate blood pressure and cholesterol to improve circulation and blood viscosity.
10. Liver-Supporting Herbs
Over time, toxins and free radicals can cause liver damage that may inhibit the organ’s ability to manage blood cholesterol levels, Dr. Rawls says. So consider looking to herbs such as milk thistle and dandelion, two that are commonly used to promote healthy liver and cellular function.
Working the right herbs, foods, and nutrients into your daily routine can go a long way toward keeping your heart in tip top shape and your cells operating optimally. But consider it just the beginning: If you also feed your heart cells plenty of exercise, give it lots of restful and quality sleep, and protect it from stress and toxins, it will beat loud and strong for you for years to come.
