20 Foods That Can Help Unclog Your Arteries
Updated: Jul. 09, 2019
You're never too young to start eating for your arteries—blockages can start early. Science shows that these foods could be your ticker's best friend.
Keep your heart healthy
Heart disease is the second leading cause of death in Canada: According to the Government of Canada, “every hour, about 12 Canadian adults age 20 and over with diagnosed heart disease die.” The cause is clogged arteries, and things like calcium, plaque, and fatty acids can do the damage. “There is no one magic food that acts like Drano and cleans out the accumulated plaque,” says Florian Rader, MD, a cardiologist at the Smidt Heart Institute at Cedars-Sinai Medical Center in Los Angeles. “But good habits can help slow down that process, and maintaining a healthy weight and diet is one factor you can control to a great degree. And,” he says, “It’s never too late to start.”
Oats
Here’s a step for how to unclog arteries: Research keeps uncovering new benefits of eating heart-healthy whole grains. The main one, says Bonnie Taub-Dix, RD, author of Read It Before You Eat It: Taking You from Label to Table, is their rich supply of soluble fibre, which has been shown to lower bad LDL cholesterol levels. Why that’s good for your arteries, according to Dr. Rader: “Cholesterol can seep into the inner layer of blood vessels and form plaque over time.” Since most Canadians fall chronically short on fibre, the four grams per cup that oats deliver are a welcome addition. Check out these other foods that lower cholesterol naturally.
Beans
In addition to being a great source of soluble fibre—black beans have three times as much of it per cup as oats—studies have found that bean-rich diets may help make arteries more elastic, contributing to lower blood pressure. Another perk: Antioxidants, which are especially abundant in colorful varieties such as black beans and red kidney beans, may fight the inflammation that contributes to heart disease. Don’t miss these 25 secrets your cardiologist wants you to know.
Lentils
These protein-packed discs come from the same legume family as beans, which means that they pack many similar benefits. Preliminary research in rats found that lentils appear to reverse the damage to blood vessels caused by high blood pressure. Plus, lentils are at the top of the food spectrum for protein and fibre content, with very little fat, and contain calcium, potassium, and magnesium—all minerals that can help lower blood pressure. Beware: This common type of stress could give you a heart attack.
Fish
A lot of the research on omega-3 fatty acids focuses on brain health, but these potent anti-inflammatories have benefits for your ticker, too. Research links inflammation inside your body to a number of chronic diseases and conditions, including plaque buildup, says Dr. Rader. So there’s speculation that reducing inflammation might reduce plaque in your arteries. Eating fatty fish such as salmon and mackerel is one way to get your fill of omega-3s, so try to eat some at least twice a week, says Taub-Dix. Don’t miss these 7 signs you might be headed for a heart attack.
Avocados
Fat of any kind used to be at the top of the list of things that are bad for your heart. Not anymore: Research reveals that mono- and polyunsaturated fats, like those found in avocados, are heart healthy because they help lower bad LDL cholesterol and raise good HDL cholesterol, says Taub-Dix. These green fruits also contain a decent amount of fibre. Read more about the heart-healthy benefits of avocados.
Pistachios
Nuts are another good way for how to unclog arteries because they are a good source of heart-healthy fats, and pistachios have this bonus: They’re filled with plant sterols, the same substances in cholesterol-lowering products that help block cholesterol absorption in your gut, says Karen Ansel, RD, author of Healing Superfoods for Anti-Aging: Stay Younger, Live Longer. If you’re allergic to nuts, you can also get plant sterols from sesame seeds.
Turmeric
In recent years, more people have started recognizing the health-boosting properties of this brilliant yellow spice traditionally used in Indian cuisine. A substance in the spice, curcumin, is an antioxidant that may help prevent fatty deposits from building up and blocking arteries, Ansel says. If you’re not a huge fan of curry, try a golden latte made with the spice.
Broccoli
Scientists have known for years that cruciferous veggies like broccoli have cancer-fighting abilities, but researchers are also examining broccoli’s role in heart health. There’s evidence that a compound in it called sulforaphane may assist the body’s natural defenses against arterial clogs by activating a certain kind of protein, says Ansel. Broccoli also has fibre and anti-inflammatory properties. Read about how this and other foods can help lower blood pressure.
Asparagus
Another green giant as far as heart health goes, these fibrous stalks are rich in quercetin, a phytonutrient that prevents plaque from sticking to your arteries. “Whether you have a family history of heart disease or are simply trying to prevent it, asparagus should be at the top of your shopping list,” Ansel says. Here’s what doctors do to lower their cholesterol.
Watermelon
The reason cardiologists seem obsessed with taking your blood pressure? When it’s elevated, it can eventually wear out the lining of your blood vessels, leaving them less elastic and able to function normally. That can increase your risk for a heart attack or stroke. This juicy melon can help. “Watermelon is the number one source of citrulline,” says Ansel. Citrulline is an amino acid the body uses to produce nitric oxide, which helps keep your blood vessels relaxed and pliable. These are the supplements doctors take every day.
Whole grains
You’ve been told for years that carbs are bad. But whole grains—even in bread and pasta—can be part of a heart-healthy diet and a step in how to unclog arteries. According to an analysis published in the Archives of Internal Medicine, for every ten grams of whole grains people eat each day, their risk of heart disease dropped 14 percent; even better, their odds of dying from a heart attack fell 25 percent. This may be because whole grains are loaded with fibre, says Angela Lemond, RD, a Plano, Texas-based nutritionist and national spokesperson for the Academy of Nutrition and Dietetics. “Fibre helps pull cholesterol out of the body. It is also known to help promote the growth of good bacteria in the gut, which can have an indirect benefit on heart health.” Try swapping refined grains for unprocessed ones to reap the benefits. And watch for these signs of a stroke you might be missing.
Milk with DHA
As aging arteries stiffen up, says Lemond, they can begin to restrict your blood flow. Omega-3 fatty acids help maintain vessel elasticity—especially one known as docosahexaenoic acid (DHA). It’s most commonly found in seafood, but if you’re not a fish fan, try DHA-fortified milk and eggs. Here are 7 signs you might have clogged arteries.
Potatoes
Yes, you can have potatoes—just not all the time. Spuds are full of potassium: They give you more than double the amount in an average banana. That’s key because only 3 percent of Americans are getting their RDA of potassium, and it’s helpful in regulating your blood pressure. Potatoes also have a decent amount of fibre, so as long as you don’t deep-fry them or slather them in butter and sour cream, they can be a surprisingly healthy choice.

Chocolate
How to unclog arteries? Indulge in some chocolate. Cocoa beans are rich in flavanols—plant compounds that have antioxidant properties and may benefit your heart. A 2017 analysis of the research done on chocolate published in the journal Nutrients found that people who regularly ate chocolate (in moderation) had a lower risk of heart failure. Nutritionists recommend dark chocolate over other types—that high cacao percentage (above 70 percent) means the bar has more beneficial compounds. Find out what your hands can reveal about your health.
Coffee
Like a lot of beans, coffee beans—and the java you get from them—deliver healthy antioxidants. In research, coffee seems to lower the incidence of cardiac disease; the caffeine may also help your ticker. When scientists recently gave mice the caffeine equivalent of four cups of coffee, they discovered that the cells lining the mice’s blood vessels began to work more efficiently. But if you’re thinking about quitting coffee, watch for these 10 things that will happen to your body.
Wine
While most nutritional guidelines acknowledge that a little wine (and other types of alcohol) in moderation may be good for your heart, they do so with a strong caution, says Dr. Rader. He points out that there’s no direct cause and effect—researchers haven’t established that drinking wine lowers your risk; they only know that people with a lower risk of heart disease tend to drink wine. That’s why no one is handing out free passes to drink as much as you want: Limit yourself to no more than one four-ounce glass of wine a day if you’re a woman—two for men. Although you might get similar benefits with any type of alcohol, you may want to stick with the red wine: It has an anti-aging compound called resveratrol, which also helps lower inflammation.
Eggs
Yep, science really messed up this one: Heart specialists used to warn people to stay away from eggs because they have a lot of cholesterol. But the research is now pretty clear that the cholesterol in your food has very little impact on the levels in your blood, says Taub-Dix. In fact, fats in eggs seem to boost the good HDL cholesterol in your blood (it helps prevent the buildup of plaque in vessel walls). A study published in the journal Heart found that eating eggs daily was associated with an 11 percent drop in the risk for heart disease. But one thing you should limit is salt. Here are 7 signs you’re consuming too much salt.
Berries
They’re fibre- and antioxidant-rich, and one study, published in Circulation: The Journal of the American Heart Association, found that eating three servings a week may slash the risk of a heart attack by a third in women. Researchers credit anthocyanins, compounds in berries that may help dilate blood vessels, making it easier for blood to pass through.
Green tea
Benefits abound in this brew—and British researchers recently found an exciting new bonus: They were focusing on a compound known as EGCG, which has shown promise in treating Alzheimer’s disease. The researchers found that the same molecule could shrink fatty deposits on artery walls. In previous research, scientists demonstrated that green tea could lower bad LDL cholesterol and triglycerides, too. How do they do it!? Here’s what the world’s healthiest people have in common.
Fermented foods
Probiotics get a lot of attention because they support the populations of healthy bacteria in your gut. But did you know that you can repopulate your intestines with the good healthy bacteria found in foods like kimchi, yogurt, and kombucha? Emerging research indicates that the foods (and the bacteria they contain) may help lower your blood pressure and bad LDL cholesterol levels. Next, discover 15 things you didn’t know could literally slow down aging.
