Atherosclerosis, commonly referred to as clogged arteries, is caused by the buildup of plaque along the arterial wall. This causes the arteries to narrow and restrict blood flow to the heart and other parts of the body. While there are medications to treat this, diet and lifestyle changes can also help prevent and manage the condition. A healthy diet that includes foods rich in antioxidants, omega-3 fatty acids, and other beneficial compounds may help prevent plaque buildup in your arteries.

The DASH diet: vegetables, fruits, whole grains, lean meats, fish, poultry, low-fat dairy
While there are no specific foods that can reverse plaque buildup in arteries, certain diets can help manage and prevent heart disease. The DASH diet, which stands for Dietary Approaches to Stop Hypertension, is one such diet that can help improve heart health.
The DASH diet emphasizes eating plenty of vegetables and fruits. It is recommended to opt for whole grains instead of refined grains and choose fat-free or low-fat dairy products. The diet also includes lean protein sources such as fish, poultry, and beans. It is advised to cook with vegetable oils and limit the intake of foods high in added sugars and saturated fats.
On the DASH diet, you can expect to eat a lot of vegetables and fruits. Examples of vegetables include broccoli, carrots, squash, and tomatoes, while apples, pears, peaches, berries, and tropical fruits are some of the fruits you can enjoy. For whole grains, choose options like whole-wheat bread, whole-grain cereals, brown rice, bulgur, quinoa, and oatmeal.
When it comes to lean protein sources, the DASH diet includes fish, poultry, and beans. It is recommended to choose lean cuts of meat and limit red meat consumption to only occasional servings, ideally no more than once or twice a week. Low-fat dairy products such as skim milk, low-fat cheese, and yogurt are also part of the DASH diet.
The DASH diet is not just beneficial for managing heart health but also offers a number of potential advantages. Numerous studies have found it effective in reducing blood pressure and lowering body fat, especially in older adults with obesity. Additionally, following the DASH diet has been linked to a lower risk of certain types of cancer.

Mediterranean diet: olive oil, dark leafy greens, berries, nuts, moderate cheese and wine
The Mediterranean diet is characterised by the high consumption of fruits, vegetables, and salads, bread and whole grain cereals, potatoes, legumes/beans, nuts, and seeds. Dairy products, such as cheese and yoghurt, fish, shellfish, and poultry are consumed in low to moderate amounts. Eggs are eaten up to four times a week, and red and processed meat is rarely eaten. The Mediterranean diet is also known for its inclusion of wine and its usage of olive oil as the main source of fat.
Olive oil, a key component of the Mediterranean diet, is known for its health benefits. It is high in nutritional quality and has multiple positive effects on health. Olive oil is rich in mono-unsaturated fatty acids, tocopherols, and polyphenols, which have direct effects on the immune system and inflammatory responses.
Dark, leafy greens are another important feature of the Mediterranean diet. They are nutritional powerhouses, supplying vitamins A, C, E, and K, as well as an abundance of antioxidants, fibre, iron, magnesium, potassium, and calcium. Leafy greens may help improve heart health, regulate insulin, and manage weight, making them an important component of a diet aimed at improving heart health and reducing plaque in arteries.
Nuts are also a staple of the Mediterranean diet, with study participants consuming three or more servings of nuts weekly. Nuts are calorie-dense, so they should be consumed in small amounts. Berries are another important component of the Mediterranean diet, as they contain fibre, vitamins, minerals, and beneficial plant compounds. Berries have been shown to reduce inflammation and cholesterol accumulation, thereby improving artery function and protecting against cellular damage.
Wine is typically consumed with meals on the Mediterranean diet. Study participants drank seven or more glasses of red or white wine per week, or about one drink per day. Research has found that a Mediterranean diet including alcohol reduced the risk of cardiovascular disease by 30% compared to a low-fat diet without alcohol. However, it is important to consider the potential harms of alcohol, especially for younger individuals. For those under 35 years of age, it is recommended to remove wine from the Mediterranean diet.

Plant-based diets: whole foods, vegetables, fruits, grains, legumes, nuts, seeds, beans, soy protein
A plant-based diet that focuses on whole foods can help slow coronary artery disease progression and reduce the risk of atherosclerosis. This is because a plant-based diet can help lower blood pressure, lower "bad" cholesterol levels, and maintain a healthy weight.
Whole foods, vegetables, fruits, grains, legumes, nuts, seeds, beans, and soy protein are all part of a plant-based diet. This diet focuses on consuming foods in their most natural form, excluding heavily processed foods. When purchasing groceries, opt for fresh foods and items with few ingredients.
- Fill half your plate with vegetables at lunch and dinner. Include a variety of colourful vegetables, such as kale, spinach, tomatoes, broccoli, cauliflower, carrots, asparagus, and peppers.
- Enjoy vegetables as a snack with hummus, salsa, or guacamole.
- Reduce your meat consumption. If you choose to eat animal products, have smaller amounts and use them as a garnish instead of the main dish.
- Choose healthy fats like olive oil, olives, nuts and nut butters, seeds, and avocados.
- Include whole grains for breakfast, such as oatmeal, quinoa, buckwheat, or barley.
- Add greens like spinach or kale to your daily meals.
- Swap out meat in recipes for plant-based options like black beans, tofu, or tempeh.
- Include fruits like berries, citrus fruits, pears, peaches, pineapple, and bananas.
- Legumes such as peas, chickpeas, lentils, and peanuts are a great source of protein and can be included in meals or snacks.
- For calcium, include tofu, tahini, and leafy greens in your diet.
By following these guidelines and focusing on whole, plant-based foods, you can improve your health and reduce your risk of atherosclerosis and associated coronary diseases.

Omega-3 fatty acids: fatty or oily fish like salmon and tuna, nuts, seeds, beans
Omega-3 fatty acids are essential for maintaining heart health and preventing clogged arteries. They can be obtained from fatty or oily fish like salmon, tuna, herring, and sardines. These long-chain omega-3 fatty acids have been shown to stabilize vulnerable atherosclerotic plaques and even reverse atherosclerosis. Studies have found that patients with acute coronary syndrome have significantly lower levels of omega-3 fatty acids like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in their system. Increasing the consumption of these fatty acids can reduce the risk of death from cardiac and non-cardiac causes.
The body can metabolize omega-3 fatty acids into bioactive lipid mediators, which may reduce inflammation and blood clotting, both of which contribute to clogged arteries. Additionally, omega-3 fatty acids derived from fish oil have been found to induce changes that enhance the stability of atherosclerotic plaques. They can reduce the prevalence of thin fibrous caps, which are associated with an increased risk of rupture, and increase the thickness of fibrous caps, making plaques less vulnerable.
Nuts and seeds are excellent sources of omega-3 fatty acids, along with protein, fiber, healthy fats, vitamins, and minerals. Incorporating nuts and seeds into your diet can help reduce LDL (bad) cholesterol and boost HDL (good) cholesterol, contributing to better heart health and reduced risk of atherosclerosis. Some nuts and seeds, like flax seeds, are especially beneficial due to their high fiber and nutrient content, including calcium and magnesium.
Beans are another excellent source of omega-3 fatty acids and are known for their ability to manage cholesterol levels. Studies have shown that consuming beans can significantly reduce LDL (bad) cholesterol, which is a crucial factor in preventing atherosclerosis and maintaining healthy arteries.

Antioxidants: avocado, berries, citrus fruits, dark chocolate, green and yellow vegetables
While it is not possible to make plaque disappear, certain foods can help prevent clogged arteries and lower your risk of heart disease. Atherosclerosis, commonly referred to as clogged arteries, is caused by the narrowing of arteries due to plaque buildup, which restricts blood flow to the heart and other parts of the body.
A diet rich in antioxidants, omega-3 fatty acids, and other beneficial compounds may help prevent plaque from forming in your arteries. Here are some antioxidant-rich foods that can help:
Avocados
Avocados are a great way to clean out your arteries. They are a rich source of monounsaturated fatty acids (MUFAs) and polyphenol antioxidant compounds. Research shows that diets rich in MUFAs are associated with an increase in "good" HDL cholesterol and a reduction in "bad" LDL cholesterol.
Berries
Berries contain fibre, vitamins, minerals, and beneficial plant compounds, including flavonoid antioxidants and polyphenols. These compounds have powerful anti-inflammatory and antioxidant effects, which help keep arteries clear and healthy. They also help improve LDL cholesterol, blood pressure, and blood sugar control.
Citrus Fruits
Citrus fruits, such as oranges, are packed with polyphenol compounds called flavonoids, which have powerful antioxidant properties. These citrus bioflavonoids scavenge free radicals that might otherwise cause oxidative stress and drive disease processes. They also provide a variety of vitamins, minerals, and antioxidants, including flavonoids, which can decrease inflammation and help prevent free radicals in the body from oxidizing LDL (bad) cholesterol.
Dark Chocolate
Dark chocolate is known to be rich in antioxidants, which can help improve heart health.
Green and Yellow Vegetables
Green and yellow vegetables, such as perilla, are popular in Japan and China and are known to be rich in polyphenols and to have strong antioxidant activity against LDL oxidation. They also contain abundant quantities of carotenoids, vitamin C, and vitamin E, which are believed to contribute to the prevention of atherosclerotic diseases.
