Atherosclerosis, or clogged arteries, is a cardiovascular condition that involves the buildup of plaque along the arterial wall, causing the arteries to narrow and harden. While there are medical procedures to remove plaque, such as inserting a stent or bypass surgery, there is no quick fix for melting it away. However, making key lifestyle changes, such as improving your diet, can help stop plaque from accumulating and improve your heart health.
How to reduce blockage in arteries through diet:
| Characteristics | Values |
|---|---|
| Reduce saturated fats | Consuming saturated fats increases LDL cholesterol, which directly causes heart issues. |
| Increase unsaturated fats | Unsaturated fats contain HDL cholesterol, which helps to remove bad cholesterol from the arteries before it turns into plaque. |
| Reduce red meat, sugar and salt | The American Heart Association (AHA) recommends limiting these foods when aiming to lower LDL cholesterol. |
| Eat more vegetables | The DASH diet recommends eating more vegetables, fruits and whole grains. |
| Eat more leafy greens | Spinach, kale, arugula, Swiss chard, and lettuce are good sources of dietary nitrates, which improve blood vessel function and reduce inflammation. |
| Eat more cruciferous vegetables | Broccoli, cabbage, and cauliflower are associated with a decreased risk of atherosclerosis. |
| Eat more tomatoes | Tomatoes contain lycopene, which studies show may help to reduce the development of atherosclerosis. |
| Eat more onions | Onions are linked to supporting artery health and may help prevent blood vessel inflammation. |
| Eat more nuts and seeds | These are excellent sources of protein, fibre, healthy fats, vitamins, and minerals, and may help to improve blood vessel function. |
| Drink herbal teas | Green tea helps to lower total cholesterol and LDL cholesterol. |

What You'll Learn
Consume more leafy greens, nuts, and seeds
Consuming leafy greens, nuts, and seeds is a great way to improve your heart health and reduce the risk of clogged arteries. Atherosclerosis, commonly known as clogged arteries, occurs when fatty deposits accumulate along the artery walls, restricting blood flow to the heart and other body parts.
Leafy greens are a fantastic source of dietary nitrates, which play a crucial role in improving blood vessel function and reducing inflammation. Aim for a daily serving of leafy greens such as lettuce, kale, arugula, Swiss chard, and spinach. These vegetables are also packed with potassium, a mineral that helps prevent vascular calcification, a process contributing to atherosclerosis.
Nuts and seeds are versatile and nutritious foods that offer numerous benefits for heart health. They are excellent sources of protein, fiber, healthy fats, vitamins, and minerals. Eating nuts and seeds can effectively lower LDL (bad) cholesterol and increase HDL (good) cholesterol, contributing to a healthier cholesterol profile. Additionally, they help lower systolic blood pressure and reduce blood sugar levels, which may protect against diabetes, a risk factor for atherosclerosis. Include a variety of nuts and seeds in your diet, such as flax seeds, which are rich in fiber, calcium, and magnesium.
The combination of nutrients in leafy greens, nuts, and seeds creates a powerful defense against clogged arteries and improves overall cardiovascular health. By incorporating these foods into your diet, you can actively support the health of your arteries and reduce your risk of heart disease. Remember to vary your diet and include other heart-healthy foods, such as cruciferous vegetables, berries, and oats, for a well-rounded approach to maintaining a healthy cardiovascular system.

Reduce saturated fats and replace with unsaturated fats
While some sources suggest that saturated fat does not directly contribute to clogged arteries, it is still recommended to limit your intake. Saturated fats are mostly solid at room temperature and are usually derived from animal products, such as meat, poultry, and full-fat milk. These fats can increase your low-density lipoprotein (LDL) cholesterol, which is a bad type of cholesterol that can clog your arteries.
Unsaturated fats, on the other hand, are mostly liquid at room temperature and are primarily derived from plants and fatty fish. They are considered a healthier alternative as they can help reduce LDL cholesterol levels and increase high-density lipoprotein (HDL) cholesterol, which is good for your body. HDL cholesterol helps to remove bad cholesterol from your arteries before it turns into plaque, thereby preventing blockages.
To reduce saturated fat intake, you can make some simple swaps. For example, instead of using butter, which is high in saturated fat, opt for extra-virgin olive oil, which is rich in unsaturated fats and has anti-inflammatory properties. Avocados, olives, and nuts are also excellent sources of unsaturated fats and can be easily incorporated into your diet. Additionally, consider including more eggs in your meals as they contain more unsaturated fat than saturated fat, and their cholesterol is now believed to not increase LDL levels. Dark chocolate lovers can also rejoice, as it too contains unsaturated fats, along with fiber, iron, and magnesium. However, moderation is key when it comes to dark chocolate, as it is calorie-dense.
By making these small changes and choosing unsaturated fats over saturated fats, you can help improve your blood cholesterol levels and reduce your risk of clogged arteries.

Eat more cruciferous vegetables
Eating more cruciferous vegetables is a great way to improve your heart health and reduce the risk of clogged arteries. Cruciferous vegetables are known to be rich sources of vitamin K, which is essential for cardiovascular health.
Cruciferous vegetables include broccoli, cabbage, cauliflower, Brussels sprouts, bok choy, and other green leafy vegetables. These vegetables are particularly beneficial for heart health due to their ability to reduce artery plaque and lower blood pressure. A 2020 study published in the British Journal of Nutrition found that consuming cruciferous vegetables reduced the risk of blood vessel disease and the build-up of plaque on the arteries. The study followed 684 Western Australian women over a 20-year period and found that those who ate more cruciferous vegetables had less fat and calcium build-up on their aorta blood vessel.
Another study from the University of Western Australia in Perth found that older women who consumed more cruciferous vegetables had thinner carotid artery walls, which is significant as it reduces the risk of stroke and heart attack. Furthermore, a study from Tokyo's Epidemiology and Prevention Group, Center for Public Health Sciences, followed 88,184 people for nearly 17 years and found that those who consumed more cruciferous vegetables had a reduced rate of death.
To incorporate more cruciferous vegetables into your diet, try adding broccoli, cabbage, or cauliflower to your meals. These vegetables can be steamed, roasted, or stir-fried and make a great addition to salads, bowls, or as a side dish. Aim for at least 45 grams of cruciferous vegetables daily, which is equivalent to about a quarter cup of steamed broccoli or half cup of raw cabbage.
In addition to their heart-health benefits, cruciferous vegetables are also packed with nutrients and offer many other health benefits. They are a good source of dietary nitrates, which can help improve blood vessel function and reduce inflammation. They are also high in fiber, which can help lower cholesterol and improve digestive health.

Drink herbal teas like green tea
Drinking herbal teas, such as green tea, can be a beneficial addition to your diet when it comes to reducing blockage in your arteries. Green tea is a light, aromatic tea that has been linked to improved cardiovascular health.
Research suggests that drinking green tea may help lower total cholesterol and LDL (bad) cholesterol levels. A 2011 review found that consuming green tea enriched with catechins resulted in a small reduction in cholesterol levels. Similarly, a 2013 review of 11 studies indicated that drinking green tea daily could help lower cholesterol and blood pressure. However, most of the studies included in this review were short-term, and the authors recommended longer-term trials to confirm these findings.
The potential cholesterol-lowering effects of green tea are significant because high cholesterol, particularly LDL cholesterol, is a risk factor for atherosclerosis. Atherosclerosis is a condition where plaques of cholesterol, fat, and other substances build up inside your arteries, narrowing them and reducing blood flow. By helping to lower LDL cholesterol, green tea may contribute to reducing the risk of atherosclerosis and improving artery health.
It is worth noting that the compound in green tea responsible for its potential cholesterol-lowering effects is called epigallocatechin gallate (EGCG). However, to achieve effective amounts of EGCG in the bloodstream, one would need to consume very large quantities of green tea, which is not recommended. Researchers are exploring ways to enhance the absorption and effectiveness of EGCG, such as modifying its chemical structure or delivering it directly to the plaques.
In addition to its potential cholesterol-lowering properties, green tea may also offer other benefits for cardiovascular health. Studies suggest that green tea may help lower blood pressure and reduce arterial stiffness, further contributing to a reduced risk of cardiovascular issues. For example, a 2014 survey of data from previous studies found a small reduction in blood pressure for individuals with high blood pressure who consumed green tea.
In conclusion, while drinking green tea may not be a cure-all solution, incorporating it into your diet can be a beneficial step towards improving your cardiovascular health and reducing the risk of artery blockages. However, it is important to consume green tea in moderation, as excessive intake may have more risks than benefits. Combining green tea consumption with other heart-healthy lifestyle habits, such as a balanced diet, regular exercise, stress management, and not smoking, will help maximize its potential benefits.

Exercise regularly
Exercise is one of the best ways to maintain artery health and prevent blockages. It can be like a "super-pill", reducing cholesterol and blood pressure. Any type of exercise is beneficial, but aerobic exercise, or cardio, is particularly good for arterial health. When your heart rate is elevated during cardio, it pumps more blood through your arteries, keeping them wider and more flexible, and reducing the likelihood of plaque buildup.
Examples of aerobic exercise include walking, running, dancing, rowing, and swimming. Strength training is also important for arterial health. To improve your vascular health, try to incorporate different types of exercise, such as tennis, yoga, or weightlifting, into your routine to prevent boredom and keep things interesting.
Italian researchers have found that in people who exercised regularly, age had a much smaller effect on their arteries. The nitric oxide produced by endothelial cells in the arteries declines with age, but exercise helps to boost its production, keeping the arterial lining smooth and preventing damaging inflammation and artery-blocking blood clots. It also relaxes the smooth muscle cells of the artery wall's middle layer, preventing spasms and keeping arteries open.
Exercising muscles need more blood, and in response to regular exercise, they grow more blood vessels by expanding the network of capillaries. This, in turn, improves metabolism, helping to control blood sugar, burn fat, and maintain or decrease body weight. With healthy arteries, you have a lower risk of high blood pressure, high cholesterol, and heart failure, reducing your chances of cardiovascular events such as cardiac death, stroke, and heart attack.
Even if you are sedentary, it's never too late to start exercising. Just 2-3 miles of brisk walking nearly every day can be a giant step in the right direction.
