Atherosclerosis is a systemic disease that affects the entire arterial vascular tree. It is caused by an imbalance in cholesterol intake, which is deposited in the blood vessels, causing them to harden and narrow, impairing blood flow. Lifestyle modifications are key to preventing atherosclerosis and other conditions. A healthy diet and regular exercise can help lower cholesterol levels, control weight, and improve blood circulation, thereby reducing the risk of atherosclerosis and its associated complications, such as heart attacks and strokes.

What You'll Learn
A Mediterranean diet can help prevent atherosclerosis
Atherosclerosis is a systemic disease that affects the entire arterial vascular tree. It is caused by an imbalance in cholesterol intake, which gets deposited in the blood vessels, inflaming and hardening them. This can lead to strokes, heart attacks, amputation, and even death. While surgery can lessen some of the acute damage, lifestyle modifications are critical to preventing other conditions from occurring.
Diet and exercise play a significant role in managing atherosclerosis. A Mediterranean diet, in particular, can help prevent atherosclerosis. This dietary pattern is high in fruits and vegetables, legumes, and whole grains. It is also rich in extra virgin olive oil, oily fish, and nuts. Compared to a low-fat diet, long-term consumption of a Mediterranean diet is associated with decreased atherosclerosis progression. This is evident from reduced intima-media thickness (IMT) measures and carotid plaque height.
The Mediterranean diet is defined as 35% fat, 22% monounsaturated fatty acids (MUFAs), and less than 50% carbohydrates. It increases fiber and total fat intake, including MUFAs and polyunsaturated fatty acids (PUFAs), while reducing saturated fatty acids, total carbohydrates, and cholesterol. This diet also lowers the intake of red meats and processed foods, which are typical of the Western diet often high in fat and cholesterol.
In addition to the Mediterranean diet, other dietary strategies can help reduce the risk of atherosclerotic cardiovascular disease (ASCVD). These include limiting animal products, saturated fats, and cholesterol intake. Eating antioxidant-rich foods, such as vegetables and fruits, can also contribute to maintaining a healthy oxidant/antioxidant balance in the body, which plays a role in the development of atherosclerotic diseases.
Exercise is another crucial component of managing atherosclerosis. It is recommended to engage in 30 to 45 minutes of physical activity, 4 to 5 days a week. This helps improve overall health, manage stress, and maintain an active lifestyle, all of which contribute to preventing and managing atherosclerosis.

Polyphenols and flavonoids reduce inflammation
Atherosclerosis is a systemic vascular disease that affects the entire arterial vascular tree. It is caused by an imbalance in cholesterol intake, which is deposited in the blood vessel, inflaming and hardening it. High cholesterol, stress, diabetes, and high blood pressure contribute to the development of atherosclerosis. The typical Western diet—high in fat and cholesterol and low in fiber—also contributes to the disease.
Lifestyle modifications are key to preventing atherosclerosis. This includes maintaining a healthy diet and exercising. A heart-healthy diet should include fresh or frozen fruits and vegetables, whole grains, lean meats, low-fat dairy products, nuts, seeds, and legumes, and should limit sodium, saturated fats, trans fats, refined carbohydrates, and alcohol.
Polyphenols and flavonoids are natural compounds with anti-inflammatory and antioxidant properties that can help reduce inflammation associated with atherosclerosis. Polyphenols are found in plant-based foods and exhibit a number of beneficial properties for health, including antioxidant, anti-inflammatory, antibacterial, and neuroprotective activities. Flavonoids are a type of natural polyphenol compound widely found in fruits, composed of two aromatic rings with a typical C6-C3-C6 skeleton.
The anti-inflammatory properties of polyphenols and flavonoids play a crucial role in reducing the inflammation associated with atherosclerosis. Flavonoids can inhibit the activity of 5-lipoxygenase (5-LOX) and cyclooxygenase (COX, especially COX-2), which are involved in the inflammatory process. Additionally, flavonoids can decrease oxidative stress and increase nitric oxide (NO) bioavailability, contributing to their vascular benefits and protection against atherosclerosis. The ability of flavonoids to reduce NO oxidation and increase NO bioavailability is significant in protecting the cardiovascular system and improving the condition of blood vessels.
Studies have shown that a diet rich in flavonoids can significantly reduce CVD mortality, which is directly related to atherosclerosis. Flavonoids can reduce cholesterol transport and enhance immune function by regulating intracellular inflammatory factors. The prevalence of flavonoids in plant-derived foods has sparked interest in their potential health benefits, leading to new research on their ability to protect against cardiovascular risk factors.

Exercise can help prevent heart disease
Atherosclerosis is a systemic disease that affects the entire arterial vascular tree. It is caused by a buildup of cholesterol and fat, which inflames and hardens the arteries. This can lead to strokes, heart attacks, and even death. While medication and surgery can help lessen the damage, lifestyle modifications, including exercise, are key to preventing atherosclerosis and other conditions.
Additionally, regular exercise helps reduce the amount of fat in your blood and lowers cholesterol, which is a major cause of atherosclerosis. By controlling your weight and reducing fat and cholesterol levels, you can help prevent the buildup of fatty substances in your arteries, slowing or blocking the flow of oxygen-rich blood to vital organs.
To maintain heart health, it is recommended to get at least 30 minutes of moderate aerobic exercise most days of the week. This can include brisk walking, swimming, or cycling. You can also split this into 10-minute segments if needed. However, more physical activity will yield even more health benefits, and some guidelines suggest up to 2 hours and 30 minutes of moderate aerobic exercise each week.
Along with exercise, maintaining a healthy diet is crucial. This includes limiting animal products, saturated fats, sodium, sugar, and alcohol consumption. Instead, focus on consuming fruits, vegetables, and grains, whole grains, lean meats, low-fat dairy products, nuts, seeds, and legumes.

A diet with plant sterols can help
Atherosclerosis is a systemic disease that affects the entire arterial vascular tree. It is caused by an imbalance in cholesterol intake, which is deposited in the blood vessels, causing inflammation and hardening. High cholesterol, stress, diabetes, and high blood pressure contribute to the development of atherosclerosis. While surgery can help lessen some of the damage, lifestyle modifications are key to preventing other conditions from occurring.
When the body digests plant sterols instead of cholesterol, some of the cholesterol is removed as waste, resulting in lower cholesterol levels. This can be especially beneficial for individuals with high cholesterol levels or a family history of heart disease. However, it is important to note that phytosterols are not recommended for people with sitosterolemia, a genetic disorder where cholesterol and plant sterols build up in the body.
Functional foods enriched with plant sterols have become a popular non-prescription approach to lowering cholesterol. While the cholesterol-lowering effect of plant sterol supplementation is well-established, studies investigating the impact on various markers of atherosclerosis have shown controversial results. Some studies have linked elevated plasma concentrations of circulating plant sterols with the presence of cardiovascular disease, raising concerns about the safety of phytosterol supplementation.
Overall, a diet with plant sterols can be beneficial for managing atherosclerosis by helping to lower cholesterol levels. However, it is always recommended to consult with a healthcare provider before making any significant dietary changes or taking supplements.

Avoid trans fats, processed meats, refined carbs, and sugar
Atherosclerosis is a buildup of plaque in the heart's arteries, which can lead to heart attacks and strokes. A heart-healthy diet and regular exercise are key to preventing this condition.
Avoid Trans Fats
Trans fats have been causally linked to atherosclerosis. They are composed of trans-fatty acids (TFAs) which are produced industrially during the hydrogenation of unsaturated oils. TFAs suppress TGF-β responsiveness in the aortic endothelium, leading to atherosclerotic lesions. Trans fats are often found in fried foods, baked goods, margarine, frozen pizzas, and microwave popcorn.
Avoid Processed Meats
Consumption of processed meats has been associated with a higher risk of atherosclerotic cardiovascular disease (ASCVD). This is due in part to the presence of L-carnitine and choline, which are abundant in red meat and can lead to elevated blood glucose, insulin, and C-reactive protein levels.
Avoid Refined Carbohydrates
Low-carbohydrate diets have been linked to an increased risk of atherosclerosis. While these diets can help with weight loss, they may negatively impact vascular health. It is important to maintain a moderate and balanced diet that includes healthy carbohydrates such as whole grains, fruits, and vegetables.
Avoid Sugar
Sugar, specifically the natural sugar trehalose, has been found to reduce atherosclerotic plaque buildup in mice. Trehalose triggers an important cellular housekeeping process in immune cells called macrophages, which are responsible for cleaning up cellular waste, including excess fat droplets. However, more research is needed to determine the effectiveness of trehalose in humans, as it currently requires injections to remain stable in the body.
