High cholesterol is a significant health concern in the US, with approximately 10 percent of adults aged 20 and older exhibiting total cholesterol levels exceeding 240 mg/dL, as reported by the Centers for Disease Control and Prevention (CDC). Elevated cholesterol levels are a well-established risk factor for cardiovascular diseases, which are among the leading causes of mortality nationwide.
Cholesterol, a lipid produced by the liver and obtained through dietary sources, is essential for various bodily functions, including hormone production and cell membrane formation. However, an excess of low-density lipoprotein (LDL) cholesterol, often termed “bad” cholesterol, can lead to the accumulation of plaques in arterial walls, increasing the risk of atherosclerosis, heart attacks, and strokes. Conversely, high-density lipoprotein (HDL) cholesterol, known as “good” cholesterol, aids in transporting cholesterol away from the arteries to the liver for excretion. Maintaining a favorable balance between LDL and HDL cholesterol is crucial for cardiovascular health.

Research indicates that plant-based diets are effective in lowering cholesterol levels. A meta-analysis published in the European Heart Journal found that individuals adhering to vegetarian or vegan diets experienced significant reductions in total cholesterol, LDL cholesterol, and apolipoprotein B, a protein associated with LDL particles. Specifically, these diets were associated with a 7-percent reduction in total cholesterol and a 10-percent decrease in LDL cholesterol. The study concluded that plant-based diets have the potential to lessen the atherosclerotic burden from atherogenic lipoproteins, thereby reducing the risk of cardiovascular disease.
How plant-based diets lower cholesterol
Multiple studies have demonstrated the effectiveness of plant-based diets in reducing cholesterol. According to a 2017 study published in the Journal of the American Heart Association, plant-based diets lowered LDL cholesterol levels by an average of 15 percent when compared to omnivorous diets.
A separate meta-analysis published in Progress in Cardiovascular Diseases found that plant-based diets could lower LDL cholesterol by up to 30 percent, comparable to the effect of statin medications. Researchers noted that fiber, plant sterols, and polyunsaturated fats found in plant foods play a critical role in reducing cholesterol levels.
“There is considerable evidence that this type of diet can help lower your risk of developing heart and circulatory diseases by improving cholesterol and blood pressure levels, reducing inflammation, and controlling blood glucose levels,” Tracy Parker, a senior dietitian at the British Heart Foundation in Birmingham said in a statement.
Soluble fiber plays a crucial role in cholesterol reduction by binding to cholesterol in the digestive tract and preventing its absorption. The American Heart Association recommends consuming at least 25 to 30 grams of fiber per day, with a significant portion coming from soluble fiber sources such as oats, beans, fruits, and vegetables.
Plant sterols, naturally occurring compounds found in nuts, seeds, and whole grains, structurally resemble cholesterol and compete with it for absorption in the intestines. Research published in The Journal of Nutrition suggests that consuming 2 grams of plant sterols daily can lower LDL cholesterol by 10 percent.

- Legumes (beans, lentils, chickpeas): Rich in soluble fiber, legumes help reduce LDL cholesterol by binding to cholesterol in the digestive system, facilitating its removal from the body. A study highlighted that legumes are not only protein-rich but also packed with fiber and essential micronutrients like B vitamins, iron, copper, magnesium, and potassium. They benefit heart health by improving cholesterol and vascular health, help stabilize blood sugar levels due to their high fiber and protein content, and foster a healthy gut by promoting a balanced microbiome.
- Nuts and seeds: Almonds, walnuts, flaxseeds, and chia seeds are excellent sources of unsaturated fats, fiber, and plant sterols, which have been shown to lower LDL cholesterol. Regular consumption of these nuts and seeds can improve lipid profiles and reduce cardiovascular risk.
- Whole grains (oats, barley, quinoa): Whole grains are rich in soluble fiber, particularly beta-glucan found in oats, which has been recognized for its cholesterol-lowering effect. In 1997, the FDA recognized the cholesterol-lowering effect of oat beta-glucan. Studies suggest that consuming at least 3 grams of beta-glucan daily can reduce total and LDL cholesterol levels by 5 to 10 percent.
- Fruits and vegetables: High in fiber, antioxidants, and various phytochemicals, fruits and vegetables aid in lowering cholesterol levels. Leafy greens, berries, apples, and citrus fruits are particularly beneficial due to their soluble fiber content and antioxidant properties.
- Soy products: Foods such as tofu, tempeh, and edamame contain soy protein, which has been shown to reduce LDL cholesterol. A meta-analysis reported a 3 to 4-percent reduction in LDL cholesterol from consuming 25 grams of soy protein daily. Consuming edamame may lower cholesterol due to its soy protein and soluble fiber.
Implementing a cholesterol-lowering plant-based diet
Transitioning to a plant-based diet for cholesterol management involves mindful selection of foods and meal planning. Here are practical steps to incorporate these cholesterol-lowering foods into your daily routine.

- Start your day with fiber-rich breakfasts: Opt for oatmeal topped with berries and a sprinkle of chia seeds to provide a hearty dose of soluble fiber. This combination not only aids in lowering LDL cholesterol but also offers a satisfying and nutritious start to your day.
- Incorporate legumes into meals: Add lentils to soups and stews, or enjoy a chickpea salad for lunch. These legumes are versatile and can be seasoned to suit various culinary preferences, making them an easy addition to your diet.
- Snack on nuts and seeds: Keep a handful of almonds or walnuts handy for a quick snack. Incorporate ground flaxseeds or chia seeds into smoothies or sprinkle them over salads and cereals to boost your intake of heart-healthy fats and fiber.
- Choose whole grains: Replace refined grains with whole grains such as quinoa, barley, or whole-wheat products. These grains provide more fiber and nutrients, contributing to better cholesterol management.
- Embrace soy-based foods: Incorporate tofu into stir-fries, enjoy edamame as a snack, or add tempeh to grain bowls for a satisfying and protein-rich meal. These soy-based options not only provide high-quality plant protein but also contribute to lowering LDL cholesterol levels.
- Increase vegetable intake: Fill half your plate with a variety of colorful vegetables at every meal. Leafy greens like spinach and kale, as well as cruciferous vegetables such as broccoli and Brussels sprouts, are particularly beneficial due to their fiber and antioxidant content.
- Opt for plant-based fats: Replace saturated fats found in dairy and meat with heart-healthy fats from sources such as avocados, extra virgin olive oil, and nuts. These healthy fats support cardiovascular health without raising LDL cholesterol levels.
