Top 10 Cholesterol Lowering Foods

Cholesterol is a steroid lipid (fat) found in the blood and is necessary for proper functioning of cell membranes. Our bodies already make all the cholesterol we need, so it is not necessary to consume more. High levels of cholesterol increase the risk of heart disease and stroke. (1)

Cholesterol-lowering foods should be incorporated into everyone's diet for optimal health. Different diets, lifestyles, and foods will work differently for different people. It is recommended that you buy a Cholesterol Test Kit, so you can monitor your cholesterol levels at home and see which diet and lifestyle work best for you.

Cholesterol-lowering foods include oat bran, flax seeds, garlic, almonds, walnuts, whole barley, and green tea. Below is a detailed list of foods which lower bad LDL cholesterol, while leaving the good HDL cholesterol largely unaffected.


List of Cholesterol Lowering Foods

1Monounsaturated and Polyunsaturated Fats (Olive Oil, Canola Oil, Peanut Oil, Peanuts, Olives, Avocados)
Green Olives
Cholesterol Reduction: 18%
Substituting saturated animal fats with healthier fats like olive oil, canola oil, peanut oil, and avocados results in a drastic reduction in your LDL cholesterol. (2,3) Specifically, a diet high in olive and sunflower oil, that contains 12.9% saturated fat, 15.1% monounsaturated fat, and 7.9% polyunsaturated fat can achieve an 18% reduction in LDL cholesterol vs people on a diet higher in saturated fat. (2)
2Bran (Oat, Rice)
Wheat Stalks
Cholesterol Reduction:7-14%
Bran, particularly oat bran, has been proven effective in lowering LDL cholesterol levels. (4, 5) Add bran to hot cereals and bread. Also, eating whole oatmeal every morning, or switching to whole products like brown rice, can help you get more bran in your diet and lower your cholesterol.

3Flax Seeds
Flax Seeds
Cholesterol Reduction: 8-14%
Up to 50 grams of flax seeds a day has been shown to reduce LDL cholesterol in healthy young adults by up to 8%, (6) and 38 grams of flax seeds per day reduced LDL cholesterol by 14% in people with high cholesterol (hypercholesterolemia). (7) In both studies, the flax seeds were consumed in a muffin or other bread product. Flax seeds are easily incorporated in baked goods, as well as added to hot cereals like oatmeal.

4Garlic
Garlic
Cholesterol Reduction: 9-12%
Studies show that less than half a clove (900mg) of raw garlic a day can lower cholesterol by 9-12%. (8,9) Raw garlic is best and can be added to olive oil salad dressings, or as a garnish on soups and sandwiches.

5Almonds
Almonds
Cholesterol Reduction: 7-10%
Several studies report that eating up to half a cup of almonds can reduce cholesterol levels by up to 10%. (10,11) In a dose-response study, it was found that a quarter cup of almonds reduces cholesterol by 5% and half a cup causes the full 10% reduction. (11) As almonds are a high calorie food,it is not recommended that you eat more than half a cup. Almonds are great as a snack, or as an addition to breakfast cereals like oatmeal.

6Lycopene Foods
Tomatoes
Cholesterol Reduction: 0-17%
Lycopene is a carotenoid pigment responsible for giving fruits and vegetables their red color and is found in tomatoes, watermelon, and various other high lycopene foods. Studies are conflicting as to whether lycopene reduces LDL cholesterol or not. Some studies report a 10-17% reduction (12,13) while other studies find no difference. (14) Despite this difference, lycopene is thought to generally promote heart health whether it lowers LDL cholesterol or not.
7Walnuts and Pistachios
Pistachios
Cholesterol Reduction: 10%
Numerous studies report a reduction in cholesterol with consumption of walnuts or pistachios. (15,16,17) This is especially true when the fats from the nuts replace consumption of other high cholesterol fats. Consuming around 30 grams of walnuts, or having the nuts be about 20-30% of the total caloric intake is necessary to achieve the cholesterol-lowering benefits. (18)

8Whole Barley
Whole Grain Barley
Cholesterol Reduction: 7-10%
Like the bran from oats and rice, barley reduces cholesterol, particularly when it is used as a substitute for wheat products. (19) Barley can easily substitute for wheat in the form of barley noodles, barley flour, or whole pearl barley.

9Dark Chocolate and Plant Sterols
Dark Chocolate
Cholesterol Reduction: 2-5%
The plant sterols and cocoa flavanols in dark non-milk chocolate reduce cholesterol by 2-5%. (20) Further, plant sterols (phytosterols), found in all plants, and particularly plant oils like corn oil and soybean oil have been shown to lower LDL cholesterol by up to 16%. (21) However, this reduction is largely due to inhibiting absorption of cholesterol, and would not have a large effect if you consumed little or no cholesterol.

10Green Tea
Green Tea
Cholesterol Reduction: 2-5%
Green tea has long been a staple in East Asia where it is believed to wash oil (fat) out of the body. Studies suggest this may be true as green tea can lower cholesterol by 2-5%. (22) Green tea without sugar also has few calories (typically less than 10) and can make a great substitute for a variety of beverages.

More Lifestyle Choices to Lower Cholesterol

  • Take Niacin (Vitamin B3) Supplements - Niacin has been shown to lower LDL (bad) cholesterol and raise the level of HDL (good) cholesterol. (23) The degree to which it lowers LDL cholesterol has not been measured, but one study reports a 20% increase in HDL (good) cholesterol. (24) There are no studies on the effect of high niacin foods as compared to the supplement. However, it is commonly construed that eating high niacin foods will help lower bad LDL levels while raising good HDL levels.
  • Exercise - Studies suggest that regular aerobic exercise (walking, swimming, running) can increase levels of good (HDL) cholesterol. High HDL cholesterol protects your cardiovascular system. Exercise especially helps people with low levels of HDL cholesterol. (25,26) Further, exercise can enhance the effect of a low cholesterol diet, lowering levels of bad (LDL) cholesterol. (27)
  • Lose Weight - Losing weight, particularly belly fat, will help lower LDL cholesterol levels, and will certainly help prevent type II diabetes, a big risk factor for cardiovascular disease. (28,29) Check your Body Mass Index (BMI) and aim for a BMI between 20-22.
  • Become Vegan - Being vegan involves eating only plant foods and avoiding all animal foods such as dairy, meats, seafoods, etc...Veganism has been shown to lower cholesterol numbers as well as triglyceride levels. (30) This is especially true for vegan diets that do not contain refined sugars, processed foods, or trans-fats, and consist mostly of high fiber foods like beans, nuts, whole grains, fruits, and vegetables.
  • Reduce Stress - Studies show that mental, emotional, or psychological stress can increase cholesterol levels by 10%.(30,31,32) One study, in particular, found that college students have high cholesterol levels before tests than other times in the semester. (32) Another study found that performing a stressful mental activity, like math, increases cholesterol levels. (33) To reduce stress in your life try drinking hot tea, yoga, or spending time with friends. Try new things till you find something that works for you.
