Introduction: The body's blood vessels are like drainage pipes; over time, they can easily accumulate waste, so they should be cleaned periodically. Let's take a look at what these are.
1. Beans. Various beans such as red beans, white beans, black beans, chickpeas, and lentils are excellent food sources of soluble fiber. Fiber can bind with bile salts that carry cholesterol in the small intestine, promoting the excretion of cholesterol from the body. In this process, the liver must consume more cholesterol to produce more bile salts, thereby lowering LDL (low-density lipoprotein) cholesterol levels. Studies have shown that eating half a cup of cooked beans daily can lower LDL by an average of 8%. Chickpeas are the most effective in lowering LDL levels.
2. Apples. Apples are also an excellent source of soluble fiber that can lower LDL, primarily pectin. Studies have also shown that eating an apple a day can slow down the oxidation process of LDL. The key players are the polyphenol antioxidants from apple peels. Since LDL interacts with free radicals to accelerate oxidation, increasing the risk of inflammation, arterial plaque buildup, and thrombosis, it is crucial to consume antioxidants. Additionally, regular apple consumption can improve the liver's detoxification ability and lower cholesterol and blood lipid levels.

3. Nuts and Plant Seeds. Nuts and plant seeds like walnuts, almonds, pistachios, pumpkin seeds, and flaxseeds are excellent sources of heart-healthy monounsaturated and polyunsaturated fats, vitamins, trace elements, and fiber. Research has found that replacing saturated fats in the diet with nuts and plant seeds can effectively lower LDL and total cholesterol levels without affecting "good" cholesterol (HDL) levels. Since nuts and seeds are high in calories, daily intake should be limited to 1 ounce (about 28 grams). It is also best to avoid salted or sugar-coated nuts.
4. Green Tea. Antioxidant-rich teas like green tea, black tea, oolong tea, and white tea all help lower LDL, with green tea being the most effective. The reason is that green tea is made by drying tea leaves directly, so its powerful antioxidants are not oxidized during fermentation. Studies have found that regular consumption of green tea can lower LDL levels by about 2%. Green tea can also prevent rupture and bleeding of the capillary walls. Experts suggest drinking several cups of green tea daily to help lower lipids.
5. Oats. Oats and oat bran contain the water-soluble fiber beta-glucan, which helps lower LDL levels. Multiple studies have shown that consuming at least 3 grams of oat beta-glucan daily can lower LDL by an average of 7%. Research has also found that the polyphenol antioxidant avenanthramide in oats helps fight inflammation, prevent thrombosis, and inhibit atherosclerosis.

6. Red Grapefruit. A study found that eating one red grapefruit daily for a month can lower LDL levels by 20%. This may be related to the limonin and lycopene in red grapefruit. Grapefruit is also rich in soluble fiber pectin, which also helps lower LDL. Expert reminder: Grapefruit can enhance the effects of heart medications such as statins and calcium channel blockers. Therefore, patients taking such medications should consult their doctor before eating grapefruit.
7. Red Wine or Grapes. Research has found that the plant compound resveratrol in the grapes used to make red wine can lower LDL levels. This substance has antioxidant and anti-inflammatory properties and can also prevent coronary heart disease. Additionally, a glass of red wine daily can prevent vasoconstriction after a high-fat diet, thereby reducing the risk of atherosclerosis and heart attack. For non-drinkers, resveratrol can be obtained from grapes, blueberries, cranberries, or peanut butter. For drinkers, limit red wine to no more than 1 to 2 glasses per day, each 5 ounces (about 142 grams).
8. Plant Sterols. Plant sterols are natural substances found in small amounts in vegetable oils (like corn and soybean oil), nuts, beans, whole grains, fruits, and vegetables. Studies have shown that consuming 2 grams of sterols daily for 4 weeks can lower LDL levels by 6% to 14%. The mechanism is that plant sterols can inhibit the absorption of cholesterol in the small intestine, thus helping to lower LDL. Although it is difficult to get 2 grams of sterols directly from fresh foods, one can choose some sterol-fortified foods.
