医生：能降「坏胆固醇」的食物，这3种效果最好

Core Viewpoint - The article emphasizes the importance of managing low-density lipoprotein cholesterol (LDL-C), commonly known as "bad cholesterol," through dietary choices and medication to reduce the risk of cardiovascular diseases [1][2]. Dietary Components to Lower LDL-C - Soluble dietary fiber acts like a sponge in the intestines, binding cholesterol and preventing its absorption, thereby gradually lowering LDL-C levels [5]. - Foods rich in soluble fiber include oats, barley, whole grains, legumes (especially lentils, chickpeas, black beans, and white beans), and certain vegetables like okra and eggplant, as well as fruits such as apples, grapes, strawberries, and citrus fruits [6]. - Unsaturated fatty acids help lower LDL-C levels, while saturated fats tend to raise them [7]. - Foods high in unsaturated fats include nuts (such as almonds, walnuts, and peanuts), plant oils (like canola, sunflower, and safflower oils), and fatty fish [8]. - Plant sterols and stanols compete with cholesterol for absorption in the intestines, leading to reduced cholesterol absorption [9]. - Research indicates that consuming 2 grams of plant sterols/stanols daily can lower LDL-C by approximately 10% [10]. - Foods high in plant sterols include certain plant oils, nuts, whole grains, and legumes, but fortified foods like yogurt, milk, and juice may be necessary to achieve adequate intake [11]. Recommended Foods for Cholesterol Management - Oats are rich in β-glucan, a soluble fiber that reduces cholesterol absorption and synthesis while increasing its excretion. It is recommended to consume 80-100 grams of oat products daily [13][14]. - Soybeans contain proteins that influence cholesterol metabolism and isoflavones that reduce LDL-C oxidation. The suggested intake is about 20 grams of soy or equivalent soy products daily [15]. - Pumpkin is high in dietary fiber that promotes cholesterol excretion and contains plant sterols. The recommendation is to consume 100-200 grams of pumpkin daily, along with a reduction in other carbohydrate sources [16][18]. Lifestyle Recommendations - Regular monitoring of blood lipid levels is crucial, with adults advised to check at least every five years, and high-risk individuals annually [19]. - The updated guidelines suggest that ideal LDL-C levels should be below 2.6 mmol/L for healthy adults, with stricter targets for high-risk groups [20]. - Lifestyle adjustments include increasing physical activity, maintaining a healthy weight (BMI below 25), limiting alcohol intake, quitting smoking, and ensuring adequate sleep [21].
