Walnuts have the effect of lowering blood lipid levels. This is mainly due to their rich content of unsaturated fatty acids, especially alpha-linolenic acid, an essential omega-3 polyunsaturated fatty acid. These fatty acids play a positive role in the human body, effectively reducing the concentrations of low-density lipoprotein (LDL, often regarded as "bad" cholesterol) and total cholesterol in the blood, while promoting an increase in high-density lipoprotein (HDL, known as "good" cholesterol).
In addition, walnuts contain abundant dietary fiber and potent antioxidants, which significantly contribute to optimizing lipid metabolism and thereby effectively reducing the risk of cardiovascular disease.
Walnuts also contain a relatively high amount of fat, and excessive consumption may add extra calories, which is unfavorable for weight management and lipid control. Therefore, while enjoying the health benefits of walnuts, it is important to moderate intake.
For patients with high blood lipid levels, in addition to paying attention to diet, it is essential to follow medical advice and adopt appropriate treatment plans.
