Recently, the American Heart Association issued a 'chairman's suggestion' to say that replacing foods rich in saturated fatty acids with foods rich in unsaturated fatty acids can reduce cardiovascular disease by 30%. The prevention of cardiovascular disease is comparable to statin drugs. For example, using avocado instead of steak and using rapeseed oil instead of butter can help maintain heart health.
Zhang Qian, a professor of cardiology at Fuwai Hospital, Chinese Academy of Medical Sciences, explained that the above two fatty acids belong to lipids and play an important role in human metabolism. Saturated fatty acids are more common in fats of cattle, sheep, pigs and other animals; Fatty acids are essential fatty acids that make up human body fat, linoleic acid, linolenic acid, arachidonic acid and other polyunsaturated fatty acids. The body cannot synthesize and must be supplemented by dietary supplements.
Animal fats are rich in saturated fatty acids and also contain a lot of cholesterol. Excessive intake may lead to elevated blood cholesterol, especially low-density lipoprotein cholesterol. In contrast, unsaturated fatty acids can be promoted in the human body. Lipid metabolism, lowers LDL cholesterol and triglycerides in the blood, and improves the high-density lipoprotein cholesterol content beneficial to the human body. Unsaturated fatty acids maintain normal blood lipid levels in the body, maintain lipid metabolism balance, and prevent heart failure. Vascular disease, improving endocrine, etc. all play a key role.
In daily life, lard, butter and other animal oils and nut products such as peanuts, walnuts, sesame seeds, contain large amounts of saturated fatty acids; egg yolk and animal organs such as liver, brain, kidney, etc., contain saturated fatty acids and cholesterol, excessive consumption Causes hypercholesterolemia and abnormal lipid metabolism; Deep-fried, barbecued foods have high levels of saturated fatty acids. These are important risk factors for atherosclerosis. Unsaturated fatty acids are found in vegetables, fruits, fish and milk. In the category, as well as vegetable oils such as soybean oil, rapeseed oil, and sunflower oil. Therefore, it is recommended to replace some animal oils with vegetable oils in the diet, which is more conducive to health.
Prof. Zhang Ji reminded that patients with hyperlipidemia, arteriosclerosis and other diseases, and healthy diet can not take the place of medical treatment. They can improve their lifestyle while taking medications, adopt healthy recipes, control their diets, and regulate their daily routines. Oxygen exercise, so that the effect will be better.
