Teach you to save the "capital" of life! The important role of fat should be known early.

Memory loss, decreased resistance and loose skin are all caused by vegetarianism? Eating too many snacks and fried foods can cause cardiovascular disease? Even cause coronary heart disease? Let's listen to the expert's interpretation-how to "save money" for life through healthy eating! Shi Shi, deputy director of nutritionist, the price of longevity in clinical nutrition department of China Rehabilitation Research Center-fat is the "price" of longevity, an important part of human body, an energy storage substance and one of the important nutrients in human body. Scientifically matching the types of fat can not only prevent the occurrence of chronic diseases and strengthen the functional role of fat, but also supplement some essential amino acids that the human body cannot synthesize. Fat has many functions. For old friends, these three are the most important. Delaying brain aging and enhancing memory fat is an essential nutrient for the brain. In the human brain, lipids and unsaturated fatty acids account for more than 50% and 10% respectively. Lipids can help the brain maintain good function, delay aging and enhance memory. Visceral "shock absorber" adipose tissue is particularly soft and wrapped around important organs, which can prevent friction between important organs and reduce damage; Fat also has a buffering effect, which can protect human organs from being damaged during exercise. Fat used to delay skin aging can form a sebum layer on the skin surface, which can lubricate the skin, resist external bacterial erosion and prevent infection. Without fat, the skin will become loose and thin. Tips The intake of unsaturated fatty acids can increase skin moisture and enhance skin elasticity. How to choose foods containing fat? Older people over 65 who choose oil scientifically are advised to take peanut oil, rapeseed oil and olive oil. The recommended daily intake of edible oil is 25-30g. The types of fatty acids determine the characteristics and physiological functions of oils and fats. Fatty acids include three kinds: saturated fatty acids, polyunsaturated fatty acids and monounsaturated fatty acids. Tips Monounsaturated fatty acids Monounsaturated fatty acids can reduce triglycerides and cholesterol and prevent arteriosclerosis. Peanut oil Peanut oil contains a relatively balanced proportion of unsaturated fatty acids, and linoleic acid in peanut oil can combine with cholesterol to help regulate blood lipids. The contents of saturated fatty acids and polyunsaturated fatty acids in tea seed oil and olive oil tea seed oil are low, and the proportion of monounsaturated fatty acids is high. The fatty acid ratio of olive oil is similar to that of rapeseed oil, but it is cost-effective. The content of saturated fatty acids in lard is high, so eating more lard can easily lead to "three highs", leading to increased blood lipid and atherosclerosis. How to choose meat? Supplementing fat suggests that the elderly should eat more tenderloin for red meat and sea fish for white meat. Red meat: tenderloin The daily intake of red meat for the elderly should be controlled at 50 ~ 75g. Pork belly and ribs are high in fat, so it is not recommended as a source of fat intake for the elderly. Pork tenderloin, as a kind of red meat with low fat content, is suitable for moderate fat supplementation. Marine fish such as leucorrhea and wild salmon are rich in omega-3 fatty acids, which are suitable for supplementing human fat. Note: Hairtail has high omega-3 fatty acid content, less fat, less thorns and delicious taste, which is more suitable for the elderly. How to choose snacks? Shortened oil of snacks contains a lot of trans fatty acids, which is harmful to health. Snacks can't help save lives. Excessive intake of trans fatty acids will increase the risk of coronary heart disease. Trans fatty acids and saturated fatty acids have the risk of cardiovascular diseases, especially coronary heart disease. Repeated use of fried snack oil or high temperature will do harm to human health. At high temperature, fatty acids rich in oil react to produce toxic substances such as cyclic monomers, dimers, trimers and heterocyclic amines, which will endanger people's health. Nuts are high in unsaturated fatty acids, which can regulate blood lipids and lower cholesterol. Phytosterols contained in nuts can inhibit the absorption of cholesterol and reduce the risk of atherosclerosis. Old people need to eat more with strict control and scientific collocation: healthy oil, tenderloin, sea fish and nuts, and add some fat regularly to save money for life!
