This is completely wrong. After entering old age, the muscles in the body gradually decrease and the proportion of fat gradually increases.
This is a typical "muscular dystrophy" among the elderly.
The sequela of muscle loss is to affect the stability of joints. Further development will lead to osteoarthritis, joint degeneration, hyperosteogeny and other diseases. Muscle loss can also make the body weak, unstable in walking, low in immunity, lower in metabolism, and increase the risk of chronic diseases.
An important measure to prevent muscular dystrophy is to supplement enough protein in the diet. It is found that protein contained in various meats and protein (whey protein) contained in milk are particularly effective in delaying muscle attenuation, probably because protein in these two foods can provide more "leucine", which is just an amino acid needed for muscle metabolism. Therefore, high-protein foods such as fish, meat, eggs and milk cannot be lacking in the diet of the elderly. Only with enough high-quality protein as the support, can we slow down the muscle attenuation of the elderly, thus reducing the occurrence of various diseases of the elderly.
Besides providing high-quality protein, meat is the best source of iron.
Iron deficiency anemia is also one of the most common nutritional deficiencies in the elderly, which will make the elderly weak, immunocompromised and more aging. Supplementing more meat is helpful to prevent the occurrence of iron deficiency anemia in the elderly.
Therefore, it is wrong to emphasize that the diet of the elderly is weak. On the contrary, protein should be included in the recipes of every meal for the elderly, and eggs, milk, meat, fish, shrimp and bean products should be evenly distributed in three meals, which is very beneficial to the health of the elderly.
It should be reminded that in order to avoid excessive intake of saturated fat and cholesterol, we should choose lean pork, lean beef, lean sheep, chicken (without skin), most fish and seafood and other foods that are beneficial to the health of the elderly, while pork belly, fat ribs, fat beef and chicken skin should be eaten less or not. Why is it wrong for the elderly to eat less meat, eggs and milk? Because of the lack of protein! Many people think that with the growth of age, the functions of the body are declining, and the ability of digestion and absorption is also declining, so the diet of the elderly should be light, less oil and less meat. In fact, this is all wet. protein is particularly important for the elderly.
Protein is the most important nutrient for human body, and it is almost absent. It can be said that there would be no life without protein. According to the recommendation of China Nutrition Society 20 13DRIs, the recommended daily intake of protein for people over 50 years old is 65g for men and 55g for women. In other words, compared with young adults, there is no decrease.
Protein deficiency, for the elderly, the most common problem is muscle attenuation syndrome. After the age of 50, the muscle mass decreases by 1% to 2% every year. If the muscle mass decreases by more than 30%, the normal function of the muscle will be affected. In the case of serious muscle loss, it will affect the stability of joints and the balance of the body. There are a series of problems such as falling easily when walking and choking easily when eating. Seriously, it will even develop into weakness and life can't take care of itself.
Protein in diet, especially high-quality protein, is not only the raw material of muscle protein, but also the promoter of muscle protein synthesis. However, the dietary protein of 0.8 g/kg body weight per day is not enough to maintain the skeletal muscle quality of the elderly. More than 0.8 g/kg is helpful to promote protein synthesis in the elderly, and reduce skeletal muscle protein and age-related loss. If the renal function of the elderly allows, it should reach 1.0 ~ 1.3g/kg body weight. A little more than ordinary young adults.
The main sources of high-quality protein are meat, eggs and milk. Therefore, the diet of the elderly must not be too light, and meat, eggs and milk must be sufficient.
