& ltp> There are dazzling nutriments and health products on the market at present, and the elderly are the key sales targets. At the same time, most of the effective components of health care products can be supplemented by ordinary food, and all kinds of health care products have a certain scope of application, which is not suitable for all the elderly. So, what nutrition do the elderly need to supplement? First of all, the elderly are in a process of aging. Protein in the body is mainly catabolic, and anabolic gradually slows down. Therefore, there are often malnutrition in the elderly, which is characterized by decreased amino acid concentration in blood, decreased hemoglobin synthesis and anemia. Therefore, special attention should be paid to the supply of high-quality protein and iron. But when supplementing protein, we should pay attention to the right amount, generally 60? 80 grams is enough, and the intake of high-quality protein accounts for about 50% of the total. High-quality protein mostly exists in lean meat, eggs, dairy products and bean products. Secondly, the increase of peroxide metabolism in the elderly has become the basis of many diseases. Therefore, we should take more antioxidants in our diet. Such as vitamins a, c, e, selenium, zinc, etc. Enhance the anti-aging, disease-resistant and immune functions of the elderly. Vitamin E is widely distributed in animal and plant tissues, especially good sources are wheat germ oil, peanut oil and sesame oil, and it is also abundant in green leafy plants, meat, eggs and milk. Vitamin C is widely found in vegetables and fruits. Selenium content in sea fish and astragalus is very high, and calcium deficiency in the elderly leads to osteoporosis. Frequent fractures bring great inconvenience to life, so the content of calcium and vitamin D should be increased in the diet to ensure the strength of bones. Most medical experts advise the elderly to drink 1 every day. 2 bags of milk (preferably skim milk), and eat bean products, vegetables and fruits at the same time to get the necessary daily 1000? 1500mg calcium. Moreover, the elderly should ensure 1 hour outdoor activities every day, because sunlight is the best source of vitamin D production.
