The food suitable for the elderly will be soft, semi-liquid or semi-solid food, such as porridge, noodle soup, paste-like food. Because the teeth and chewing function of the elderly are relatively reduced, too hard food will increase the burden of chewing and is not conducive to the digestion of the gastrointestinal tract. In terms of the type of food, in the prevention of sarcopenia in the elderly, it is important to increase protein-rich foods such as eggs, milk, lean meat and beans, which are very helpful in preventing muscle decay in the elderly. Older people are also prone to osteoporosis and are suitable to eat calcium-rich beans and soy products, dairy and milk products. The elderly should have a balanced diet and a variety of foods. Suitable foods are soft, easy to digest, rich in protein and calcium, which may be more suitable for the elderly.
