Old people should eat protein in moderation. For the elderly, quality is more important than quantity in protein. Therefore, it is best to eat half of protein every day with high-quality protein, such as lean meat, milk, eggs, fish, shrimp, beans and so on.

When people reach old age, the function of blood circulation system decreases, and the blood flow speed and blood flow decrease. This requires more hemoglobin in the blood to make up for the decline of this function. Therefore, in addition to adequate intake of protein, we should eat more iron-rich green vegetables, kelp, bean products, sesame sauce and so on.

Old people should eat more foods with high calcium content. Because with the increase of age, the absorption of calcium by the elderly will continue to decrease, and calcium deficiency in the elderly is prone to decalcification and osteoporosis. Therefore, we should pay attention to eating milk, soybean milk, bean curd, shrimp, sparerib soup and other foods, and we can also take a certain amount of vitamin D or cod liver oil to supplement the body's calcium.

The elderly should eat more foods containing multivitamins, such as fresh fruits such as fresh dates, oranges, hawthorn and dermatophytes. Usually eat more fresh vegetables and coarse rice noodles. The diet of the elderly should be light and not too salty. Because the food is too salty, it will increase the content of sodium ions in the body, increase the circulating blood flow and sodium retention, cause vasoconstriction, raise blood pressure and cause cerebrovascular disorders.
