The diet for the elderly is not the lighter the better
Many elderly people believe that the lighter their diet, the better, and even claim that a vegetarian diet can lead to a longer life. Their reasoning is that vegetarian food reduces the burden on the digestive system, is easy to digest, and can prevent heart disease. However, it is a fact that an overly light diet can weaken one's constitution, making the body more susceptible to illness. Even for the elderly with heart disease, it is not advisable to insist on an excessively light diet.
In a vegetarian diet, apart from legumes which are rich in protein, other foods contain very little protein and have lower nutritional value, making them less easily digested, absorbed, and utilized by the body. On the other hand, non-vegetarian foods such as chicken, duck, fish, and meat can serve as important sources of nutrition, providing the body with large amounts of high-quality protein and essential fatty acids necessary for growth, development, and metabolic processes.
In fact, the main factor for a person's good health is not whether they eat meat or vegetables, but what and how much they eat. This means whether the nutrients the body needs are complete and consumed in appropriate amounts. The components and their quantities ingested from food are precisely what the body needs for its physiological functions and daily activities, which is one of the most fundamental principles of proper nutrition. For example, seafood is generally rich in high-quality protein, contains various unsaturated fatty acids that can lower blood lipids, and vitamins and trace elements that the body often lacks. Consuming more seafood to a certain extent is highly beneficial.
A mixed diet of both meat and vegetables can promote the body's metabolism, ensure the completeness of tissue cell structure, enhance disease resistance, and delay aging while promoting health and longevity. The elderly can base their diet on rice, flour, or coarse grains, and drink soy milk or milk daily. Their meals should consist mainly of lean meat (about 50 grams every 1-2 days), eggs, poultry, fresh fish and shrimp, as well as a variety of vegetables.
