The blind adherence of the elderly to vegetarian diet may not achieve the effect of health preservation, but may also affect their health.

As the elderly get older, although the energy demand of the body has decreased, the demand for certain nutrients has increased. If you are a blind vegetarian, and you don't pay attention to finding ways to get protein from vegetarian food, your resistance will decrease and you will be prone to other diseases.

The food for the elderly should be diversified. The daily diet should be rich and varied, remember that the variety is single and ensure a balanced nutrition.

It is suggested to choose milk and egg foods, which are easy to meet nutritional needs and beneficial to health.
