The "hard" eating here actually doesn't mean something with hard taste, but refers to food with rich nutrition and high energy. Liu Dequan said that a good breakfast can better ensure the energy needed for a day's activities. Such as lean meat and cereal. However, the elderly with weak digestive function should also consider whether the food is digestible.

After dinner, people's activities will be reduced. In order to avoid food accumulation, eat less, choose digested food, porridge is better, and meat and spicy food are best avoided. Eating porridge for dinner also has the effect of nourishing the stomach and calming the nerves. It is suggested that the elderly can eat some yam porridge, lotus seed porridge, jujube porridge and so on.
