Extended data:
Dietary balance refers to the ideal diet of human beings, and it is also an important long-term goal of nutrition science. Except that babies from birth to six months can get a balanced diet through breastfeeding, it can be said that no single food can be called a balanced diet for human beings, and only a variety of foods can be matched with each other to form a balanced diet in real life. Theoretically, people's diet is required to satisfy both physiological appetite and physical and psychological material needs, so it is a balanced diet. With the development of nutrition science, the connotation of balanced diet is constantly enriched and developed.
