"Balanced Diet Pagoda" is the approximate proportion of all kinds of food converted according to the principle of balanced diet, which is expressed in an intuitive pagoda form. "Balanced Diet Pagoda" has more food demand at the bottom, less demand at the top and the least demand at the top. The bottom layer is grain, which mainly provides energy; The second floor mainly provides vitamins for fruits and vegetables; The third floor is animal food, the fourth floor is dairy products and bean products, and the third and fourth floors mainly provide protein; The fifth layer is grease, which mainly provides fat. Therefore, according to the pagoda of balanced diet, we should take in five kinds of food in a balanced way. When arranging meals, we should use diversified foods as much as possible, and properly distribute meals according to different nutritional components in various foods, so as to fully meet the body's demand for various nutrients.
