Ground floor: Whole grains are the staple food of China people. In addition to white rice and refined flour, coarse grains should be added. Because the minerals in millet, oats and sorghum are rich in nutrients, they can't be synthesized in the human body and can only be absorbed from the outside.
Second floor: vegetables and fruits-vegetables are divided into roots, stems, leaves, flowers, melons and fruits. All kinds of vegetables have different nutritional components, especially dark green and orange vegetables and fruits, which are high in nutritional components, so pay attention to them when catering.
Layer 3: Chicken, duck, fish, meat and eggs-all protein foods, and different people should eat them in proportion. Don't eat duck when eating chicken, but eat more fish when eating pork.
Layer 4: Milk and bean products-these foods are rich in calcium, which is the most lacking nutrient for China people. If conditions permit, everyone should drink a bottle of milk every day. If conditions permit, you can drink soy milk or eat soy products.
The fifth layer: condiments-three white foods, namely lard, salt and sugar, should be eaten less.
