Standing in front of the buffet bar, I don't know how to start with a dazzling array of food. In fact, as long as you master the ratio of staple food, non-staple food and main course of 3: 2: 1, you can take in different nutrients in a balanced way. Hisao Nagayama, a Japanese healthy diet researcher, put forward five simple balanced diet methods in 120 healthiest foods in the refrigerator, so that ordinary people can stay healthy and stay away from diseases by eating lightly. 1. The ratio of staple food to non-staple food is 3: 2: 1. The key to a balanced diet is to keep the portions of various foods balanced. The standard ratio of staple food, side dishes and main courses is 3: 2: 1. According to this ratio, the staple food is usually 1 bowl of white rice; The side dish is 2/3 bowls of stewed cabbage or scalded vegetables; The main course is 1 bowl of thin slices of meat or fish. Second, the use of different ingredients is balanced. Some people often make many dishes from the same ingredient when cooking, just like a potato made of fried potatoes, potato stew and mashed potatoes. Although this saves time, it is also easy to cause nutritional imbalance. Need a variety of ingredients to bring all aspects of nutrition. Third, the same category 1 copy is just right. Is it your heart to kill pork chops and fish chops? In fact, the main course and staple food only need 1 course to meet the nutritional needs of a meal. For example, the combination of two or more staple foods, such as fried noodles and rice moss, is easy to cause nutritional imbalance. Fourth, less oil is healthier. Try to limit each meal to only 1 dish cooking with oil, and reduce the intake of oil, so that calories will not be eaten with nutrition. Too simple conditioning methods, such as frying or baking, will consume too much salt and oil at once, and the taste of food will be too similar, which will also reduce appetite.
