Traditional Chinese medicine believes that spring is the season when yang is born, so people should adapt to the change of weather and keep healthy through diet. The general principle of diet regimen is: 1. Choose high-calorie foods among staple foods; 2. Ensure sufficient quality protein; 3. Ensure adequate vitamins. The so-called high-calorie food refers to the high-calorie food such as beans and peanuts except rice, flour and miscellaneous grains in the staple food. The so-called high-quality protein refers to milk, eggs, fish, poultry, pigs, cattle, sheep and lean meat. Vegetables and fruits have high vitamin content, such as tomatoes and green peppers, which contain more vitamin C, and are important substances to enhance physical fitness and resist diseases. Dietary aftercare in spring can be divided into three periods. Early spring, winter and spring alternate, the temperature is still cold, and the human body consumes more calories, which is suitable for eating warm food. The principle of diet is to choose staple food with high calorie, and pay attention to supplement enough protein. In addition to miscellaneous grains, beans, peanuts and dairy products can also be added to the diet. For example, breakfast: milk 1 bag (about 250ml), staple food100g, and appropriate side dishes. Lunch: staple food 150g, lean pork, beef and mutton (or bean products) 50g, green vegetables 200g, and egg soup or broth. Dinner: staple food 100g, egg fish (or bean products) 50g, green vegetables 200g, bean porridge 1 bowl. In the middle of spring, the weather changes greatly, and the temperature changes suddenly, which can be carried out with reference to the diet in early spring. When the temperature is high, you can increase the consumption of vegetables and reduce the consumption of meat. In late spring, at the turn of spring and summer, the temperature is hot and it is suitable for eating light food. The principle of the Diet Health Forum is to choose light food and pay attention to supplement enough vitamins, such as adding vegetables to the diet. For example, breakfast: 250 ml of soybean milk, staple food 100 g, and appropriate side dishes. Lunch: staple food 150g, fish, eggs, meat (or bean products) 50g, vegetables 250g, and vegetable soup. Dinner: staple food 100g, green vegetables 200g, rice porridge 1 bowl. In addition to three meals a day, eat more fruits, because the vitamins and minerals contained in fruits are conducive to strengthening physical fitness. Avoid eating cold and greasy food in spring. Traditional medicine also believes that eating more sour food will lead to excessive liver qi and damage the spleen and stomach, so eat less sour food.
