Seven, according to the attributes of food, reasonable arrangements for three meals have different attributes, some are hot dishes in summer, and some are cold dishes; Food also has different natural properties: warmth, cold and peace. People with different constitutions should choose foods that suit their constitutions. For example, people with excessive internal heat choose flat or cool food dishes to make home-cooked dishes, while people with deficiency of spleen and stomach choose warm or flat food. Plain food is suitable for all kinds of summer dishes. Summer dishes can be eaten regardless of physical condition. The food for three meals a day should not be completely hot or cold. We should pay attention to the reasonable collocation of summer dishes and keep the balance of food attributes. If the food you eat is hot, you can eat cold or flat fruit. In addition to the nature of food, different cooking methods and cooking materials will also change the nature of food to varying degrees. If you use recipes such as stewing, roasting, stewing, frying, burning and stewing, cold food can become warm; Choosing pictures of seasoning dishes such as onion, ginger, garlic, cinnamon, pepper and cooking wine can also change the nature of cold food. We should allocate different attributes of food, delicious dishes, dishes, pictures, dishes and dishes flexibly and dynamically according to our actual physical condition, and choose reasonable cooking methods. For example, braised eggplant with garlic, so that the nature of the dish will not be too cold; Red hot pot summer dishes, home cooking, you can choose cool celery, spinach, mushrooms, river fish slices and other dishes to make, in order to maintain the balance of delicious dishes in home cooking, to overcome the negative impact of diet on health. Generally speaking, in cooking, we should choose flat and cold food as the main home-cooked and delicious dishes in summer, but the opposite is true in winter. Judging the attributes of seasonal vegetables is very simple, that is, vegetables planted in summer are generally cold, while summer dishes and recipes are hot in winter, and so are fruits; Some vegetables and delicious dishes planted in greenhouses are home-cooked, and the seasonality is no longer obvious, but their food attributes are basically preserved. However, this seasonal principle is generally home cooking. Although the pictures of home cooking are winter dishes and Natsuna, the recipes are very hot for a week, which is harmful to health. A better way is to properly adjust the arrangement of breakfast, lunch, dinner or recipes in a week, so that the food properties tend to be balanced, and it is easy to implement the principle of food diversification.
