After the long summer, the weather is getting hotter and the diet should be light. Give priority to foods that are easy to digest and rich in vitamins, and eat less big fish and meat and greasy and spicy foods. After the long summer, the dietary principle is "nourishing yang in spring and summer", and nourishing yang focuses on nourishing the heart, which can not only supplement nutrition, but also strengthen the heart.

Eating more vegetables, fruits and coarse grains at ordinary times can increase the supply of cellulose, vitamins B and C and prevent arteriosclerosis. In short, in the long summer season, it is necessary to nourish the heart and nature, make good preparations for summer heat, and make the functions of various organs of the body normal, so as to achieve the state of "sufficient healthy qi and no evil".

The custom of "eating eggs in the long summer" has a long history. As the saying goes, "if you eat eggs in the long summer, it will not be summer when it is hot." According to legend, since the day of long summer, the weather has been sunny and warm, and it has gradually become hot. Many people, especially children, will feel tired, lose their appetite and gradually lose weight. This is the so-called "squat".

Nu Wa Niangniang told the people that every year during the Long Summer Festival, children hang cooked chicken, duck and goose eggs on their chests to escape the heat. Therefore, the custom of eating eggs in the long summer has continued to this day.

Eating thin food is an important way to keep fit in summer. It is said that cooking long summer porridge is carried out in the corner of the village. Dig a pit on the spot, install a large iron pot, light the porridge and let the smoke curl up. The person who manages this porridge is definitely a kind-hearted grandmother with high prestige among the masses. It is said that after eating this kind of porridge, the neighborhood is harmonious, and I am bent on going to Xia Geng for summer sowing.

Eating porridge in the morning and evening and soup at lunch can not only promote fluid production to quench thirst, reduce temperature and reduce fever, but also nourish the body, which is conducive to regulating the balance of yin and yang in the body. In addition, duck, shrimp, crucian carp, lean meat, edible fungi (mushrooms, Pleurotus ostreatus, tremella, etc. ) and coix seed also have the functions of stimulating appetite, supplementing nutrition, relieving summer heat and keeping fit.
