Eat more vegetables. After winter, most people will have insufficient intake of vitamins, inorganic salts and trace elements, such as stomatitis, angular stomatitis, glossitis, night blindness and some skin diseases in spring, all of which are due to the nutritional imbalance caused by eating less fresh vegetables. Therefore, with the arrival of spring, a large number of fresh vegetables are on the market, so people must eat more fresh vegetables, such as spinach, mustard, lettuce, celery, rape, Toona sinensis and so on. If there are few fresh vegetables in early spring, you can make full use of refrigeration to dry.
