In harmful summer, cold foods such as iced watermelon, iced milk and iced beer enter the stomach, which makes the blood vessels in the stomach contract, the temperature drop and the bacterial reproduction accelerate. At the same time, because they are not easy to digest, it increases the burden on the stomach and further leads to the decline of spleen and stomach function. When people eat too much cold food or drink, the body needs to wrap them with more yang to raise their temperature before being digested and absorbed. After a long time, the body's immunity will inevitably decline.
China people's spleen and stomach are "hot food genes", which are more suitable for warm food. Long-term gluttony of cold drinks and iced food will damage the spleen and stomach, resulting in spleen and stomach deficiency and cold. In addition, food refrigeration can't kill bacteria, which often causes gastroenteritis.
