There is no harm, only good. The nutrients that the human body needs every day are sweet, sour, bitter, salty and colorful. Fat is the weakness of the spleen and stomach. Do not drink cold food in summer, and do not eat hot food in winter. You eat millet gruel every day, eat less sweets, sit for half an hour after meals, go long-distance running, or jump rope 3000 times, and you will also reduce without moxibustion.
