　　Why don't you eat the food right away when it's ready?

　　The reason is that 25% of vitamin B1 in vegetables can be lost during the heating process after cooking. If cooked cabbage is heated for 15 minutes, 20% of vitamin C will be lost. If it is kept warm for 30 minutes, another 10% will be lost. If it is kept warm for 1 hour, another 20% will be lost. %, if 20% of the vitamin C in vegetables is lost during cooking, 25% is lost when dissolved in vegetable soup, and another 20% will be lost if heated on fire for 15 minutes, a total of 65%, then there is not much vitamin C left in the vegetables.
