Cold food refers to food that does not need to be reheated and can be consumed at room temperature or low temperature. Cold foods should be stored properly, especially those that do not require reheating.

Cold food doesn't necessarily mean cold food, so eating cold food doesn't necessarily mean that it's the right kind of food to reduce fire, for example, some halibut actually causes fire if you eat it. In addition, many fruits also belong to the cold food category, but the high acid fruit is not advisable to eat more, suitable for the summer soak and drink, the effect will be better, such as lemon, prunes, hawthorn and so on.
