Neutral food: grain.
Negative food: fruit, cauliflower, mung bean, coix seed, candy, processed food, uncooked raw food.
The yin and yang properties of food are variable.
Food is also divided into yin and yang. People with yin syndrome use warm positive food, and people with yang syndrome use cold negative food, thus regulating the excess of yin and yang in human body.
The yin and yang properties of food will change under different conditions, which is an important feature. For example, foods with a lot of water, such as sashimi and wild vegetables, can clear away heat, so they are yin, but when cooked and heated, they become yang.
The attribute of cooked food is yang, but compared with raw food, if compared with other cooked food, it still has yin and yang, that is, it does not necessarily belong to yang.
Animal food is dynamic and static compared with plant food, which is yang. Compared with animal food, there are yin and yang differences, and compared with plant food, there are also yin and yang differences.
In other words, the yin and yang of food are relative rather than absolute.
Therefore, in the actual menu, if the eater's syndrome belongs to the Yin syndrome series, the main course should be Yang species in meat food, and the side dishes should be warm wild vegetables belonging to Yang in plant food, so as to increase the intensity of warming Yang by various means (the opposite is true for patients with Yang syndrome series).
