Chinese medicine defines the natures of foods as hot, cold, warm, cool, wet and neutral. It is the same definition as our body constitution.
All foods can be defined as Hot (Yang) or cold (Yin) or having varying other qualities similar to our body types such as damp & just to confuse things, certain types of food can also be neutral
Knowing your body’s constitution and the nature of foods are necessary to eat right for your type. When the body is in balance, it is in good health and is more resistance to disease and external evils.
You are born with a specific body constitution determined by genes and the diet of your mother when carrying you. However, your diet can change its constitution after birth. Eating foods that are in contrast to your body’s constitution is beneficial because it balances out the effects. This is why people of cold constitution can eat a lot of heat excess foods without getting sick and vice versa. So, what is good food for others can be bad food for you. You just have to eat according to your constitution.
The nature of food can also affect your moods. Too much hot or yang food brings about over excitement. Too much cold or yin food brings about sadness and fearfulness. Foods that are neutral in nature are good for everyone and they promote clear thinking and reasoning.
