Food

In my clinical experience food and nutrition aspect are important. Much discussion talks about the danger of consuming gluten and casein product as well as high glycemic index product. To me all this finding align with Traditional Chinese Medicine perspective.
The aim of Chinese medicine is to maintain health through balance on Yin and Yang aspect. Yin and Yang is an ancient philosophy of how Chinese people in that era saw life in relation to universe.
 In this world many things could be divided into two aspects which are opposite each other but also supporting each other and it call Yin and Yang. 

For example:
Yin has the quality of female, solid, cold, below, earth etc.
Yang has the quality of male, ether, hot, above, sky etc.
In human body also consist of these two qualities. Some organs have the nature of Yin and the other is Yang. And illness appears when there is imbalance happen between Yin and Yang. Could be one overpowering the other or the other one is weakness than the other.
Food have this quality as well. And even we can classify some food either Yang in nature or Yin.

For example: Durian is hot or Yang in nature, cucumber is cold in nature or Yin.
In Chinese medicine some food have other qualities that when consumed may stimulates certain organ too much (especially if it’s over consumed).
For example: grilled or fried food, this food is hot and yang in nature, but may stimulates liver and gallbladder too much, which may create imbalance between liver and spleen.
Cow milk is hot and damp in nature, and it may affect spleen in Chinese medicine. In Chinese medicine spleen is also related to the mental function of thinking, so imbalance in the spleen may affect the capability of thinking.
