Traditional Chinese doctors believe we need a balance of yin and yang to be healthy. For example, are you often weak and tired? Maybe you have too much yin. You should eat hot yang food, like beef. Eating Dangshen and Huangqi berbs is also good for you. But people who are too stressed out and angry may have too much yang. Chinese doctors believe that they should eat more yin food like tofu. Chinese medicine is now popular in many western countries. It's easy to have a healthy lifestyle, and it's important to have a balanced diet.
