The protein foods would be more building, whereas the fruits would be more cleansing. Grains are rather neutral, so they act as a good base from which to start. Cooking basically adds Qi to your food. Raw foods have reached such acclaim in the United States because the traditional American diet has been so binding and constricting that the raw foods open one up.

Herbs generally come after dietetics, which is a necessary foundation for any herbal work.
With poor dietetics, herbs will not have optimum effect, or only will give temporary relief. One headache or stomach ache is not the same as another headache or stomach ache. It is a big fallacy to believe that because herbs are natural, they are easy to use and can cause no harm. For example, many herbs have cooling or warming qualities. It would generally not be appropriate to give someone who is shivering herbs that would be cooling.
