Boost Immunity With Food and Sun.

The article discusses improving the body's immune system through food nutrients and the sun. Vitamin D through sun exposure is reportedly a strong ally against disease, and 200 international units (IU) is the recommended daily intake, with extra amounts that may be needed to be based on the individual's sun exposure and pigmentation. It is stated that white button mushrooms can promote immune function and that people with normal blood zinc concentrations and who consume vitamin E have better immune responses.
