The human body is designed for self-healing so long as it is in balance and has the proper nutrients to put to work.
Proper nutrition is necessary for sufficient energy, to stabilize blood sugars, balance moods, for lovely hair and skin, to ward off the negative symptoms associated with aging, and prevent disease.
There are basic nutritional laws that work for everyone, but because every body's not the same, there are considerations that need to be made for specific conditions and body chemistry.
