Healing begins at the cellular level and gives vitality to every cell in the body. The type of food ingested affects the health of the cell as well as the organism. The ability to restore cell health allows the body to maximize its potential to downregulate, or turn off, the genes associated with degenerative conditions. Therefore, it is vital to correct nutritional deficiencies at the cell level to maintain or restore optimum health.

Nutritional deficiencies can be corrected by eliminating processed, debilitated foods and replacing them with nutrient-rich foods and whole food supplements, which provides the nourishment the body lacks. A proper diet also balances the endocrine system, which improves and restores the function of the entire body, creating rejuvenation, health, and vitality at the cellular level.
