Joel Fuhrman said this quote
“ Health is normal. The human body is a self-repairing, self-defending, self-healing marvel. Disease is relatively difficult to induce, considering the body's powerful immune system. However, this complicated and delicate machinery can be damaged if fed the wrong fuel during the formative years. ... Healthy living with nutritional excellence throughout life can slow the decline of aging. It can prevent the years and years of suffering in ill health that is so common today as people get older and become dependent on medical treatments, drugs, and surgery. Nutritional excellence is the only real fountain of youth. ”
