Dr. Joel Wallach discussed the body and its ability to benefit from natural healing without using modern medicine. Diseases and ailments are often related to deficiencies in various nutrients and minerals, he contends. For millennia, humans unknowingly enhanced their diet with minerals by putting wood ashes from fireplaces into their gardens. However, with the advent of electricity, the population largely stopped burning wood, and now have many more health problems because of the lack of these minerals, he stated.

Wallach declared that people can remain in optimal condition by giving the body everything it needs nutrition-wise, as well as avoiding certain dietary items like processed meats, and fried foods. Discussing the condition of gout, he said that it stems from an enzyme/metabolism problem in the liver and suggested that sufferers avoid eating items that make uric acid, including shellfish, legumes (peas/beans), and organ meats.
