Dr. Joel Wallach addressed alternative health approaches and the benefits of remedies and supplements that aid in the body's recovery from many diseases and ailments. When an appendix has to be surgically removed, he suggested it's because of an advanced infection that is due to gluten intolerance. He also cited a 1992 study which indicated that many medical doctors in surgical suites and emergency rooms were intoxicated while on duty, and he advocated that drug and alcohol testing be a regular requirement before they start their shifts.

When it comes to autoimmune diseases, he recommended starting with dietary changes, eliminating fried foods, processed meats, oils, gluten, wheat, and oats. Cramps are related to mineral deficiencies, he continued, and the supplements he advised for this include MSM and Vitamin D3. Dr. Wallach believes that cases of depression and other types of mental illness (such as exhibited by school shooters) are due to a deficiency of the mineral lithium, which hair testing can reveal.
