Dr. Joel Wallach discussed the human body's innate ability to heal itself through natural means and various minerals and supplements. He argued that diseases and ailments are the result of dietary deficiencies, rather than stemming from genetic causes. Among the health topics he addressed was heart arrhythmia, which he associated with degenerative disc disease or vertebrae moving closer together, which then crush against nerves related to the rate and rhythm of the heart. He treats such conditions by suggesting changes in the diet that reduce inflammation, such as not eating fried foods or processed meats, or consuming various oils that turn into trans fatty acids.

If people want to get rid of their addictions, such as tobacco, drugs, and alcohol, he recommended taking mineral supplements whenever they get a craving. "Usually within a week or two, their addiction is gone," he claimed. Wallach also praised the efficacy of herbs such as burdock root, whether in capsules or tinctures. Plant medicines can provide relief from a variety of conditions, such as high blood pressure, diabetes, pain, prostrate problems, PMS, and headaches, he said, adding that herbs have often served as the source for pharmaceutical formulas.
