Dr. Joel Wallach discussed the human body and its ability to achieve healing from chronic conditions through natural remedies and supplements. Criticizing conventional medicine's approach to ailments like arthritis, he said that many conditions can be improved through nutrition and lifestyle changes. He emphasized the need to avoid fried food, processed meat, oil, gluten, and sugar to prevent diseases, as well as carbonated drinks which can interfere with the digestive process. Dr. Wallach also addressed concerns about muscular dystrophy in a caller's family, asserting that many neurological diseases could be prevented and even reversed with proper nutrition. He reiterated, "If you're not getting the nutrients in your diet, or if you're eating stuff that interferes with the absorption of nutrients, like gluten, you're in trouble."

According to Wallach, there is an alarming connection between diet and cancer, particularly prostate and liver cancers. He cited the dangers of peanuts, claiming they are often contaminated with a harmful fungus, Aspergillus flavus, which produces a toxin called aflatoxin that can lead to cancer. "You can't taste or smell it," he added. A caller, John, shared his experience with celiac disease, an auto-immune disorder, and how eliminating gluten significantly improved his health.
