George Noory welcomed Dr. Joel Wallach, who discussed the human body's innate ability to heal itself through natural means and various minerals and supplements. Many diseases and ailments are the result of dietary deficiencies, particularly minerals and rare earth minerals, rather than genetic causes, he argued. In February 2015, the Journal of the American College of Nutrition wrote that 40% of Americans are deficient in four minerals and three vitamins, and to flourish (rather than just survive) people need as much as 2500 times the minimum daily requirement of many nutrients, he reported.

The environment of a person's stomach is important in terms of how nutrients are absorbed, and people will react quicker to supplement treatments, when they have good absorption, he explained. Cancer, he remarked, is not genetic and can be related to dietary causes such as cooking meat well-done, and consuming oxidized oils in such foods as salad dressings and rancid nut butters. The pharmaceutical industry, he added, is only designed to treat symptoms over a long period of time (except for antibiotics). "There's no money in the cure, so doctors always treat people for 25 years rather than cure them in three weeks," Wallach declared.
