Trained not only in human health, but in animal health as well, Dr. Joel Wallach has observed natural practices in the agricultural industry that eliminated diseases in animals (that still plague humans) and doubled animal lifespans. In the first half, he discussed the human body's innate ability to heal itself through natural means, without the use of dangerous and expensive pharmaceuticals. Wallach believes that "The medical system has failed us terribly" and says that diseases such as cystic fibrosis are not genetically based, but are caused by deficiencies in the diet. He said that when he pointed this out as a physician many years ago, he was fired from his job. Randal called in from Indiana to testify that he was cured of diabetes using Wallach’s advice.

Wallach claimed that there are "900 different diseases that are caused by malnutrition" and that by watching your diet, most if not all of these ailments can be controlled or cured. Sam in California asked what kinds of oils were healthy. Wallach said that no oils are OK for consumption, because they turn into trans fats and other unhealthy compounds and increase the risk for cancer. Michael in Virginia asked how the issues that were discussed on the program could be brought "to all Americans." The answer, Wallach said was to realize that the health care system in the United States is essentially "unconsitutional and un-American." He believes that everyone should have the chance and resources to diagnose their own diseases.
