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. For the problem of gout (an inflammatory condition associated with the presence of uric acid), he recommends avoiding such foods as organ meats, shellfish, and beans which are high in uric acid. Gout can affect the nervous system, he added, and topically applied CBD oil can temporarily reduce pain from the condition.

In cases of optic nerve atrophy where vision starts to decrease, he said that doctors sometimes misdiagnose the problem as related to cataracts, a detached retina, or glaucoma, but treatment for these generally doesn't work because "you have osteoporosis of the skull squeezing the...optic nerve." Various supplements like lutein can help repair the eye, Wallach cited. He also suggested that the problem of obesity is less connected to overeating and lack of exercise and mainly brought about by nutrient deficiencies.
