In these pages, we often report on vitamin A—that most necessary of all nutrients, found in very high levels in primitive diets but declared toxic by modern dietary authorities. Vitamin A supports vibrant health in so many ways—from formation and development of the fetus to hormone production to healthy eyes, skin and bones. A new report summarizes research showing that vitamin A supports a preventive, therapeutic and even regenerative role in hearing loss, and can even allay tinnitus—ringing in the ears. For example, a French study from as early as 1823 found that hearing levels were better among those who consumed the most vitamin A and also vitamin B12 from various foods, including red meat. A 1984 European study reported a 5-15 decibel improvement in patients with age-related hearing loss when given vitamins A and E. Other researchers reported that vitamin A deficiency results in a decline in the number of sensory cells in the nose, tongue and inner ear. A 1993 study reported in Science found that vitamin A can stimulate the regeneration of mammalian auditory hair cells. In 2009, Japanese researchers found that adults with the highest blood serum levels of vitamin A and carotenoids have the lowest risk for hearing loss. And, in 2014, researchers determined that vitamin A deficiency during pregnancy, especially during the early stages of fetal development “may predispose offspring to inner ear malformations and sensorial hearing loss.” These studies and several others are detailed in a fascinating report by Bill Sardi at knowledgeofhealth.com, May 21, 2014.
