Recent studies show that some instances of hearing loss may be a result of a vitamin A deficiency. According to researchers, an inadequate amount of vitamin A in the diet actually leads to an increased sensitivity to sound, which in turn increases the risk of hearing loss from noise damage.
If you experience hearing problems, such as a hearing loss,, good dietary sources, of vitamin A include liver, milk and dairy products, carrots, apricots, cantaloupes, and oranges.
Foods that are rich in biotin, a water-soluble B vitamin, may help put a halt to a receding hairline. Studies show that a biotin deficiency can cause hair loss (as well as dry, flaky skin, and a facial rash). Many hair treatment products feature biotin as an ingredient to help produce healthy hair and prevent graying. The evidence also indicates that hair loss due to an extreme biotin deficiency is reversible with adequate biotin supplementation.
The best dietary sources of biotin include whole grain foods, nuts, organ meats vegetables, and milk. Biotin is also available in supplement form.
