Zinc deficiency is almost epidemic. While it is an essential mineral needed nearly in all body tissues, more than 68% of adults receive less than two-thirds of the RDA for zinc. Also, vegetarians can need up to 50% more zinc than non-vegetarians due to phytates found in the fiber of most vegetables and grains. Phytates inhibit the absorption of zinc; drinking tea and coffee, and high intakes of calcium, iron and copper can also limit zinc absorption.
Zinc is involved in over 200 different enzymatic reactions in the body and plays a vital role in DNA synthesis, normal growth and neurological development during pregnancy, childhood, and adolescence. It is also needed for hormone production, immune function, reproductive system, wound healing, taste, and smell. The highest concentration of zinc is found in muscle (65%), brain, liver, kidney, skin, pancreas, eye retina, and in the male prostate gland and sperm. It is therefore critical to test the level of zinc in the body. Since the ability to taste zinc is directly proportional to the body’s reserve of this nutrient, performing a Zinc Taste Test is an easy, cost-effective way of measuring your total zinc status in less than 1 minute.
