This is an important mineral in appetite control. A deficiency can cause
loss of taste and smell, creating a need for stronger-tasting foods ( which
tend to be sweeter, saltier, and more fattening). Zinc is also needed for
the optimum function of many hormones including insulin which is important
in balancing blood sugar levels. Zinc is mostly found in the strong muscles
of the body and especially in high concentrations in the white and red blood
cells, skin, liver kidneys, pancreas and thyroid. Without Zinc the thyroid
cannot control how quickly the body burns calories and uses energy. Some
bariatric surgeries, such as gastric bypass and duodenal switch work by
malabsorption, meaning that the body blocks the absorption of certain
vitamins and minerals. This can result in serious nutritional deficiencies -
including Zinc.
