[php snippet=1]Zinc is one of the most active minerals in the body as it influences the functioning of hundreds of different enzymes.

Absorption of zinc from the digestive tract is not well understood. However, it does seem that many factors can influence how efficiently zinc is absorbed. For instance, zinc derived from meat boasts better absorption than zinc from plant sources. Zinc absorption from meat may actually be enhanced by certain amino acids, which would be present during simultaneous protein digestion. On the other hand, the efficiency of zinc absorption from plant foods seems to be lower which may in part be due to the presence of phytate, oxalates, and probably other substances (tannins) also found in many plants. Recommendations for dietary zinc takes into consideration the impact of various substances on zinc absorption.

Can Zinc Become Toxic?

Zinc toxicity would tend to happen only by supplementation. One of the biggest concerns with higher zinc intakes is its relationship to copper. It is possible to reduce copper intake and induce signs of copper deficiency by consuming as little as three to ten times the RDA for zinc over several months. Because of the inverse relationship between dietary zinc and copper absorption, the utilization of high zinc supplements is not recommended unless a physician has recognized a need. This is particularly true for people who use zinc supplements to treat the common cold. These supplements should not be continued beyond 5 to 7 days.

The deficiency of zinc causes diarrhea, hair loss, impotence, delayed sexual maturation, eye or skin lesions and hypogonadism in males. Moreover delayed healing of wounds, weight loss, mental lethargy and taste abnormalities could occur.

Excessive presence of zinc causes side effects such as vomiting, nausea, stomach pains, loss of appetite, diarrhea and headaches. High zinc in body also leads to development of kidney stones. In high doses, if zinc is taken orally for long term then it results copper deficiency.
