| Zinc Deficiency and RDA [Infographic] from Naturalhealthyconcepts.com |
Zinc promotes immune function and wound healing, supports healthy cell growth and development, and accelerates the catalytic activity of approximately 100 enzymes. It is also thought that zinc aids in balancing blood sugar, enhancing thyroid hormone production and promoting a stable metabolic rate - these three functions of zinc, together with some recent studies, suggest that zinc may play a role in boosting metabolism and aiding in weight loss.
Since the majority of Americans get adequate amounts of zinc on a daily basis from meat and poultry, most Americans likely do not have a zinc deficiency.
However, the NIH warns that a daily intake of zinc is required to maintain a steady state because the body has no specialized zinc storage system.
Furthermore, apparently whole-grain breads, cereals, legumes and certain other foods contain "phytates". Phytates bind zinc and inhibit its absorption. It is suggested that vegetarians and vegans (who eat a lot of whole grains and legumes) may require higher daily zinc intakes - as much as 50% more of the RDA than non-vegetarians.
Other groups at risk for zinc deficiency include pregnant and lactating women, alcoholics, and individuals with gastrointestinal and other diseases.
This infographic illustrates some of the signs and symptoms of zinc deficiency and common food sources of zinc. It also includes a chart of the recommended daily amount of zinc.
