How much do you know about zinc?
The essential nutrient promotes immune support, nervous system function, and metabolic health. This piece will offer an overview of what zinc is, the recommended daily allowance (RDA) of zinc, and the best form of this trace mineral.
What Is Zinc?
Zinc is the most prevalent trace mineral in the body after iron. In addition to strengthening the immune system and metabolic function, it promotes wound healing and plays a key role in people’s sense of taste, vision, and smell.
Found in every cell, zinc is also involved in reproduction, blood clotting, and insulin and thyroid function. The nutrient’s antioxidant properties help damage from free radicals—which contribute to aging—even going so far as to mitigate the damage they might have already caused.
Zinc is also a necessary cofactor for over 300 enzymes. In this way, it plays a key role in their overall functioning.
In short, zinc is very important. Continue reading to explore common food sources of zinc, and to understand just how much zinc you need for good health. We will even offer much-needed insight into zinc supplementation.
Food Sources of Zinc
The human body absorbs 20-40% of the zinc found in the foods we eat.
Zinc from animal sources like fish and poultry—or from supplements—is absorbed more efficiently than zinc from plant-based food sources like whole grains. This is because phytates, which are more prevalent in plant-based foods, bind zinc and hinder its absorption.
Experts believe zinc is ideally consumed with a meal high in protein. Common food sources of zinc include:
• Oysters (the richest source of zinc) and other shellfish
• Shrimp and crab
• Red meat and poultry
• Cheese (particularly ricotta, gouda, and Swiss)
• Legumes (particularly soybeans, peanuts, pinto beans, and lima beans)
• Miso and tofu
• Green beans and cooked leafy greens
• Sunflower seeds
• Whole grains and fortified breakfast cereals
• Brewer’s yeast
Most people consume enough zinc simply by eating a balanced diet. Others make sure they get enough zinc via supplementation. Regardless of the path you choose, it’s important to note that zinc lowers the amount of copper the body can absorb, and that high doses of zinc may cause a copper deficiency.
Recommended Amount of Zinc
The recommended daily amount of zinc is 8 milligrams (mg) for adult women and 11 mg for adult men. Pregnant and lactating women have an increased RDA of 11 mg and 12 mg, respectively.
The National Institutes of Health has stated that 40 mg of zinc per day is the tolerable upper intake level (UL) for adults, and that 4 mg of daily zinc is the UL for infants under six months.
People in industrialized regions are very rarely severely deficient in zinc. Lower levels of zinc may be found in the elderly, in people with alcoholism or anorexia, and in people adhering to a very strict diet. Malabsorption conditions like celiac disease and Crohn’s disease may also result in a zinc deficiency.
Signs of zinc deficiency may include:
• Loss of appetite
• Weight loss or slowed growth
• Loss of taste or smell
• Hair thinning or loss
• Slow wound healing
• Skin issues including acne
• White spots on the fingernails
Consult your doctor if you think you may be experiencing a zinc deficiency.
