Zinc Nutritional Facts
Zinc is an essential mineral in our bodies.
Ideally, we should eat some zinc every day, because we cannot store it in our bodies.
The recommended dietary allowance of zinc is:
• 11 mg for men
• 8 mg for women
Dietary allowances for all ages are shown in the Data Zone.
We need zinc in our bodies for:
• protein and DNA synthesis
• normal growth and development
• enzyme function
• immune system function
• good reproductive health in males
• wound healing
• our taste and smelling senses
As a dietary supplement, zinc is available in a variety of forms such as:
• zinc gluconate
• zinc sulfate
• zinc acetate
High doses of zinc can be harmful.
For example, excess zinc can reduce the amount of copper our bodies can absorb, causing anemia. (Our bodies need copper to facilitate hemoglobin synthesis.)
You can see a list of foods that are high in zinc by scrolling a little farther down this page.
The list shows the amount of zinc in a standard portion and also the percentage of recommended daily allowance.
Like iron, our bodies absorb zinc more easily from meat than from plant sources.
The reason for this is that plants contain substances which reduce zinc absorption a little – phytates, found in wholegrain bread, legumes, and cereals – and oxalates, found in leafy vegetables – reduce our ability to absorb zinc from food.
Despite this, these foods are still good sources of zinc.
