Health Benefits of Zinc and 26 Food Sources
Zinc is an essential trace element for humans, animals and plants. It is vital for many biological functions and plays a crucial role in more than 300 enzymes in the human body. The adult body contains about 2-3 grams of zinc. Zinc is found in all parts of the body: it is in organs, tissues, bones, fluids and cells. Muscles and bones contain most of the body’s zinc (90%). Particularly high concentrations of zinc are in the prostate gland and semen.
Children – vital for growth and cell division
Zinc is especially important during pregnancy, for the growing fetus whose cells are rapidly dividing. Zinc also helps to avoid congenital abnormalities and pre-term delivery. Zinc is vital in activating growth – height, weight and bone development – in infants, children and teenagers.
Zinc – vital for fertility
Zinc plays a vital role in fertility. In males, zinc protects the prostate gland from infection (prostatitis) and ultimately from enlargement (prostatic hypertrophy). Zinc helps maintain sperm count and mobility and normal levels of serum testosterone.
In females, zinc can help treat menstrual problems and alleviate symptoms associated with premenstrual syndrome (PMS).
Zinc – vital for the immune system
Among all the vitamins and minerals, zinc shows the strongest effect on our all-important immune system. Zinc plays a unique role in the T-cells. Low zinc levels lead to reduced and weakened T-cells which are not able to recognize and fight off certain infections. An increase of the zinc level has proven effective in fighting pneumonia and diarrhea and other infections. Zinc can also reduce the duration and severity of a common cold.
Zinc – vital for taste, smell and appetite
Zinc activates areas of the brain that receive and process information from taste and smell sensors. Levels of zinc in plasma and zinc’s effect on other nutrients, like copper and manganese, influence appetite and taste preference. Zinc is also used in the treatment of anorexia.
Zinc – vital for skin, hair and nails
Zinc accelerates the renewal of the skin cells. Zinc creams are used for babies to soothe diaper rash and to heal cuts and wounds. Zinc has also proven effective in treating acne, a problem that affects especially adolescents, and zinc has been reported to have a positive effect on psoriasis and neurodermitis.
Zinc is also used as an anti-inflammatory agent and can help sooth the skin tissue, particularly in cases of poison ivy, sunburn, blisters and certain gum diseases.
Zinc is important for healthy hair. Insufficient zinc levels may result in loss of hair, hair that looks thin and dull and that goes grey early. There are also a number of shampoos which contain zinc to help prevent dandruff.
Zinc – vital for vision
High concentrations of zinc are found in the retina. With age the retinal zinc declines which seems to play a role in the development of age-related macular degeneration (AMD), which leads to partial or complete loss of vision. Zinc may also protect from night blindness and prevent the development of cataracts.
Natural Food Sources of Zinc

Spinach may not be the food with the most Zinc in it, but it holds its own considering that it’s a plant source.

Ask your butcher for lean cuts, or simply pick out ones that have less visible fat at the store. Serving Size (100 grams), Zinc (8.66 milligrams), 264 calories.
24. Cashews
These healthy nuts are sometimes avoided because of the Nutrition Information label which shows how high in fat they are. But much of their fat content is monounsaturated, a healthy fat.
