An adequate zinc intake enhances the ability to taste, promotes healthy skin and hair, enhances reproductive functions, and may improve short-term memory and attention span.

Zinc is sometimes used to treat acne, rheumatoid arthritis, and prostatitis. Levels of zinc may be decreased by diarrhoea, kidney disease, diabetes or too much fibre. Do not take zinc tablets at the same time you take iron tablets.

Too much zinc can impair immune function and cause nausea, headaches, vomiting, dehydration, stomach aches, poor muscle coordination, fatigue, and possibly kidney failure. Always try to increase your zinc levels by eating the foods rich in this mineral.
