From the expert

Zinc is found in cells throughout the body and is needed for keeping the immune system healthy as well as supporting cell division, cell growth and wound healing. It is also necessary for your sense of taste and smell. Zinc the removes toxic metals from the brain, such as copper, lead, cadmium, and mercury. 

You can become deficient in zinc if you don't eat enough foods containing zinc or if you have problems in absorbing the nutrients in food. Signs of zinc deficiency includes hair loss, skin lesions and slow healing wounds, and diarrhoea. Our bodies need only small amounts of zinc to function properly. Zinc can be found in red meat, poultry, pulses, seeds and nuts although the zinc found in plant-based sources is not absorbed as efficiently as the zinc in meat or shellfish. For this reason, people on plant-based diets may be at higher risk of zinc deficiency.

Even though zinc is an essential requirement for a healthy body, too much zinc can be harmful. Excessive absorption of zinc can also suppress copper and iron absorption.
