Currently, zinc is a critical determinant nutrient especially in conditions of inadequate nutrition based on foods with low bioavailability of zinc.
This is particularly the case for phytate-rich foods such as unrefined cereals, grains and nuts, consumed as staple foods in many developing countries, but also as part of vegetarian and vegan diets, phytic acid or phytates in the gut. Phytates bind to zinc preventing its absorption.
Zinc is found in a variety of foods, but the highest concentrations of zinc are found in foods of animal origin, particularly in the organs and muscles of cattle, pork, poultry, fish and shellfish and, to a lesser extent, in eggs and dairy products, being low in tubers, refined grains, fruits and vegetables.
Since zinc is considered a necessary nutrient and not available in a wide variety of situations or restricted diets, it can be ingested as a supplement combined with vitamin C or only in the form of tablets.
