About Zinc
Zinc is essential for the activity of over 300 enzymes and plays structural roles in thousands of proteins. It is critical for immune function, wound healing, DNA synthesis, cell division, taste and smell, and normal growth. Plant sources include pumpkin seeds, hemp seeds, chickpeas, lentils, oats, cashews, and wholegrains. Phytates in plant foods reduce zinc absorption by 15–35% compared to animal sources — plant-based diets may need 50% more zinc than omnivorous diets to achieve equivalent absorption.
Impaired immune function, frequent infections, slow wound healing, hair loss, loss of taste and smell, skin problems, and in children, growth retardation. Deficiency is a significant global public health issue and a genuine risk on unplanned plant-based diets.
High-dose zinc supplements interfere with copper absorption, leading to copper deficiency (anaemia, neurological symptoms). GI distress occurs at high single doses. The tolerable upper intake level is 25 mg/day for adults.
