Systematic Review

Effect of vegetarian diets on zinc status: a systematic review and meta-analysis of studies in humans.

Plant-based diets contain less saturated fat and cholesterol, and more folate, fibre, and phytochemicals than omnivorous diets, however some micronutrients, especially zinc, are poorly bioavailable. The findings of studies exploring the zinc intake and zinc status in populations that habitually consume vegetarian diets are inconsistent. This study aims to investigate the effects of plant-based diets on dietary zinc intake and status in humans using systematic review and meta-analysis techniques. Thirty-four studies were included in the systematic review.
