13 Oct 2022 --- A study published in Lancet Global Health has revealed that half of preschool-aged children and two out of three women of reproductive age are experiencing “hidden hunger” – nutrient and mineral deficiency of either zinc, iron, folate or vitamin A – globally. “Women of reproductive age have increased iron requirements, and folate deficiency during this period can increase the risk for neural tube defects in a developing fetus if a woman becomes pregnant,” Ty Beal, research advisor of knowledge and leadership at the Global Alliance for Improved Nutrition (GAIN), tells NutritionInsight.
