Abstract
Over 200 million children worldwide suffer from malnutrition and, as a result, are underdeveloped both physically and mentally. Meat has more bioavailable essential micronutrients than plants and is the best source of nutrient-rich foods for children aged 6 to 23 mo, according to the World Health Organization. By consuming meat, which contributes essential bioavailable micronutrients to diets, children in particular can reduce undernutrition and the associated growth and cognitiveimpairment. This review aims to elucidate the effect of meat consumption on cognitive development by systematically reviewing and synthesizing results from available studies. Of 241 pertinent studies initially retrieved from the literature, only 9 met the inclusion criteria, and these included 28 cognition variables covering data from 10,617 children aged 3 mo to 17 y. Twelve(42.8%) of the variables showed improvements in cognition with increased meat consumption, 6 (21.4%) showed no effect,and 10 (35.7%; including 8 from HIV-positive children) showed a decrease in cognition with increased meat consumption.Across all variables, the study reveals some evidence of an association between meat consumption and improved cognition,which becomes more compelling when data from the HIV-positive children are excluded. More research on the effect of meat consumption on cognitive development from randomized controlled studies is needed.
