Researchers in Kenya have published findings that should give pause to those promoting vegetarianism in children. The study looked at four groups of children. One group received a plant-based stew with added meat, one group got stew without meat plus whole milk, one group got the stew with added oil, and the fourth group served as a control. Students got the special meals for five consecutive terms. Those getting the stew plus meat showed significantly greater improvements in test scores than those in all the other groups while those getting the stew plus milk outperformed those getting the stew with oil and the control group. The researchers credited increased folate, iron, vitamin B12, zinc and riboflavin as nutrients that contributed to better cognitive function (Br J Nutr. 2014 Mar 14;111(5):875-86).
