Meat is Great

A study by nutritionists, reported at the current conference of the AAAS, shows that vegetarian diets can damage children's health. See here for a news report. (Search Google News for the name 'Lindsay Allen' for more coverage.) But the most interesting part of the study is that it followed the effects of giving dietary supplements to Kenyan schoolchildren. Some were given meat (2 ounces a day, equivalent to a small hamburger), some were given extra calories but not meat, and a control group were not given supplements. The results showed large improvements in IQ (fluid intelligence) for the 'meat' group. This seems relevant to the debate over international IQ differences, particularly in Africa, and to the causes of the 'Flynn Effect'.
