It’s kind of a good news, very bad news situation. The good news: researchers from Bristol University have found a link to higher IQs and better working memory in children. The very bad news: that link is a high risk for eating disorders. According to a new study released Wednesday, children classified as being prone to unhealthy weight control behaviors performed better in tasks that measured the brain’s ability to process necessary information while suppressing irrelevant details. The caveat is, however, that those kids also suffer from poor attention control. And that’s today’s news on studies that connect eating habits to intelligence.
