British researchers have just conducted a study that found that that the higher the IQ of a person is, the more likely they are to follow a relatively health diet overall. It also indicated, more specifically, that IQ is a reliable predictor of the likelihood of a teen/young adult becoming a vegetarian.
The study looked at over 8,000 men and women around the age of 30 whose IQs had been tested when they were 10 years old. In the group, 33.6% "said they were vegetarian but also ate fish or chicken," 4.5% were strict vegetarians and 2.5% of the strict subset were vegan. Men in the study who were vegetarian had an average IQ score of 106 and female vegetarians averaged a score of 104. Non-vegetarians averaged 101 for men and 99 for women. There was no IQ difference between strict and lax vegetarians and all had a lower risk of heart disease. Even after adjustments were made to account for the fact that more vegetarians were women and that they tended to be better educated than others, IQ was still a significant predictor.
