…although a third seem to suffer from conceptual problems! A paper published this week by the British Medical Journal report that children with higher IQs tend to go on to become vegetarian.
Adults who classified themselves as vegetarian tended to be five points higher in IQ when they were tested at age 10.
Interestingly, the results remained stable after education and social class were controlled for.
However, a third of people who classified themselves as vegetarian ate chicken or fish, suggesting most people work with a reasonably flexible definition.
This study is from a research group in Southhampton who are looking at the link between childhood factors and adult brain development.
We recently reported on an earlier study on childhood head size and IQ.
