Intelligent children are more likely to become vegetarians later in life, a study says. A Southampton University team found those who were vegetarian by 30 had recorded five IQ points more on average at the age of 10.
Researchers said it could explain why people with higher IQ were healthier as a vegetarian diet was linked to lower heart disease and obesity rates.
The study of 8,179 was reported in the British Medical Journal.
Twenty years after the IQ tests were carried out in 1970, 366 of the participants said they were vegetarian – although more than 100 reported eating either fish or chicken.
Men who were vegetarian had an IQ score of 106, compared with 101 for non-vegetarians; while female vegetarians averaged 104, compared with 99 for non-vegetarians. – bbc
So, on average, vegetarian women are slightly above average and non-vegetarian women are just below average intelligence. Of course, the way averages work, there probably some carnivorous female geniuses.
