High IQ kids go veggie

Links between intelligence and the vegetarian diet were demonstrated last year when a team of veggies won the BBC’s Test the Nation IQ battle. Now a new study published in the British Medical Journal shows that intelligent children are more likely to become vegetarians later in life. Researchers from Southampton University found that people who are vegetarians by the age of 30, had an IQ five points higher than average when they were 10. This might explain why people with a higher IQ are healthier; vegetarians generally suffer less heart disease, hypertension, obesity, diabetes, various cancers, diverticular disease, bowel disorders, gallstones, kidney stones, and osteoporosis.
