"A study of thousands of men and women revealed that those who stick to a vegetarian diet have IQs that are around five points higher than those who regularly eat meat.
Writing in the British Medical Journal, the researchers say it isn't clear why veggies are brainier - but admit the fruit and veg-rich vegetarian diet could somehow boost brain power."
Even though this is almost certainly a bunch of hooey, I am still tempted to explore ways to get the information to certain people I know.
