As a child's IQ rises, his taste for meat in adulthood declines, a new study suggests.
British researchers have found that children's IQ predicts their likelihood of becoming vegetarians as young adults -- lowering their risk for cardiovascular disease in the process. The finding could explain the link between smarts and better health, the investigators say.
Recent studies suggest that vegetarianism may be associated with lower cholesterol, reduced risk of obesity and heart disease. This might explain why children with high IQs tend to have a lower risk of heart disease in later life.
"Children who scored higher on IQ tests at age 10 were more likely than those who got lower scores to report that they were vegetarian at the age of 30," Gale said.
The researchers found that 4.5 percent of participants were vegetarians. Of these, 2.5 percent were vegan, and 33.6 percent said they were vegetarian but also ate fish or chicken.
There was no difference in IQ score between strict vegetarians and those who said they were vegetarian but who said they ate fish or chicken, the researchers add.
Vegetarians were more likely to be female, of higher social class and better educated, but IQ was still a significant predictor of being vegetarian after adjustment for these factors, Gale said.
"Vegetarian diets are associated with lower cardiovascular disease risk in a number of studies, so these findings suggest that a such a diet may help to explain why children or adolescents with a higher IQ have a lower risk of coronary heart disease as adults," Gale said.
As the study showed, more women than men chose a vegetarian diet, Sandon noted. "Other research shows that women in general will focus more on their health than men. So, if they believe that a vegetarian diet will have health benefits, they are more likely to follow it," she said.

Hmmm interesting study...does that make vegetarians smarter overall? Just kidding :)
But seriously I think people who do think deeper become vegetarians because there is no way you can accept what happens to animals on our account and eat meat at the same time.
