British Medical Journal published the results of these studies, where researchers measured the IQ of a number of respondents at age 10 and then follow their progress until the age of 30 years. Existing data show that those who become vegetarian when children have an IQ of about five points higher than the average adult who is not vegetarian.
They are vegetarians were also more likely to have jobs and a higher degree. This is due, according to the researchers, a diet rich in vegetables and fruits can improve the ability of the brain among other health benefits to improve intelligence.
"Studies have also shown that vegetarian kids grow taller and have higher IQs than their schoolmates. The risk for heart disease, obesity, diabetes and other diseases also declined for the long term," commented People for the Ethical Treatment of Animals (PETA), an institution that animal rights campaigning.
However, the results of this research still raises questions. Are smart kids who decided to become a vegetarian when I grew up, or did they become vegetarians in order to become more intelligent? Those with higher intelligence may be more to consider ethical issues, such as the welfare of animals, and also the health benefits of eating lots of vegetables.
