每个人都想让自己变得越来越聪明，于是商家生产出很多产品旨在增强大脑功能，助你越变越聪明。这些保健品的广告也是铺天盖地地在各电视台轮番播出。但是变聪明的方法除了吃一些健脑产品之外，还有什么办法呢？

    据一项调查研究表明：吃素的人会比一般的人更聪明一些！难道说要想边聪明，那就多吃素？究竟是怎么回事呢？这其中有没有科学依据呢？下面我们就通过这篇文章来分析一下吧。

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.

The researchers, from the University of Southampton, tracked the fortunes of more than 8,000 volunteers for 20 years.

They found that those who were vegetarians by the age of 30 had recorded five points more on average at the age of 10.

Further analysis of the results showed those who were brainiest as children were more likely to have become vegetarian as adults.

The typical adult veggie had a childhood IQ of around 105 - around five points higher than those who continued to eat meat as they grew up.

The vegetarians were also more likely to have gained degrees and hold down high-powered jobs. However, these differences were not reflected in their annual income, which was similar to that of non-vegetarians.

There was no difference in IQ between strict vegetarians and those who classed themselves as veggie but still ate fish or chicken. However, vegans - vegetarians who also avoid dairy products - scored significantly lower, averaging an IQ score of 95 at the age of 10.
