The researchers found that 4.5 percent of participants were vegetarians. Of these, 2.5 percent were vegan(6), 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.

英国研究人员发现小孩智商可以预示成年后变成素食者的可能性,也就是降低心血管疾病的几率。研究人员说此项研究能够解释为什么聪明的人会更健康。
流行病信息中心高级研究员、本研究主要作者Catharine Gale说:聪明的人一般选择较健康的饮食习惯。
最近的研究显示素食有利于降低胆固醇吸收、减少肥胖和心脏病几率。这也是为什么高智商的孩子在晚年不容易患心脏病的原因。
