第一篇
The Relationship between IQ and Being a Vegetarian
A Southampton University team found that people who were vegetarians (素食主义者）by 30 had recor-
ded five IQ points higher on average at the age of]U.Researchers said it could explain why people with a
higher IQ were healthier as a vegetarian diet was linked to lower heart disease and obesity（肥胖）rates.The
study of 8,179 people was reported in the british Medical Journal.
Twenty years after the IQ tests were carried out in 1970,366 of the participants said they were vegetarians一
although more than 100 reported eating either fish or chicken.
Men who were vegetarians had an IQ score of 106,compared with 101 for non-vegetarians;while female
vegetarians averaged 104,compared with 99 for non-vegetarians.There was no difference in the IQ scores
between strict vegetarians and those who said they were vegetarians but reported eating fish or chicken.
Researchers said the findings were partly related to better education and higher class,but it remained
statistically significant after adjusting for these factors.
Vegetarians were more likely to be female,to be of higher social class and to have higher academic or
vocational qualifications than non-vegetarians.However,these differenIces were not reflected in their annual
income,which was similar to that of non-vegetarians.
Lead researcher Catharine Gale said,"The findings that children with greater intelligence are more likely to
report being vegetarians as adults,together with the evidence on the potential benefits of a vegetarian diet on
heart health,may help to explain why a higher IQ in childhood or adolescence is linked with a reduced risk of
coronary heart disease in adult life."
But Dr Frankie Phillips of the British Dietetic Association said, "It is like the chicken and egg."Do
pcople become vegetarians because they have avery high IQ or is it just that they are clever enough to be
more aware of health issues?
What does the underlined sentence in the last paragraph mean?
A.Intelligence is linked to not just being a vegetarian but many factors.
B.The rate of getting heart disease is linked to your lifestyle.
C.The link between a high IQ and being a vegetarian is still uncertain.
D.The link between a healthy heart and diet remains to be proved.
