The not-wife was delighted this morning to read a BBC report that researchers from Southampton University have found that people who were vegetarian by 30 had recorded five IQ points more on average at the age of 10.
The study involved over 8,000 people whose IQs were tested at the age of 10. Of these 366 said they were vegetarian, although more than 100 reported eating either fish or chicken.
Both men and women who stated they were vegetarian had an IQ score five points higher than non-vegetarians. Interestingly there was no difference in IQ score between strict vegetarians and those who said they were vegetarian but who reported eating fish or chicken.
Lead researcher Catharine Gale said: "The finding that children with greater intelligence are more likely to report being vegetarian as adults, together with the evidence on the potential benefits of a vegetarian diet on heart health, may help to explain why higher IQ in childhood or adolescence is linked with a reduced risk of coronary heart disease in adult life." However, she added the link may be merely an example of many other lifestyle preferences that might be expected to vary with intelligence, such as choice of newspaper, but which may or may not have implications for health.
Dr Frankie Phillips, of the British Dietetic Association, said: "It is like the chicken and the egg. Do people become vegetarian because they have a very high IQ or is it just that they tend to be more aware of health issues?"
The story was of interest to the not-wife because, unlike me, she was vegetarian well before the age of 30. .. Another rod to beat me (sighs).
