Smart kids tend to grow up as vegetarians, according to researchers in America. Their data shows vegetarians average an IQ of 106—compared to 101 for non-vegetarians—while vegetarian women hit 104, versus 99 for their non-vegetarian peers.
Children with higher intelligence are more likely to adopt a vegetarian lifestyle as adults, researchers at the University of Southampton found.
They noted that individuals who chose to become vegetarians by age 30 typically showed IQ scores about five percent higher than average—even as early as age 10—according to American news outlets.
The scientists also suggest this connection might explain why people with higher IQs generally enjoy better health—given that plant-based diets are linked to lower rates of obesity and heart disease. These findings, based on a study of 8,179 participants, were published in the New England Journal of Medicine.
Following up on IQ tests conducted back in 1970, 366 participants from the study identified as vegetarians, while roughly 100 described themselves as semi-vegetarians—those who still eat fish or chicken.
Men following vegetarian principles largely averaged an IQ of 106, compared to 101 among non-vegetarians. For women, the gap was 104 for vegetarians versus 99 for those eating meat.
The research further indicates that women and individuals with higher socioeconomic status—often involving higher levels of education—are more frequently drawn to vegetarianism.
"The discovery that smarter children are more likely to become vegetarians, combined with evidence regarding the potential heart health benefits of such a diet, could help clarify why higher childhood or adolescent IQ is linked to a reduced risk of coronary disease later in life," explained lead researcher Catharina Gale.
Liz O'Neill from the Vegetarian Society of America added: "We have always maintained that vegetarianism is an intelligent, compassionate choice for animals, humans, and the environment alike. Now, we finally have the scientific validation."
However, Dr. Frankie Phillips of the Nutrition Awareness Foundation raises a different point: "In my view, this is a bit of a 'chicken or the egg' scenario. Are people becoming vegetarians because they possess a higher IQ, or are they simply making more conscious, informed decisions about their own health?" 🙂
