Higher Childhood IQ Linked to Longer Life: Top 5 Foods to Boost Brain Power

While a range of lifestyle factors have been linked to triggering ailments like cancer, diabetes, hypertension among others, experts have now established an unusual link between IQ level and a range of diseases. Experts at the University of Edinburgh in the UK have found that kids with higher intelligence have a lower risk of major causes of death, including heart disease, stroke, and smoking related cancers. The findings also suggested lifestyle factors, especially tobacco smoking, as an important component in the effect of intelligence on differences in mortality.

Close to 30,000 men and women were examined for the same and it was found that higher childhood intelligence was associated with a lower risk of death until age 79. Previous studies have shown that, on average, individuals with higher IQs tend to live a little longer than those with lower IQs. Cause of death included coronary heart disease, stroke, specific cancers, respiratory disease, digestive disease, external causes (including suicide and death from injury), and dementia.


While the Intelligence Quotient of a person rests on genetic predisposition and can be honed by cognitive exercises and brain stimulating activities, experts suggests diet to also play an active role in boosting brain power. Take a look at top 5 food items that can rev up your IQ.
