I was searching the correlation between drinking soft drinks and IQ, because I wanted to verify if countries that drank a lot of coke/soft drinks were more likely to have more intelligent populations (e.g. the basic rationale was that sugar in carbonated drinks would speedup brain faculties, thus having more synapses, and overall better brain performance)
I found in that 2012 NCBI article citing the following:
A total of 529 children participated in this study, (77.7%) of the children have high IQ level. Almost (60%) of the children drink carbonated drink daily, while (74%) eat chips every day. The association between drinking carbonated drinks, eating chips and intelligence level was significant (P= 0.043, 0.001) and prevalence odds ratio of 1.5 and 2.4 respectively.
And the study concludes with:
There were significant associations between carbonated drinks, chips intake and IQ score. More regulations on what to sell inside the schools canteen are needed. Increasing nutritional knowledge of the parents, especially the mothers is very important and more health promotions should be given regarding children nutrition in the early years of school.
Am I reading this right, that junk food and drinking soft drinks is correlated with higher intelligence quotient ? Does all that sugar beside its negative side effects (tooth decay, insulin highs) have this positive effect on intelligence ?
