Researchers from University of California and University of Pittsburgh have found that women with curvier bodies tend to have a higher IQ compared to women who have straight or round bodies. Curvier women also appear to have more intelligent children according to the longitude study that took place between 1984 and 1994. The body shape associated with intelligence is also described as ‘hourglass’ and consists of larger hips and considerably thinner waist.
Scientists explain their discovery with the fact that women with hourglass-figures have more Omega-3 fatty acid stored in their bodies which is extremely necessary for the proper growth of the baby’s brain during pregnancy. Larger figured women appear to have more Omega-6 in their bodies which is less suitable for brain growth. Too thin women lack both Omega-3 and Omega-6.
Omega-3 is found in fatty fish such as salmon, mackerel, herring, anchovies and sardines. Omega-6 is found in vegetables oils, whole-grains, eggs and poultry but it’s prevalence in the human body has been associated with the presence of more diseases. All those foods are found to be beneficial for adults and thus for pregnant women.
The study also found upper-body fat to have a negative effect on the supply of fatty acids which are essential for the neurodevelopment while lower-body is found to be beneficial. Therefore, scientists claim that the waist-hip ration can give significant indications regarding women’s cognitive abilities as well as their children’s.
