From a study done at the Department of Epidemiology, Graduate School of Public Health, University of Pittsburgh:
Upper-body fat has negative effects and lower-body fat has positive effects on the supply of long-chain polyunsaturated fatty acids that are essential for neurodevelopment. Thus, waist-hip ratio (WHR), a useful proxy for the ratio of upper-body fat to lower-body fat, should predict cognitive ability in women and their offspring.
Non-Politically Correct Translation:
Due to greater store of omega3 fatty acids, curvy women and their children have higher IQs than do skinny women and their children.
Many of us men and women did not need a study to know this already. But has a similar beer research study been funded?
