Minds of children benefit long-term from breastfeeding

The recently released results of a long-term study conducted by the Federal University of Pelotas in Brazil adds to the long list of benefits of breastfeeding—it can lead to a higher IQ as an adult. The study was launched in 1982, and followed 3,500 babies from all walks of life who were breastfed for various lengths of time. Their IQs were tested 30 years later. Adjusting for socio-economic factors, the results show that people who breastfed for longer generally had higher IQ test results, spent more time schooling and made more money—though the researchers did not account for levels of intellectual stimulation or bonding between mother and child.
