Breastfeeding linked to higher IQ
Researchers in Brazil say that breastfeeding a baby may increase its likelihood of developing a higher IQ, and that babies breastfed longer were more likely to do well on intelligence tests as adults.
The study, published in Lancet Global Health, assessed nearly 3,500 babies, attempting to rule out other environmental factors, such as the mother's education, family income and birth weight. The babies were from many different backgrounds. The researchers said their results supported the belief that babies benefit from being breastfed for at least six months.
While experts agree that breastfeeding provides benefits that baby formula cannot, they agree that not all woman can or want to breastfeed, and that it should remain the woman’s choice.
The study's authors, however, say their research provides more evidence that breastfeeding is a factor that can influence the outcome of children.
