Every so often a new study appears that claims that breastfed children are smarter, healthier, or otherwise better off later in life than those who were fed baby formula.

In this episode of The Studies Show, Tom and Stuart look into one recent such study, and ask what the research in general tells us about the apparently-dramatic effects of breastfeeding. Should you feel terribly guilty if you can’t, or choose not to, breastfeed your baby? Or is this an example of weak evidence being blown out of proportion?
