News:An intelligence-boosting gene in newborn babies explains why breast-feeding raises a child's IQ, scientists have found.

Children with a particular version of the gene perform significantly better in IQ tests if they have been breast-fed as infants. On average, breast-feeding adds seven points to their IQ scores, even after allowing for different social backgrounds. The gene, FADS2, is closely involved in the way the body processes fatty acids in the diet.
