Forive me if someone has already posted this, but there is some evidence of dietary 'programming' in rats through breastfeeding. The pups learn what to eat through flavors in their milk. This would probably apply to human infants as well. Kathy D.: could this be a contributor to the persistence of food ways (cultural dietary preferences) long after other culture-of-origin practices have been abandoned by immigrants? Just another reason why we should not counsel mothers to unneccessarily restrict their diets while lactating... Catherine Watson Genna, IBCLC NYC [log in to unmask]
