Many cultures have specific foods or dishes that they believe will help a mother increase her milk supply. Oatmeal and hops are two of them. Many grains, in fact, seem to have a positive effect on milk supply, although there has been very little research to show if this effect is real or how it works. Fenugreek is used in many cultures’ traditional dishes given to new mothers, and there’s even evidence that fenugreek is very helpful in increasing milk supply. In any case, eating a well-rounded diet of healthy fresh foods is your best bet for you and for your baby.
