If you haven't tried Mayfield's NuTrish 1% Lowfat Milk,  you should give it a try.  Not only does it taste great, but it's great for you.  Mayfield's NuTrish contains two probiotic cultures; Lactobacillus acidophilus and Bifidobacterium.  Acidophilus and Bifidum are naturally occurring organisms in the human gastrointestinal tract.  Consuming these organisms replenishes the bacterial population which is diminished through aging. 

Mayfield's four flavors of Lowfat Frozen Yogurt also contain these same two "good for you" cultures.  Just look for the blue rim!
