Red meat reduces the risk of breast cancer!

Oh yum! On the other hand, rabbit food reduces the risk of ovarian cancer...take your pick. Shopgirlove has (pretty much on a whim) assessed herself as having a higher risk of breast cancer. She's feeling downright virtuous about that burger last night. Why, it was positively medicinal! All of this led Shopgirlove to the mother of all dietary time-sucks: the glycemic index. Hoo-boy, you can lose a lot of time on this. What happen to the lovely potato? Why high GI, why?
