QBeth, there are two things going on with the excess fat around the midsection. One is high fructose corn syrup - there is a direct correlation and the other is the phalates in the plastic, especially if they are microwaved. A teenager with a small waistline is a rarity these days. So many muffin tops. When I researched why, this was what turned up repeatedly.
You think you are phalate free because you use phalate free bottles? Look inside the next can of vegetables you open - guess what the white lining is? (By the way, this is the generic you - nothing personal).
