I drink 1% milk, eat cheese in recipes, eat yogurt, and can tolerate various dairy products, but have noticed over the past several months that if I eat "regular" ice cream from a local creamery, I begin to have stomach pains, gas, and diarrhea...is it possible that I could be "partial" lactose intolerant or have I become so accustomed to "lighter" dairy products, my body has a harder time processing "regular" dairy products?
