especially aspartame and acesulfame potassium. I have easily found (on the internet) how much of these two substances are considered safe. What I haven't found is how much of these substances are found in a particular product. For example, 15 mg per kilo of body weight is an acceptable amount of acesulfame potassium per day...but i have no idea how much is in...a piece of gum, a soda. Anyone have any links to such information? Thanks.
