Or, why you should not use artificial sweeteners. This is from: http://www.naturalnews.com/034320_aspartame_sweetener_side_effects.html
Over a billion people consume aspartame in their foods and beverages across the world, believing it to be a safe ingredient, but what they probably don’t know is that aspartame currently accounts for over 75% of all side effects complaints received by the FDA’s Adverse Reaction Monitoring System (ARMS) for the past 4 years. It is banned by health-conscious countries all over the world, especially where there is a national healthcare system in place.
If you need to sweeten something, try stevia. It is a natural product, 30 times sweeter than sugar and has NO calories.
