Is there a problem here?

HOW SWEET IT ISThe relative potency of sugar compared with artificial sweeteners.

sugar                                      1x

cyclamate                           45x

aspartame                        180x

saccharin                          300x

sucralose                          600x

neotame13,000x

Discover Magazine: August 2005, The Chemistry of Artificial Sweeteners

When the sweetener aspartame is digested, its methyl ester bond is broken down into methanol, which further degrades into formaldehyde. Both methanol and formaldehyde are toxic in high doses, but a person would have to drink 600 cans of diet soda to get as much of either substance as is contained in a single orange.
