Artificial sweeteners are unsafe.

  The Internet is flooded with rumors that artificial sweeteners (Splenda, Nutrasweet, etc) can cause ailments such as cancer, multiple sclerosis, dementia, and many others.

  Sucralose (Splenda) is said to be structurally related to the pesticide DDT and causes autoimmune disease.

  Tell people that this is NOT true. The only thing in common between sucralose and DDT is that they both have chlorine atoms. Chlorine is naturally found in many foods, beverages and drinking water. By adding chlorine atoms to sugar, it becomes inert and is not metabolized by the body. The chlorine in sucralose also makes it heat-stable so that it can be used in cooking and baking.
