Pepsi appears to be removing a controversial and toxic sugar-substitute, Aspartame, and replacing it with Sucralose. in the United States. This will result in a change similar to the substitute of the gas additive Lead with MTBE, another toxic substance to take the place of another. The article notes that Aspartame:
breaks down into its constituent amino acids aspartic acid, methanol and phenylalanine . Methanol breaks down further into formaldehyde, formic acid and diketopiperazine. Methanol is a toxin on its own, and its sub-units have been demonstrated as carcinogenic.
Sucralose and Aspartame were both accidentally discovered in a lab. I would not want an accident to be a major part of my food. Perhaps the health-unconscious should stop drinking soda and get some exercise. Otherwise this will end up a a sheeple-cycle of chasing one's tail.
Here is a thorough film, Aspartame: Sweet Misery, on the health effects of Aspartame and how war-hawk Donald Rumsfeld used political connections to push this most-contested food additive ever through the FDA and into the food supply.
