– This is why you should never bake with Splenda (TreeHugger, Jan 28, 2014):
Sucralose is a synthetic sweetener made from reacting sugar with chlorine. Marketed as “Splenda,” it was approved for sale in the United States in 1998, though it had been previously sold in Canada, Europe, and elsewhere. Since then, Splenda has become popular as a “no calorie sweetener,” according to its paper packaging. Sucralose has long been considered a safer alternative for sweetener than aspartame because it doesn’t break down at high temperatures, but now researchers have discovered a scary side effect to heating sucralose.
A study review recently published in the Journal of Toxicology and Environmental Health says that baking or cooking with Splenda releases cancer-causing dioxins into the food. The process of heating and cooking generates chloropropanols, a potentially toxic class of chemicals that may be linked to higher risk of cancer.
