Some facts about artificial sweeteners that made me change my mind:
1. They are chemicals or natural compounds that replace the sweetness of sugar, without all of the calories. But sometimes the label ‘sugar-free’ masks calories present in the food or drink. Of course you can always read the product’s label, but believe it or not, there are a whole lot of people out there who think that sugar-free or fat-free means low-calorie. On top of that, there are some recent studies that have shown that artificial sweeteners can actually increase your appetite. And then there are sugar-free products with ingredients that can raise your blood sugar dramatically—like the white flour in sugar-free cookies. All in all, ‘sugar-free’ doesn’t always mean ‘diet-friendly’.
2. Aspartame (NutraSweet, Equal, NatraSweet, Canderel, Spoonfuls, DiabetiSweet) is a common chemical sweetener with possible side effects that sound like they’re out of a horror movie. From hallucinations to seizures to brain tumors, it is hardly worth consuming for the sake of saved calories.
3. Sucralose (Otherwise known as Splenda, my past-sweetener of choice), is scary. Recent research suggests that Splenda can enlarge both the liver and kidneys and shrink the thymus glands. Sucralose breaks down into small amounts of dichlorofructose, which has not been tested adequately tested in humans. Splenda reportedly can cause skin rashes, panic, diarrhea, headaches, bladder issues, stomach pain, and those side effects don’t even sum it up.
