Regarding Scott Adam's posting, "Safe Gluten-Free Food List (Safe Ingredients)"
I wish Scott wouldn't propagate the notion that artificial sweeteners such as Acesulfame K, Aspartame, or Sucralose are necessarily "safe" to eat. Despite FDA approval, artificial sweeteners have many documented side-effects and many suspected health risks. Gluten is not the only ingredient to be concerned about.
In other words, just because the toxins bleach and formaldehyde are gluten-free doesn't mean I should feel safe to sprinkle a yellow or blue packet in my morning coffee.
Health-conscious individuals will benefit from using only natural reduced-calorie sweeteners that Scott mentioned, such as Xylitol or pure Stevia.
Artificial sweeteners are 'hidden' in so many products - even non-diet ones - that it is an unfortunate challenge to avoid them - so read all ingredients, carefully, all the way through.
Hope this helps!
