Everybody should be limiting their intake of artificial sweeteners. Aspartame is the worst as it is an excitotoxin. Sucralose is highly questionable. All forms negatively impact how the pancreas releases insulin by confusing the body with a sense of ingesting sugars without the availability of those sugars.

Personally, I find that the key issue is the density of sugars ingested. Sugars with proteins or complex carbs are much better tolerated. I can enjoy an 80 calorie piece of chocolate without even noticing it. I do try to avoid all High Fructose Corn Syrup as I can feel the difference in my system.
