Are those ingredients for chewing gum or something?Sucralose is an artificial sweetener used in place of other artificial sweeteners like Aspartame which is believed by many to metabolize into something bad for you in the kidneys. Forget all the details. It's still an on-going debate but Sucralose is supposed to be more healthy.

Just go down to the "Public health and safety concerns" section. (Yea, lots of scholars still don't consider wikipedia a reliable source but many now do.)
I know maltodextrin isn't bad. People on a bodybuilding forum I go to for information use maltodextrin in their home-made protein shakes as an alternative to a carbohydrate like oatmeal or something like that. Although a lot of them would also say just to skip the maltodextrin and throw in actual oatmeal.
"Usually made from rice, corn, or potato starch, maltodextrin is produced by cooking down the starch."
Glucose Syrup is another word for High Fructose Corn Syrup. It's not pure sugar from a source like sugar cane. I'm pretty sure you can find arguments going both ways on whether or not this is healthy for you but it's found in pretty much anything and everything these days if you're in the US unless you plan on eating all organic fruits and vegetables and getting meat straight from a farmer.
The rest of the stuff seems fairly standard as something you'd find in a lot of other products so off the top I'd say probably not a big concern although don't take my word for it.
Antioxidants are a good thing (I don't know how to differentiate between all the different types of them though).
Tricalcium Phosphate I think is a type of calcium that's absorbed through the enamel of your teeth to strengthen them (which is why I'm assuming these are gum ingredients... probably the Trident stuff that they're marketing now).
Anything in large amounts is bad for you, even the healthiest stuff. Gotta take things in moderation. But for the most part I think you'd have to get individual bags of the ingredients and eat unnatural amounts of them to get any real negative effect.
