My suggestion is the obvious one - read the package.
I would have serious concerns about the aspartame that seems to be in every thing - even things that already have sugar.
I went to pick up a simple package of gum the other day - and couldn't find any that didn't have it in it - no one package.
Considering that in October 1980 the Public Board of Inquiry (PBOI) impaneled by the FDA to evaluate aspartame safety found that the chemical caused an unacceptable level of brain tumors in animal testing. Based on this fact, the PBOI ruled that aspartame should not be added to the food supply - but in July 1981 Hayes, defying FDA advisors, approved aspartame for dry foods -- his first major decision. In November 1983 the FDA approved aspartame for soft drinks -- Hayes' last decision.
In November 1983 Hayes, under fire for accepting corporate gifts, left the agency and went to Searle's public-relations firm as senior medical advisor. Later Searle lawyer Robert Shapiro named aspartame NutraSweet. Monsanto purchased Searle. Rumsfeld received a $12 million bonus. Shapiro is now Monsanto president.
If you really want to eat healthy - there are many things to take into consideration.
