Found out the brand Splenda which is sucrolose which is a synthetically made sugar. This shit is worse for your body than regular high sugar sodas. Sucrolose/Splenda are included in these beverages: diet soda/flavored water/ 0 or 1 calorie sodas/ Gatorade's propel fitness water. Cake mix and other baking products are now starting to use it as well. Aspartame is the other ingredient you should look out for, just as bad if not worse than sucrolose.
