Muscling in a bit on Jello's territory, Hunt has sugar free gelatin snacks that need no refrigeration and have 10 calories / 2g carbs per serving.
The gel is sweetened with maltitol and sucralose, but really there's hardly any of either. This really shouldn't cause any trouble for anyone, even those sensitive to sugar alcohols.
It really is very Jello-like, as you might imagine. It has a nice cherry flavor, a nice color, it's in general a nice, easy treat.
Sure, it's better to eat snacks that are natural and healthy for you, but that's not always possible. Sometimes you want something mindlessly sweet and comforting. This is perfect for popping into a lunchbox or keeping in an office desk for a snack that won't go bad.
