Many of us like to consume marshmallows as a delicious treat with hot chocolate, on top of sweet potatoes, or even molded into Peeps for Easter. However, these light white puffs aren’t very nourishing. Typically, gelatin, corn syrup, and sugar make up marshmallow ingredients. However, if you consume more than one serving, the calories in marshmallows can mount up rapidly. No other confection has a texture like a marshmallow.
