Aside from gelatin, which provides structure, the ingredients in marshmallows include sugar, corn syrup, and water, according toFood Network. Sometimes they contain other ingredients that alter the taste or color. Vegetarians and vegans can’t eat traditional marshmallows because gelatin is made with animal protein. There are also marshmallows made from plants like seaweed. They are similar in taste but less fluffy.
As you can see, marshmallows do not have any nutritional value. Like most sweets, marshmallows aren’t going to cause you any health problems. However, it is possible to indulge in them every now and again. That said, SFGate reports that if you eat burned marshmallows too often, it could be unhealthy. The reason is that food can become more toxic if it’s intentionally cooked. You can enjoy marshmallows raw or lightly toasted rather than charred.
