Wrong. Eating more jelly can not only supplement nutrition, but even hinder the absorption of some nutrients. Carrageenan, the basic component of jelly, is a carbohydrate that the human body can't absorb, and it doesn't contain fruit juice. Its sweetness comes from refined sugar and its fragrance comes from artificial essence. Fortunately, there is no fat in jelly, and it also contains water-soluble dietary fiber. Eating a small amount won't make you fat, but you can't expect it to increase nutrition.
