Jello is a sweet, fruit-flavored food that's thickened with gelatin. When you're recovering from having your wisdom teeth removed, jello may be the only thing you feel like eating for a while.
Desserts made with gelatin are often generally referred to as jello (or jelly in the U.K.) although the official trademarked name is Jell-O. This light, sweet treat is a favorite of kids who like its bright colors and jiggly consistency. It's also common in hospitals, since eating jello is an easy way for patients to get extra hydration. So-called "jello salads" contain fruit, marshmallows, and nuts, suspended within the molded jello.
