A cereal bar or granola bar is a convenient, portable snack typically made from rolled oats, nuts, seeds, and a sweet binder like honey or syrup, often combined with dried fruits or chocolate chips. Originating in the United States, it evolved from early 20th-century health food trends into a mainstream, on-the-go energy source.
These bars are generally high in carbohydrates for quick energy, with moderate fat from nuts and oils, and variable protein depending on added ingredients like whey or soy. A standard 40-50g bar provides around 150-200 calories, along with fiber, iron, and B vitamins.
