Energy bar

Because most energy bars contain added protein, carbohydrates, dietary fiber, and other nutrients, they may be marketed as functional foods.

Manufacturing of energy bars may supply nutrients in sufficient quantity to be used as meal replacements.

[3] In order to provide energy quickly, most of the carbohydrates are various types of sugars like fructose, glucose, maltodextrin and others in various ratios, combined with complex carbohydrate sources, such as oats or barley.

[citation needed] Fats sources are often cocoa butter and dark chocolate.

[6] For those who are malnourished, energy bars, such as Plumpy'nut, are an effective tool for treating malnutrition.
