energy bar

A typical energy bar weighs between 30 and 50 grams and is likely to supply about 200–300 calories (840–1,300 joules), 3–9 grams of fat, 7–15 grams of protein, and 20–40 grams of carbohydrates — the three sources of energy in food.{{cite web|title=Nutrition Bar Comparison Chart|url=http://www.mesaaz.gov/fire/wellness/pdf/nutritionbarcomparisonchart.pdf|url-status=dead|archive-url=https://web.archive.org/web/20100527180845/http://www.mesaaz.gov/fire/wellness/pdf/NutritionBarComparisonChart.pdf|archive-date=27 May 2010|access-date=21 October 2009|publisher=Mesa AZ fire department}} 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.
