'''Energy bars''' are supplemental bars containing [[cereal]]s, [[micronutrient]]s, and flavor ingredients intended to supply quick [[food energy]]. Because most energy bars contain added [[protein (nutrient)|protein]], [[carbohydrate]]s, [[dietary fiber]], and other nutrients, they may be marketed as [[functional food]]s.<ref>{{Cite journal|last1=Gill|first1=Aakash|last2=Singh|first2=Ashish Kumar|date=2020-02-29|title=Energy bars: Quick, Healthy and Wholesome Snack for Adolescents|url=https://www.researchgate.net/publication/340396746}}</ref>{{Moved resource|date=January 2023}} Manufacturing of energy bars may supply nutrients in sufficient quantity to be used as [[meal replacement]]s.<ref>{{Cite web|date=2021-01-11|title=How to Choose the Best Health Bars|url=https://health.clevelandclinic.org/health-bars-how-to-choose-wisely/|access-date=2022-01-22|website=Cleveland Clinic|language=en-US|archive-date=22 January 2022|archive-url=https://web.archive.org/web/20220122033802/https://health.clevelandclinic.org/health-bars-how-to-choose-wisely/|url-status=live}}</ref>

==Nutrition==
A typical energy bar weighs between 30 and 50 grams and is likely to supply about 200–300 [[calorie]]s (840–1,300 [[joule]]s), 3–9 grams of [[fat]], 7–15 grams of [[protein]], and 20–40 grams of [[carbohydrate]]s — the three sources of [[energy]] in food.<ref>{{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}}</ref> In order to provide energy quickly, most of the carbohydrates are various types of [[Sugar|sugars]] like [[fructose]], [[glucose]], [[maltodextrin]] and others in various ratios, combined with complex carbohydrate sources, such as [[Oat|oats]] or [[barley]]. Proteins come mostly in the form of [[whey protein]].{{cn|date=February 2022}} Fats sources are often [[cocoa butter]] and [[Types of chocolate#Dark chocolate|dark chocolate]].{{cn|date=February 2022}}
