We hear about the difference between complex and simple carbohydrates, their food sources, their function in the body and the energy they release. We are advised to get 55% of our calories from carbohydrate rich foods, particularly complex carbohydrates such as wholegrains, wholemeal bread, rice and potatoes. The links between simple carbohydrates, or sugar, and the risk of tooth decay, heart disease and weight gain are explained. The idea of balancing energy in and energy out is highlighted. Presenter Stefan Gates uses a 'sugar shotgun' to illustrate how energy is released from food and creates heat. This clip is from the BBC series Gastro Lab. Stars of stage, sport and screen reveal the foods that keep them at the top of their profession, while presenter Stefan Gates explores the world of nutrition with experiments that will make tongues tingle, stomachs churn and hair stand on end.

GCSE / KS3 Biology / KS3 and 2nd Level Food Technology Pupils can be asked to compare the amount of calories per 100g or per portion found in a selection of carbohydrate-based foods, by examining food labels or using nutritional analysis. These foods can be placed in rank order and evaluated as to which would be the best to eat before a marathon. This clip will be relevant for teaching Biology and Food Technology at Key Stages 2, 3 and 4 in England, Wales and Northern Ireland, and 2nd , 3rd and 4th Level and National 4 and 5 in Scotland. ===================== For more clips from other subjects at the BBC Teach YouTube channel: http://www.youtube.com/bbcteach More from BBC Learning Zone: http://www.bbc.co.uk/learningzone More resources from BBC Bitesize: http://www.bbc.co.uk/education ===================== Subscribe to create your own customised playlists, and get notified about our latest clips.
