Question to the Department for Education:

To ask the Secretary of State for Education, what assessment she has made of the effect of the consumption of energy drinks by under-18s on their ability to concentrate at school.

The department does not hold information on the number of schools that have banned students from consuming energy drinks on school premises.

The new standards for school food came into force on 1 January 2015. The School Food Standards define the foods and drinks that must be provided, which are restricted, and those which must not be provided. They apply to all food and drink provided to pupils on and off school premises and during an extended school day (up to 6pm), including school trips, breakfast clubs, tuck shops, mid-morning break, vending and after school clubs.

The only drinks permitted are: Plain water (still or carbonated); lower fat milk or lactose reduced milk; fruit or vegetable juice (max 150mls); plain soya, rice or oat drinks enriched with calcium; plain fermented milk (e.g. yoghurt) drinks; combinations of fruit juice and lower fat milk or plain yoghurt, plain soya, rice or oat drinks enriched with calcium; cocoa and lower fat milk; flavoured lower fat milk, all with less than 5% added sugars or honey; tea, coffee, hot chocolate

Combination drinks are limited to a portion size of 330mls. They may contain added vitamins or minerals, and no more than 150mls of fruit or vegetable juice. Fruit or vegetable juice combination drinks must be at least 45% fruit or vegetable juice.
