What the National Heart Forum says:
There is no universally accepted definition of junk food but broadly it can be defined as 'non-nutritious food'. It provides calories or 'fuel' for the body to fill children up but has few health promoting nutrients such as protein, vitamins and minerals.
It is food that provides 'empty calories' and has high concentrations of refined sugars, fat, salt, colourings, preservatives, artificial flavourings and artificial sweeteners. Things that eaten in excess can prove detrimental to health at any age.
However, it is not necessarily harmful to eat junk food occasionally and in moderation.
What the Oxford English dictionary says:
Junk food (noun): Food with little nutritional value.

Revision of school food guidelines eagerly awaited
Hungry for success, a report full of recommendations on School meals in Scotland, is considered by public health professionals to be the gold standard for School lunches as they are nutrient, rather than food based. The guidelines for England are currently being revised by the Caroline Walker Trust and due out summer 2005.
