It set up a subgroup to advise on simple and practical messages on the consumption of these foods. This paper reflects the conclusions of that subgroup on fruit and vegetables.

No universally accepted convention exists on which foods should be included in health advice on fruit and vegetables.1 When different definitions are used misleading conclusions can be drawn about current levels of fruit and vegetable consumption, and the interpretation of diretary surveys can be conflicting. Lack of clarity over the status of the more controversial foods such as dried fruit or pulses can lead to confusion and uncertainty among consumers. Disagreement among academics and health professionals over these issues lends further weight to the public perception that …
