TABLE iII-Advice on portions for consumers on "eatingfive portions of fruit and vegetables a day." (The term "serving spoonfiIl" has been used to emphasise that the amounts offfruit and vegetables are as served on to the plate, rather than raw ingredients) Food type Practical description of portion (approx 80 g) Examples Fruit: Very large fruit One large slice Melon, pineapple Large fruit One whole Apple, banana Medium fruit Two whole Plum, kiwi Berries Cupful Raspberries, grapes Stewed and Three serving spoonfuls Stewed apple, canned canned fruit peaches Dried fruit Half serving spoonful Apricots, raisins Fruit juice Full wine glass Orange juice, fresh and from concentrate Vegetables: Green vegetables Two serving Broccoli, spinach spoonfuls Root vegetables Two serving spoonfuls Carrots, parsnip Very small Three serving spoonfuls Peas, sweetcom vegetables Pulses and beans Two serving spoonfuls Baked beans, kidney beans Salad Bowlful Lettuce, tomatoHow much in a portion?Whether advice to "eat five a day" should refer to the number of occasions of eating fruit and vegetables or the number of portions is uncertain.To achieve the kind of dietary changes proposed in health strategies such as the Health of the Nation and The Scottish Diet advice needs to promote consumption of five "decent sized" servings or portions.A couple of slices of tomato in a sandwich or a few mushrooms in a chicken and mushroom pie should not count.Nutrition information which uses a mean portion size of around 80 g as a decent sized portion ties in well with average serving sizes used by households in Britain.20The main area of discrepancy is with salad foods: consumers and caterers should be told that it is necessary to eat a "bowlful" of salad to count as one portion.Table III uses this approach to show amounts which constitute a "portion" of fruit and vegetables.Supporting advice should explain that serving size should reflect age, sex, and activity and that active young men would be expected to eat larger portions.Similarly, small children can still aim to "eat at least five" but their portions may be smaller.I thank the policy unit of the Consumers' Association for supporting initial development work for this paper and for comments received from interested parties, particularly the Department of Health.A more detailed list is available on request for use in preparing photographs and illustrations of portion sizes and for interpreting dietary surveys.
