A dietary management system first developed in the USA for diabetics. The lists consist of six types of food that have been grouped together because they have a similar calorific content and similar composition of carbohydrates, fats, and proteins. The groups are:• milk and milk products (skimmed milk recommended)• vegetables• fruit• bread (starchy foods)• meat (lean, low fat products recommended)• fat.Each group contains lists of foods and the amounts which provide equivalent energy and macronutrients. For example, one teaspoon of oil is equivalent in fat and energy content to one rasher of bacon; and half a banana has a similar content of energy, carbohydrate, protein, and fat, to one small apple. Nutritionally balanced, calorie-controlled diets can be constructed on the basis of the dietary exchange system. Consequently, the lists are used by a wide range of people to plan a structured diet for weight control. In the UK, special carbohydrate exchange lists are used by some people with diabetes, and protein exchange lists by people who need to restrict their protein intake (e.g. those people with kidney disease need to keep their protein intake as low as possible but still obtain adequate amounts of all the essential amino acids).
