Annex four - Examples of foods in current sets of dietary guidelines and food guides(1)
1 The following examples illustrate how foods and food groups have been incorporated into dietary guidelines in selected countries. They also indicate the types of food guides that have been developed as visual aids and teaching tools to help implement the guidelines. The inclusion of these guidelines does not mean they are being endorsed or promoted as "recommended" dietary guidelines or food guides, especially since some of the scientific assumption underlying some statements have been overtaken by more recent research and knowledge.
A number of countries and organizations have developed dietary guidelines. While the consultation did not review them, examples of foods that feature in the current sets of dietary guidelines are provided in Table 8 (1) (the numbers in the set column refer to specific food guidelines). For example, in the Australian set guidelines 2, 6, 9 and 10 name foods, while guidelines 1, 3, 4, 5, 7 and 8 (not shown in the table) are expressed in other ways, without naming foods. The latter category predominates.
The foods that appear in these guidelines are usually large groups, e.g. vegetables, fruits, cereals, meat; but in some cases they are more specific, e.g. citrus fruits, bread, fatty fish, rice. A few guidelines specify processing or lack of processing (e.g. whole grain, smoked, full cream, saltcured, fresh).
Example 7(Fiji), is used throughout the South Pacific and in a number of African and other countries. It may have originated in the UK in World War 11. This three-food-groups system has one group of foods said to provide energy, another protein, and a third consisting of fruits and vegetables (in some sets termed as "health" or "selective" foods).
Example 5, is a four-food-group system proposed by Abrahamsson (2) for developing countries, especially for feeding children. It gives pride of place to the country's staple, which not only provides energy but also protein and other nutrients. For good nutrition it needs to be supplemented with foods from three groups: vegetables and fruits (for vitamins A, B and C), proteinrich food (especially for young children) and extra energy (most conveniently as some form of oil).
Example 4, in the Caribbean the food guide had more groupssix formerly and now seven. The current food guide strongly emphasizes fruit and vegetables, and includes, but de-emphasizes, fats and sugar.
In industrialized countries there are mostly four, five or three food groups. The foods that differ most between country systems are:
Milk, which has its own group in Canada (3), USA (15), Australia (1), New Zealand (12), Denmark (6), Finland (8), Germany (9) and the UK (14), but not in the Netherlands (11) or Sweden (13). In the Netherlands, milk is grouped with other animal foods; in Sweden, it is grouped with cereal foods and potatoes as the basal diet in the bottom layer of the pyramid.
Potatoes appear as a special food group in Finland (8). In some countries they are grouped with green vegetables (2) (3) (12). In other countries they are grouped with cereals (6) (11) (13) (14).
Fats & oils do not appear in Canada (3). In some countries they appear as a small ("eat sparingly") separate group (1) (6) (8) (9) (11). In other countries they are combined with sugar in a small ("eat sparingly") group (8) (12) (14).
Legumes appear with the meat group in some countries (1) (3) (14) (15), usually described as "dry legumes". In other countries they may be grouped with green vegetables.
Food groups are also being used to represent advice on vegetarian diets, therapeutic diets for diabetes mellitus, for lowering plasma LDL-cholesterol, and for describing an idealized Mediterranean diet.
It is much easier to illustrate unpackaged, single foods. Some countries have made suggestions where mixed dishes fit in their food group systems, e.g. in a reserve comprehensive list.
Note that these food guides in the table do not express all the dietary guidelines of the corresponding country. "Eat less or little fat" can be conveyed by having a fats and oils group and showing it very small (1) (11). In the US food pyramid fats are shown as small white circles against a black background. It remains to be seen how efficiently this pictorial symbolism can convey the message. It has proved very difficult to convey in visual form: "Balance energy intake against expenditure; avoid overweight/obesity" and "if you drink alcohol, do so in moderation".
In countries, the individual foods which are generally available and which educators wish to emphasize are mentioned in the text or shown in visual material. Preferred forms of the food can be described in accompanying text, e.g. Iow-fat meat, fatty fish, whole-grain cereals, etc.
The main forms in which dietary guidelines have been expressed as food groups are assembled in Table 10.

Table 10: Visual presentation of food guides related to dietary guidelines
1. Have a mixture of brief text with illustrations of major individual foods, with a spreadsheet for each food group (e.g. 'Eat well ... live well' by Guild of Food Writers and Coronary Prevention Group, UK, 1991)
2. Several food groups, with examples illustrated in each. Each group within the same sized rectangle (e.g. Australian posters of the late 1970s, with 5 groups; South Pacific Commission posters with 3 groups; UK World War II material).
3. Several food groups represented by rectangles, cubes or squares of different sizes (e.g. 'Are you overweight?' Australia 1985).
4. Steps or piles of blocks of different heights (e.g. New Zealand). Each block the same size. Like building blocks, these can convey servingscereals 5 blocks piled up (= serves), vegetables 4, fruits 3, dairy 2 and meat or alternative 1 block serving.
5. Food circle, with food groups each the same sectoral size (e.g. Sweden food circle has 7 sectors of equal size).
6. Food circle with sectors of different area, typically largest for cereals and vegetable/fruit groups, smallest for fat (e.g. Netherlands Gezonde voeding met de maaltijdschiff, 1382; Finland has 6 sectors of different areas; Caribbean has 6 (old) or 7 (new)).
7. Circle with sectors for food groups of different area (narrow for fats) but also outer band of more processed products in each sector (group), with more fat, salt or sugar, so less recommended than the central area (inner circle) of unprocessed foods (e.g. South Australia 'Target on Healthy Eating').
8. The health food plate, which is a food circle, with sectors of different sizes, each illustrating major foods of the group, but the circle is seen as if tilted so drawn as an ellipse. It looks like a plate with a knife on one side and a fork on the other (UK Food Guide, 1994).
9. Triangle (some of these called a pyramid but drawn as 2-dimensional shape). Food groups that should tee eaten least are at the top; staple foods that should be eaten most are across the broad base of the triangle (e.g. Sweden 1977, USDA new food guide "pyramid" 1993; K. Baghurst (Australia) 1,2,3,4,5 + nutrition plan).
Pennington (1981) first suggested that the triangle or pyramid should be upside down, with the food group you should eat least of at the apex and below the other groups.
10. Pyramid, which shows different groups on two faces (e.g. Australian Nutrition Foundation from early 1980s; New Zealand National Heart Foundation).
11. Quarter rainbow, with 4 quadrants, the innermost one having the smallest area (so eat least) (e.g. Canada's Food Guide, 1992).
12. Traffic light: be careful with foods in red group; eat foods in orange group in moderation; eat as much as you like of foods in the green group (used especially for obesity and diabetic diets, e.g. UK Health Education Council, 1981).
