Start with the audience and the source
A food guide may use a plate, a pyramid or another visual model. The illustration is only part of the guidance. The accompanying text identifies the intended population, food groups and practical messages.
FAO's country collection brings together national guidelines and links to further information. Countries adapt guidance to their food supply, dietary habits and nutrition needs. Inclusion in the collection does not mean that FAO has endorsed every country's development process. Find national guidelines through FAO.
Before comparing two guides, find the issuing authority and the current publication. A translated summary can help you navigate, but the original document is the place to check definitions and exceptions.
Compare like with like
Use a short comparison table rather than comparing the pictures alone:
| Question | What to note |
|---|---|
| Who is the guide for? | Age range, population and any separate guidance for specific needs. |
| How are foods grouped? | Which foods are combined, separated or illustrated as examples. |
| What does the visual represent? | A meal, a day, a longer-term pattern or another stated basis. |
| How are amounts expressed? | Portions, frequencies, proportions and the definitions behind them. |
| What supports the advice? | Scientific reports, methods documents and the date of the guidance. |
Differences are useful questions for investigation. They are not, by themselves, evidence that one country has ignored nutrition science.
Two national examples
The UK's Eatwell Guide publication page provides the food model alongside supporting documents, including government dietary recommendations and reports explaining the model. For a teaching session, this lets you distinguish the public-facing illustration from the technical material behind it.
The Swiss Federal Food Safety and Veterinary Office publishes dietary recommendations for adults aged 18–65. Its food pyramid is accompanied by practical advice about food groups, health and sustainability. The stated age range matters: it should remain visible when the guide is discussed or reproduced.
A useful comparison exercise is to choose one food group and describe how each source presents it. Record the wording, intended audience and unit of advice. Avoid converting a visual proportion into a precise daily quantity unless the issuing body provides that interpretation.
Use guidance in teaching and professional work
When preparing educational material, link to the national authority, name the version and explain the intended use. Keep examples relevant to the audience's food culture and circumstances. If you adapt a picture or translate a message, check the publisher's reproduction conditions and make the adaptation clear.
Food guidance and nutrient reference values serve related but different purposes. Use our reference values guide when your question concerns a nutrient figure. For questions about environmental, economic and cultural dimensions, continue to sustainable healthy diets.
