Food guides are graphic representations of all or some of the messages of the dietary guidelines. They typically represent the recommended food groups in the suggested proportions for a good diet. Messages about lifestyle, such as recommendations of regular physical activity and warnings related to alcohol consumption may also be displayed. The most common example of food guides are in the shape of a food pyramid and food plate. However, many countries choose a food guide that is culturally specific for the population of each country and may become an important symbol in a nation's nutrition communication and education strategy.

Some countries have adapted their food guide for different population groups, such as indigenous peoples.
