A food guide pyramid is a pyramid shaped guide of healthy foods divided into sections to show the recommended intake for each food group. 25 countries and organizations around the world have a food pyramid. This video discusses two of them - the US Department of Agriculture and the Canada Food Guide.

The US Department of Agriculture and Health Canada both have a visual guide to meal planning that differs in their representation.
The old 2005 US version is a pyramid shape with the largest group (carbohydrates like bread, cereal and pasta) is at the bottom and the smallest group (fats and oils) is at the top. The size of the group indicates how much you should eat of each. The diagram is labelled with the number of servings of each as a range. 6-11 servings of breads for example. The range is caused by the numbers having to cover all age groups in one diagram. A separate document is used to show the amount of servings for different groups.
In 2011 the figure changed because this one was too abstract for people to understand. The new one is still the same shape but is horizontal for each group. It lists servings based on an 1800 calorie diet with an example of the serving size to eat.
The Canadian Food Guide version is quite different. The table is drawn with horizontal areas for each food group with an example of the quantity of food to eat as one serving for a number of foods in each. ½ cup of vegetables for example is one serving in that group.
The first part of the table shows the number of servings recommended in the different age groups. Children age 4-8 for example should eat 5 servings of vegetables and fruit,
4 servings of grain products, 2 servings of milk and 1 serving of meat.
The more comprehensive guide is the Canadian chart because it gives the daily recommended number of servings per day for all age groups and gives examples of what one serving would be.
