A food pyramid or pyramid is a representation of the optimal number of

Swedish origin[]

Amid high . The pyramid competed with the National Board's "dietary circle," which KF saw as problematic for resembling a cake divided into seven slices, and for not indicating how much of each food should be eaten. While the Board distanced itself from the pyramid, KF continued to promote it.

Food pyramids were developed in other . The United States later developed its first food pyramid in 1992.

Food pyramid published by the WHO and FAO[]

The versus sugars in their natural form. Some food substances are singled out due to the impact on the target issues that the "pyramid" is meant to address. In a later revision, however, some recommendations are omitted as they automatically follow other recommendations while other sub-categories are added. The reports quoted here explain that where there is no stated lower limit in the table below, there is no requirement for that nutrient in the diet.

A "simplified" representation of the "Food Pyramid" from the 2002 Joint WHO/FAO Expert Consultation recommendations

Dietary factor	1989 WHO Study Group recommendations	2002 Joint WHO/FAO Expert Consultation recommendations
Total fat	15–30%	15–30%
Saturated fatty acids (SFAs)	0–10%	<10%
Polyunsaturated fatty acids (PUFAs)	3–7%	6–10%
n-6 PUFAs		5–8%
n-3 PUFAs		1–2%
Trans fatty acids		<1%
Monounsaturated fatty acids (MUFAs)		By difference
Total carbohydrate	55–75%	55–75%
Free sugars	0–10%	<10%
Complex carbohydrate	50–70%	No recommendation
Protein	10–15%	10–15%
Cholesterol	0–300 /day	< 300 mg/day
Sodium chloride (Sodium)	< 6 /day	< 5 g/day (< 2 g/day)
Fruits and vegetables	≥ 400 g/day	≥ 400 g/day
Pulses, nuts and seeds	≥ 30 g/day (as part of the 400 g of fruit and vegetables)
Total dietary fiber	27–40 g/day	From foods
NSP	16–24 g/day	From foods

All percentages are percentages of , not of weight or volume. To understand why, consider the determination of an amount of "10% free sugar" to include in a day's worth of calories. For the same amount of calories, free sugars take up less volume and weight, being refined and extracted from the competing carbohydrates in their natural form. In a similar manner, all the items are in competition for various categories of calories.

The representation as a pyramid is not precise, and involves variations due to the alternative percentages of different elements, but the main sections can be represented.

USDA food pyramid[]

History[]

.

The USDA food pyramid was created in 1992 and divided into six horizontal sections containing depictions of foods from each section's food group. It was updated in 2005 with colorful vertical wedges replacing the horizontal sections and renamed . MyPyramid was often displayed with the food images absent, creating a more abstract design. In an effort to restructure food nutrition guidelines, the USDA rolled out its new program in June 2011. My Plate is divided into four slightly different sized quadrants, with fruits and vegetables taking up half the space, and grains and protein making up the other half. The vegetables and grains portions are the largest of the four.

A modified food pyramid was proposed in 1999 for adults aged over 70.

Vegetables[]

A , but ingredients added in preparation can often add these.

Grains[]

These foods provide complex .

Fruits[]

In terms of food (rather than botany), -bearing parts of plants, or occasionally sweet parts of plants which do not bear seeds. These include .

Oils and sweets[]

A food pyramid's tip is the smallest part, so the fats and sweets in the top of the Food Pyramid should comprise the smallest percentage of the diet. The foods at the top of the food pyramid should be eaten sparingly because they provide calories, but not much in the way of nutrition. These foods include salad dressings, oils, cream, butter, margarine, sugars, soft drinks, candies, and sweet desserts.

Dairy[]

. However, many dairy products are high in saturated fat and cholesterol compared to vegetables, fruits and whole grains, which is why skimmed products are available as an alternative. Historically, adults were recommended to consume three cups of dairy products per day.

Meat and beans[]

.

The meat group is one of the major compacted food groups in the food guide pyramid. Since many of the same nutrients found in meat can also be found in foods like , beans, lentils, chick peas, nuts and other high-protein vegetables are also included in this group. The food guide pyramid suggests that adults eat 2–3 servings per day. One serving of meat is 4 oz (110 g), about the size of a deck of cards.
