A food pyramid or diet pyramid is a pyramid-shaped diagram representing
the optimal number of servings to be eaten each day from each of the
basic food groups.
The first food pyramid was published in Sweden in 1974. The food
pyramid introduced by the United States Department of Agriculture in the
year 1992 was called the "Food Guide Pyramid". It was updated in 2005
and then replaced by MyPlate in 2011.
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.
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 MyPlate 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.
There are six basic food groups:
- Vegetables. A vegetable is a part of a plant consumed by humans that is generally savory but is not sweet. A vegetable is not considered a grain, fruit, nut, spice, or herb. For example, the stem, root, flower, etc., may be eaten as vegetables. Vegetables contain many vitamins and minerals; however, different vegetables contain different spreads, so it is important to eat a wide variety of types. For example, green vegetables typically contain vitamin A, dark orange and dark green vegetables contain vitamin C, and vegetables like broccoli and related plants contain iron and calcium. Vegetables are very low in fats and calories, but ingredients added in preparation can often add these.
- Grains. These foods provide complex carbohydrates, which are an important source of energy, especially for a low-fat meal plan.
- Fruits. In terms of food (rather than botany), fruits are the sweet-tasting seed-bearing parts of plants, or occasionally sweet parts of plants which do not bear seeds. These include apples, oranges, grapes, bananas, etc. Fruits are low in calories and fat and are a source of natural sugars, fiber and vitamins. Processing fruits when canning or making into juices may add sugars and remove nutrients. The fruit food group is sometimes combined with the vegetable food group. Note that a massive number of different plant species produce seed pods which are considered fruits in botany, and there are a number of botanical fruits which are conventionally not considered fruits in cuisine because they lack the characteristic sweet taste, e.g., tomatoes or avocados.
- 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 your daily 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. Dairy products are produced from the milk of mammals, usually but not exclusively cattle. They include milk, yogurt and cheese. Milk and its derivative products are a rich source of dietary calcium and also provide protein, phosphorus, vitamin A, and vitamin D. 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. More recently, evidence is mounting that dairy products have greater levels of negative effects on health than previously thought and confer fewer benefits. For example, recent research has shown that dairy products are not related to stronger bones or less fractures.
- Meat and beans. Meat is the tissue‚ usually muscle‚ of an animal consumed by humans. Since most parts of many animals are edible, there is a vast variety of meats. Meat is a major source of protein, as well as iron, zinc, and vitamin B12. Meats, poultry, and fish include beef, chicken, pork, salmon, tuna, shrimp, and eggs. The meat group is one of the major compacted food groups in the food guide pyramid. Many of the same nutrients found in meat can also be found in foods like eggs, dry beans, and nuts, such foods are typically placed in the same category as meats, as meat alternatives. These include tofu, products that resemble meat or fish but are made with soy, eggs, and cheeses.
