Description of the 1992 Food Pyramid
Released in 1992, the food pyramid suggested how much of each food category one should eat each day. The food guide pyramid replaced the four food groups. On April 19, 2005, the USDA released the food guide pyramid's successor, MyPyramid.
The original food guiding pyramid, informally known as the food pyramid, was a nutrition guide created by the USDA.
This initial pyramid became famous throughout the world, and was, in some way, an American icon. One issue that this pyramid had was that it was seen as too rigid; the new pyramid relects the idea that a diet should be shaped according to an individual's needs. The old pyramid allowed to consume the foods within a certain range of servings, but gave no hint on how to interpret that choice.
In general terms the food guide pyramid recommends the following intake of different food groups each day, although exact amounts of calorie intake depends on sex, age, and lifestyle:
- 3-5 servings a day of vegetables, especially green, leafy vegetables;
- 2-4 servings of fruits a day;
- occasional use of fats, oils, and sweets; or can be 2-4 times in two months. (7 tsp Oil per day)

The Harvard School of Public Health proposes some information about a different pyramid. They include calcium and multi-vitamin supplements as well as moderate amounts of alcohol.
