Most American diets do not meet Federal Food Guide Pyramid dietary recommendations. On average, people consume too many servings of added fats and sugars and too few servings of fruits, vegetables, dairy products, lean meats, and foods made from whole grains compared with a reference set of Food Guide Pyramid serving recommendations appropriate to the age and gender composition of the U.S. population. In addition, while the healthfulness of diets has improved over time, the pace of improvement has been uneven. For example, while Americans consumed record amounts of fruits and vegetables in 1996, consumption of caloric sweeteners also reached a 27-year high. This report is the first dietary assessment to use ERSís time-series food supply data to compare average diets with Federal dietary recommendations depicted in the Food Guide Pyramid. Food Guide Pyramid servings were estimated for more than 250 agricultural commodities for 1970-96. New techniques were developed to adjust the data for food spoilage and other losses accumulated throughout the marketing system and the home.
