Consumption of grains by Americans is above recommendations

A bar chart showing the U.S. per capita consumption of grains in 1970 and 2014.

The 2015-2020 Dietary Guidelines for Americans recommend that people requiring 2,000 calories per day consume 6 ounce-equivalents of grains, half of which should be whole grains. An ounce equivalent of grains is generally equal to 1 slice of bread, 1 cup of ready-to-eat cereal, ½ cup of cooked rice, pasta, or cereal, 1 tortilla (6 inch diameter), or 1 pancake (5 inch diameter). According to ERS’s loss-adjusted food availability, Americans consumed an average of 6.7 ounce-equivalents of wheat flour, corn products, and other grains (rye flour, oat products, and barley products) per day in 2014. This is a 35-percent increase from 5.0 ounce-equivalents per person per day consumed in 1970. While wheat flour consumption grew by 23 percent, consumption of corn products grew by 202 percent, reflecting the growing popularity of corn-based foods, such as tortillas and chips, and the use of cornstarch in processed foods. Consumption of rye flour, oat products, and barley products totaled 0.21 ounce-equivalents per person per day in 1970, and fell to 0.16 ounce-equivalents in 2014. This chart appears in "U.S. Diets Still Out of Balance with Dietary Recommendations" in the July 2017 issue of ERS’s Amber Waves magazine.
