According to the loss-adjusted food availability data compiled by the USDA Economic Research Service (ERS), Americans consumed 52.3 pounds of potatoes and 31.1 pounds of tomatoes per person in 2012. Half of the per capita potato consumption was fresh, while 59 percent of the tomato consumption was canned. French fries and pizza contributed to the high consumption of these two vegetables.
At 8.1 pounds per person, onions were the next most highly consumed vegetable among Americans in 2012. By accounting for food spoilage, plate waste and other losses, loss-adjusted food availability data more closely approximate actual per capita consumption than do non-adjusted food availability data. Additional per capita estimates of the types and amounts of foods consumed by Americans can be accessed at USDA/ERS.
