English: Averages (%) of foods containing appropriate copper levels (to achieve adequate copper intake) based on the proposed method in food groups. All high copper (excellent source of copper) and copper source (good source of copper) foods, excluding high copper and copper source baby foods, are based on the reference energy intake of 2,000 kcal for adults and children aged 4 years and older. High copper and copper source baby foods are based on the reference energy intake of 1,000 kcal for children 1 through 3 years of age.

About 97% of foods contained copper. On the basis of the proposed method, the average (%) of foods containing appropriate copper levels in food groups was 41.24%, of which 23.92% was the average of copper source (good source of copper) foods, and 17.32% was the average of high copper (excellent source of copper) foods. Legumes and legume products with 95.3%, nut and seed products with 91.85%, baby foods with 87.64%, lamb, veal, and game products with 69.2%, breakfast cereals with 58.47%, and cereal grains and pasta with 55.8% had the highest averages of foods containing appropriate copper levels. Foods containing appropriate copper levels were found in all food groups, excluding fats and oils and spices and herbs. Foods containing appropriate copper levels included foods of plant and animal origin. However, few numbers of foods containing appropriate copper levels were copper-fortified foods.
