This study evaluated the daily per drinker intakes of total phenolics, total flavonoids, and antioxidants from coffee in the Korean diet. Four types of coffee (instant coffee, decaffeinated instant coffee, roasted coffee, and coffee mix) were selected and analyzed. Based on the Korea National Health and Nutrition Examination Survey in 2012, the daily intakes per coffee drinker were estimated to be 348.6 mg gallic acid equivalents for phenolics, 222.5 mg catechin equivalents for flavonoids, and 370.8 mg vitamin C equivalents (DPPH assay) or 546.7 mg vitamin C equivalents (ABTS assay) for antioxidants. Men had higher intakes of instant coffee and coffee mix, while women had a higher intake of roasted coffee. Regarding age categories, over 58% of the coffee consumers were 30–59 years old. This study revealed that, in Korea, approximately half of the people drank about 1.4 cups of roasted coffee or 2.0 cups of instant coffee every day.
