Vitamin C in specific foods

How this list is built. Values are from USDA FoodData Central (SR Legacy, with Foundation Foods analytical updates where available). The pool is 1,677 whole foods: fruits, vegetables, legumes, nuts and seeds, grains, fish, meat, poultry, dairy and eggs. Spices, herbs, baby foods, powders, flours, dried and freeze-dried items, juices, processed meats, organ meats other than liver and uncommon foods are excluded; meats, fish, grains and legumes are ranked cooked. Each food family appears once and no single animal or plant fills more than six places. Ranking is by amount per serving; the per-100 g column is shown for reference. A food that USDA has not analysed for vitamin C is left out rather than counted as zero. Full methodology.
