Vitamin B12 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 B12 is left out rather than counted as zero. Full methodology.
