How the numbers are taken. Amounts are per 100 g of the edible part, from USDA FoodData Central (SR Legacy, public domain), in the state named — raw, boiled, roasted and so on. Percentages use the FDA Daily Values for adults and children aged 4 and over, set around a 2,000-calorie diet; your own needs can be different. This site compares amounts — it does not give diet or medical advice. Sources and limits.
