Black bean
What it is
Black beans are beans eaten as a whole food. The selected USDA record describes mature beans that have been boiled without added salt, rather than dry beans, sprouts or a seasoned canned dish.
What it does
Each 100 g cooked provides 8.86 g of protein, 8.7 g of fiber and 149 micrograms of naturally occurring folate. Folate supports DNA production and cell division.
Research context and ingredient forms
The low sodium in this reference applies to the unsalted preparation. It cannot predict the sodium in canned beans, restaurant beans or beans cooked in salted stock.
Using this information
For canned beans, use the can label and note whether the serving includes liquid. When comparing a drained portion with this table, use the weight of the beans you actually eat.
