Kidney bean
What it is
Kidney beans are whole beans eaten after proper cooking. The selected profile is red mature kidney beans boiled without salt, rather than dry seeds or canned beans in sauce.
What it does
The cooked reference contains 8.67 g of protein, 7.4 g of fiber and 130 micrograms of folate per 100 g. Folate participates in DNA synthesis and cell division.
Research context and ingredient forms
This is a cooked-food nutrition record. It cannot be used to infer that raw or merely soaked kidney beans are safe to eat, and it does not describe a specific canned product.
Using this information
Choose a reference that matches cooked beans, drained canned beans or beans with their liquid. Keep chili, sauce and added meat separate when calculating a meal.
Considerations
Raw or undercooked kidney beans can cause illness from their lectin content. Follow an appropriate boiling preparation method; do not rely on low-temperature slow cooking alone for dried kidney beans.
