Things worth knowing

• One cup of cooked kidney beans (177 g) has about 225 kcal / 941 kJ, 15 g of protein and 13 g of fibre, nearly half the 28 g Daily Value.
• The same cup gives around 230 µg of folate, about 58% of the Daily Value, and 5.2 mg of iron.
• Canned kidney beans, drained, are about the same at 124 kcal per 100 g, but carry around 231 mg of sodium per 100 g unless rinsed or bought no-salt-added.
• Dried red kidney beans must be soaked and boiled thoroughly before eating; undercooked beans contain a natural lectin that can cause severe stomach upset.
