Beans Primer for Kidney Diets
Kidney, pinto, cranberry, black, and navy. What do these have in common? They are all types of beans! Beans, which are sometimes excluded from the kidney diet, are a valuable source of many nutrients, including fiber.
Fiber and Beans
It is important to include fiber in your diet. In fact, it is recommended that you get about 25 g of fiber daily. Beans contain from between 6 to 10 grams of fiber per 1/2 cup depending on the type 1.
Beans contain two types of fiber, soluble and insoluble. Soluble fiber helps capture cholesterol in the digestive tract. This cholesterol is then excreted instead of being absorbed. The other type of fiber, insoluble fiber, also provides health benefits. Insoluble fiber attracts water to the stool and can help keep you regular1.
Potassium and Beans
Beans are high in potassium, so you may be wondering how they fit into a kidney diet. Preparation is key. Soaking and cooking dried beans will help reduce potassium. To lower the potassium content, beans should be soaked in six cups of water for twelve hours and then cooked for 30 minutes using fresh water. If you are using a pressure cooker, beans should be cooked for 15 minutes2.
Phosphorus and Beans
Phosphorus is high in all types of beans. But, all the phosphorus in beans is not absorbed by our bodies. Phosphorus is not completely absorbed because it is bound to phytates in the beans.
Canned beans are actually lower in phosphorus and potassium compared to cooked dried beans. Canned beans may be used in place of dried beans to save preparation time. Beans should be rinsed and drained to remove some of the sodium. A half cup of drained and rinsed kidney beans contains about 200 mg potassium and 100 mg of phosphorus3.
