Black Beans: Rich in Iron

Black beans are a high-iron food. They are tasty and versatile in cooking. The primary issue to keep in mind with black beans is that they contain mineral inhibitors that will reduce your ability to absorb all of the iron in them. You will not benefit from all of the iron indicated on the label unless you employ some strategies in your kitchen to reduce the iron inhibitors. These strategies will reduce iron inhibitors by half or more and will increase your digestion of the iron in the black beans. The primary strategy with any bean is to soak them in warm water overnight in a warm spot. We usually start with beans and near-boiling water in a stainless steel bowl and place it in a warm spot in our house overnight with a tea towel on top. The towel keeps out unwanted bugs, though they may help with the iron content. When you are ready to cook them, simply strain off the soaking water and add new water to cook them in. Note that they will need half or less the water that your recipe calls for because they will have been soaked. We like to cover them with water.
