“Research has shown that consuming cooked black beans leads to lowered risk and incidence of breast, colon, liver, lung, and prostate cancers.” Scientists haven’t figured out the exact mechanism, but they suspect that it is the phytochemicals that protect the body from cancer. Black beans are some of the most phytonutrient concentrated foods on the planet.
Recent research has also shown them to lower the risk of Type II diabetes, cardiovascular disease, as well as cancer.
In the nation of Brazil black beans have been given an exclusive place on the Food Pyramid and recommends that its citizens eat half a cup of beans per day.
