Black Beans: The Blacker the Skin – the Healthier the Bean
Black beans are a part of the popular legume family of plants. As many other types of beans, they originated from the Central and South America and have been used in Latin-American countries for hundreds of years. In the fifteenth century Spanish explorers brought black beans to Europe, where they became popular due to some of their special properties:
- They are easy to grow
- They have long-term storage life
- They have a rich flavor similar to that of mushrooms.
The most distinct feature of black beans is their shiny shell-like appearance. This is also why they are sometimes called turtle beans.
Health Benefits of Black Beans
The saying “the blacker the skin – the healthier the bean” turns out to be 100% true in relation to these beans. To a great extent, their healthful qualities are accounted for a rich content of flavonoids with strong antioxidant properties. These substances are responsible for the black color of the beans’ skin. Additionally, black beans are packed with minerals, protein, fiber, and certain vitamins. This makes them one of the healthiest foods in the world. This legume helps with prevention and treatment of a number of serious ailments, such as:
- Heart disease.
Numerous studies have shown that the consumption of black beans decreases the risk of coronary heart disease as well as stroke. This fact is explained by their high content of soluble fiber. This is the type of fiber that lowers the cholesterol levels. In addition, the skin of black turtle beans provides us with important flavonoids. Flavonoids are potent antioxidants, and, therefore, fight the heart disease, which is often caused by the blood and vessels suffering from oxidative stress or inflammation. Black beans also contain antioxidant minerals such as magnesium, manganese, and zinc. Magnesium is especially important in maintaining the health of the veins and arteries as well as reducing high blood pressure.
Inflammation, as well as chronic excessive oxidative stress, is among the most probable causes of many types of cancer. It’s clear that the more antioxidant and anti-inflammatory elements there are in your body, the smaller is the risk of cancer. There have been a few studies of anti-cancer properties of black beans that indicate the ability of to these beans stop the development of several types of this disease, colon cancer, in particular.
The combination of high amounts of protein and fiber in black turtle beans helps support proper blood sugar levels. Additionally, research indicates that black beans can inhibit the activity of alpha-amylase enzymes that are responsible for breaking down starch into sugar. Reducing the speed of this process results in the reduction of the sugar release from starches found in foods.
High content of minerals such as phosphorus, calcium, magnesium, manganese, and molybdenum helps maintain strength and elasticity of bones as well as joints and prevent osteoporosis.
- Digestive disorders.
Studies have revealed the fact that black beans have the largest content of indigestible fracture among all the other beans and lentils. They contain the best mix of substances that are extremely beneficial for healthful bacteria in the colon.

How to Buy and Store Black Beans
Black beans are sold in dried or precooked – canned or frozen – forms. Dried beans are more cost effective. They are usually sold in pre-packaged containers or in bulk. When buying dried black beans, make sure they aren’t moist, damaged by insects, or cracked.
Dried beans should be stored in an airtight container. Keep them in a dark, cool, and dry place. Use them within one year. Cooked black beans will stay fresh for three days if they are kept in a covered container inside a fridge.
How to Soak Black Beans
- Boil the beans for two minutes. Take the saucepan from the heat and let them stay for two hours.
- Soak the beans in water for eight hours or overnight (but not more than for twelve hours). Place them in the fridge to prevent fermentation. Drain the water and rinse the beans before cooking.
It should be mentioned that soaking is necessary to clean the beans from certain chemical substances that can block important nutrients. Soaking increases mineral absorption and makes black beans easier to digest.
Fermented Black Beans
