Health Benefits of Black Beans
Black beans were first domesticated thousands of years ago in Peru, and quickly became a staple of the South American diet. They first came to Europe when explorers came home with them in the 1500s.
They are very high in fiber, folate, protein, and antioxidants, along with numerous other vitamins and minerals. Black beans make a complete protein when paired with brown rice, which is often why they are so commonly included in a vegetarian diet.
Blood Sugar Regulation – With a low glycemic index, beans contain a beautiful blend of complex carbohydrates and protein. Because of this, beans are digested slowly, which helps keep blood glucose stable, and may curtail fatigue and irritability.
1. Cancer Prevention
Considering that black beans contain at least 8 different flavonoids with enormous antioxidant potential, and their high content of phytochemicals, it’s hardly surprising that studies have connected black bean consumption with reduced risk of certain cancers. Recent studies have suggested considerable effectiveness against colon adenoma, a non-cancerous tumor that can progress into colon cancer.
2. Cardiovascular Health
Black beans are abundant in soluble fiber, which is specifically the type of fiber that has been found very helpful in lowering blood cholesterol levels. Lowered risks of coronary heart disease and heart attack have both been associated with increased consumption of soluble fiber, particularly from legumes.
Black beans also contain a wide variety of both antioxidant and anti-inflammatory properties, which combat cardiovascular disease. Antioxidant and anti-inflammatory protection is particularly important for the cardiovascular system. When blood vessels are exposed to excessive oxidative stress or inflammation, risk for disease development is considerably higher. The prevention of oxidative stress and inflammation lowers risk of acquiring most cardiovascular diseases. They are also high in folate and magnesium, both nutrients highly associated with preservation of cardiovascular health, and the antioxidant minerals zinc and manganese.
3. Digestive Tract Benefits
The high quantity of both protein and fiber in black beans help to move food through the stomach to the large intestine at a healthier pace. This keeps any one part of the digestive tract from having to work too hard and supports the ideal balance of chemicals and populations of microorganisms required for a healthy digestive system.
4. Low In Fat
Most beans are about 2 to 3 percent fat, and contain no cholesterol, unless they’re processed or prepared with other ingredients, such as lard. (Check labels to see what else may be in the package or can.)
5. Nervous System Health
Folate, or vitamin B6, is particularly abundant in black beans. The nervous system relies on folate to produce the amino acids it needs to function. For pregnant women a deficiency in folate can cause the improper development of the fetus’s brain and spinal cord. The high iron content of black beans is also particularly beneficial to pregnant women.
6. Other benefits
They are convenient. Canned, frozen or dry, beans are a breeze to purchase, prepare, and store. Beans are also the least expensive source of protein.
The Dietary Guidelines for Americans say we should be eating more plant proteins. About 1/2 cup of beans provides 7 grams of protein, the same amount as in 1 ounce of chicken, meat or fish. Vegetarians, vegans and individuals who seldom eat meat, poultry, or fish could count on beans as an alternative choice.
8. Rich in Molybdenum
Black beans are an extremely rich source of the trace mineral molybdenum. Molybdenum serves the useful purpose of breaking down and detoxifying sulfites found in foods like salads and wines. Many people are sensitive to sulfites, and may they cause rapid heartbeat, headache or disorientation when consumed. Studies also suggest that molybdenum deficiencies can result in impotence in older men.
9. Weight loss
Because beans are metabolized more slowly than other complex carbohydrates, they may aid in weight loss by keeping us feeling full without being excessively high in calories.
