Health benefits of black beans
1. Protect against cancer
Recent research has shown that consuming black beans can lower the risk of breast, liver, colon, lung and prostate cancer. Black beans contain phytochemicals like flavonoids, tannins, phytic acid, triterpenes, and phytosterols that are responsible for their anti-cancer properties.
In one study, when researchers fed a diet containing black beans to rats, they showed significantly lowered colon cancer incidence and multiplicity (2).
The antioxidants found in black beans help combat free-radical damage. Studies have also shown that the high antioxidant content of these beans prevents DNA damage and gene mutation, which lowers the risk of developing cancerous cells (3).
2. Improve heart health
Turtle beans are packed with fiber, potassium, folate, vitamin B6, and phytonutrients, all of which help improve heart health.
Vitamin B6 and folate help prevent the accumulation of homocysteine in the body. Too much homocysteine in the body can damage blood vessels and lead to heart issues.
The high fiber content in black beans also helps lower the amount of cholesterol in the blood. Fiber helps to remove the toxins from the body, which keep arteries free of dangerous plaque build-up (6).
Turtle beans also contain quercetin and saponins, which help protect the heart. Quercetin helps reduce the risk of atherosclerosis and protect against the damage caused by LDL cholesterol.
Saponins also help lower blood lipid and cholesterol levels, and this protects the heart.
Black beans are rich in soluble fiber, magnesium, and potassium, all great nutrients for reducing blood pressure. Low sodium intake is also essential to maintain healthy levels of blood pressure, and black beans are naturally low in sodium.
If you buy canned black beans, make sure you choose a low sodium option.
4. Help prevent and manage diabetes
These beans are an excellent source of complex carbs like starch which does not cause sugar spikes. Eating the wrong type of carbs can lead to a sugar high, which is followed by a crash.
In the long term, this can lead to diabetes. Black beans are a great food to have for anyone who has formed a resistance to insulin, like people who have diabetes.
These beans are also high in fiber content, which makes it beneficial for individuals with type 1 diabetes. Consuming black beans also helps improve blood sugar levels, lipids and insulin levels in people with type 2 diabetes.
5. Improve digestive health
These beans are rich in dietary fiber which helps improve digestion by keeping the digestive tract clean. Fiber also helps keep the gut flora balanced, which helps promote digestive health. It also helps prevent constipation and irritable bowel syndrome.
According to a study published in The British Journal of Nutrition, black beans contain non-digestible fermentable components and phenolic compounds which demonstrate antioxidant and anti-inflammatory properties.
So, they help protect colon health and prevent colon cancer (7).
6. Improve bone health
Black beans contain essential nutrients like iron, phosphorus, calcium, magnesium, manganese, copper and zinc, which help build bone structure and strength.
Calcium and phosphorus help improve bone structure, while zinc helps in maintaining the strength and elasticity of bones and joints.
The high magnesium content in black beans is vital for over 300 enzymatic reactions in the body including metabolism. It is essential for improving bone health as well.
Black beans are a rich source of vegetarian protein. One cup of black beans provides 15 grams of protein. Protein is needed for many vital functions in the body. It helps build muscle and keep the body healthy.
A deficiency in protein can lead to fatigue, muscle weakness, cataracts, heart issues, and hormonal imbalance.
8. Helps with weight loss
Black or turtle beans are low in calories and rich in protein and dietary fiber, which is an excellent combination to have if you’re trying to lose weight.
High fiber foods help to keep you fuller for longer and hence reduce appetite. Many studies have shown that fiber-rich foods like black beans can decrease the risk of obesity, diabetes and heart disease.
9. Rich source of vitamins and minerals
These magical beans are packed with many vitamins and minerals like iron, magnesium, copper, folate, and phosphorus. These nutrients make black beans an excellent choice for vegetarians, who may be lacking these vitamins and minerals in their diet.
Folate helps the body to make new healthy cells. It is also essential for pregnant women to prevent congenital disabilities. Magnesium aids in the production and distribution of energy and synthesis of protein.
We need potassium for proper muscle, and nerve function and iron helps the body oxygenate itself.
10. Help prevent anemia
Anemia is a common, easily treated condition that occurs if you don’t have enough iron in your body to build healthy red cells (8). Iron deficiency anemia can cause fatigue, shortness of breath, chest pain and other symptoms.
These beans are rich in iron. One cup of black beans can take care of 20 percent of your daily requirement of iron. So, have more black beans to add more iron to your diet.
