Black Beans Nutrition Facts

A 100g of black beans nutrition facts are as follows (3): 

  • Calories: 132
  • Protein: 8.9 grams
  • Carbs: 24 grams
  • Fiber: 8.7 grams 
  • Fat: 0.5 grams
  • Sugar: 0.3 milligrams
  • Sodium: 1 milligram
  • Potassium: 355 milligrams

Black beans also contain iron, calcium, vitamin A, thiamin, magnesium, and manganese. They are also a good source of folate which helps produce red blood cells and prevent neural tube defects during pregnancy. To increase the absorption of iron, eat black beans together with vitamin C-rich foods such as tomatoes and vegetables.

The glycemic index of black beans is moderately low. This means that you can enjoy them without worrying that they will cause a spike in your blood sugar. When soaked and then boiled, the glycemic index is about 20. If you use a pressure cooker to prepare black beans or eat canned beans, the glycemic index is 30 (8).

Most of the very little fat in black beans is monounsaturated, polyunsaturated, and omega-3 fatty acids. These beans have no trans fats and contain very little saturated fats. So, even on a weight loss diet, you can still enjoy black beans.

Benefits Of Black Beans

Black beans are a source of many minerals, vitamins, and antioxidants, all of which help promote good health. Below are the black beans benefits and side effects:

Source Of Plant-Based Protein

Black beans are an excellent protein source. They are also rich in iron and other minerals. So, vegetarians and vegans who don’t consume animal protein may benefit from eating turtle beans.

Protein helps build tissues and muscle, repair damaged cells and act as enzymes or carriers. Protein also has the highest thermic effect of food (TEF) of 15 to 30%, while TEF of carbs is 5 to 10%. This means more energy is expended during the digestion, absorption, transport, and storage of protein compared to carbs and fats. Protein is also the most filling macronutrient (1).

Reduces Risk Of Diabetes

High-fiber foods help in the management of diabetes (10). 

Research shows that individuals with type 1 diabetes who eat diets rich in fiber have improved blood glucose levels. Those with type 2 diabetes also benefit from high fiber diets. A 2017 study sought to find out the glycemic response when black beans and chickpeas were added to white rice. At the end of the study, it was concluded that a combination of black beans, chickpeas, and rice improves glycemic response compared with rice alone (9).

Helps Build Healthy Bones

The calcium, potassium, phosphorus, magnesium, and zinc in black beans are all important for healthy bones. Osteoporosis and low bone mass are estimated to affect more than half of people over the age of 50 (11). Eating foods rich in the above micronutrients may help reduce the risk of bone loss and skeletal failure.

Most people do not consume enough calcium. While people may opt for calcium supplements, research shows that they are not as effective in improving skeletal health. It is best to obtain calcium and other micronutrients from dietary sources (14). Adding cheese or yogurt to your black bean dish can help you increase your calcium intake.

Potent Source Of Antioxidants

Antioxidants are compounds that help destroy free radicals which are associated with chronic diseases such as diabetes, heart disease, stroke, and cancer. Black beans contain phytonutrients such as anthocyanidins, saponins, kaempferol, and quercetin which possess antioxidant properties.

The coating is particularly rich in phytonutrients. One study in mice found that black bean seed coat extract which contains flavonoids and saponins may reduce hepatic lipogenesis and stimulate cholesterol excretion (7)

Lowers Risk Of Heart Disease

Heart disease is the number one killer worldwide. The fiber, folate, potassium, vitamin B6 and phytonutrients in black beans are all essential for optimal heart health. Consumption of fiber has been shown to reduce total serum cholesterol and low-density lipoprotein concentrations (6).

Potassium on the other hand helps maintain healthy blood pressure and prevent the formation of plaques. Generally, higher dietary potassium is linked to reducing the risk of stroke, coronary heart disease, and cardiovascular disease (13).

Quercetin is a flavonoid that exhibits possible cardioprotective effects. The antioxidant may inhibit LDL oxidation, reduce adhesion molecules, and decrease inflammatory markers (19). Finally, saponins are antiatherosclerotic, vasodilators, which might help reduce blood cholesterol. All these mechanisms may help reduce the risk of cardiovascular diseases (18).

Reduces Risk Of Cancer

Emerging evidence shows that populations with a high legume consumption have a lower risk of cancer and degenerative conditions (4). The selenium, fiber, and saponins may be responsible for their anti-cancer effects. 

Some studies show that high levels of selenium in the diet may help reduce the risk of certain cancers such as breast, gastric lung, esophageal, and prostate cancer (16). However, high selenium exposure may have different effects on different types of cancer.

A more plant-based diet in general has also been associated with reduced risk of cancer in general.

Aids In Weight Loss

Eating black beans may help promote weight loss. This is because they are high in fiber and protein. The calories in black beans,100 grams, are about 132. You are thus able to enjoy this nutrient-dense, low-calorie bean variety without having to worry about your calorie intake. 

Fiber helps promote satiety keeping you full longer. This removes the need for unnecessary snacking or overeating that often results in weight gain. Studies suggest that eating about 25 to 30 grams of fiber daily should be sufficient to aid in weight loss (5).

Protein on the other hand helps build muscle when combined with exercise thus increasing your metabolism as muscle burns more calories than fat. Eating a protein-rich diet also promotes satiety. Some experts recommend that you should aim to eat at least 1.2 to 1.6 grams of protein per kilogram of body weight for weight loss (20).

Black Beans Side Effects

Black beans are safe for human consumption. There are, however, a few sensitive people who need to watch their consumption of black beans.

Allergies

Even though black bean allergies are uncommon, anyone with peanut or soy allergies should consider getting tested  (12). If you are allergic to one type of beans (pinto, green, or kidney beans), it may mean you are sensitive to other types.

Digestive Issues

Eating black beans can cause digestive issues such as gas and stomach discomfort. This is because they contain oligosaccharides known as galactans. Galactans are complex sugars that are indigestible by the body because they lack an enzyme known as alpha-galactosidase (15).

If you experience these symptoms, eat these beans in small amounts. Soaking dried black beans in water for longer and draining the water used to soak the beans may also help. If available, buy sprouted beans instead of dried beans.

Some Varieties May Be High In Sodium

Canned black beans contain a relatively high sodium content compared to home-cooked ones. Luckily there is a simple solution – just drain and rinse the beans in water. Research shows that draining lowers the Sodium content by about 36% while draining and rinsing lowers it by about 41% (2).

Also, check the sodium content of black beans when shopping. Go for brands of black beans that have a low sodium content. Consumption of too much sodium may increase your blood pressure if you have hypertension (17).
