Discover the 7 benefits of black beans and side effects.

The benefits of black beans for a better mood and improved health involve the prevention of cardiovascular diseases and the reduction of the risk of certain types of cancer.

What are black beans?

Black beans are a simple and delicious dietary addition that can improve your overall health in many ways!

7 benefits of black beans


Black turtle beans, more commonly known as black beans, are shiny, black members of the common bean family,  Phaseolus vulgaris.

They are most commonly found and have become popular in Latin American cuisine, and are known by many names in various South and Central American cultures.

Although they have been grown and cooked for thousands of years in South America , black beans did not cross the Atlantic until the 1500s on the ships of European explorers.

The general shape of black beans can be changed without losing nutritional benefits, although some may be lost when they are prepared in soups or when they are ground and exposed to high temperatures.


Widespread growth and low cost are what initially made black beans a cultural staple, but as more is learned about the benefits of adding black beans to healthy diets, it is followed for several other reasons.

A popular preparation technique is to soak black beans in water before cooking or eating.

By allowing the beans to soak in water, studies have shown that certain phytates and tannins are removed, reducing nutrient availability, and the beans also retain beneficial “resistant starch” while losing some of the total carbohydrate content.

In some parts of the world, beans are given a separate box in the Food Pyramid, because they are such a beneficial and vital part of those cultural diets.

They are very popular with vegetarians because when combined with brown rice, a “complete protein” is formed.

A common problem in vegetarian diets is acquiring adequate amounts of protein, so black beans and brown rice can offer a simple and inexpensive solution.

Nutritional value of black beans

Black beans are also high in flavonoids, which have antioxidant capabilities, particularly anthocyanins, and they contain some omega-3 fatty acids, which are considered a “good” form of cholesterol.

Similarly, black beans are a great source of folic acid and have abnormally high levels of the rare compound molybdenum, which is very difficult to add naturally to a health regimen.


7 benefits of black beans

Adding black beans to your diet will provide you with many nutrients and help prevent various health conditions. Let us see the benefits in detail below:

1.- Improves heart health

One of the benefits of black beans that you can add to your diet is the high level of fiber they contain. They have high concentrations of soluble fiber, which has been shown to help lower blood cholesterol.

Soluble fiber attracts water and turns into a gel during digestion, while insoluble fiber adds mass to foods and helps them break down. pass through the digestive system more quickly.

Lowering blood cholesterol can reduce the thickening of artery walls, which in turn can prevent heart attacks and strokes.

Black beans also have small amounts of omega-3 fatty acids, which are “good” forms of cholesterol that balance the negative effects of omega-6 fatty acids and “bad” cholesterols.

They have antihypertensive effects, which means they can improve blood flow, lower blood pressure, and put less strain or oxidative stress on the overall cardiovascular system.

2.- Prevent cancer

Black beans have been shown to reduce the risk of certain types of cancer due to the flavonoids found in their coating.

8 different flavonoids have been found in the seed coat, and three of them are anthocyanins, flavonoids are phytonutrient pigments that produce color and function as antioxidants in the body to fight disease and free radicals.


Anthocyanins are pigments, but they can have a powerful effect on the body, including inhibiting the growth of blood vessels into cancerous tumors, slowing the growth of dangerous cells, and increasing the rate of apoptosis (cell death) in cancer cells.

The anthocyanins, along with all the other phytonutrients found in the seed coat, make black beans a very powerful weapon in the fight against cancer if you add them to your diet regularly!


3.- Relieves digestive problems

Black beans are great for regulating digestive problems because they contain high levels of protein and fiber, making them a “superfood. ”

Protein and fiber help food move through the digestive tract, allowing its nutrients to be removed and then waste to be expelled healthily.

They’re also digested more slowly than meat, which has a similar protein content, so eating beans can leave you feeling full for longer.

Black beans are also smaller than other beans, which people find easier to digest. Over time, with the regular addition of black beans to the diet, the soluble fiber content will absorb water in the stool, which can reduce constipation.

4.- Control blood sugar

Uneven digestive rates can cause unbalanced blood sugar levels in the body, but black beans regulate this problem as well.

As mentioned above, the fiber and protein in black beans keep digestion at a steady rate, so concentrated doses of nutrient absorption do not occur.


Rather, a constant elimination of nutrients occurs throughout the digestive process. When digestion is unstable, spikes or crashes in blood sugar can occur, which are dangerous and even fatal for patients with diabetes or similar conditions.

5.- Treats Sexual Dysfunction

Studies have shown that black beans are extremely high in molybdenum, a rare mineral not often found in foods.

Molybdenum is important for several reasons, mainly because it can break down and detoxify sulfites, sulfites are acidic compounds found in wines, dried fruits, and some vegetables, and many people are very sensitive to its effects, which include headaches and disorientation.

The molybdenum found in black beans counteracts these effects, neutralizing the negative effects so people can enjoy those foods again. Molybdenum also helps in the production of cellular energy and the development of the nervous system.

Additionally, molybdenum has been shown to reduce impotence and erectile dysfunction in older men when consumed regularly. This rare vitamin has been regularly linked to increased energy and interest in sexual activity in older men.

6.- Boost the nervous system

Black beans may also benefit nervous system functions by helping to provide necessary amino acids and molybdenum.

This is because black beans have many vitamins and minerals, plus folic acid plays a key role in regulating specific amino acids required by the nervous system.

Without folic acid in the diet, studies have shown increased levels of homocysteine, which can be a dangerous precursor to neurodegenerative diseases like Alzheimer’s and Parkinson’s disease.


Regularly adding black beans to your diet can ensure safe levels of folate in your system, helping to prevent some of these conditions.

7.- Improve prenatal health

Another benefit of folic acid, found in such high levels within black beans, is its role in protecting babies in the womb.

Folic acid levels in a woman’s body are integral to the normal and healthy development of the fetus, especially in the brain and spinal cord.

By adding healthy amounts of black beans, and therefore folate, to her diet, she can protect her baby while it’s still in the womb.

Side Effects Black Beans

Phytic acid: Beans have natural seed coats that protect their nutritional content from predators and insects while growing in the wild.

One of the components of that seed coat is phytic acid, which protects the seed from premature germination.

If phytic acid is not removed from the bean before eating, it can bind to common minerals like calcium, magnesium, and copper, preventing them from being absorbed as nutrients in the body.

These unabsorbed minerals can build up and cause a variety of conditions, from minor irritations like digestive irritability to more serious issues like hormonal disruption and impaired brain function.


You cook the beans and make sure they are soaked in water to neutralize the harmful effects of phytic acid!

Oligosaccharides – Black beans contain a complex sugar called oligosaccharides, and the human body does not produce any enzymes that naturally break down that sugar.

Therefore, oligosaccharides ferment in the digestive system and begin to produce methane, which is released from the body in unpleasant ways.

Again, soaking the beans in water and making sure they are cooked can greatly reduce several oligosaccharides in the beans, along with reducing all the other organic parts of the beans that are difficult to digest or process.
