14 Health Benefits Of Beans

The health benefits of beans are numerous: they improve digestion and bone health, prevent heart disease, have anti-cancer properties, help treat diabetes, are rich in nutrients and others that we will explain below.

Common beans ( Phaseolus vulgaris ) are legumes that are grown around the world and are consumed as a high-nutrient food. Like all legumes, they are rich in fiber, protein and also contain vitamins and minerals that strengthen the body.


All beans are high in starch, a type of complex carbohydrate that is released slowly in the body, so they provide a feeling of fullness and prevent spikes in blood sugar.

Despite their starch content, beans are classified as vegetables and offer a large amount of vitamins and antioxidants just like vegetables.

They can even be considered proteins, since they provide a significant amount of plant proteins that are very necessary in the diet, almost without providing any fat and totally free of cholesterol. This is an advantage over animal proteins.

Beans are available throughout the year and can be used in all kinds of preparations, from stews and soups to adding them to burritos and tacos as a side. We invite you to know why you should incorporate this superfood into your diet right now.

Healthy properties of beans

1- They improve digestion

Beans are foods high in fiber, which is why they can be used as an aid to prevent constipation and improve the health of the digestive system. Besides this, beans are beneficial for the flora of the large intestine.

2- They help maintain low blood pressure

Beans are naturally low in sodium, one of the key factors in keeping blood pressure low.

They also contain essential minerals such as magnesium, potassium and calcium, which together have been shown to be beneficial in reducing rates of hypertension.

3- They promote optimal bone health

As we mentioned earlier, beans are rich in essential minerals like iron, calcium, phosphorus, magnesium, zinc, and copper.

Within the human body, bones are composed of 60% magnesium, 99% calcium and 80% phosphorus, therefore the contribution of these components is essential to maintain a healthy and strong bone structure.

In particular, it is calcium and phosphorus that play the most important role in the stability of our bones, while zinc and iron help to preserve the elasticity and strength of the joints.

4- They can prevent heart disease

People who consume more legumes have been shown to have a lower risk of cardiovascular disease.

The fibers in beans, as well as folates, B vitamins, potassium, and other phytonutrients, help keep your heart healthy.

On the other hand, beans have quercetins, a flavonol that is considered a natural anti-inflammatory, allowing to reduce the risk of arteriosclerosis.

Beans also contain saponins, with properties that help reduce blood lipids and levels of LDL cholesterol or “bad cholesterol”, which helps protect the heart and cardiovascular system.

5- They have anti-cancer properties

Beans have chemicals inside them known to be effective in treating cancer. These chemicals, specifically isoflavones and phytosterols, act in the body by preventing the development of hormone-related cancers, such as breast and endometrial cancers in women or prostate cancer in men.

In addition, the isoflavones present in beans help to reduce angiogenesis, that is, the vascularization process of a tumor, thereby reducing its size and facilitating its elimination by the body.

Other components within beans that help prevent cancers are saponins, which prevent cancer cells from multiplying and spreading within the body.

Among the essential minerals they contain is selenium, which is not always present in all vegetables.

Selenium can assist liver enzymes in their detoxification function, thereby promoting the elimination of some cancer-causing compounds in the body. Another advantage of selenium is its anti-inflammatory effect, which can slow the growth of a tumor.

Beans are rich in folate (vitamin B9), an essential vitamin for the body that must be consumed daily.

Folate or folic acid has repair and improvement effects on human DNA, so it can protect it from certain damages such as some types of cancers, especially colon cancer.

6- They reduce cholesterol

Beans are a food very high in soluble fiber, which contributes to the reduction of cholesterol and triglyceride levels in the body.

A study carried out by the University of Toronto, Canada, showed that eating all kinds of legumes once a day – in this case beans – in a three-quarter cup serving, reduces “bad cholesterol” or LDL cholesterol by 5 %.

This also translates into a 5% lower risk of contracting cardiovascular diseases, which correspond to one of the most important causes of death around the world.

Beans, in addition to being an important source of vegetable proteins, do not provide fat, which makes it possible to replace some animal foods and thus avoid “bad” fats, such as trans fats that are usually found in meats.

Another benefit is that beans are complex carbohydrates that distribute slowly in the bloodstream, ensuring a stable sugar curve for several hours.

This achieves a correct functioning of the metabolism and prevents diseases such as diabetes, preventing the development of the so-called metabolic syndrome, where high cholesterol is one of its main manifestations.

7- They are a complete package of proteins

Beans are an excellent source of plant protein. One-half cup of beans provides seven grams of protein, the same amount found in 200 grams of fish, meat, or chicken.

In this way, they are an excellent protein to supply to people who are vegetarians, vegans or who simply do not eat a lot of animal proteins.

Proteins are known as the building blocks of life. They are essential for the formation of muscles in our body, they promote the repair of cells and tissues, they take longer to be processed by the body than carbohydrates, so they maintain a feeling of satiety for longer.

They allow to achieve a healthy weight, since they favor the metabolism of fats into energy, instead of storing it in adipose deposits of the body.

Beans provide all the benefits of protein, but without the saturated fat and cholesterol of animal proteins, therefore they are essential in a healthy diet.

8- They help in the treatment of diabetes

People with type 1 diabetes who eat a healthy diet with high levels of fiber daily have been shown to maintain lower blood glucose levels.

The same occurs with type 2 diabetics, who, in addition to reducing their glucose values, also see a decrease in lipid and insulin levels.

This stabilization in the glucose curve not only allows better health, but also promotes a more balanced state of mind, with less irritability, fatigue, tiredness and greater concentration.

Beans are not only complex carbohydrates that are released slowly in the body and keep the blood sugar curve stable, but they also help to lower the levels of “bad cholesterol” in the body, therefore helping to improve the metabolism of the body, helping to keep diabetes in balance.

9- They are a complete food, high in nutrients and low in calories

Beans are not only composed of a large amount of protein, but also have a low glycemic index, which makes them an excellent alternative to a nutritious food that can be incorporated into low-calorie diets.

Its high fiber content promotes the health of the flora in the large intestine, regulating the amount of bacteria and reducing the absorption of toxic substances.

In this way, they also help reduce cholesterol levels and risks of coronary heart disease, as well as reducing the possibility of developing cancer.

They are also rich in flavonoids, recognized for being important antioxidants, with anti-inflammatory and analgesic effects, anti-cancer properties and improvements in blood circulation, preventing the development of venous thrombi and toning heart function.

In addition, flavonoids protect liver function, helping to improve digestive activities. They also protect the stomach, as they help maintain the good condition of the gastric mucosa, preventing ulcers.

10- They help in the treatment of arthritis and rheumatoid diseases

Beans have anti-inflammatory properties that can be helpful in treating joint conditions like osteoarthritis, rheumatism, and arthritis.

Beans have antidiuretic effects that benefit the body in these cases, reducing pain and inflammation.

11- Symptoms decrease during Premenstrual Syndrome

Being rich in manganese, beans help reduce symptoms during the premenstrual period, such as colic and sudden mood swings caused by hormonal cycles. It is recommended to especially prefer green beans and consume them throughout those days.

12- They strengthen the joints

Beans have high amounts of vitamin K, essential for the strength of bones and joints.

Low levels of this vitamin in the body are related to arthritis in the knees and hands, as well as clotting problems, which could make the person more prone to bruising.

13- They allow the absorption of more iron

Beans are also high in vitamin C, known for its antioxidant effects. Vitamin C also promotes the absorption of iron, which also contains beans.

Iron is vital for the health of the body’s cartilage, as well as the collagen found in the skin and in the walls of arteries and veins.

14- They prevent problems during pregnancy

They are an excellent source of folates (vitamin B9), essential during pregnancy and the formation of the fetus, especially to prevent defects in the neural tube of the baby.

Folates are essential components of cell synthesis and division within human DNA.

Other interesting facts

Beans are a complete food that can be found everywhere and very cheaply. For little money, it is possible to access a large amount of nutrients and vitamins that constitute a balanced meal. They have fiber, protein, folic acid, B vitamins, complex carbohydrates, essential minerals, low glycemic index and are 0% cholesterol.

You can take advantage of the benefits of beans in all their forms: mung beans, green beans, chickpeas, found beans, white beans, pinto beans and many more. In all of them you will find the same properties to improve the quality of your diet with a single meal.

It is recommended to prefer fresh beans and prepare them as a base for stews, stir-fries, accompaniments and even within sauces and dressings such as hummus, pesto and others. By grinding them, you can take advantage of all their properties and enjoy their creaminess and flavor complementing other foods.

In the case of using canned beans, it is advisable to look for those with a low sodium intake. However, it is likely that storage processes have lost some of their benefits.

When cooking, the skin can be removed after soaking for eight to ten hours in water or overnight.

With this, the possibility of abdominal distention and discomfort in the large intestine that some people feel after consuming legumes is reduced, due to the oligosaccharides present in the skin of beans, a type of sugar that tends to produce excess flatulence.

The positive is that despite removing the peel, the nutritional content and its properties remain intact.

The bean is a food that man has consumed since the beginning of time, it began to be cultivated by the Native Americans who occupied the territories that today belong to Guatemala, and especially to Mexico.

Precautions to keep in mind when consuming beans

Eating too much beans can introduce excess oxalate into the body. This compound is very abundant in various legumes, it is produced as a waste of the body that is expelled through the urine. High amounts of oxalate in the body can cause kidney problems.
