  • Soaking: once clean, it is advisable to let them rest in water so that they soften and we achieve adequate cooking. To do this, place them in a pot with water (the ratio of liquid is 3 cups of water to 1 cup of beans) and let them boil for 2 to 3 minutes. Then remove from heat and let stand for an hour. Drain and rinse with cold water. Another option for soaking is to cover them directly with cold water and leave them for 8 hours or overnight.

benefits of beans

Beans have been part of the cuisine of many cultures for centuries. For this reason, many researchers decided to analyze its effects on the body, and found certain benefits:

Improves digestion

Most bean varieties share a rich fiber content, an essential component for good gastrointestinal health and digestion.

This is because fiber helps increase the volume of stool, normalizes bowel movements, prevents problems such as constipation or diarrhea and promotes intestinal cleansing, preventing the appearance of ulcers.

Supports cardiovascular health

Beans are rich in iron and copper, two minerals that play a fundamental role in the functioning of the circulatory system.

Iron helps produce red blood cells, thus improving blood circulation and oxygenation of the body. Without it, we are prone to anemia, weakness, and bone problems. While copper is involved in the synthesis of hemoglobin.

Another key mineral for the heart is magnesium, which works in a similar way to potassium, as a natural vasodilator. This reduces the tension in the blood vessels, and therefore blood pressure, preventing heart attacks or strokes.

against diabetes

Many investigations ensure that, due to their nutritional composition, beans are excellent options to add to the diet of people with diabetes and facilitate blood sugar control.

This is because they are rich in protein and fiber that improve insulin sensitivity, have a low glycemic index (a measure of how quickly a food can raise blood sugar), and also offer antioxidant properties.

Another remarkable property of beans is their antioxidant effects. The researchers explain that this is due to the presence of copper and manganese, two minerals that are involved in the production of enzymes that prevent the propagation and impact of free radicals.

These are unstable molecules that affect healthy cell structures and favor the appearance of many diseases, including cancer. For this last reason, many studies have evaluated the anticancer potential of beans.


Although its consumption is shown to be beneficial for most people, beans were also associated with side effects.

Professionals believe that this is due to an excessive intake of fiber or the presence of hemagglutinin in these legumes, which are associated with gastrointestinal problems, such as flatulence, pain, bloating or constipation.

However, these effects have been recorded when bean consumption exceeded three cups per day. Remember, the key is in moderation.


Beans have been part of the human diet for centuries. We can find them of many types, such as white, black, kidney or azuki, although there are 150 varieties.
