Beans, in some cases, can bring some harm to some people.

Among them are:

  • Flatulence (gases);
  • Stomachache;
  • Abdominal pain;
  • Indigestion.

These symptoms occur, in general, due to problems in the digestion process. When not being digested completely, the remains of beans serve as food for bacteria in the intestine, which, when fermenting these leftovers, produce excess gases , which cause flatulence.

How to make beans to avoid gas (flatulence)?

The consumption of beans can cause flatulence in some people.

For those who suffer from the problem, but do not want to stop consuming the grain, there is a tip to reduce the symptom.

Soak them in water overnight before cooking. After the period, just dispense the water and cook normally, in clean water.

This helps to reduce indigestion, since substances such as oligosaccharides – sugars -, which are more difficult to digest and help to cause gases, pass into the water, decreasing its quantity in beans.

Which bean contains the most iron?

Despite the fact that all types of beans contain a large amount of iron in their composition, the black beans are ahead in this regard. With about 1.5mg of iron per 100g, black beans are the best choice for those who want to increase the mineral in the body.

Iron is responsible for the formation of hemoglobin, a protein found in red blood cells and responsible for the transport of oxygen throughout the body. Thus, it is extremely important for the circulation of the organism.

In addition, it assists in the proper functioning of the immune system, which protects the body from illness.

It is also a reliever of PMS symptoms (Pre Menstrual Tension) and participates in the production of substances such as collagen, which help to make the skin look healthy.

White beans lose weight?

It depends . White beans are beneficial for health and can help weight loss. But in general, white bean flour is the most used for this purpose.

This is because it is rich in a substance called Faseolamine – protein – which makes it difficult for the body to absorb carbohydrates.

This is because the protein inhibits the action of the enzyme responsible for transforming the starch – carbohydrate – into sugar (amylase). In this way, the compound is not digested, but sent directly to the intestine and eliminated through feces.

Thus, the absorption of starch, which would later be transformed into sugar, is reduced, helping to reduce weight.

However, it is worth remembering that the isolated consumption of food or flour will not cause significant changes in the balance. It is necessary to combine the intake of beans with a balanced diet and physical exercise.

What happens if I don’t eat beans? How to replace?

The main problem related to not consuming beans is the lack of iron in the body. But, if it is replaced by other options that have the same nutritional value, its absence will not cause major problems.

Some alternatives for the grain are:

  • Chickpea;
  • Soy;
  • Lentil;
  • Peas.

These grains, which are part of the legume family, have nutrients similar to beans, and can supply part of the organism’s needs.

Whether in beans or any other food in the legume group, a tip to enhance the absorption of iron by the body is to consume them together with sources of vitamin C, such as orange juice, for example, because the vitamin is an absorption optimizer of the mineral.

Beans are an almost indispensable food in the daily lives of some people.

Consuming the grain, in addition to its flavor, can provide health benefits such as fighting anemia and even helping to lose a few pounds on the scale.
