Beans lower blood cholesterol levels

The high level of fiber in the product, both soluble and insoluble (there is a daily requirement in one 200-gram serving), makes beans dishes a must for inclusion in the diet for people suffering from constipation and other disorders of the digestive tract. So in the digestive tract, soluble fibers form gel-like substances that contribute to the removal of bound bile from the body, and with it cholesterol.

Beans for diabetes

The same fiber does not allow the blood sugar level to rise rapidly after a meal, which is extremely important for diabetics.

Doctors conducted a study, it involved 2 groups of patients who suffered from type 2 diabetes. One group had a standard diabetic diet with a daily fiber intake (24 g per day). For people from group 2, foods with a high fiber content (50 g of fiber per day) were introduced into the diet. This experiment showed that people from the second group over time had lower blood sugar and insulin levels than representatives of the first group. At the same time, their cholesterol decreased by 7% and the level of triglycerides by 10.2%.

Reducing the risk of heart disease and improving vascular function

For 20 years, doctors in many countries have studied the relationship between diet and the number of deaths caused by coronary heart disease. The experiment involved representatives from countries such as Greece, Italy, USA, Netherlands, Japan and the former Yugoslavia. The total number of participants in the experiment was 16 tons. people (middle-aged men). The features of food rations in different countries were taken into account. After analyzing all the data obtained, the scientists published conclusions indicating that the consumption of legumes reduces the risk of death from heart disease by 82%.

The benefits of beans in this case are provided due to the content in the product of a significant amount of magnesium and folic acid and iron. The mechanisms of action are as follows:

  • folic acid reduces the level of homocystene, which, at high concentrations, causes a stroke or abnormalities in the work of peripheral vessels. One serving contains 57.3% of the RDI of folate
  • magnesium promotes better blood circulation, which means it improves the flow of oxygen and nutrients throughout the body, which reduces the risk of a heart attack. One serving contains about 20% of the RDA for magnesium
  • iron (part of hemoglobin). This element is involved in the transport of oxygen throughout the body, and is also involved in metabolic processes. One serving of beans contains 28.9% of the body's RDA for iron. I would like to note that the need for iron increases sharply in women during the menstrual cycle, pregnancy, and also during lactation.

If a person does not eat meat, then the introduction of beans into the diet can significantly balance the diet. One serving contains 30.7% (15.3 g) of the RDA.
