Little-known blood pressure lowering effects of black beans

Beans are not only delicious and nutritious, but can also be prepared in many different dishes. One of the most nutritious beans is black beans. Black beans not only help control blood pressure but also help improve sleep.

A cup of cooked black beans contains about 15 grams of fiber, 610 mg of potassium, 240 mg of phosphorus, 120 mg of magnesium, more than 46 mg of calcium, and many other important nutrients. Black beans also contain phytochemicals and amino acids that help improve blood vessel function and sleep, according to the medical information site Medicine Net (USA).

All of these effects can help improve blood pressure in people with high blood pressure. High blood pressure is a condition in which the blood circulation creates pressure on the artery walls. When this pressure exceeds the normal level, it leads to high blood pressure.

Normal blood pressure will fluctuate at 120/80 mmHg. However, in people with high blood pressure, this index can reach 130/80 mmHg or higher.

In a study on mice published in the journal Nutrients , scientists looked at the effects of black beans and white beans on blood vessel function in mice with high blood pressure.

The results showed that black beans help blood vessels become more elastic, thereby reducing blood pressure. However, this was not found in white beans. The study also found that the blood pressure-lowering benefits of black beans were only maintained when eaten regularly. This means that to take advantage of the benefits of black beans, people should include this plant in their daily diet.

Not only does black beans help improve blood pressure, they also help you sleep better thanks to their richness in tryptophan. This is an amino acid that is essential for the synthesis of two hormones that help promote sleep: melatonin and serotonin.

Many research evidences also show that not only black beans but also other types of beans rich in tryptophan have the effect of helping to improve sleep quality and sleep time, while reducing the condition of light sleep and the number of times waking up during the night. In addition, tryptophan is also essential for muscle activity, neurotransmitter balance and many other functions, according to Medicine Net.
