The little-known blood pressure-lowering effects of black beans.

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

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

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

Normal blood pressure ranges around 120/80 mmHg. However, for people with high blood pressure, this reading can reach 130/80 mmHg or higher.

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

The results showed that black beans help improve blood vessel elasticity, thereby lowering blood pressure. However, this was not found in white beans. The study also found that the blood pressure-lowering benefits of black beans are only sustained with regular consumption. This means that to reap the benefits of black beans, people should include this plant in their daily diet.

Besides helping to improve blood pressure, black beans also promote better sleep thanks to their high tryptophan content. This is an essential amino acid for the synthesis of two hormones that promote sleep: melatonin and serotonin.

Numerous studies also show that not only black beans but other tryptophan-rich beans can help improve sleep quality and duration, while reducing restless sleep and the number of awakenings during the night. In addition, tryptophan is essential for muscle function, neurotransmitter balance, and many other functions, according to Medicine Net.
