Brief information about blood pressure

For information, hypertension results from the disturbance of the balance between nitric oxide, the factors which cause the dilation of the vessels and the tightening of the caliber of the vessels, such as angiotensin. Hypertension (hypertension) is one of the most common diseases in the world. Its effects persist over time. It is characterized by very high blood pressure in the blood vessels. This scourge is the cause of various cardiovascular pathologies. Without effective medical treatment, it risks leading to a stroke in the patient.

The benefits of flavonoids on high blood pressure

Etymologically, the term “flavedo” is the origin of the word “flavonoids”. It designates the layer of orange peel that is exposed to the external environment. These compounds are involved in strengthening the tightness and elasticity of the tubes that transport blood in the body, and therefore, their resistance. They also contribute to the improvement of the dilation and irrigation of the arteries as well as the regulation of blood pressure. Flavonoids are valued for their protective actions against all disorders that affect blood vessels and the heart. They preserve lipoproteins from oxidation. Flavonoids are adaptogenic compounds that strengthen the body in its actions to compensate for stress Note that the latter is often the main source of hypertension. Undoubtedly, foods containing a large amount of flavonoids are effective remedies for hypertension. According to the results of one study, the difference in blood pressure between patients with the highest and lowest flavanol intakes varies between 2 and 4 mm Hg. who have the highest blood pressure.

The benefits of polyphenols in the fight against high blood pressure

Polyphenols belong to the family of the most well-known organic molecules. They are found in many foods of plant origin. Polyphenols contribute to the coloring of plants. These are also the compounds responsible for the aroma. When polyphenols are taken with a meal, they defend the human body against oxidation caused by bad cholesterol. This eliminates the causes of clogging in the arteries. The use of therapeutic treatments based on plant polyphenols has proven its beneficial influence in the prevention of hypertension. These compounds increase the production of glutathione and NO (nitrogen monoxide). They also improve vascular tone. In practice, this helps to lower blood pressure. The average quantity of polyphenols provided in the drinks and foods consumed daily is around 1 g per individual.
