Description

Health food for stabilizing and regulating blood pressure and improving sleep and preparation method thereof
Technical Field
The invention relates to a health food for improving physical quality and life quality, in particular to a health food capable of stabilizing and regulating blood pressure and improving sleep and a preparation method thereof.
Background
Hypertension is a common disease in humans. They can be divided into two categories according to their pathogenesis. One type refers to the condition that no pathogenic cause can be found clinically, and is called essential hypertension: another group of diseases refers to the diseases with definite etiology, such as chronic nephritis and pheochromocytoma, which are called secondary hypertension. More than 90% of hypertensive patients are essential hypertension.
Hypertension is a common disease of middle-aged and old people in modern society, and the number of hypertension patients in China is estimated to exceed 1 hundred million. The patients with hypertension have numbness of limbs, headache, dizziness and insomnia in mild patients, and myocardial infarction, cerebral atrophy, apoplexy and angiosclerosis in severe patients, which endanger life. Many drugs for treating hypertension have side effects to a certain extent, and patients can have the adverse phenomena of myasthenia of limbs, dizziness, spittle, sudden memory drop, decreased or even disappeared libido, inappetence, senile dementia and the like after taking the drugs continuously, so that the patients with hypertension feel worried about taking the drugs.
It is known that the regulation of blood pressure is mainly achieved by increasing or decreasing catecholamines and 5-hydroxytryptamine in the central and peripheral nervous systems. Therefore, the blood pressure fluctuation is caused by emotional stress and insufficient sleep.
Additional studies have shown that: angiotensin II is one of the strongest vasoconstrictors known to produce a strong boosting effect by contracting arterioles, exciting sympathetic nerves, and stimulating the adrenal cortex to secrete aldosterone. Angiotensin II is converted from angiotensin I by the action of Angiotensin Converting Enzyme (ACE). Therefore, inhibition of Angiotensin Converting Enzyme (ACE) activity can prevent the production of angiotensin II, thereby preventing blood pressure from rising.
In addition, blood ammonia elevation also causes blood pressure to rise.
The research finds that some natural substances have the function of regulating blood pressure. For example, gamma-aminobutyric acid (GABA), a nonprotein amino acid, which is present in high amounts in the brain of higher animals, is an inhibitory transmitter of the central nervous system and plays a role in controlling the cardiovascular system and regulating blood pressure through the receptor system of gamma-aminobutyric acid in the brain; recently, animal in vivo experiments also confirmed that gamma-aminobutyric acid (GABA) has a significant inhibitory effect on the activity of Angiotensin Converting Enzyme (ACE). Therefore, the function of regulating blood pressure can be achieved;
theanine can reduce the concentration of 5-hydroxytryptamine and 5-hydroxytryptamine in rat brain by activating dopaminergic neuron, and has effect of inhibiting blood pressure increase. Can reduce the content of 5-hydroxytryptamine after administration of theanine to rats, so that the synthesis of 5-hydroxytryptamine in brain is reduced and the decomposition of 5-hydroxytryptamine in brain is increased; furthermore, theanine can stabilize emotion by changing brain waves, thereby preventing blood pressure from rising;
catechin compounds have certain effect of inhibiting Angiotensin Converting Enzyme (ACE) activity.
Therefore, the search and development of pure natural substances for regulating blood pressure with less side effects has become a development trend in the research and development work in the field.
