Black tea health improves blood circulation
Oxygen supply and metabolism in the body are mainly accomplished through the red cell system. Erythrocytes, also called red blood cells or red blood cells, are the most blood cells in the blood. The hemoglobin contained in the red blood cells can bind to the oxygen in the air, so the red blood cells can transport the oxygen inhaled into the alveoli to the tissues through the hemoglobin, and the carbon dioxide produced in the metabolism of the tissues is also transported to the lungs through the red blood cells and excreted from the body.
Black tea is rich in tea polysaccharides, can enhance the body's immune function, as well as anti-oxidation, scavenging free radicals, anti-radiation damage, protection of hematopoietic function, anticoagulant and thrombosis, reduce platelet aggregation and so on. Tea polysaccharides also increase fibrinolytic enzyme activity, decrease neutral fat, lower total cholesterol and low-density lipoprotein cholesterol, increase the suspension stability of blood cells, and slow down erythrocyte sedimentation. This will improve blood circulation, protect the cardiovascular system, and increase the ability of red blood cells to carry oxygen.
Black tea is rich in protein (about 20% to 30%) and iron, manganese, selenium and other minerals, and various vitamins such as folic acid. The body's main raw material for the production of red blood cells is protein and ferrous iron, but also have an appropriate amount of vitamin B12, folic acid and other auxiliary substances to promote the development and maturation of red blood cells. In addition, vitamin B6, B2, C, E and trace elements copper, manganese, cobalt, zinc, etc. are also needed. It can be seen that black tea provides important nutrients for the generation and maturation of red blood cells.
Modern people have less activity, more high-fat, high-calorie diets and more metabolic diseases. If you often drink black tea, such as high-grade black tea Chancha, you can solve a large part of the "sub-health" problem.
