2. Anti-aging: Free radicals are harmful compounds produced in the process of human oxidation reaction, which have strong oxidation. It can cause lipid peroxidation in the body to damage human health and accelerate the aging of the body. Melanin, anthocyanin and other substances contained in black food can capture free radicals, reduce the production of peroxides, act as superoxide dismutase (SOD), and also have the antioxidant capacity of glutathione (GSH), which can eliminate free radicals in the body in many ways.
3. Improve anemia: The iron (Fe) content in black food is very high, which can obviously improve nutritional anemia. For example, people have long found that eating black rice is particularly effective for dizziness, anemia, white hair, soreness of waist and knees, night blindness and tinnitus, and long-term consumption can prolong life. Therefore, people commonly call it "medicated rice" and "longevity rice". Because it is most suitable for pregnant women and parturients to replenish blood, it is also called "moon meal" and "blood meal".
4. Anti-cancer and anti-cancer: Black food has anti-tumor effect, on the one hand, because it can scavenge free radicals, reduce the probability of free radicals causing damage to human body and causing tumors, on the other hand, because it can inhibit the formation of nitrosamines, a strong carcinogen.
5, brain: melanin in black food has the effect of stabilizing the autonomic nerves of the brain, which can prevent memory loss. The anthocyanin contained in it has super antioxidant capacity, which can prevent harmful and toxic substances from entering the brain, thus protecting the normal physiological activities of the brain.
6. Lowering blood lipid: Studies show that hyperlipidemia can cause atherosclerosis and is a risk factor for stroke, coronary heart disease, myocardial infarction and sudden death. Nutrients in black food help to reduce the cholesterol content in the body, thus preventing the occurrence and progress of atherosclerosis and helping to prevent and treat cardiovascular and cerebrovascular diseases.
7, Yiqi Bushen: kidney is one of the five internal organs of the human body. Traditional Chinese medicine believes that kidney and bladder are exterior and interior, which mainly store essence, innate essence and acquired essence, and mainly develop, grow and reproduce. "Su Wen. "Ancient Naivety Theory" wrote: "The kidney governs water and hides in the essence of the five internal organs", so it is also called "the innate foundation". Traditional Chinese medicine believes that the health care function of black food mainly has the function of "tonifying kidney".
8. Improve sleep: Sleep is a necessary process of life, good sleep is a sign of physical and mental health, and poor sleep is mostly a sign of distress and disease. Studies have shown that a variety of black foods have good sedative and sleep-improving effects.
9, increase immunity: immunity is the body's own defense mechanism, is the body's ability to identify and destroy any foreign body (virus, bacteria, etc.). ); The ability to deal with the aging, injury, death and degeneration of their own cells, as well as the ability to identify and deal with mutant cells and virus-infected cells in the body. Black food can significantly increase human immunity.
10, black hair beauty: the lack of melanin in hair will cause hair to turn yellow and white, and the nutrients contained in black food can make hair black and shiny.
1 1. Anti-stress response: Stress response means that when the body is suddenly subjected to strong harmful stimulation, the concentration of adrenocorticotropic hormone in the blood rises rapidly through the hypothalamus, and glucocorticoid is secreted in large quantities, thus increasing the body's tolerance to "tide over the difficulties". From this point of view, stress reaction is beneficial to human body, but excessive or frequent stress reaction will make the body in a "tired" state and is harmful to human body. Black food can resist stress by scavenging free radicals, enhancing immunity and calming down.
