Buckwheat is a set of "nutrition, health care, medical" in one of the natural functional food. China's ancient records on buckwheat disease prevention and treatment. "Qimin Essentials" has "cold head wind, to noodle soup and powder for the cake, more fomentation sweating, although decades are also cured. Tujing Ben Cao" has the record of "solid stomach and intestines, benefiting vitality". The Materia Medica Compendium" has "lowering the gas and broadening the intestinal grinding stagnation, consumption of heat, swelling and wind pain, in addition to the white blood stagnation, splenic accumulation of diarrhea" of the discussion. Recorded buckwheat bitter, flat, cold, has the benefit of qi, renew the spirit, ears and eyes, lowering the gas and broadening the stomach. "Plant Names and Facts" said buckwheat "performance elimination, commonly known as purification of intestinal grass. Buckwheat can lower blood pressure, blood sugar, blood lipids, improve microcirculation and other effects, also known as the "three lower" food.
Lowering blood sugar
Survey showed that the staple buckwheat area of the population, its blood sugar levels and the prevalence of diabetes is significantly lower than the population does not eat buckwheat area. Among them, the staple buckwheat residents of high blood sugar levels (i.e., higher than normal blood glucose levels) detection rate of 1.6%; and non-staple buckwheat population, the detection rate of high blood sugar 7.33%, the latter is nearly four times higher than the former. Staple food buckwheat and non-consumption of buckwheat areas of diabetes is also about one-fold difference in the rate of disease, the former 1. 88%, the latter 3. 84%. This conclusion suggests that buckwheat as an effective way to reduce the incidence of diabetes mellitus of mixed crops, should be more in the people's table.
Lipid-lowering
Animal experiments have shown that buckwheat flavonoids can make the triglyceride levels in hyperlipidemic mice and rats with high blood cholesterol and triglyceride levels significantly reduced; but it does not reduce the level of high-density lipoprotein levels of the two, so buckwheat flavonoids have lipid-lowering effect. In addition, the raw buckwheat needs to be properly baked and processed to make tea to drink, but the buckwheat baking process requires a high degree of sophistication, it is very easy to fry over fried paste, or fry the fire is not, destroying the buckwheat's active ingredients, affecting the taste as well as rutin exudate rate. This is because the buckwheat bioflavonoids rich in quercetin, etc. can reduce triglycerides and total cholesterol content, reduce the atherosclerosis index.
The role of the myocardium
Buckwheat is rich in bioflavonoids is the main component of rutin, also known as VP, and its main effect is to soften blood vessels, improve microcirculation, clearing heat and detoxification, blood circulation, blood stasis, pulling out the toxicity of the muscle, the benefit of energy and refreshment, and have a lowering of blood glucose and urinary glucose effect. Dr. Mitchell Hertoghmu of the Netherlands measured the content of bioflavonoids in the diets of 805 elderly men, and found that the daily intake of bioflavonoids is not less than 30 mg of the group, compared with the daily intake of bioflavonoids is not more than 19 mg of the group, the risk of death from coronary heart disease is reduced by 50%. Magnesium has a good regulatory effect on myocardial activity, can make the heart rhythm and cardiac stimulation of conduction to slow down, increase myocardial blood supply, conducive to cardiac diastole and rest. Buckwheat in the magnesium content is more than 11 times that of wheat flour.
The role of blood vessels
Buckwheat bioflavonoids have a variety of physiological functions, including quercetin and mulberry pigment to improve the body's vascular smooth muscle contraction and diastolic function; rutin has a vasodilatory effect, can maintain capillary resistance, reduce its permeability and fragility, promote cell proliferation and prevent the agglutination of blood cells, as well as lowering blood lipids, dilate the coronary artery, enhance the coronary artery. Coronary artery dilation, coronary artery blood flow and other effects. Buckwheat flour rich in vitamins to reduce blood lipids and cholesterol, is the treatment of hypertension and cardiovascular disease is an important adjunct to food (medicine). Buckwheat flour contains some trace elements (such as magnesium, iron, copper, potassium, etc.) for cardiovascular protection.
Antibacterial, antiviral effect
Research has confirmed that buckwheat bioflavonoids rich in quercetin, mulberry pigment, camphene alcohol has antibacterial and antiviral effects. Clinical application of the flavonoids, the various causes of ulcers have a carrion, anti-inflammatory and analgesic peculiar effect.
Scavenging the role of free radicals
Free radicals (free radical) is the cause of cancer, aging, cardiovascular and cerebrovascular degenerative diseases of the source of evil. Because buckwheat flavonoids easily oxidized, so that it has the function of scavenging free radicals. Buckwheat bioflavonoids composed of molecular structure in line with the theory of effective phenolic hydroxyl, has a strong free radical scavenging ability, they have 5 hydroxyl, can be sufficient as a hydrogen donor, so that the free radicals to restore, thus playing a role in scavenging free radicals, to achieve anti-aging, anti-cancer, anti-cerebrovascular disease purposes. Hepatoprotective effect of buckwheat bioflavonoids on acute and chronic hepatitis, cirrhosis, fatty liver, as well as due to galactosamine and CCl4 and other causes of toxic liver injury have a certain degree of efficacy. Studies have shown that buckwheat bioflavonoids on CCl4 caused by liver malondialdehyde (MDA hepatic lipid peroxidation end-products) increase in the content of a significant inhibitory effect; can reduce liver injury to glutathione (GSH) consumption; can protect the integrity of the cellular structure, to prevent the liver cells of the transaminases and other soluble enzymes due to the leakage from the cells and increased activity. Buckwheat bioflavonoids liver protection mechanism ultimately lies in its antioxidant and anti-free radical effect.
