What are the effects of barley tea and tartary buckwheat tea, and which is better?

Buckwheat, also known as tartary buckwheat, is extremely rich in nutrition and a medicinal crop with good medicinal value. Protein in tartary buckwheat is mainly glutenin, water-soluble albumin and salt-soluble globulin. Its total amino acid content is 107%, and 18 amino acids are complete. Threonine 0.4 178, valine 0.5093, methionine 0. 1834, leucine 0.7570, lysine 0.6884, tryptophan 0. 1376, isoleucine 0.4542 and phenylalanine 0.54 13. Tartary buckwheat contains 9 kinds of fatty acids, among which oleic acid and linoleic acid are very high, accounting for 80% of the total fat content. Linoleic acid is the most important essential fatty acid for human body and cannot be synthesized in vivo. It is called VF, which can promote the growth and development of children, lower blood pressure and cholesterol for adults, and prevent and treat coronary heart disease and hypertension. According to the comparison of the above data, the amino acid content of tartary buckwheat is extremely high, and the content of lysine and tryptophan is higher than that of buckwheat. Bitter buckwheat contains picroside, which has the function of clearing away heat and toxic materials. Tartary buckwheat contains high medicinal components-bioflavonoids, which can be used to treat diabetes, retinopathy, cerebral hemorrhage, gastric bleeding, ulcers and other diseases caused by diabetes. Tartary buckwheat contains more rutin. Generally, buckwheat is 0.02-0.798%, and tartary buckwheat is 1.08-6.6%. The rutin content of tartary buckwheat varies with varieties and regions. The rutin content of tartary buckwheat in Lingqiu County of Shanxi Province reached 4PPM. Rutin is used to treat hemorrhagic diseases caused by capillary fragility and as an adjuvant therapy for hypertension. There are many records about the prevention and treatment of tartary buckwheat in ancient books in China. It is said in Qi Yao Min's Book that "those who are afraid of the cold at the head wind will eat noodles, soup and cakes, and sweat more, even though it takes more than ten years." There is a record of "invigorating stomach and benefiting qi" in illustrated materia medica. "Compendium of Materia Medica" has the exposition of "reducing qi, relaxing intestines and grinding stagnation, eliminating heat, reducing swelling, wind pain, removing turbid blood stagnation and accumulating diarrhea". Modern medicine has proved that tartary buckwheat has the functions of treating diabetes, hypertension and retinitis caused by it, and wool therapy, and can also be used as a nourishing and strong medicine. Animal experiments and observations in Beijing Tongren Hospital show that eating tartary buckwheat powder has a significant effect on controlling and treating diabetes. Cerebrovascular sclerosis, cardiovascular diseases and hypertension caused by hypertension also have good therapeutic and preventive effects, and can also play the roles of invigorating stomach, promoting digestion, enhancing immunity, resisting inflammation and preventing cancer. Buckwheat hypoglycemic tea is made of buckwheat, a specialty of Lingqiu, as the main raw material and other natural plants. In the production process, because the original qualities such as chlorophyll, rutin and vitamins are well maintained, it has become an ideal health care product for patients. This product has been clinically tested in 108 diabetic patients by Institute of Endocrinology, Shanxi Medical College.

Annex II:

Tartary buckwheat has the function of "regulating blood sugar and blood lipid, improving cardiovascular and cerebrovascular microcirculation" and is "the food source of 2 1 century". According to Compendium of Materia Medica, tartary buckwheat tastes bitter, flat and cold, which is beneficial to physical strength, refreshing, eyes and ears, and has the functions of lowering qi, relaxing intestines and strengthening stomach. Polygonum multiflorum and rhubarb, which are familiar to everyone, belong to Polygonaceae and are not common gramineous crops. Tartary buckwheat can not only satisfy hunger, but also has a unique diet health care function. Its vitamin B2 is 4-24 times higher than that of wheat, rice and corn, and it also contains rutin and chlorophyll that other grains lack, and its mineral elements are also higher than other grains to varying degrees. Protein content of tartary buckwheat is 6 1.5, vitamin B2 is 3. 16, and flavonoid rutin is 13.6 times of buckwheat. Rutin is a key substance for lowering blood sugar, lowering blood lipid and improving cardiovascular and cerebrovascular microcirculation.

"zhongnong dachaolai" tartary buckwheat tea is made of 100 pure natural tartary buckwheat, which is rich in bioflavonoids of tartary buckwheat and has the effect of bioflavonoids;

Physiological activities of bioflavonoids from tartary buckwheat;

First, the role of endocrine system

1, hypoglycemic effect

Buckwheat bioflavonoids can promote the recovery of islet β cells, reduce blood sugar and serum cholesterol, improve glucose tolerance, and resist the hypoglycemic effect of adrenaline. At the same time, it can also inhibit aldose reductase, so it can treat diabetes and its complications.

2. Hypolipidemic effect

Quercetin, which is rich in bioflavonoids from tartary buckwheat, can reduce triglyceride, total cholesterol and atherosclerosis index.

B, the role of the cardiovascular system

1, the effect on myocardium

Can be used for treating arrhythmia, angina pectoris, myocardial infarction, etc.

2. Influence on blood vessels

Rutin, a bioflavonoid rich in tartary buckwheat, can dilate blood vessels, while quercetin and morin can improve the contraction and relaxation of vascular smooth muscle.

C, antibacterial and antiviral effects

According to research, quercetin, morin and camphor rich in tartary buckwheat have antibacterial and antiviral effects. Clinical application of this flavone has the peculiar effects of removing putrefaction, promoting granulation, diminishing inflammation and relieving pain on ulcers caused by various reasons.

D, antioxidation

3-OH, 5-OH, 4- carbonyl and 2,3- position double bonds play a leading role in inhibiting the automatic oxidation of oils and fats. The ability of inhibiting oil oxidation quercetin > morin > rutin.

E, cancer prevention, anti-cancer effect

Flavonoids such as quercetin, a bioflavonoid rich in tartary buckwheat, have achieved anti-cancer effects mainly through three ways, namely, anti-free radical effect, direct inhibition of cancer cell growth and anti-carcinogenic factors. Pentagonal flavonoids contained in bioflavonoids of tartary buckwheat are the first choice for cancer prevention, anticancer and treatment.

F. Scavenging free radicals

Free radicals are the evil sources leading to cancer, aging and cardiovascular and cerebrovascular degenerative diseases. Because tartary buckwheat flavone is easy to oxidize, it has the function of scavenging free radicals. The molecular structure of bioflavonoids from tartary buckwheat accords with the theory of effective phenolic hydroxyl groups and has strong free radical scavenging ability. They have five hydroxyl groups and can be used as sufficient hydrogen donors to reduce free radicals, so as to achieve the purpose of eliminating free radicals and preventing aging, cancer and cardiovascular and cerebrovascular diseases.

G, the influence on bone tissue

Buckwheat bioflavonoids can be used to treat bone diseases and osteoporosis, and its mechanism lies in the following aspects: firstly, it can not only inhibit the increase of collagen synthesis of prostaglandin E2(PGE2), but also inhibit the decrease of collagen synthesis of PGE2, that is, it can inhibit {BH }- proline from entering digestible collagen and non-collagen protein, which mainly acts on non-collagen synthesis at low concentration of PGE2, and mainly acts on collagen synthesis at high concentration of PGE2. Therefore, it can be used to treat bone diseases; Second, it can improve the sensitivity of thyroid gland to estrogen, strengthen the secretion of calcitonin by thyroid C cells, and finally inhibit bone absorption to treat osteoporosis; Third, it can inhibit the decrease of bone mineral density and bone calcium content caused by dietary calcium deficiency and vitamin D.

Effect on immune system

Buckwheat bioflavonoids can obviously and effectively increase the nonspecific immune function and humoral immune function of the body.

First, protect the liver

Buckwheat bioflavonoids have a certain effect on acute and chronic hepatitis, liver cirrhosis, fatty liver and toxic liver injury caused by galactosamine and carbon tetrachloride. The results showed that tartary buckwheat flavonoids had obvious inhibitory effect on the increase of MDA content in liver caused by carbon tetrachloride. Can reduce the consumption of glutathione (GSH) caused by liver injury; It can protect the integrity of cell structure and prevent the activity of soluble enzymes such as transaminase in liver cells from increasing due to leakage from cells; The liver-protecting mechanism of tartary buckwheat bioflavonoids ultimately lies in its antioxidant and anti-free radical effects.

J, anti-ultraviolet effect

Flavonoids such as quercetin, a bioflavonoid rich in tartary buckwheat, are a sunscreen and have the function of absorbing ultraviolet rays. It can protect bioactive substances such as ascorbic acid from oxidation and keep its activity. It is an excellent antioxidant, and its chelation and gene expression can obviously reduce the oxidative denaturation of fat. Flavonoids, in particular, have significant health care effects on skin, youth and blood vessels, as well as anti-inflammatory effects, so some people call them "skin nutrients".

In recent years, tartary buckwheat protein complex (TBPC) was prepared from tartary buckwheat, and its nutritional components and anti-aging effects were studied. The results showed that the content of protein in tartary buckwheat complex protein was 63.4, fat 12.7, carbohydrate 10.2, ash 3.5, crude fiber 0.4 and water 9.8. At the same time, it also contains a variety of amino acids, and its essential amino acids and non-essential amino acids account for about 45.8% of all amino acids, and contain certain fatty acids and trace elements.

Animal experiments showed that after feeding the tartary buckwheat protein complex, the activity of SOD (superoxide dismutase, which has anti-free radical effect) in red blood cells of mice increased 15. 1, the activity of CAT (catalase, which catalyzes the decomposition of hydrogen peroxide into oxygen and water) increased 13.4, and the activity of GSH-PX (glutathione peroxidase) in whole blood increased. The activity of preventing free radical generation increased by 23.2, and the activities of SOD, CAT and GSH-PX in liver increased by 19.2, 15. 1 and 18.4 respectively. However, the content of malondialdehyde (lipid peroxide) in blood and organs of mice decreased, especially in the heart, which indicated that tartary buckwheat protein complex had a certain scavenging effect on lipid peroxide in vivo.

According to literature reports, free radicals in the body can damage islet β cells, resulting in decreased islet function and increased blood sugar. Tartary buckwheat protein complex has the function of delaying aging and lowering blood sugar because it improves the activity of antioxidant enzymes in the body, has a certain scavenging effect on lipid peroxide, and improves the body's ability to resist free radicals.

With the improvement of people's living standard, the acceleration of work pace and the change of diet structure, the number of people suffering from diabetes and hyperlipidemia in China is increasing day by day. Long-term use of therapeutic drugs will produce various side effects. Clinical observation shows that taking tartary buckwheat tea has a certain therapeutic effect on diabetes and hyperlipidemia, and has no toxic and side effects.

The results showed that replacing some carbohydrates in the diet of diabetic patients with tartary buckwheat tea significantly improved all biochemical indexes and reduced the dosage of hypoglycemic drugs. This fully shows that tartary buckwheat tea has a positive effect on diabetes, and can be taken as a diet therapy for patients with diabetes and hyperlipidemia for a long time.

To sum up, tartary buckwheat tea relies on its two main components: tartary buckwheat bioflavonoids &; Tartary buckwheat protein complex plays a great role in promoting and improving human health. With the high development of modern medicine and the continuous progress of processing technology, tartary buckwheat, a plant growing on the plateau, will be praised by more people, and tartary buckwheat tea will also make great contributions to the health of all mankind!
