Jujube has the effect of strengthening blood tonic. So what is the medicinal value of jujube?
Effect and function of black jujube
In many aspects, we can see the effect of black jujube. Black jujube has a high therapeutic effect. We can use black jujube to cook. We hope to introduce the edible method of black jujube.
Jujube, the scientific name of Jun QIANZI, is one of the five kinds of traditional kidney tonic food. Jujube has rich nutritional value, such as carbohydrate, dietary fiber and fat
Fat, pectin and protein are also rich in vitamins and minerals, such as vitamin A to protect the eyes, vitamin B group to help the body metabolize, and minerals to promote growth - calcium, iron, magnesium, potassium and so on & hellip; & hellip; these nutrients are rich in jujube. What's more, jujube contains tannin, yellow pigment and other bioactive substances. Moreover, it has a strong effect on enhancing the immunity in vivo, and has obvious curative effect on cardia cancer, lung cancer and hematemesis. Jujube contains protein, sugar, organic acid, phosphorus and other nutrients. Jujube is warm and sweet. It has the effect of nourishing kidney and stomach. It is called "nutrition storehouse";
In addition, the biggest nutritional value of jujube is that it is rich in dietary fiber and pectin, which can help digestion and soft stool.
1. Vitamin C
As one of persimmon food, black jujube has the common characteristics of persimmon food rich in vitamin C. Vitamin C is very important for the maintenance of human health. From the synthesis of collagen to the maintenance of microvascular function, from the prevention of gingival atrophy to the alleviation of arteriosclerosis, from the elimination of free radicals and antioxidation to the enhancement of immunity and anticancer disease, vitamin C is needed everywhere. It is no exaggeration to say that without vitamin C, there would be no life!
2. Potassium
The mineral content of jujube is also very rich, especially the potassium content is very high, while the sodium content is much lower, which is very important for controlling blood pressure and maintaining heart health. Because long-term high salt diet will lead to high blood pressure. Although experts recommend that each person should take no more than 6G of salt every day, but most people can't do it in real life. Therefore, it's very important to recommend a high potassium diet, because one of the main functions of potassium intake is to promote the discharge of sodium, while potassium also has the function of softening blood vessels, so as to achieve the effect of lowering blood pressure.
3. Dietary fiber
Dietary fiber is indispensable to human health, which plays a very important role in maintaining the health of the digestive system. At the same time, taking enough cellulose can prevent cardiovascular disease, cancer, diabetes and other diseases; One of the biggest nutritional characteristics of black jujube is rich in dietary fiber, which on the one hand promotes gastrointestinal peristalsis, on the other hand increases the secretion of digestive fluid, so it plays a good role in moistening intestines and defecating, on the other hand, dietary fiber can also play a role in reducing blood lipid and blood sugar.
4, pectin
Pectin is a kind of polysaccharide polymer which constitutes the intercellular tissue of plants. Pectin has a good effect on lowering blood lipids. Cholesterol is one of the main components of blood lipids. Pectin has strong water absorption and is difficult to digest. Its gel properties can prevent cholesterol from contacting with digestive enzymes, bile acids and intestinal mucosa, while binding bile acids, thereby increasing the absorption of cholesterol. Big reduction.
5, Dan Ning
Tannin, also known as tannin, tannic acid or tannin, is one of the main differences between persimmons and other fruits and vegetables. Tannins belong to plant polyphenols, which can precipitate alkaloids, gelatin and other proteins. Tannin has both beneficial and harmful effects on human health. The beneficial aspect is that tannin has good antibacterial and antiviral effects, scavenging free antioxidant, anti mutation and anti-tumor effects, as well as lowering blood lipid and blood sugar. The adverse aspect is that tannin precipitation will interfere with the absorption of protein and some nutrients.
6. Yellow pigment
Although black jujube is black, the pigment separated from it is yellow. As a natural yellow pigment, the yellow pigment in jujube can not only be used as a pigment in the food industry, but also has a certain antibacterial effect. Of course, the research on this yellow pigment is still in its infancy, I believe that with the deepening of research, it will also reveal the more valuable effect of jujube yellow pigment.
