As one of persimmon foods, black dates certainly have the same characteristics as persimmon foods 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 preventing gingival atrophy to relieving arteriosclerosis, from scavenging free radicals to improving immunity and anti-cancer, vitamin C is needed everywhere. It is no exaggeration to say that without vitamin C, there would be no life!

bring down the blood pressure

The mineral content of black dates is also quite rich, especially the potassium content is very high and the sodium content is much lower, which is very important for controlling blood pressure and maintaining heart health. Because a long-term high-salt diet can lead to high blood pressure. Although experts suggest that each person's daily salt intake should not exceed 6 grams, most people can't do it in real life. Therefore, it is very important to recommend a high-potassium diet, because one of the main functions of potassium intake is to promote sodium excretion, and potassium also has the effect of softening blood vessels, thus achieving the effect of lowering blood pressure.

Reduce blood lipid and blood sugar

Dietary fiber is indispensable to human health and plays a very important role in keeping the digestive system healthy. At the same time, taking enough fiber can prevent cardiovascular diseases, cancer, diabetes and other diseases. One of the biggest nutritional characteristics of black dates is that they are rich in dietary fiber. On the one hand, dietary fiber promotes gastrointestinal peristalsis, on the other hand, it increases the secretion of digestive juice, so it plays a good laxative role. In addition, dietary fiber can also reduce blood fat and blood sugar.

Lowering blood lipid

Pectin is a polysaccharide polymer that constitutes the intercellular tissue of plants. Pectin has a good hypolipidemic effect. Cholesterol is one of the main components of blood lipids. Pectin is absorbent and difficult to digest. Its gel characteristics can prevent cholesterol from contacting digestive enzymes, bile acids and intestinal mucosa, and combine bile acids at the same time, thus greatly reducing the absorption of cholesterol.

Antibacterial and antiviral, scavenging free radical oxidation, anti-mutation and anti-tumor

Tannin, also known as tannic acid, tannic acid or tannin, is one of the main differences between persimmon and other fruits and vegetables. Tannin belongs to plant polyphenols, which can precipitate protein such as alkaloids and gelatin. Tannin has both advantages and disadvantages to human health. On the one hand, it has good antibacterial and antiviral effects, scavenging free antioxidants, resisting mutation and tumor, and lowering blood lipid and blood sugar. On the other hand, the precipitation of tannin will interfere with the absorption of protein and some nutrients.

Antibiotic action

Although black dates are black, the pigment component separated from them is yellow pigment. As a natural yellow pigment, the yellow pigment in black dates can not only be used as a pigment in food industry, but also has a certain antibacterial effect. Of course, the research on this yellow pigment is still in its infancy, and I believe that with the deepening of the research, it will definitely reveal the more valuable effects of black jujube yellow pigment.
