With the participation of vitamin C, it is no exaggeration to say that without vitamin C, there is no life!
2. The mineral content of potassium is also very rich. In particular, the potassium content is very high, and the sodium content is relatively low. This is very important for controlling blood pressure and maintaining heart health. Long-term high-salt diet can lead to high blood pressure. Although experts recommend that people eat no more than 6 grams of salt per day, but the absolute majority of people can not do in real life, so the recommendation of high potassium diet is very important, because one of the main role of potassium intake in the human body is Promote the discharge of sodium, while potassium also has the effect of softening blood vessels, so as to achieve the effect of lowering blood pressure.

5. Tannin tannins, also known as tannins, tannic acid or tannins. One of the main differences between persimmons and other fruits and vegetables is the very high tannin content. Tannins are plant polyphenols that precipitate alkaloids, gelatin, and other proteins. Tannins have both beneficial and harmful effects on human health. The beneficial aspect is that tannins have good anti-bacterial and anti-viral activities, free anti-oxidation, anti-mutagenicity, anti-tumor, and hypolipidemic and hypoglycemic effects. The sedimentation of tannins interferes with the absorption of proteins and certain nutrients.
Although the yellow pigment is black, the pigment component isolated from it is yellow pigment. The yellow pigment in black jujube is a natural yellow pigment, not only can be used as a pigment in the food industry, but also found that it has a certain antibacterial effect.
