Winter jujube contains many kinds of amino acids and vitamins needed by human body, especially vitamin C, which can improve human immunity and prevent colds. In addition, it is also rich in sugars and cyclic adenosine monophosphate, which can effectively protect the liver and cardiovascular system. Patients with flatulence and diabetes should not eat more, and patients with gastritis and gastric ulcer should peel raw dates when eating them.

Winter jujube is known as a natural "vitamin pill", but fresh jujube should not be eaten too much, otherwise it will hurt the stomach. Because the dietary fiber content of jujube is very high, a large intake will stimulate the stomach and cause gastrointestinal discomfort. Dietary fiber mostly exists in the jujube skin of jujube, and the jujube skin of jujube is thin and hard with sharp edges. If the gastric mucosa just has inflammation or ulcer, it will aggravate the pain and discomfort.

Selection skills:

1, look at the color

Naturally mature winter jujube gradually changes from cyan to red, so it is mostly green and deeply red, and there is no obvious dividing line between green and red; However, the winter jujube soaked in saccharin is mostly dark red or dark yellow, which is obviously different from the cyan part.

2. Touch the texture

The skin of naturally mature winter jujube is smooth and hard, and the peel and pulp are closely attached; However, the skin of saccharin jujube is sticky, even wrinkled, the skin is loose and the fruit pedicle is soft.

3. Taste it

Naturally ripe winter jujube is crisp and refreshing, with the sweetest flesh, tasteless peel and natural fragrance; Because of soaking, the peel of saccharin jujube is sweeter than the pulp, and the aftertaste is slightly bitter, and the washed water is also sweet.
