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 rich in sugar and cyclic adenosine monophosphate, which can effectively protect the liver and cardiovascular system. Patients with flatulence and diabetes should not eat more. Patients with gastritis and gastric ulcer should peel raw dates when eating.

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 red dates is very high, a large amount of intake will stimulate the stomach and cause gastrointestinal discomfort. Dietary fiber mostly exists in jujube skin, which is thin and hard with sharp edges. If the gastric mucosa just has inflammation or ulcer, it will aggravate the pain and discomfort.

1, look at the color

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

Step 2 touch the texture

The skin of naturally mature winter jujube is smooth and hard, and the skin is closely attached to the pulp; However, the pericarp of saccharin jujube is sticky, even wrinkled, with loose epidermis and soft pedicel.
