Winter jujube is a fresh-eating jujube variety newly developed in recent years. As a new variety grafted from sour jujube and large jujube, it is characterized by early fruiting, high yield, disease resistance, excellent quality, and unique flavor. Winter jujube is a high-quality fresh fruit, and it is currently the season for picking and consuming it.
Winter jujube is not only delicious for fresh eating, with a crispy skin, tender flesh, juicy and pulp-free, sweet and fragrant, but also extremely nutritious. Fresh jujube contains 20%-36% sugar; it contains 19 essential amino acids for the human body, such as aspartic acid, threonine, and serine. The most prominent feature of winter jujube is its extremely high vitamin C content, with 380-600 mg of vitamin C per 100 grams of flesh (a vitamin C supplement generally provides about 60 mg). This is 70 times that of an apple and 16 times that of a citrus. Even hawthorn, which was previously considered rich in vitamin C, is left in the dust.
Winter jujube is recognized as the best quality among the 261 fresh-eating jujube varieties, hence it has the reputation of a "living vitamin pill." Vitamin C is a powerful antioxidant and the best weapon against free radicals and aging. It can reduce melanin and inhibit its production, which can help fade existing spots and pigmentation and improve skin tone. It is often used in clinical treatments for whitening. Therefore, it is absolutely true that winter jujube can beautify the skin.
1. Detoxification and liver protection. Jujube is rich in sugars, vitamin C, and cyclic adenosine monophosphate (cAMP), which can reduce the damage of various chemical drugs to the liver. It can also promote liver protein synthesis, increase serum hemoglobin and albumin levels, adjust the albumin-to-globulin ratio, and lower serum alanine aminotransferase levels. Clinically, jujube can be used as an adjuvant treatment for chronic hepatitis and early cirrhosis.
2. Prevention and treatment of cardiovascular diseases. In addition to being rich in vitamin C and vitamin P, winter jujube also contains more vitamins A and E, as well as various trace elements such as potassium, sodium, iron, and copper. It is very beneficial for strengthening capillaries, maintaining the elasticity of blood vessel walls, and resisting atherosclerosis. Winter jujube also contains rutin, an effective ingredient for treating hypertension. Therefore, it is very helpful in the prevention and treatment of coronary heart disease, hypertension, and atherosclerosis.
3. Immune regulation. Modern scientists have also discovered that winter jujube contains high levels of substances such as cyclic adenosine monophosphate (cAMP). cAMP is an important bioactive substance that participates in various physiological activities in the human body. It can regulate the immune system, enhance myocardial contractility, protect the coronary arteries, lower cholesterol, and inhibit the proliferation of cancer cells. (Source: 39 Health Net)
