Jujube health care
The vitamin C content of jujube is the highest among all fruits, which is 80 ~ 90 times higher than that of apple and peach, and about 140 times higher than that of pear. Known as "natural vitamin C pills". In recent years, scientists have found that red dates also contain many other essential substances, which have many new health functions:
Allergy: In China, people use red dates to treat allergic purpura, three times a day, each time 10 pills, generally effective for three days. Later, Japanese scientists found that jujube contains a lot of substances called cyclic adenosine monophosphate, which has the functions of dilating blood vessels, resisting allergy, enhancing myocardial contractility and improving myocardial nutrition.
Anti-cancer: Jujube is rich in triterpenoids (such as maslinic acid) and adenosine diphosphate. Triterpenoids have the effect of inhibiting cancer cells, among which maslinic acid has the strongest ability, surpassing the commonly used anticancer drug fluorouracil. Although adenosine diphosphate does not have the ability to inhibit cancer cells, it can regulate cell division. As a result of the synergistic effect of the two, the abnormal proliferation of cancer cells can be divided to a degree beyond normal. Animal experiments have also proved that the percentage of malignant tumors in the digestive tract of animals with red dates is only half of that of animals without red dates. Therefore, while applying other anti-tumor measures, tumor patients can take the food made of red dates every day, which not only has anti-tumor effect, but also has the functions of benefiting qi and nourishing blood, strengthening the body and reducing the side effects of radiotherapy and chemotherapy.
Liver protection: Experiments and clinical trials have proved that red dates can increase the contents of total protein and albumin in serum. Clinical reports show that for patients with acute and chronic hepatitis, liver cirrhosis and patients with high serum transaminase activity, taking Jujube Peanut Soup (30g of jujube, peanut and rock sugar each, stir-frying peanuts first, then adding jujube and rock sugar) 1 dose every night before going to bed, and the course of treatment is 1 for 30 days, which can reduce the serum alanine transaminase level.
Relieve the medicinal properties: adding red dates to some prescriptions with strong medicinal properties can alleviate the medicinal properties and avoid serious drugs from harming people's health.
Rehabilitation: British scientists have done experiments in 163 weak patients. Those who eat dates continuously recover more than three times faster than those who only eat vitamins. Jujube has anti-fatigue effect and can enhance people's endurance. Besides, cooking glutinous rice porridge's regular food with red dates and pig bones is a good food supplement, which can nourish yin and replenish blood, especially suitable for blood diseases and the elderly.
It is worth noting that the sweet taste of jujube helps to eliminate dampness and qi, and it is easy to have bloating if you eat too much. Use with caution those who have symptoms such as phlegm and bloating.
