Medical value
Cranberry has been used as an adjuvant for anti-cystitis and urinary tract infection, its therapeutic effect has been widely recognized, in addition, cranberry also contains hypericin, five hydroxyl flavonoids, anthocyanins and other beneficial active ingredients for the human body.
1. Prevent urinary tract infections
The most unique effect of cranberry is to effectively prevent urinary tract infection (UTI), urinary tract infection 80% ~ 90% is caused by Escherichia coli, domestic and foreign scholars have studied the functional mechanism of this for many years, early people have always believed that cranberry in various acidic substances can increase the acid value of urine in the bladder, the formation of a strong acidic environment to kill Escherichia coli in the urethra. Proanthocyanidins are concentrated tannic acids, mainly oligomers or polymers of epicatechin and epicallocatechin, and the content of proanthocyanidins in cranberries is 34.3 mg/100 g. A large number of studies have shown that it has anti-bacterial adhesion properties, can prevent E. coli and other pathogenic bacteria from adhering to the urethral epithelium and bladder wall, and the pathogenic bacteria flow away with the urine, thus preventing the occurrence of urethral infection.
2. Anti-helicobacter pylori
Cranberry contains proanthocyanidins, ellagic acid, phenolic acid, resveratrol and other substances, has antibacterial effect. Many studies have shown that cranberries can inhibit the infection of helicobacter pylori, and have a good effect on the prevention of gastric ulcer, stomach cancer, and duodenal ulcer.
3. Antioxidant
Flavonoids in cranberry have antioxidant function in vivo and in vitro, especially flavonols and proanthocyanidins have preventive effect on atherosclerosis
4. Prevention of cardiovascular disease
Cranberries contain a variety of flavonols such as hypericin, pentahydroxyflavone, and myricetin, which together with anthocyanin determine the color of the cranberry fruit. Flavonols have strong antioxidant activity, can inhibit the oxidation of low-density lipoprotein cholesterol, reduce the level of triglycerides in the blood, and help promote the cardiovascular health of the human body
5. Protect your mouth and teeth
The study found that substances isolated from cranberry juice can protect teeth by breaking down bacteria in the mouth, specifically Streptococcus mutans in saliva, which can cause tooth decay and plaque
6. Lower blood pressure
The low sodium and high potassium properties of cranberries make them effective in lowering blood pressure. Studies have found that cranberry juice can promote the production of nitric oxide in blood vessel endothelial cells, which relaxes blood vessels, thereby lowering blood pressure. This helps explain how bilberries can help promote healthy blood pressure levels. Cranberry extract has antioxidant properties that can lower blood pressure and prevent diabetes.
7. Health effects
Cranberries also have a variety of other health functions, such as moistening bowel, lowering cholesterol, preventing heart disease, preventing arteriosclerosis, with antioxidant, anti-tumor, antiviral functions, liver protection, anti-ulcer and so on.
