5. Cranberry Extract Powder benefits

a. Prevent urinary tract infection

The most unique effect of cranberry is that it can effectively prevent urinary tract infections (UTI). 80% to 90% of urinary tract infections are caused by E. coli. Scholars at home and abroad have been studying the mechanism of this function for many years. Various acidic substances in cranberry can increase the acidity of urine in the bladder, and the strong acidic environment formed can kill E. coli in the urethra. In 1998, a research report by Howell AB, a scientist at the State University of New Jersey, et al. confirmed for the first time that the active substance in cranberry that is responsible for inhibiting urinary infections is the concentrated tannins or proanthocyanidins (PACs) isolated from cranberries. Procyanidins are concentrated tannins, mainly oligomers or polymers of epicatechin and epigallocatechin. The content of proanthocyanidins in cranberry is 34.3 mg/100 g. A large number of studies have shown that it has anti-bacterial adhesion properties and can prevent pathogenic bacteria such as Escherichia coli from adhering to the epithelial cells of the urethra and the bladder wall. The pathogenic bacteria flow away with the urine, thereby preventing the occurrence of urinary tract infections.

b. Helicobacter pylori

The proanthocyanidins, ellagic acid, phenolic acid, resveratrol and other substances contained in cranberries have antibacterial effects. Many studies have shown that cranberry can inhibit Helicobacter pylori infection and has a good effect on preventing gastric ulcer, gastric cancer, and duodenal ulcer.

c. anti-oxidation

The flavonoids in cranberry have antioxidant functions in in vivo and in vitro tests, especially flavonols and procyanidins have a preventive effect on atherosclerosis.

d. Prevent cardiovascular disease

Cranberry contains hyperoside, quercetin, myricetone and other flavonol compounds, which together with anthocyanins determine the color of 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 body’s cardiovascular health.

e. Protect the mouth and teeth

Studies have found that the substances isolated and extracted from cranberry juice can decompose the flora in the oral cavity, especially the streptococcus mutans in the saliva that can cause dental caries and dental plaque, thereby protecting the teeth.

f. hypotensive

The low sodium and high potassium properties of cranberry make it have the effect of lowering blood pressure. Studies have found that cranberry juice can promote vascular endothelial cells to produce nitric oxide, relax the blood vessels, thereby lowering blood pressure. This helps explain how bilberries can help promote healthy blood pressure levels. Apostolidis et al

The water-soluble cranberry extracts were fused with oregano, rosemary, and rhodiola as raw materials, and their inhibitory effects on α-glucosidase, pancreatic α-amylase and ACE-1 were determined to evaluate their resistance. Oxidative activity, as well as the effect on diabetes and antihypertensive effect. The results showed that the ability of different components to inhibit α-glucosidase, pancreatic α-amylase and ACE-1 after being combined with cranberry extract was significantly enhanced, indicating that cranberry extract has antioxidant properties, lowering blood pressure and Prevent diabetes.

g. Other health functions

Cranberry also has many other health functions, such as laxative bowel movement, lower cholesterol, prevent heart disease, prevent arteriosclerosis, have antioxidant, anti-tumor, anti-viral functions, protect the liver, and fight ulcers.

A: Cranberry might decrease how quickly the body breaks down atorvastatin (Lipitor).
