Cranberry powder is mainly a kind of food made from fresh cranberries after dehydration. It is very rich in nutritional value and contains a lot of polyphenols, which can effectively enhance the body's immunity and prevent urinary tract infections. Moreover, there are more acidic substances in this cranberry, which can promote the secretion of digestive juice in the intestinal tract and increase appetite. Among them, vitamin c is a strong antioxidant, and there are a lot of flavonoids, which can effectively whiten the skin and promote skin metabolism.
1. Antibacterial effect
Cranberries contain a large amount of proanthocyanidins, flavonols and hydroxycinnamic acid, which in the human body can prevent the adhesion and aggregation of bacteria on the mucous membranes, and reduce the formation of biofilms, thereby reducing inflammation.
Antibacterial properties of proanthocyanidins in cranberry, related to their degree of polymerization and ratio of A-type/B-type bonds. Procyanidins with a high degree of polymerization can better inhibit the growth of Candida, while procyanidins with a higher proportion of A-type bonds also have better antibacterial effects and can more effectively inhibit the activity of bacteria.
Proanthocyanidins achieve antibacterial effects by interfering with bacterial aggregation in the early stage of infection, preventing bacterial reproduction and forming biofilms - the widespread hydroxyl structure in proanthocyanidins can promote the formation of intermolecular hydrogen bonds, making small molecules aggregate, and cell surface receptors Interaction, interfere with the adhesion of bacteria to each other, and hinder the formation of biofilms in the human body in the oral cavity, stomach, urinary tract, female vagina, small intestine and colon.
In the cranberry complex extract, there are also non-phenolic compounds such as isoprenoids, ursolic acid and xyloglucan, as well as active ingredients such as arabinosyl glucan, which can effectively prevent bacteria in combination with proanthocyanidins. Adhesion to epithelial cells and biofilm formation.
The metabolites of cranberry polyphenols in the colon, including hydroxylated benzoic acid and phenylacetic acid, can also effectively inhibit the adhesion of uropathogenic Escherichia coli and bladder epithelial cells and the formation of biofilms.
2. Regulate intestinal flora metabolism
The balance of gut flora is one of the key factors in human health, and they affect the availability and metabolism of food components. The integrity of the intestinal mucosal barrier provides effective resistance to harmful microorganisms in food and the environment.
If the intake of saturated fat and sugar in the daily diet is high, and the intake of fiber is low, it will lead to impaired intestinal mucosal barrier function, increased intestinal permeability, and easier entry of bacterial endotoxins into the body. Endotoxins enter the blood and tissues, stimulate innate immune responses in macrophages, neutrophils, endothelial cells, and adipocytes, and cause inflammation in the body.
Cranberry extract can relieve intestinal mucosal barrier dysfunction and chronic inflammation caused by unbalanced diet, and reduce the levels of inflammatory factors such as endotoxin and TNF-α in plasma.
3. Promote lipid metabolism
In an experiment involving 30 patients with type 2 diabetes, the patients took cranberry extract every day for 12 weeks, and their LDL and total cholesterol levels decreased.
4. Lower blood pressure
Research has shown that cranberry extract can help lower blood pressure. In the experiment, volunteers with obesity, type 2 diabetes, metabolic syndrome, and cardiovascular disease were supplemented with 346-835 mg of cranberry polyphenols daily over a period of time, with the increase of cranberry extract intake. increase, the systolic blood pressure decreased by an average of 3mmHg.
In volunteers without other medical conditions, daily low-dose cranberry extract supplementation for 8 weeks resulted in an average reduction in diastolic blood pressure of 4.7 mmHg.
5. Regulate blood sugar metabolism
In animal experiments, cranberry polyphenols have shown multiple regulatory effects on glucose metabolism—inhibiting the digestion and absorption of carbohydrates in the intestine, stimulating insulin secretion from pancreatic beta cells, and activating insulin receptors in insulin-sensitive tissues. Promote the absorption of sugar, and regulate the release of liver glycogen.
Clinical studies have also shown that increasing the intake of polyphenols from food sources (cranberry extract contains large amounts of polyphenols) can improve blood sugar control in patients with type 2 diabetes.
The effect of cranberry on human health is achieved through the active ingredients such as plant polyphenols. Compared with cranberry juice, dried fruit and jam, fresh cranberries and cranberry freeze-dried powder have higher content of active ingredients, and cranberry peels also have more active ingredients than pulp.
Since fresh cranberries are difficult to store for a long time and transported over long distances, whole cranberry freeze-dried powder/extract is the most convenient and effective option for maintaining the active ingredients of cranberries.
