How much benefit does cranberry extract have on the human body
Our intestines are a big garden with 1 trillion bacteria, some of which are beneficial and some of which are harmful. The food we eat also feeds the intestinal flora. Is there any food that can "kill two birds with one stone" and feed beneficial bacteria while eliminating harmful bacteria?
Cranberry extract, 4 days to improve gut health
A study published in the Nature journal npj Biofilms and Microbiomes found that taking cranberry extract in just four days can significantly increase the number of beneficial intestinal bacteria while reducing the number of harmful bacteria. Researchers at Laval University in Canada asked 28 healthy volunteers to take it for four consecutive days. They collected their stool samples before and after the supplementation period to analyze the composition of the intestinal microbiota.
The results showed that after just four days of cranberry extract supplementation, participants had an increase in Bifidobacterium, a type of beneficial gut bacteria, while a decrease in the number of a potentially harmful bacteria called Bacteroides.
Why?
This benefit may come from the prebiotics and polyphenols in cranberries. Cranberry extract contains a special oligosaccharide fiber called prebiotics. Prebiotics are "food" for probiotics. When bifidobacteria in the intestines break down and ferment these prebiotics, they will multiply in large numbers while reducing harmful bacteria, such as Bacteroides. In addition, researchers believe that the polyphenol compounds in cranberries have antibacterial properties, which help selectively kill bacteria that the human body does not need. Cranberry extract also increases the number of bacteria that produce butyrate, a short-chain fatty acid with a potent anti-inflammatory effect that helps maintain a healthy intestinal barrier. There is a correlation between a higher number of butyrate-producing bacteria and a lower risk of developing inflammatory bowel disease and even certain cancers. Analysis of blood and stool samples showed that after consuming cranberry extract for 4 days, the concentration of butyrate showed an upward trend.
The efficacy and effects of cranberry extract
- Bladder protection It is estimated that half of women and some men will suffer from a urinary tract infection at least once in their lifetime. For many people, this is troublesome and may sometimes recur. A study showed that people who consume cranberry extract daily can significantly reduce the risk of urinary tract infections.
- Protect the stomach and intestines Substances in cranberries can prevent bacteria from adhering to the stomach wall. Helicobacter pylori can cause gastric lining infections, gastric ulcers and intestinal ulcers, increasing the risk of stomach cancer. The anti-adhesion mechanism of cranberries promotes protection of the stomach and intestines.
- Anti-aging Cranberries are one of the fruits with the highest antioxidant content per calorie. Antioxidants protect cells from the free radicals that promote aging. Premature aging of the skin as well as diseases such as cancer and heart disease can be attributed to damage caused by free radicals.
- Cardiovascular protection Cranberries have many positive effects on the heart and blood vessels. Cranberries contain flavonol glycosides, which can prevent arteriosclerosis, which is the main cause of heart disease. Cranberries have a positive effect on cholesterol levels and can prevent arteries from narrowing due to the influence of certain enzymes, thereby promoting blood circulation.
Nutritional value of cranberry extract. Cranberry is not only rich in vitamin C, but also rich in phytochemicals, including anthocyanins, proanthocyanidins, ellagic acid, etc., which can be said to be a super antioxidant.
