New study: Green bananas have anti-cancer properties
Green bananas contain highly resistant starch that is resistant to digestive juices and has the properties of plant fiber.
Eating a banana a day can help prevent cancer. However, this only applies to unripe green bananas. The anti-cancer effect is due to the resistant starch contained in them, writes "Cancer Prevention Research", referring to the results of a British study.
Its authors, from the universities of Newcastle and Leeds, studied around 1,000 people with Lynch syndrome, a genetic disorder associated with an increased risk of cancer.
For the purposes of the study, participants took a daily dose of resistant (indigestible) starch equivalent to one unripe banana or a placebo for two years.
The results of the study show that resistant starch can change the type of bacteria in the gut and reduce the risk of tumors in the stomach, esophagus, pancreas and duodenum. In addition to bananas, it is found in beans and oats.
