dried prunes, dried plums

Dried plums, also known as prunes, are famous for their effects as a remedy for constipation. Now researchers working with rats have found that a diet rich in dried plums also appears to reduce the risk of colon cancer.

Changing the Balance of Gut Microbes:

The rats in the study were randomized to get a diet including prunes or one with equal calories, fat and protein but no dried plums. At the end of the study, the rats who had been consuming the dried fruit had a different balance of gut bacteria, with more of the phylum Firmicutes and fewer of the phylum Bacteroidetes.

The ecology of the gut bacteria are thought to play an important role in whether a person develops colon cancer, with Firmicutes being more protective. Apparently the phenolic compounds in the dried plums have antioxidant activity and help encourage the shifting balance of gut flora.

Healthier Colon Tissue:

In addition, the rats eating the prunes had fewer precancerous changes called crypts in their colon tissue. While we still don’t know if eating dried plums will help protect humans from colon cancer, it should at least make bathroom visits easier.

    3 prunes provide 3 mg of Boron whichis essential for bone health in conjunction with calclium. Strontium also helps with bone health:
    Strontium rich foods include unrefined whole grains, seafood, spinach, lettuce, carrots, peas, beans and celery. Strontium is found in highest amounts in the soil so root vegetables contain high amounts as does water that is untreated such as well water

    Regarding prunes – does this apply to eating the dried prunes or stewing the dried prunes? Or, does it make a difference?

    I eat prunes for two reasons. They do help with constipation and, hopefully, bone density.
    Some time ago, I read that prunes can help with bone density and then I saw that information again in a publication. I believe that the first place that I saw it was in People’s Pharmacy? Either way, it is part of my daily fruit intake.
