Studies have not established the effect of plums on breast cancer


Plums are a good dietary source of vitamin A and vitamin C and various carotenoids, anthocyanins and phenolics (including chlorogenic acid and glycosides of cyanidin, peonidin, and quercetin). Plums also contain fiber and potassium, as well as some magnesium and boron. Plums have been shown to possess antioxidant and anti-inflammatory properties. Chlorogenic acid has been shown to decrease anxiety in mice. Laboratory rats that drank plum juice had improved working memory in a water maze in one experiment. Plums have substantial bile acid binding potential, which has been associated with lower cholesterol and lower risk of heart disease and cancer.

Dried plums (prunes) are a good source of soluble fiber, ursolic acid and vitamin K. Prune consumption has been shown to improve bone health by improving bone density and strength.

Cancer-related effects of eating plums

Plum extract has been shown to decrease the proliferation of breast cancer cells. Plum extract also has been shown to induce apoptosis and reduce viability of human liver cancer cells. Plum consumption has been found to be associated with reduced risk of head and neck cancer. Purple and dark red plums contain anthocyanins, including cyanidin-3-glucoside, which has been shown to possess both chemopreventive and chemotherapeutic activity and to enhance the treatment effects of Herceptin.

Additional comments

Non-organic plums must be washed thoroughly to remove pesticide residue. Anthocyanin and phenolic content and antioxidant activity is higher in plums with dark skin and flesh than in lighter colored plums, and is also higher in the peels than in the flesh of plums.
