That’s right, the fruits. Breast cancer cells died after being treated with peach and plum extracts. And better still, the healthy cells were left unharmed.
David Byrne of AgriLife Research said of the findings:
"It was a differential effect which is what you're looking for because in current cancer treatment with chemotherapy, the substance kills all cells, so it is really tough on the body. Here, there is a five-fold difference in the toxic intensity. You can put it at a level where it will kill the cancer cells -- the very aggressive ones -- and not the normal ones."The research, published on Science Daily June 2nd, explained that phenolic (acidic) compounds present in fruit, coupled with the high antioxidant count makes them proficient in destroying cancer cells. Standard testing methods used to determine antioxidant levels present showed certain types of peaches and plums to be very high in antioxidants. Higher even than blueberries, the antioxidant super fruit. Tests also showed the compounds stopped cancer cells from growing.
"Rich Lady" peaches and "Black Splendor" plums are the two varieties AgriLife Research determined to be antioxidant rich, but went on to state that they may not be the highest. A study done by European Food Research and Technology in 2007 which tested three different types of peaches on antioxidant levels, Vitamin C, and ability to trap free radicals showed the "Luisa Berselli" peach to have superior free radical trapping ability. So, all peaches are not the same.
Peaches and plums are both high in Potassium, Phosphorus, Magnesium, Calcium, and Vitamins A, C, Niacin, and Folate. And with peaches receiving a high ranking on the Environmental Working Group’s Shopper’s Guide for produce containing pesticides (plums are 18th), these two fruits are best purchased organically grown.
