A Cornell University researcher is making an even stronger case that an apple a day—as well as daily helpings of other fruits and vegetables—can help keep the breast-cancer doctor away.
Rui Hai Liu, an associate professor of food science at the Ithaca-based university, has published six studies on the subject in the past year.
He reports that fresh apple extracts significantly inhibited the size of mammary tumors in rats, according to a news release. The more extracts they were given, the greater the inhibition.
"We not only observed that the treated animals had fewer tumors, but the tumors were smaller, less malignant and grew more slowly compared with the tumors in the untreated rats,” he says.
The study confirmed a preliminary study in rats published in 2007.
In his latest study, Liu found that a type of adenocarcinoma—a highly malignant tumor and the main cause of breast-cancer patient deaths—was present in 81 percent of tumors in the control animals.
But it developed in only 57 percent, 50 percent and 23 percent of the rats fed low, middle and high doses of apple extracts, respectively, during the 24-week study. The diets were the equivalent of one, three and six apples a day in humans.
"That reflects potent anti-proliferative [rapid decrease] activity," Liu says.
The studies highlight the important role of phytochemicals, known as phenolics or flavonoids, found in apples and other fruits and vegetables. Of the top 25 fruits consumed in the United States, Liu says apples provide 33 percent of the phenolics that Americans consume annually.
His research was supported in part by the U.S. Apple Association.
NOTE: Since the apple is one of the "Dirty Dozen" , loaded with pesticides, it makes sense to contact your local apple grower and ask him'her about their growing practices. People of the Quinte may want to check with Grills Orchards, they are among the most trustworthy people to ask a question like that
