Narrator: This is Science Today. It's often assumed that the older you are, the harder it is to break bad habits, especially when it comes to diet. But Cheryl Rock, a professor of Family and Preventive Medicine at the University of California, San Diego says that's not necessarily the case.
Rock: We think that with what we know about individualizing and food choices, that it's possible to change your diet at any age.
Narrator: Working with an older population, Rock and her colleagues have designed a dietary intervention program called the APPLE study, which emphasizes more vegetable and fruit intake to reduce the risk of the recurrence of a colonic polyp, which may be a precursor to colon cancer.
Rock: Our average participant in the APPLE study is someone who's in their sixties and seventies and often retired and they don't want to spend a lot of time at home cooking. And so, that's a study in which we emphasize a lot of convenient ways that you can get this kind of a healthier diet. And the outcome is that we can prevent the recurrence of colon polyps, which have been in turn related to the greater likelihood of developing colon cancer.
