ABSTRACT

Polyphenol-rich foods, such as pomegranate, green tea, turmeric, and broccoli have demonstrated anticancer effects in laboratory studies. In humans, observational studies have linked their intake with a lower risk of chronic disease, including cancer. Concentrating these foods into a capsule is a convenient way to boost an individual’s polyphenol intake but hitherto adequately powered double blind randomized controlled trials have not fi rmly established that this benefi ts health or markers of cancer progression.
