Can we say goodbye to unreliable food diaries and diet recall in exchange for a urine test that will better aid researchers in figuring out what foods might help prevent cancer?
Georgetown researchers have developed a method that can quickly evaluate specific food compounds in human urine.
The new urine test looks for specific members of the isothiocyanates (ITCs) family (among other compounds), found in cruciferous vegetables. Animal and cell studies have shown that different types of ITCs have varying anticancer properties and potency, suggesting they are not equal
in protecting against cancer, Dyba says. “We developed our test because there has been no way to find out which specific ITCs works best,” he says.
For their study, the researchers focused on cruciferous vegetables, which showed a protective benefit against lung cancer in a study of more than 63,000 people who participated in the National Institutes of Health’s Singapore Chinese Health Study. Cruciferous vegetables, a major food in the Asian diet, include cabbage, Brussels sprouts, broccoli, cauliflower, bok choy and watercress, among others.
