Imported Foods Concern Food Safety Experts
August 21, 2007 02:11 PM - University of Georgia

A University of Georgia expert says the challenges in ensuring a safe U.S. food supply will continue to grow to unprecedented heights unless solutions are provided quickly. "Although most foods Americans eat are safe, with odds of greater than 1 in 1 million of becoming hospitalized from a serving of food, the dynamics of the U.S. food system are rapidly changing," said Michael Doyle, director of the UGA Center for Food Safety. "Consumers are much more vulnerable now to large episodes of foodborne illnesses."

New Study: Compound In Broccoli Could Boost Immune System
August 21, 2007 01:31 PM - By Sarah Yang, UC berkeley

A compound found in broccoli and related vegetables may have more health-boosting tricks up its sleeves, according to a new study led by researchers at the University of California, Berkeley. Veggie fans can already point to some cancer-fighting properties of 3,3'-diindolylmethane (DIM), a chemical produced from the compound indole-3-carbinol when Brassica vegetables such as broccoli, cabbage and kale are chewed and digested. Animal studies have shown that DIM can actually stop the growth of certain cancer cells.

August 20, 2007 05:54 PM - Julie Steenhuysen, Reuters

A common virus caused human adult stem cells to turn into fat cells and could explain why some people become obese, U.S. researchers said on Monday. The research builds on prior studies of adenovirus-36 -- a common cause of respiratory and eye infections -- and it may lead to an obesity vaccine, they said.
