CHICAGO. Nano products are all the rage, even in food science. Here, at the Institute of Food Technologists’ annual meeting, on July 18, scientists described dramatic success in fighting food-poisoning bacteria by doctoring foods or their packaging with microbe-killing nanoparticles – sometimes along with natural anti-bacterial agents.
The nano of interest: Zinc oxide. When particles...
Each of us is a metropolis. Bustling about in everyone's body are tens of trillions of microbes. Some are descended from starter populations provided by mom during birth. Additional bacteria, yeasts, and other life forms hitchhike in with foods. By age 3, everyone's gut hosts a fairly stable, yet diverse, ecosystem.
Most of the tiny stowaways hide out in the...

And the really disturbing news: A new study finds that the age at which this common food allergy first shows...

From mid-August through September 2006, virulent bacterial infections sickened at least 204 spinach consumers. Five died and 30 others suffered acute kidney failure.
Among more than 3,500...
