I caught this story while listening to on public radio a couple of weeks back about a recent discovery to come out of Rice University’s Dept. of Biochemistry and Cell Biology. A faculty professor there, Janet Braam, found that some produce, which in her experiments included cabbage, responded to light and dark cycles, known as circadian rhythms, days after being harvested. Cruciferous veggies such as cabbage use these cycles to produce cancer-fighting compounds. For nutritionists, grocers, and food distributors, this finding will likely have a significant effect on the way fruits and vegetables are handled. By regulating the light and dark cycles to mimic nature, they’ll be able to coax the maximum health benefits out of their produce.
