In the research, university scientists expose cell cultures of Chinese hamster lungs and ovaries to PCC components prepared by the ARS scientists. Then they challenge the cells with a chemical known to induce tumors. Later, they assess DNA breakage in the cells and identify the most protective PCCs. In preliminary studies, mice fed certain PCC components seem to be protected from some forms of cell damage. These components, not yet detailed in scientific literature, include molecules that are much more antimutagenic than flavonoids.
Flavonoids are antioxidants found in many foods.
The research, supported in part by the United Soybean Board , may serve as a model for research on other foods.
