Dakota soils may be one the keys to preventing cancer.
They are high in selenium and crops grown on the soils may contain high concentrations of seleniums. In theory, foods producing from high-selenium grains may help prevent cancer.
The topic is the subject of a research symposium going on this week at the Grand Forks, N.D., Human Nutrition Research Center.
The South Dakota Wheat Commission is in the final phase of a feasibility study on the marketing of wheat naturally high in selenium.
