Suppose that two recent studies conclude that increased fiber in the diet does not reduce the risk of developing colon cancer as was previously thought. The likely result will be that the: A. quantity demanded of high-fiber foods will fall. B. demand for high-fiber foods will decrease. C. supply of high-fiber foods will increase. D. price of high-fiber foods will rise

B. demand for high-fiber foods will decrease.

The demand of high fiber food will decrease because many people were taking the high fiber food because of its medicational property of preventing cancer. So after this report, these people will reduce buying the high -fiber food which will result in reducing demand for high fiber food. Therefore the right answer is B.
