Final answer:
The likely result of new scientific studies showing that high-fiber diets do not reduce the risk of colon cancer as previously believed is a decrease in the quantity demanded of high-fiber foods.
Step-by-step explanation:
According to new scientific studies, high-fiber diets do not reduce the risk of developing colon cancer as well as was previously thought.
In this scenario, the likely result would be that the quantity demanded of high-fiber foods will decrease. This means that people may be less inclined to purchase high-fiber foods since they are not as effective in reducing the risk of colon cancer.
