Insufficient whole grain intake is the single largest dietary contributor to preventable cancer cases, followed by low dairy intake and high processed meat consumption.
Aim for 3 servings of whole grains daily. This specific factor contributes to the highest number of preventable cancer cases. Ensure at least half of your grain intake is whole grains, as recommended by federal guidelines.
