What the Research Says
The benefits of eating more whole grains are becoming clearer as scientists continue to examine the evidence.

In addition, the American Institute of Cancer Research suggests that diets rich in whole grains can reduce the incidence of certain types of cancer. Whole grains contain nutrients and compounds that can protect cells from damage that could lead to cancer. These include:
Eating more whole grains, fruits, vegetables, and beans could also reduce the amount of red meat and processed meat in our diet -– foods that are linked to increased cancer risk.
