Whole grains can be found in boring barley and wild rice, but now, Kraft is making it easier to get the recommended daily dose of the heart-healthy grain by adding it to more than 100 of its products.

Kraft Foods Inc. announced Monday it will more than double the amount of whole grains in many of its Nabisco crackers in the next three years.

Whole grains are part of a healthy diet, and according to the Mayo Clinic, are a better source of fiber and other important nutrients, including selenium, potassium and magnesium, than refined. Whole grains help reduce the risk of heart disease, improve digestion, provide essential nutrients and help control weight, according to the U.S. Department of Agriculture.

The USDA recommends getting six to 11 servings of grains per day, half of which should be whole.

In light of consumer and health advocates' demands for improved nutrition from packaged foods, Kraft plans to change the recipe of its Ritz and Premium crackers to contain whole grains for the first time. They also plan to more than double the amount of whole grains in Wheat Thins crackers and Honey Maid graham crackers, according to ABC News.

Kraft currently uses whole grains in Triscuits, and increased the amount of whole grains in some Wheat Thins products last summer. As a result of the changes, some products, such as Original Wheat Thins and Honey Maid original, will use only whole grains.

"People are looking for more whole grains, we know that they aren't getting enough," said Carlos Abrams-Rivera, vice president of the Nabisco Crackers business, to ABC.
