It's a recommended practice

"Let's face facts. The whole low-carb craze is playing itself out. The USDA recommends that every day we eat 6 to 11 servings of bread, cereal, rice, pasta, and other foods containing grains, especially whole grains. Bread is not the enemy of a healthy body, if you select the right bread.

The American Dietetic Association recommends a minimum of three servings of whole grains per day and goes so far as to recommend whole-wheat toast with peanut butter as a quick and healthy breakfast option."
