Washington CNA Practice Exam: Complete Practice Test & Study Guide

Whole wheat bread is an example of a whole grain food because it is made from whole grains that retain all parts of the grain — the bran, germ, and endosperm. This means it contains more fiber, vitamins, and minerals compared to refined grains, which have been processed to remove the bran and germ.

Whole wheat bread provides more nutritional benefits, as it helps in digestion, supports heart health, and maintains steady energy levels. In contrast, white bread is made from refined grains, which lose many nutrients during processing. Bagels and pasta can be made from whole grains, but if they are specifically made from refined flours, they wouldn't qualify as whole grain foods. Therefore, whole wheat bread stands out as a clear example of a whole grain option.
