3. A source of nourishment; food
As a nation, we eat poor-quality foods that have been stripped of nutrients. We do not consume enough fresh fruits and vegetables. Many of us get our whole grains from instant rice, refined wheat breads, pastas, and cereal. We eat a tremendous amount of prepackaged, pre-made meals. One-quarter of Americans eat at fast food restaurants each day. Americans are overfed and undernourished.
