Read the paragraph from the brochure about school lunches. Healthy school lunches—that is, meals that include fruits and vegetables, whole-grain foods, lean protein, and limited saturated fat and salt—should be the standard in our district. This would benefit the student body in several key ways. First of all, teaching children to eat healthy promotes positive eating habits through adulthood. Secondly, providing children with healthy food could help prevent issues such as diabetes and heart disease later in life. Lastly, healthy and hearty food boosts students’ energy, which can lead to improved focus and better grades.
