Heading: The Importance of a Balanced Diet

Chapter 2 also emphasizes the significance of a balanced diet in maintaining optimal health. A balanced diet includes a combination of different food groups in appropriate proportions to provide all essential nutrients. Students learn about the USDA’s MyPlate guidelines, which divide the plate into sections representing fruits, vegetables, grains, protein, and dairy, giving an idea of the relative proportions each should occupy in a daily diet.

Factors influencing food choices are also discussed in this chapter. These include cultural, societal, economic, and personal factors such as preferences, allergies, and dietary restrictions. Understanding these factors helps students make conscious and informed decisions about their food choices.
