Principles of Nutrition Review
Questions
Course Introduction
Principles of Nutrition introduces students to the fundamental concepts of human nutrition, exploring the physiological roles, sources, digestion, absorption, and metabolism of essential nutrients including carbohydrates, proteins, fats, vitamins, and minerals. The course examines how nutrition influences health and well-being across the lifespan, the relationship between diet and chronic diseases, dietary guidelines, food labeling, and the ethical, cultural, and environmental factors affecting food choices. Students will develop a foundational understanding of nutritional science, practical applications for healthy eating, and critical thinking skills necessary to evaluate nutrition information in a rapidly changing world.
