Introduction to Nutrition Review Questions
Course Introduction
Introduction to Nutrition provides a foundational understanding of the science of human nutrition, exploring the role of nutrients in the body and their impact on health and disease prevention. The course covers key topics such as macronutrients (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals), digestion and absorption, dietary guidelines, energy balance, and the relationship between nutrition and chronic illnesses. Students will also examine current issues in nutrition, evaluate diet trends, and develop skills to analyze and improve personal and community eating patterns for lifelong health.
