Human Nutrition: A Core Component of Nursing Education
Human nutrition, a vital aspect of the Bachelor of Science in Nursing (BSN) curriculum, focuses
on the relationship between diet, health, and disease. This knowledge is essential for promoting
wellness, preventing malnutrition, and managing diet-related illnesses. Nurses, as frontline
healthcare providers, play a crucial role in educating individuals and communities about proper
nutrition and its impact on overall health.
Macronutrients: Energy Sources and Functions
Macronutrients provide the body with energy and are essential for growth, repair, and
maintenance.
• Carbohydrates: The primary energy source for the body, carbohydrates are found in
foods like rice, bread, fruits, and vegetables. Simple carbohydrates (e.g., glucose) provide
quick energy, while complex carbohydrates (e.g., whole grains) offer sustained energy
and dietary fiber, which supports digestive health.
• Proteins: Essential for tissue repair, immune function, and enzyme production, proteins
are found in meat, fish, eggs, beans, and dairy. For example, patients recovering from
surgery require increased protein intake to promote wound healing.
• Fats: Serve as an energy reserve and are crucial for the absorption of fat-soluble vitamins
(A, D, E, and K). Healthy fats, such as those from avocados, nuts, and olive oil, reduce
the risk of cardiovascular diseases, while trans fats should be minimized to avoid adverse
effects on heart health.
Micronutrients: Vitamins and Minerals
Micronutrients are required in small amounts but are essential for proper physiological function.
• Vitamins: Each vitamin has specific roles. For instance:
