Emphasizes the relationship between health and nutrition to prepare nursing professionals for total patient care.

Functions of Nutrition

Maintains life and supports optimal health.
Nutritional science is integral in preventing diseases and modifying diets for therapeutic purposes.

Nutrient Classification

Nutrients are categorized by function:
- Body-building nutrients (e.g., proteins) vs. energy-providing nutrients (e.g., fats, carbohydrates).
Based on chemical properties: organic (proteins, fats, carbohydrates, vitamins) vs. inorganic (minerals, water).
Classification by essentiality: essential nutrients significantly support physiological functions.
Concentration varies; some nutrients are needed in larger amounts while others are required in smaller quantities.

Key Definitions

Nutrition: The science focusing on how food is utilized by the body for energy, growth, and maintenance.
Food: Organic or inorganic substances that nourish the body; crucial for survival alongside oxygen.
Diet: The balance and sequence of meals consumed daily.
Enzymes: Organic catalysts that accelerate chemical reactions in the body.
Hormones: Substances regulating vital processes, produced by endocrine glands.
Optimal nutrition: Achieving the highest level of health by receiving essential nutrients.
Health: A holistic concept, involving wellness beyond the mere absence of disease.
Public health: Focuses on community health improvement.
Holistic health: Considers the entire individual in health promotion.
Medical nutrition therapy (MNT): Nutritional treatment by registered dietitians for specific medical conditions.

Malnutrition

Malnutrition occurs due to inadequate nutrient intake or metabolism issues, leading to physical developmental delays or diseases like anemia and rickets.
Excess consumption can lead to obesity and related illnesses.

Nutrients Overview
