Study Notes

Nutrition Overview

Nutrition is the science of food, nutrients, and their effects on health.
It encompasses the processes by which organisms utilize materials for growth, maintenance, and energy.
Effective nutrition education contributes to nutritional well-being throughout life.

Definition of Food and Nutrients

Food refers to any organic or inorganic substance that nourishes the body, aiding in tissue building, energy supply, and bodily regulation.
Nutrients are essential chemical components enabling the body to generate energy, build tissues, and regulate functions.

Types of Nutrients

Three general functions:
- Provide Energy: Supports biochemical processes.
- Build and Repair Tissues: Necessary for organs and structures.
- Regulate Body Processes: Maintains balance and homeostasis.
Nutrients categorized by function:
- Go Food: Provides energy.
- Grow Food: Builds body tissues.
- Glow Food: Regulates bodily functions.

Nutritional Status

Nutritional status (nutriture) reflects a body's condition based on nutrient utilization.
Classifications include optimal nutrition, malnutrition, and nutrient inefficiencies.
Malnutrition entails deficiencies, excesses, or imbalances in nutrient intake.

Forms of Malnutrition

Undernutrition: Insufficient nutrient intake leading to:
- Wasting: Low weight-for-height.
- Stunting: Low height-for-age.
- Underweight: Low weight-for-age.
Overnutrition: Excessive nutrient intake leading to overweight and obesity.
Specific Nutrient Deficiency: Lack of essential vitamins or minerals.

Overnutrition and Health Risks

Overweight defined by a Body Mass Index (BMI) of 25 or more; obesity at 30 or more.
Diet-related noncommunicable diseases (NCDs) arise from unhealthy diets, including cardiovascular diseases and diabetes.

Deficiencies in vitamins and minerals hinder enzyme and hormone production.
Critical deficiencies include iodine, vitamin A, and iron, affecting health globally.

Imbalance Nutrition

Results from excess or insufficient intake of essential nutrients.
Imbalance states may occur without absolute nutrient deficiencies.

Dietary Standards and Requirements

Dietary standards provide minimum nutrient requirements for good health.
Recommended Energy Intake (REI) and Nutrient Intake (RNI) are recognized guidelines for maintaining health.

Food Quality Considerations

Food quality pertains to the degree of excellence in products, fitness for consumption, and consumer satisfaction.
Criteria include identity, stability, sensory attributes, wholesomeness, and proper packaging.

Factors Influencing Food Choices

Environmental and individual factors heavily impact food selection.
- Macro-level: Larger societal influences.
- Individual level: Personal preferences and needs.
