Study Notes
Definition and Overview
- Nutrition integrates knowledge to maintain well-being from birth to death through effective education.
- Nutrition is the science studying the composition of food, nutrients, and their impact on health.
- Food nourishes the body, aiding in tissue repair, energy supply, and regulation of bodily processes.
Key Nutritional Components
- Nutrients are essential chemicals that serve three main functions:
- Provide energy for biochemical reactions.
- Build and repair tissues, including organs and bones.
- Regulate life processes for homeostasis.
- Classifications of nutrients include:
- Energy-providing (Go Food).
- Body-building (Grow Food).
- Body-regulating (Glow Food).
Nutritional Status
- Nutritional status (nutriture) reflects the body's condition based on nutrient utilization.
- Categories include:
- Optimum or good nutrition: Adequate supply and effective use of essential nutrients.
- Malnutrition: Includes undernutrition (deficiencies), overnutrition (excesses), and nutrient imbalances.
Malnutrition and Its Forms
- Malnutrition refers to imbalances in nutrient intake leading to health issues.
- Forms include:
- Undernutrition: Insufficient intake, leading to wasting (low weight-for-height), stunting (low height-for-age), underweight, and deficiencies.
- Overnutrition: Excessive energy intake leading to overweight or obesity, classified using Body Mass Index (BMI).
Overnutrition
- Overweight defined as a BMI of 25+, obesity as a BMI of 30+.
- Associated with diet-related noncommunicable diseases (NCDs) such as cardiovascular diseases, certain cancers, and diabetes.
Micronutrient Malnutrition
- Deficiencies in vitamins and minerals can hinder the body's ability to produce essential enzymes and hormones.
- Common deficiencies include iodine, vitamin A, and iron, crucial for global health, especially in low-income populations.
Imbalance Nutrition
- A pathological state results from disproportions among essential nutrients, affecting metabolic needs without absolute deficiencies.
Dietary Standards
- Provide nutrient requirements for good health specific to age, sex, weight, and physical activity.
- Recommended Energy/Nutrient Intake (REI/RNI) serves as guidelines for maintaining health.
Food Quality
- Defined as the degree of excellence based on consumer satisfaction and fitness for consumption.
- Factors determining food quality include:
- Identity and quantity of food.
- Sensory attributes (taste, texture).
- Shelf-life stability, wholesomeness, and packaging.
Factors That Affect Food Choices
- Environmental factors:
- Macro-level includes broader societal influences.
- Physical environment affects where food is procured or consumed.
- Social environment influences preferences and availability.
- Individual-level factors shape personal food choices based on personal preferences and experiences.
