Study Notes

Nutrition and Health (ANT1005)

The course covers nutrition concepts and principles, including tutorial quizzes (10%), practical workshops, and topic-specific learning objectives.
Practical sessions involve nutrient calculations, focusing on the 4,4,9,7 rules and healthy eating plate models.
A specific dietary tutorial, and practical activity sessions are scheduled for 9 Dec (9:30am-10:30am) .

Introduction to Nutrition Concepts

Nutrition plays a vital role in health and well-being, influencing susceptibility to various diseases.
A proper diet is crucial for growth, development, maintaining a healthy weight, and preventing chronic diseases.
Understanding basic nutrition is essential, especially in preventing diseases and general health maintenance

Essential Definitions

Foods: Plant or animal products that provide energy and nutrients for the body.
Nutrients: Chemical substances in food, including energy-yielding (carbohydrates, proteins, fats) and non-energy-yielding (vitamins, minerals, water) components.
Nutrition: The study of nutrients in foods and their actions within the body (e.g., ingestion, digestion, absorption, transport, metabolism, excretion).

Categories of Nutrients

Macronutrients: Nutrients required in large amounts (carbohydrates, proteins, fats, water).
Micronutrients: Nutrients needed in smaller amounts (vitamins, minerals).
Organic Nutrients: Contain carbon atoms (carbohydrates, proteins, lipids, vitamins).
Inorganic Nutrients: Do not contain carbon atoms (minerals, water).
Energy-Yielding Nutrients: Provide energy (carbohydrates, proteins, fats).
Non-Energy-Yielding Nutrients: Do not provide energy directly (vitamins, minerals, water).
Essential Nutrients: Cannot be made by the body and must be obtained from food (e.g., water, vitamin A, iron).
Non-essential Nutrients: Can be made by the body. (e.g., cholesterol, biotin, vitamin D).

Functions of Nutrients

Provide energy.
Support growth, development, and body tissue repair.
Regulate bodily functions.
Reduce the risk of some illnesses.

Nutrient Calculations

Energy contribution from various nutrient types:
- Carbohydrates: 4 kcal/gram.
- Proteins: 4 kcal/gram.
- Fats: 9 kcal/gram.
- Alcohol: 7 kcal/gram.
Nutrient Analysis software (e.g., FoodWorks Xyris) helps with calculations for individual and population-level data.

Energy Density and Nutrient Density

Energy density refers to the amount of energy per gram of food.
Nutrient density relates to nutrients (vitamins/minerals) per calorie.
Empty calorie foods have higher energy density but low nutrient density.

My Healthy Plate

A visual guide for creating balanced meals.
A quarter of the plate is for rice and other alternatives.
Half should consist of meat and others
Half of the plate is for fruits and vegetables

Recommended Dietary Allowances (RDA)

Standardized daily nutrient intake guidelines for a healthy population, with varied intake needs for different age groups and genders.
Examples provided include calcium RDA for various age groups.

Methods of Analyzing Nutrients in Food

Chemical analysis: Precise method for identifying all nutrients and amounts, upon which food composition tables and software are based.
Food composition tables: Lists of nutrients for various foods, categorized based on food groups (e.g., milk, rice, fruit).
Nutrient analysis software: Uses chemical analysis data to calculate nutrient content and potentially assess requirements for individuals or populations.

Conclusion

A healthy diet, considering nutrient density and energy from food, helps manage weight and prevent chronic diseases by meeting nutritional requirements.
