Study Notes
Understanding Food
- Food refers to substances consumed to support life and promote health, sourced from plants or animals.
- It can be eaten in natural form or processed in factories.
Importance of Food
- Essential for body functions, growth, and development.
- Energy derived from food measured in kilocalories (Kcal).
What is Nutrition?
- Nutrition is the process of obtaining food required for health, involving ingestion, digestion, absorption, and utilization of nutrients.
- Key substances in food necessary for proper body function are called nutrients.
Types of Nutrients
- Macronutrients, including carbohydrates, proteins, and fats, are needed in larger quantities and provide energy and structural support.
- Micronutrients, such as vitamins and minerals, are required in smaller amounts and support vital functions like the immune system.
Organic and Inorganic Nutrients
- Organic nutrients include carbohydrates, proteins, fats, and vitamins, all containing carbon.
- Inorganic nutrients consist of minerals and water, which do not contain carbon.
Link Between Nutrition and Health
- Proper nutrition is crucial for good health and disease prevention.
- Poor dietary choices can lead to nutritional deficiencies and serious health issues.
Understanding Malnutrition
- Malnutrition encompasses undernutrition (insufficient nutrients) and overnutrition (excessive nutrients), both harmful to health.
- An unhealthy or imbalanced diet is a primary cause of malnutrition.
Health, Growth, and Maintenance
- Health is defined as overall physical, mental, and social well-being, not just the absence of disease.
- Growth involves physical, mental, and spiritual development throughout maturation.
- Maintenance refers to ongoing body processes that repair tissues and stabilize the internal environment for long-term health.
Energy Production
- The body converts nutrients into energy through chemical reactions necessary for bodily functions like movement and digestion.
- Nutrients serve as fuel for energy production, keeping the body active.
