Study Notes
Nutrition and Health
- Good nutritional status includes alertness, good nature, well-developed body, normal weight, firm muscles, healthy skin, and clear eyes.
- Indicators of general good health: stamina for work, regular meal times, consistent sleep, normal elimination, and disease resistance.
- Poor nutritional status manifests as irritability, poorly developed body, abnormal body weight, flabby muscles, pale skin, and poor appetite.
- Poor nutritional quality can stem from bad food choices and irregular schedules.
Malnutrition
- Defined as an undesirable nutritional state leading to health issues due to imbalances in nutrient intake.
- Includes undernutrition (insufficient essential nutrients) and overnutrition (excessive nutrient intake).
- Underlying causes of malnutrition can be primary (lack of nutrients) or secondary (metabolic errors, nutrient interactions).
Food and Diet
- Diet encompasses all foods and drinks consumed daily, including therapeutic diets modified for health needs.
- Nutritional care involves planning and preparing meals using nutritional knowledge, tailored to individual needs.
Functions of Food
- Physiological functions: provide energy for bodily processes, support growth and maintenance of tissues, regulate internal body activities (e.g., temperature, muscle contraction), and enhance disease resistance.
- Psychological functions: food meets emotional needs such as security, love, and attention.
Nutrients and Their Functions
- Foods contain various nutrients classified by chemical composition, including carbohydrates, proteins, fats, vitamins, minerals, and water.
- Carbohydrates provide immediate energy and are stored as glycogen or fat.
- Fats serve as concentrated energy sources, carriers of fat-soluble vitamins, and provide essential fatty acids.
- Proteins are crucial for building and repairing tissues, and synthesizing regulatory substances like hormones and enzymes.
Nutritional Composition of Common Foods
- Rice/Wheat: Offer energy and some vitamins; protein content varies.
- Fruits and vegetables: Provide essential vitamins (e.g., Vitamin C), fiber, and hydration.
- Milk, eggs, and meat: Rich in proteins and essential nutrients.
Food Exchange Lists
- Developed to assist individuals, especially diabetics, in selecting appropriate foods based on caloric value.
- Indian organizations created specific food exchange lists based on regional food availability and meal patterns.
- Food exchanges represent similar calorie and macronutrient values to aid in diet planning.
Nutrient Density
- Refers to the nutrient content relative to the calorie content of foods.
- Important for dietary selections, especially in special populations (children, pregnant women, and patients).
- Example comparison shows dal has higher protein density than milk or bread in isocaloric portions.
Key Concepts
- Nutrition: The process by which organisms utilize food to support life.
- Nutritional Care: Strategies employed to improve health through diet.
- Optimum Nutrition: Achieving balanced intake of nutrients to support overall health.
- Undernutrition: Inadequate intake of nutrients leading to health issues.
Important Quotes
- “Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” – WHO
