Macronutrients in Nutrition

Macronutrients

• Carbohydrates:
  • Provide energy for the body
  • Found in grains, fruits, vegetables, and dairy products
  • Types: simple (sugars), complex (starches, fibers)
• Protein:
  • Build and repair tissues
  • Found in meat, poultry, fish, eggs, dairy, legumes, and nuts
  • Essential amino acids: cannot be produced by the body, must be consumed
• Fats:
  • Provide energy and support growth
  • Found in meat, dairy, oils, and fatty fish
  • Types: saturated, monounsaturated, polyunsaturated

Micronutrients

• Vitamins:
  • Fat-soluble: A, D, E, K
  • Water-soluble: B, C
  • Function: regulate metabolism, maintain healthy skin and bones, support immune system
• Minerals:
  • Macro-minerals: calcium, phosphorus, magnesium, potassium, sodium, chloride
  • Micro-minerals: iron, zinc, iodine, selenium, copper, manganese
  • Function: regulate bodily functions, support immune system, and maintain healthy bones and teeth

Diet and Health

• Recommended Daily Intake (RDI): varies by age, sex, and physical activity level
• Malnutrition: lack of essential nutrients, can lead to deficiencies and diseases
• Dietary Patterns:
  • Omnivore: consumes both plants and animals
  • Vegetarian: consumes plants and plant-based products
  • Vegan: consumes only plants and plant-based products
• Health Effects of Nutrition:
  • Obesity: excessive energy intake, leading to chronic diseases
  • Undernutrition: inadequate energy intake, leading to stunted growth and weakened immune system

Nutritional Assessment

• Anthropometric Measurements:
  • Height and weight
  • Body Mass Index (BMI)
  • Skinfold measurements
• Biochemical Measurements:
  • Blood tests: glucose, lipid profile, liver function tests
  • Urine tests: protein, sugar, and electrolyte levels
• ** Dietary Assessment**:
  • 24-hour dietary recall
  • Food frequency questionnaire
  • Dietary history

Macronutrients

• Carbohydrates provide energy for the body and are found in grains, fruits, vegetables, and dairy products, with two types: simple (sugars) and complex (starches, fibers).
• Protein builds and repairs tissues and is found in meat, poultry, fish, eggs, dairy, legumes, and nuts, with essential amino acids that cannot be produced by the body and must be consumed.
• Fats provide energy and support growth, found in meat, dairy, oils, and fatty fish, with three types: saturated, monounsaturated, and polyunsaturated.

Micronutrients

• Vitamins are fat-soluble (A, D, E, K) and water-soluble (B, C), regulating metabolism, maintaining healthy skin and bones, and supporting the immune system.
• Minerals are macro-minerals (calcium, phosphorus, magnesium, potassium, sodium, chloride) and micro-minerals (iron, zinc, iodine, selenium, copper, manganese), regulating bodily functions, supporting the immune system, and maintaining healthy bones and teeth.

Diet and Health

• Recommended Daily Intake (RDI) varies by age, sex, and physical activity level.
• Malnutrition is a lack of essential nutrients, leading to deficiencies and diseases.
• Dietary patterns include omnivore (consuming both plants and animals), vegetarian (consuming plants and plant-based products), and vegan (consuming only plants and plant-based products).
• Health effects of nutrition include obesity (excessive energy intake, leading to chronic diseases) and undernutrition (inadequate energy intake, leading to stunted growth and weakened immune system).

Nutritional Assessment

• Anthropometric measurements include height and weight, Body Mass Index (BMI), and skinfold measurements.
• Biochemical measurements include blood tests (glucose, lipid profile, liver function tests) and urine tests (protein, sugar, and electrolyte levels).
• Dietary assessment methods include 24-hour dietary recall, food frequency questionnaire, and dietary history.
