Macronutrients: Carbohydrates, Protein, and Fat

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 body tissues
  • Found in animal products, legumes, nuts, and seeds
  • Essential amino acids: cannot be produced by the body, must be consumed
• Fat:
  • Provide energy, absorb vitamins, and maintain healthy skin and hair
  • Found in animal products, nuts, seeds, and oils
  • Types: saturated, unsaturated, trans

Micronutrients

• Vitamins:
  • Essential for energy production, immune function, and growth
  • Found in fruits, vegetables, whole grains, and fortified foods
  • Types: fat-soluble (A, D, E, K), water-soluble (B, C)
• Minerals:
  • Crucial for various bodily functions, such as nerve function and bone health
  • Found in fruits, vegetables, whole grains, and fortified foods
  • Types: macrominerals (calcium, phosphorus, potassium), microminerals (iron, zinc, iodine)

Nutrition Recommendations

• Dietary Reference Intake (DRI):
  • Estimating daily nutrient intake for optimal health
  • Includes Recommended Dietary Allowance (RDA), Adequate Intake (AI), and Tolerable Upper Intake Level (UL)
• Healthy Eating Patterns:
  • Emphasize whole, minimally processed foods
  • Include a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats
  • Limit added sugars, saturated fats, and refined carbohydrates

Nutrition-Related Health Issues

• Malnutrition:
  • Inadequate or excessive nutrient intake
  • Can lead to impaired growth, weakened immune system, and increased disease risk
• Deficiency Diseases:
  • Caused by inadequate intake of specific nutrients (e.g., scurvy from vitamin C deficiency, anemia from iron deficiency)
• Chronic Diseases:
  • Linked to poor nutrition and lifestyle choices (e.g., obesity, diabetes, cardiovascular disease)

• The Dietary Reference Intake (DRI) is used to estimate daily nutrient intake for optimal health and includes the Recommended Dietary Allowance (RDA), Adequate Intake (AI), and Tolerable Upper Intake Level (UL).
• Healthy Eating Patterns emphasize whole, minimally processed foods, including a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats, while limiting added sugars, saturated fats, and refined carbohydrates.

Nutrition-Related Health Issues

• Malnutrition occurs when there is inadequate or excessive nutrient intake, leading to impaired growth, weakened immune system, and increased disease risk.
• Deficiency Diseases are caused by inadequate intake of specific nutrients, such as scurvy from vitamin C deficiency or anemia from iron deficiency.
• Chronic Diseases, such as obesity, diabetes, and cardiovascular disease, are linked to poor nutrition and lifestyle choices.
