Study Notes
Balanced Diet for Optimal Health
- Focus on a balanced diet rich in fruits, vegetables, whole grains, and lean protein.
- Portion control is vital; avoid skipping meals.
- Adequate protein intake is crucial for muscle growth and repair.
- Limit processed foods, sugary drinks, and unhealthy fats (like saturated fat).
Basic Nutrients and Their Roles
- Water: Essential for all bodily functions. Every organ relies on water to function correctly.
- Vitamins: Support overall health and prevent disease. Crucial vitamins include A, B6, C, and D (among others). There are 13 types.
- Proteins: Building blocks of the body; account for 16% of an adult's mass. Essential even during weight loss.
- Fats: Aid in nutrient absorption and cell development. Excessive amounts are detrimental.
-
Minerals: Essential for diverse bodily functions.
- Calcium: Strengthens bones.
- Iron: Crucial for red blood cells.
- Zinc: Promotes healing.
- Carbohydrates: Fuel for the brain and nervous system. Provides energy.
Macronutrient Breakdown (Digestion)
-
Mouth: Mechanical digestion through chewing. Saliva's enzymatic activity breaks down carbohydrates.
-
Esophagus: Transports food to the stomach.
-
Stomach: Gastric juices begin breaking food down into smaller components.
-
Small Intestine: Primary site of nutrient absorption.
- Pancreatic enzymes break down fats, proteins, and carbohydrates.
- Bile from the liver aids in fat digestion.
- Nutrient breakdown results in glucose (from carbs), fatty acids (from fats), and amino acids (from proteins).
-
Bloodstream: Nutrients absorbed through the intestinal wall are carried to cells.
-
Glucose Utilization:
- Immediate Energy – Used by cells as fuel.
- Glycogen Storage – Saved in the liver and muscles for later use.
- Excess Glucose – Converted to fat (lipogenesis).
-
Fat Storage (Adipose Tissue):
- Triglycerides are synthesized and stored in fat cells.
- Low energy demand; excess energy is stored as triglycerides.
- Excessive storage leads to fat accumulation, increased body weight, and health complications.
Additional Dietary Guidance for Teens
- Fruits and vegetables: Essential daily components of a teen's diet.
- Calcium: 1300mg daily intake is crucial.
- Protein: Maintain muscle building and organ development.
- Whole grains: Provide sustained energy.
- Iron-rich foods: Important for health.
- Limit fat: Reduce intake of unhealthy fats.
