Nutritional Basics
- Inadequate Nutrient Intake: Can result in low energy, chronic diseases, and serious health issues.
-
Nutrient Types:
- Macronutrients: Needed in larger amounts; includes carbohydrates, proteins, and fats.
- Micronutrients: Needed in smaller amounts; includes vitamins and minerals.
Macronutrients
-
Carbohydrates:
- Comprises sugars, starches, and fibers; found in fruits, grains, and vegetables.
- Primary energy source, easily broken down into glucose for muscle and brain use.
-
Proteins:
- Made of amino acids; functions as hormones, enzymes, and antibodies.
- Essential for bodily structures such as connective tissues, skin, hair, and muscle fibers.
-
Fats:
- Unsaturated fats aid metabolism, improve blood flow, and promote cell growth.
- Important for the absorption of fat-soluble vitamins A, D, E, and K.
Micronutrients
-
Vitamins:
- Crucial for energy release from food, protein synthesis, and cell multiplication.
- Play roles in collagen production, wound healing, vision protection, and disease defense.
-
Minerals:
- Maintain water balance and stabilize protein structures.
- Essential for oxygen transport and sensory functions like taste and smell.
