Study Notes
Nutrition Overview
- Nutrition is the study of nutrients and their utilization by the body.
- Nutrients are substances essential for growth and maintenance.
- A variety of foods is necessary since no single food contains all nutrients.
Six Essential Nutrients
- The six essential nutrients include carbohydrates, fats, proteins, vitamins, and minerals.
Carbohydrates
- Primary energy source for the body, classified into simple and complex types.
- Simple carbohydrates: Fast energy from sugars (e.g., candy, soda); leads to a "crash and burn" effect.
- Complex carbohydrates: Provide long-term energy from foods like pasta, bread, and starchy vegetables (e.g., peas, potatoes).
- Fiber: A type of carbohydrate from plant sources (fruits, vegetables, whole grains); aids digestion and helps eliminate waste.
Fats
- Serve to store energy, insulate the body, and protect organs, containing twice as many calories as carbohydrates.
- Types of fats:
- Saturated fats: Solid at room temperature.
- Unsaturated fats: Liquid at room temperature, referred to as oils.
- Trans fats and cholesterol also fall under the fat category.
Proteins
- Building blocks for body growth and repair, essential for skin, hair, blood, muscles, and organs.
- Composed of amino acids.
- Protein sources:
- Plant-based (incomplete proteins): Beans, soy, lentils.
- Animal-based (complete proteins): Beef, pork, fish, eggs, cheese, poultry.
Vitamins
- Needed in small amounts to regulate body functions, utilize energy, and combat infections.
- Examples include vitamins A, B, C, D, E, and K.
- Sources primarily include fruits, vegetables, and dairy.
- Some vitamins are fat-soluble (stored in body fats), while others are water-soluble (stored in bodily fluids).
Minerals
- Essential for controlling chemical reactions in the body.
- Important for maintaining strong bones, healthy teeth, and proper blood function.
