Study Notes
- Nutrients are substances in food that aid in the body's growth, development, and maintenance of health
- The six basic nutrients are carbohydrates, proteins, fats, vitamins, minerals, and water
- Nutrition refers to the process of consuming and metabolizing nutrients
Carbohydrates
- Carbohydrates, including starches and sugars, provide the body's primary source of energy
- Simple carbohydrates break down rapidly, while complex carbohydrates take longer to digest
- The glycemic index classifies carbohydrates by how quickly and significantly they impact blood sugar levels
Fiber
- Fiber, an indigestible carbohydrate, facilitates the movement of food through the digestive system
- Soluble fiber partially dissolves in water, aiding in cholesterol reduction
- Insoluble fiber does not dissolve in water and helps prevent constipation
Proteins
- Proteins are essential nutrients that provide energy and support the building and maintenance of the body's cells and tissues
- The building blocks of proteins are amino acids
- Essential amino acids, which cannot be produced by the body, must be obtained through diet
- A complete protein supplies all essential amino acids
- An incomplete protein lacks one or more essential amino acids
Fats
- Fats are highly concentrated energy sources crucial for normal bodily functions
- Unsaturated fats are liquid at room temperature and considered healthy
- Saturated fats are solid at room temperature and considered unhealthy
- Trans fats are liquid fats that have been chemically altered to become solid
Cholesterol
- Cholesterol is a waxy, fat-like substance found in animal products and produced by the liver
- Low-density lipoproteins (LDL) are an unhealthy type of cholesterol that can accumulate in blood vessels
- High-density lipoproteins (HDL) are a healthy type of cholesterol that helps prevent heart disease
Vitamins
- Vitamins are organic substances that support energy release and maintain healthy cell and organ function
- Fat-soluble vitamins dissolve in fat and can be stored in the body
- Water-soluble vitamins dissolve in water and must be replenished regularly
Minerals
- Minerals are inorganic substances vital for various bodily functions
- Macrominerals are needed in amounts greater than 100 mg per day
- Trace minerals are needed only in small amounts
Water
- Water is a vital nutrient necessary for all bodily processes
