Study Notes
Nutrients and Energy
- Carbohydrates, fats, and proteins are the three nutrient classes that provide energy to the body.
- Carbohydrates are the primary energy source for bodily functions.
- Fats serve multiple roles: provide energy, form cell membranes, maintain body temperature, and protect nerves.
- Proteins mainly help with tissue growth and repair, but can also supply energy.
Metabolism
- Metabolism refers to the chemical processes that convert food into usable energy.
- It enables the body to extract nutrients from food for daily activities.
Calories
- Calories measure energy released from nutrients during breakdown.
- Caloric intake varies based on age, physical activity level, gender, and body needs.
Carbohydrates
- Two main types: simple carbohydrates (sugars) and complex carbohydrates (starches and fiber).
- Fiber, a complex carbohydrate, is found in plants and supports digestive health.
Fats
- Fats are categorized into saturated, unsaturated, and trans fats.
- Cholesterol is a waxy substance present only in animal products.
Proteins and Amino Acids
- Proteins consist of long chains of amino acids, which are the building blocks of proteins.
Vitamins and Minerals
- Vitamins are organic compounds necessary for numerous bodily functions and are classified as fat-soluble (A, D, E, K) or water-soluble (B1, B2, B3, B6, B12, Pantothenic acid, Folate, Biotin, C).
- Antioxidants are vitamins that protect cells from damage associated with aging and cancer.
- Minerals are inorganic nutrients necessary in small amounts, primarily derived from rocks and soil.
- Significant minerals include calcium, sodium, potassium, magnesium, phosphorus, chlorine, and sulfur.
Health Implications
- A lack of calcium can lead to osteoporosis, a condition characterized by weak and brittle bones.
Dietary Guidelines
- Key recommendations include making smart food choices, balancing food intake with physical activity, maximizing nutrition from calories, and practicing safe food handling.
MyPyramid Plan
- The MyPyramid plan categorizes foods into groups and suggests daily intake amounts for a balanced diet.
- The pyramid features six colored bands representing food groups, with the width of each band indicating the proportion of food recommended from that group.
- Stair steps in the pyramid symbolize the importance of physical activity for maintaining overall health.
