Study Notes
The Basics of Nutrition
-
Nutrition is crucial for health, encompassing the study of nutrients and their roles in the body.
-
Six classes of nutrients are essential for bodily functions:
- Carbohydrates: Primary source of energy.
- Lipids: Also provide energy and support cellular structure.
- Proteins: Vital for structure, function, and regulation of the body.
- Vitamins: Regulate various bodily processes and help prevent diseases.
- Minerals: Assist in bodily functions including bone health and metabolism.
- Water: Essential for maintaining fluid balance and overall bodily functions.
-
Poor dietary choices lead to chronic diseases like heart disease, cancer, and type 2 diabetes.
-
Regular exercise and a balanced diet help mitigate health risks.
Essential Nutrients
- Essential nutrients must be obtained from food, as the body cannot produce them sufficiently.
- Examples of essential nutrients include certain vitamins (like Vitamin C) and minerals (like calcium).
- Phytochemicals: Non-nutrient plant compounds that may provide health benefits, such as antioxidants.
Food Energy
- Energy is quantified in kilocalories (Calories).
- Macronutrients (carbohydrates, fats, proteins) provide energy, whereas micronutrients (vitamins, minerals) do not.
Balanced Diet
- A variety of foods from different groups is necessary for nutritional adequacy; no single food provides all necessary nutrients.
