Study Notes
Macronutrients
- Carbohydrates are the body's primary energy source, categorized as simple (sugars) or complex (starches and fibers).
- Simple carbs are quickly digested, causing a rapid rise in blood sugar.
- Complex carbs digest slower, providing sustained energy.
- Fiber, a complex carb, aids digestion and blood sugar regulation.
- Proteins build and repair tissues, produce enzymes and hormones, and support immunity.
- Proteins consist of amino acids; some are produced by the body, while others (essential amino acids) must come from food.
- Complete proteins contain all essential amino acids; incomplete proteins lack one or more.
- Fats (lipids) are vital for energy storage, hormone production, and cell membrane structure.
- Unsaturated fats (monounsaturated and polyunsaturated) are generally healthier.
- Saturated and trans fats are often associated with negative health outcomes.
Micronutrients
- Vitamins and minerals are essential for bodily functions like metabolism, growth, and development.
- Vitamins are organic compounds needed in small amounts for metabolic processes.
- Minerals are inorganic substances crucial for fluid balance, nerve function, and bone health.
Dietary Guidelines
- A balanced diet is key for health and well-being.
- A balanced diet includes fruits, vegetables, whole grains, lean proteins, and healthy fats.
- Limit processed foods, sugary drinks, and excessive saturated/unhealthy fats.
- Portion control is important for weight management.
Energy Balance
- Energy balance is the relationship between calorie intake and expenditure.
- Excess calorie intake leads to weight gain.
- Excess calorie expenditure leads to weight loss.
Nutritional Needs Across the Life Cycle
- Nutritional needs vary by age, activity level, and health status.
- Infants, children, and adolescents need nutrients for growth and development.
- Adults' needs vary based on activity and health conditions.
- Older adults may have altered absorption and metabolism needs.
- Pregnancy and breastfeeding require increased nutrient intake.
Dietary Considerations
- Food allergies/intolerances affect dietary choices, requiring careful planning.
- Food sensitivities can cause various symptoms.
- Vegetarian/vegan diets require careful meal planning to meet nutritional needs.
- Understanding food labels and nutritional information is crucial for informed choices.
Hydration
- Adequate water intake is essential for bodily functions.
- Water regulates body temperature, transports nutrients, and removes waste.
- Insufficient water intake leads to dehydration, impacting bodily functions.
Dietary Supplements
- Supplements can fill nutritional gaps or enhance health aspects.
- Consult a healthcare professional before using supplements.
- Supplements are intended to supplement, not replace, a healthy diet.
