Study Notes
About Registered Dietitians
- Registered Dietitian (RD) requires a Bachelor of Science in nutrition from an accredited university.
- Must complete 1200+ hours of supervised internship through an accredited program.
- RD credential maintained through 75 hours of continuing education every five years.
- Nutritionist (RDN) has no specific education requirements and anyone can claim this title.
Understanding Nutrition
- Nutrition is the science studying the interaction between nutrients and body functions.
- Focuses on health, growth, and athletic performance enhancement.
Nutrients and Their Functions
- Nutrients are substances needed for energy, growth, and development.
- Three main functions of nutrients: provide energy, repair tissues, regulate body processes.
- Specific amounts are needed, with both deficiency and excess potentially harmful.
Metabolism Insights
- Metabolism encompasses all biochemical reactions in the body, like muscle contraction and neuron firing.
- Faster metabolism requires more calories, especially during exercise.
- Metabolic rate is the speed of metabolism, with several categories:
- Basal Metabolic Rate (BMR): energy needed to sustain basic life functions.
- Resting Metabolic Rate (RMR): energy needed while at rest.
- Thermic Effect of Food (TEF): energy required to digest food.
- Thermic Effect of Exercise (TEE): additional calories burned during physical activities.
- Non-Exercise Activity Thermogenesis (NEAT): calories burned through non-exercise activities.
Factors Affecting Metabolism
- Age contributes to slower metabolic rates, leading to potential weight gain.
- Muscle mass significantly influences calorie burning; greater muscle mass means higher calorie requirements.
- Environmental temperature requires the body to burn more calories to maintain temperature.
- Hormonal disorders can adversely affect metabolic rates.
Misconceptions About Obesity and Metabolism
- Research indicates individuals with obesity often have higher metabolic and resting metabolic rates.
- Greater muscle mass due to carrying extra weight contributes to increased metabolic rates.
- Individuals previously obese tend to have slightly lower metabolic rates compared to those who have never been obese.
Nutrient Classification
- Essential nutrients cannot be synthesized in sufficient amounts by the body and must come from diet.
- Non-essential nutrients can be adequately produced by the body, although their intake can be beneficial.
- Classification includes:
- Macronutrients: carbohydrates, proteins, fats.
- Micronutrients: vitamins, minerals, water.
Nutritional Terms and Definitions
- Enriched foods have nutrients added back after processing, e.g., white bread enriched with B vitamins.
- Fortified foods have nutrients added that were not originally present, e.g., milk fortified with vitamin D.
- Dietary supplements include vitamins, minerals, and herbal ingredients, intended as additions to the diet.
- Phytochemicals are plant compounds that benefit health but are not classified as essential nutrients.
Understanding Calories
- A calorie is a unit of energy, defined as the energy needed to raise the temperature of 1 kg of water by 1°C.
- Macronutrient calorie contributions:
- Carbohydrates and proteins: 4 calories per gram.
- Fats: 9 calories per gram.
- Water: 0 calories.
- Alcohol: 7 calories per gram.
Macronutrient Distribution
- Acceptable Macronutrient Distribution Range (AMDR) for daily calorie intake:
- Carbohydrates: 45-65%
- Fats: 20-35%
- Proteins: 10-35%
- Intakes relate to reduced chronic disease risk.
Nutrient Density
- Nutrient density assesses the nutrient content relative to calorie content.
- High nutrient density is preferred, emphasizing foods rich in vitamins and minerals with fewer calories, like fruits over candy.
