Study Notes
Course Tips for Success
- Attend in-person class sessions; instructors will cover material not in notes. Pay attention to repeated information.
- Review online sections, including the news section and commentary in PowerPoint notes regularly.
- Focus on concepts and terms marked with asterisks (*).
- Practice applying learned concepts. Repetition is crucial.
- Don't cram; space out study sessions.
- Utilize textbook and office hours. Study with classmates.
Exam Preparation
- Review chapters before reviewing PowerPoint notes.
- Review PowerPoint slides thoroughly.
- Seek clarification on confusing topics from the instructor.
- Complete the study guide(s) as you review PowerPoint notes.
- Think actively about how the material applies to real life. Consider potential exam questions.
- Review supporting materials (videos, websites, and diagrams) posted on the course platform (D2L).
- Focus on bolded, underlined, asterisked, or repeated items in notes and study guides.
Why Study Nutrition?
- Two-thirds of U.S. deaths are linked to poor diet and/or inactivity.
- Obesity is the second leading cause of preventable death (smoking is #1).
- Nutrient intake (too much or too little) can lead to illness and death, even years later.
- Childhood/teen/young adult dietary choices impact later health, particularly affecting calcium/vitamin D and bone health.
- Peak bone mass occurs between ages 25-30; poor diet at younger ages can lead to osteoporosis.
Chapter Outline
- Nutrition overview
- Energy sources and uses
- The North American diet
- Nutritional health status
- Genetics and nutrition
- Scientific research and needs assessment
- Evaluating nutrition claims and products
Introduction to Chapter 1
- Diet is crucial for health and longevity.
- Poor diet is strongly associated with malnutrition, chronic disease, and nutrient deficiencies.
- Overweight/obesity, cardiovascular disease, type 2 diabetes, and some cancers are linked to diet.
- Plant-based diets with adequate fruits, vegetables, and whole grains can be protective against disease.
Causes of Death Related to Diet
- Diseases of the heart
- Cancer
- Cerebrovascular Disease
- Chronic obstructive lung disease
- Accidents
- Diabetes
- Influenza and pneumonia
- Alzheimer's disease
- Kidney disease
- Suicide
- All other causes
Nutrition Overview
- Nutrition: The study of food, nutrients, and their effects on health and disease.
- Nutrients: Substances essential for health; the body either cannot make them or makes them in insufficient quantities to maintain health. Essential nutrients must come from food.
- Not all foods provide all nutrients.
Nutrition Classes
- Macronutrients: Needed in large amounts (grams). Carbohydrates, lipids, protein and water.
- Micronutrients: Needed in small amounts (micrograms or milligrams). Vitamins and minerals.
Nutrients in the Human Diet
- Table includes numerous vitamins, minerals, and water.
Micronutrient Deficiencies
- Iron, iodine, and vitamin A are the most common worldwide.
- Deficiencies can affect wound healing, cognitive development, eyesight, and lead to fatigue, infection, premature death and birth defects.
Carbohydrates
- Composed of carbon, hydrogen, and oxygen (1:2:1 ratio). Aka "hydrated carbons".
- Primary energy source.
- Provide 4 kcal/gram.
- Divided into simple (sugars) and complex (starches). Simple can be monosaccharides (single) or disaccharides (double sugars). Complex carbs are polysaccharides (many monosaccharides joined together).
- Include cellulose, glycogen, and starch.
- Also include soluble and insoluble fiber.
Lipids
- Includes fats and oils (solid or liquid at room temperature).
- Composed of carbon, hydrogen, and oxygen.
- Provide 9 kcal/gram.
- Insoluble in water.
- Primary form is triglycerides (glycerol + 3 fatty acids).
- Saturated fatty acids are primarily from animals and are solid at room temp.
- Unsaturated fatty acids are primarily from plants and liquid at room temp.
- Trans fats are created by processing unsaturated fatty acids.
Proteins
- Composed of Carbon, Hydrogen, Oxygen, and Nitrogen.
- Provide 4 kcal/gram.
- 20 different amino acids; essential amino acids must be obtained through diet.
- Primary structural component in many body tissues.
Vitamins
- Enable chemical reactions in the body.
- Do not provide energy, but aid in energy release.
- 13 vitamins. Water-soluble and fat-soluble.
Minerals
- Simple, inorganic structures.
- Play many roles in the body (e.g., body system function, water balance, nutrient absorption).
- Divided into major minerals (needed in gram amounts daily) and trace minerals (needed in mg amounts daily).
Water
- Essential macronutrient for all body functions.
- Important as a solvent, lubricant, transport medium, and temperature regulation medium.
- The body needs a substantial amount of water.
Energy Sources and Uses
- Carbohydrates, lipids, proteins, and alcohol provide energy (calories)
- These are used to fuel bodily functions, build and repair tissues, and maintain body temperature.
Evaluating Nutrition Claims and Products
- Exercise caution and skepticism when reviewing nutrition claims.
- Supplements may be dangerous, so they are not evaluated as rigorously as drugs.
- The FDA may not have adequate information to identify potentially harmful products.
- Consult with healthcare providers for advice.
Nutritional Status
- Malnutrition: Nutrient intake either insufficient or excessive.
- Under nutrition: Nutrient stores are depleted, but person exhibits no symptoms.
- Clinical nutrition deficiency: Signs and symptoms of nutrient deficiency become apparent.
- Desirable ("optimal") nutrition: Enough nutrients to support functions and maintain body stores.
National Health Objectives
- Set societal health goals and objectives.
- Many targets directly related to nutrition (e.g., diet, nutrient intake, etc.).
Assessing Nutritional Status
- Anthropometric measurements (height, weight, etc)
- Biochemical tests (blood, urine, feces, etc)
- Medical history
- Dietary assessments (diet patterns, eating habits, etc)
- Environmental assessments (lifestyle, income, etc)
Nutrition and Genetics
- "Nutrigenomics": Focuses on the relationships between nutrition and gene expression.
- Dietary choices can affect gene expression and may be passed down to later generations.
- Family history plays a significant role in developing nutrition-related diseases (diabetes, cancer, osteoporosis, cardiovascular disease).
Basic Science-Based Inquiry/Methods
- Scientific method: A systematic approach to investigate natural phenomena.
- Observation, questioning, hypothesis formulation, experiments, data collection, analysis, conclusions, peer review.
- Control and experimental groups
- Correlation vs. causation
Additional Notes
- Correlation does not equal causation.
- Peer-reviewed studies are crucial for credibility.
- Look at the entire body of research and not just individual studies.
- Avoid letting personal biases sway your research conclusions. Look at all the evidence, and change your mind when warranted.
