Study Notes

Kilocalories and Nutrition Basics

  • A kilocalorie measures the amount of heat energy.
  • Overnutrition is a greater risk than undernutrition in the United States.
  • Dietary supplements are not rigorously regulated by the FDA; manufacturers are not required to prove safety before selling.
  • Water-soluble vitamins are excreted more readily compared to fat-soluble vitamins.

Epidemiology and Nutrition Definitions

  • Epidemiology is the study of disease distribution in human populations.
  • Nutrition encompasses the science of food and nutrients, including their action and balance related to health.

Dietary Factors and Nutritional Sources

  • Food choices in North America are largely influenced by appetite.
  • Phytochemicals are plant substances that offer health benefits.
  • Triglycerides are the major form of lipids in foods.
  • Nitrogen is an element found in proteins but absent in carbohydrates.

Trusted Sources and Energy Yielding Nutrients

  • Registered dietitians are reliable sources of accurate nutrition information.
  • Energy-yielding nutrients include carbohydrates, proteins, and fats.
  • Carbohydrates can be sourced from grains, vegetables, and fruits.

Nutrient Density and Daily Values

  • A nutritious meal is exemplified by a combination of fruits, vegetables, and lean proteins.
  • The Acceptable Macronutrient Distribution Range (AMDR) helps prevent chronic diseases and ensures essential nutrient intake.
  • The Estimated Average Requirements (EAR) reflects average daily nutrient needs.

Food Labeling and Dietary Reference Intakes

  • The ingredients listed on food labels represent quantities from most to least.
  • Dietary Reference Intakes (DRIs) apply to populations in Canada and the U.S., categorized by age.
  • Tolerable Upper Intake Levels (ULs) indicate maximum nutrient intake levels unlikely to cause harm.

Food Security and Nutrient Preservation

  • Food insecurity affects physical and mental health, especially in vulnerable populations such as children and women.
  • The U.S. government provides food assistance through programs like WIC and SNAP.
  • Nutrient content is affected by farming conditions, ripeness, and cooking methods.

Digestion and Macronutrient Metabolism

  • Most digestion occurs in the small intestine, where bicarbonate ions neutralize stomach acid.
  • Protein digestion begins in the mouth with amylase, and dietary fiber promotes bowel health.
  • Bile, produced in the liver and stored in the gallbladder, aids in fat digestion.

Carbohydrates and Sugars

  • The human brain primarily uses glucose as fuel.
  • The Adequate Intake for dietary fiber is set at 14 g per 1000 kcal.
  • Important disaccharides include maltose, sucrose, and lactose.

Alcohol and Metabolism

  • Moderate drinking is defined as up to one drink per day for women and two for men.
  • Binge drinking for men is defined as five or more drinks in one occasion.
  • Alcohol absorption occurs in both the stomach and small intestine, with the liver being the primary site for metabolism.

Nutritional Deficiencies and Impacts

  • Excessive alcohol intake can lead to deficiencies in several vitamins, notably thiamin and niacin.
  • The relationship between protein intake and energy percentage indicates health status; the recommended protein intake is 10-35% of total energy.

Essential Nutrients and Dietary Guidelines

  • Essential fatty acids include alpha-linolenic and linoleic acids.
  • Legumes are an excellent plant-based protein source.
  • Dietary guidelines recommend limiting saturated fat and total fat intake as a part of a healthy diet.

Food Safety and Quality

  • The Environmental Protection Agency regulates public water supply safety.
  • Perishable foods should be stored out of the temperature danger zone (41°F to 135°F).
  • Foods labeled as fortified contain added nutrients beyond what is typically found.

These notes condense critical concepts in nutrition while providing context around each fact for enhanced understanding and retention.
