    Study Notes

    Food in Daily Life

    • Food provides nourishment and fuel.
    • Appetite is the desire for food, a conditioned response and can be triggered by the senses.
    • Unlike hunger, appetite can be satisfied.
    • Satiety is the feeling of fullness. Different foods have varying abilities to create satiety.
    • Foods with a low glycemic index, high in protein, or high in carbohydrates help reach satiety.
    • Hunger is the need for food, the result of chemical changes when glucose levels are low.

    Macronutrient Digestion

    • Main nutrients in food are carbohydrates, proteins, and fats.
    • Carbohydrates are sugars, starches, and cellulose (plant matter).
    • Monosaccharides are simple sugars (e.g., glucose).
    • Disaccharides are formed by joining two monosaccharides (e.g., sucrose, lactose).
    • Polysaccharides are many monosaccharides joined (e.g., starch).
    • Proteins are made of amino acids and chains. They build, maintain, and repair cells, and produce energy.
    • Fats are stored for long-term energy.
      • Saturated fats are from animal products (butter, sausages, bacon).
      • Unsaturated fats are from plant sources (fish oil, avocados).
      • Trans fats are artificially created (pies, pastries, butter).

    Digestion Process

    • Digestion breaks down macronutrients into smaller molecules for absorption.
    • Mechanical digestion breaks down food into smaller pieces (e.g., chewing, stomach contractions).
    • Chemical digestion uses enzymes and digestive juices (e.g., salivary amylase, pepsin, pancreatic lipase).

    Gastrointestinal Tract and Accessory Organs

    • Main organs: mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.
    • Accessory organs: tongue, salivary glands, liver, pancreas, and gallbladder.
    • Salivary amylase starts digestion in the mouth.
    • Peristalsis moves food through the esophagus.
    • The stomach mixes food with gastric juices (killing bacteria, and breaking down proteins and fats).
    • The liver produces bile; the pancreas releases enzymes into the small intestine.
    • The small intestine digests and absorbs macronutrients through villi.
    • The large intestine absorbs water and remaining nutrients; waste is eliminated through the anus.
    • Carbohydrates are absorbed as simple sugars.
    • Proteins are absorbed as amino acids.
    • Fats are absorbed as fatty acids and glycerol.

    Gut Microbiota and Health

    • Microbiota are microorganisms living in or on humans (bacteria, fungi, and viruses).
    • The large intestine contains more gut microbiota than the small.
    • Prebiotics are non-digestible carbohydrates.
    • Microbiota consume prebiotics and produce short-chain fatty acids for cellular energy and reduce inflammation.
    • Disruptions to the gut microbiota can negatively impact mental wellbeing.
    • Gut microbiota can influence hormone secretion (serotonin, dopamine).

    Food Choices

    • Diets high in processed foods, sugars, red meat, fast food negatively impact gut bacteria.
    • Plant-based foods, prebiotics, probiotics, and resistant starch improve gut health.
    • Trends and fads affect food purchasing.
    • Age, sex, pregnancy, lactation, and activity influence dietary requirements.
      • Pregnant women need specific nutrients to prevent neural tube defects and support the baby's growth.
      • Lactating women need more energy and nutrients to produce milk.

    Food Allergies and Intolerances

    • Allergies are immune system reactions to foods.
    • Symptoms can range from mild to life-threatening (anaphylaxis).
    • Food intolerances are chemical reactions (not an immune response).
    • Reactions can be delayed and vary widely.
    • Common causes include dairy, eggs, food additives, or flavour enhancers, or potentially chocolate, garlic, and fruits.
    • Celiac disease is caused by the intolerance to gluten.
    • Lactose intolerance affects the digestion of lactose.
    • FODMAP intolerance causes digestive discomfort.

    Food Systems and the Environment

    • Food security is when all people have access to sufficient, safe, and nutritious food.
    • Food sovereignty is the ability to choose what you want to eat, where it comes from, and how it is grown.
    • Food citizenship is considering the impact of food choices on both personal health and the environment.
    • Climate change can impact food production through temperature changes or weather patterns.
    • Consumption and manufacturing impact the environment.
    • Packaging, transportation, and disposal of food waste can cause harm.
    • Environmental considerations for farming include fertilisers, pesticides, water, crop and animal choices, biosecurity, biodiversity, and climate change.

    Food, Mental Health, and Wellbeing

    • Food can impact mental health by influencing dopamine and serotonin levels.
    • A diet high in salt, fat and sugar can reduce these hormone levels.
    • Antioxidants, Omega 3 fats, prebiotics, probiotics are linked to improved mental wellbeing.
    • Excessive amounts of fats, salt, and sugar can decrease mental wellbeing and cause mood swings.

    Policy and Regulation

    • Food labeling standards determine details that must be on food labels.
    • Health claims for food have to meet specific standards.
    • Regulations for food advertisements and marketing.

    Food Information and Accuracy

    • Credible sources of food information are essential to making responsible food decisions.
    • Understanding the origin, and production process of food is important.
    • Food labels must contain nutritional information.
    • Food advertisements and marketing contain claims that must have evidence and meet standards.
