    Study Notes

    Course Information

    • Course name: NATS1560: Understanding Food
    • Course instructor: Angela Cope
    • Course contact email: [email protected]

    Learning Objectives

    • Define science and technology and explain how they relate to food
    • Describe the main characteristics of modern science
    • Define nutrition science and food science & technology
    • Differentiate between foods and nutrients
    • Preview human nutritional needs

    Understanding Food

    • Modern science is used to understand food
    • Food production and processing rely heavily on industrial technology
    • Nutrition science studies how food provides nourishment
    • Food science/technology research food properties to create/improve food products and preservation methods
    • Other fields like agricultural and environmental science also study food production systems

    Science and Technology

    • Science is the systematic study of the natural world, producing knowledge.
    • Technology manipulates nature for practical purposes, creating artifacts and systems.
    • Science and technology are social processes with defined knowledge, training, organization, and interactions.
    • They are closely linked, often referred to as "technoscience"
    • Technoscience has significant consequences (good and bad, intended and unintended)
    • Often creates technical, social, political, and ethical controversies

    Science and Technology Meet Food

    • Nutrition science and food technoscience share modern science characteristics
    • Materialism: living organisms are physical systems governed by laws of matter and energy.
    • Reductionism: complex phenomena are reducible to interactions of simple components (atoms, molecules)
    • Experimentalism: scientific explanations are derived and tested through experiments.
    • Food technoscience faces many technical, social, political, and ethical issues.

    Importance of Understanding Food

    • Food, nutrient requirements, and metabolism are complex.
    • Food is integrated into culture.
    • Nutrition science, while reductionist and materialist, is incomplete without considering the whole political, economic, cultural, and social context when studying food.

    Foods and Nutrients

    • Foods are substances we eat.
    • Nutrients are the chemically identified parts of food that provide nourishment
    • Most foods are composed of numerous nutrients, not simple combinations.
    • Nutrition aims to understand nutrients required for a healthy diet, including specific quantities and functions.

    Human Nutrients

    • Water is essential
    • Carbohydrates (simple and complex, digestible and indigestible)
    • Fats (saturated, unsaturated)
    • Proteins (many different types from amino acids)
    • Minerals (major and trace)
    • Vitamins (water and fat soluble)
    • Phytochemicals (still under study)

    Review Questions

    • What is an example of a food?
    • What is an example of a nutrient?
    • How are nutrients related to foods?
    • What are the nutrients our bodies use for energy?
