  • Course Learning Objectives

    Upon successfully completing this course, students will be able to:

    • List the major macro and micronutrients relevant to human health
    • Discuss the scientific rationale for defining nutritional requirements in healthy individuals and populations, with reference to specific conditions such as pregnancy, lactation, and older age
    • Present current evidence for the role of key nutrients in the prevention of chronic diseases
    • Discuss major nutrition-related diseases in a global context
  • Course Description
    Provides an integrated overview of the physiological requirements and functions of protein, energy, and the major vitamins and minerals that are determinants of health and disease. Topics include dietary sources, intake levels, and biological determinants of nutrient requirements; assessment of nutrient status in individuals and populations; the role of nutrition in growth and health through the life cycle; the rationale for the development of dietary guidelines and of nutrition policies in different countries; and the role of diet on the development of chronic diseases, such as cardiovascular disease, cancer, diabetes, etc.

    Additional Faculty Notes:

    The course covers three broad areas: 1) the biological determinants and estimation of nutrient needs of individuals and populations, including assessment of adequacy of diets for individuals and groups; 2)  overview of selected nutrients: macronutrients (protein, carbohydrates, fat) and selected micronutrients (vitamins A, E, folate, B12, iron, calcium, iodine): dietary sources, physiological functions, deficiency and excess, assessment of adequacy, health effects; 3) Diet and disease: obesity and chronic diseases, protein-energy malnutrition.  

  • Methods of Assessment
    Student evaluation based on a take-home exercise and final exam.

    Additional Faculty Notes:

    The grades for this course will be based on a mid-term and a final exam.  Both exams will occur in class and will consist of multiple choice questions and short (1 page max) essay questions.  The mid-term exam will have 15 multiple choice questions (45%) and the final exam will have 15 multiple choice questions and two essays (55%). 

    There will be a review session prior to the final exam.
