The course will focus on the pillars of the science of nutrition and the essential components of healthy eating. The role of macronutrients (fat, protein, carbohydrates) and micronutrients (the major classes of fats and minerals) on overall energy intake and their role in our health will be examined. Specific global concerns relevant to nutrition will be explored; for example, the discussion of macronutrients will include a focus on undernutrition and obesity at both ends of the caloric intake spectrum and how the global community struggles with it.
