Student Learning Outcomes

  • Upon successful completion of the course, students will be able to utilize the dietary Guidelines for Americans to plan a diet for both healthy individuals as well as individuals at increased risk for chronic illnesses such as heart disease and type 2 diabetes.
  • Upon successful completion of the course, students will be able to utilize dietary analysis software to analyze current dietary intake and subsequently make suggestions for appropriate dietary modifications, and explain the rationale for these recommendations.
  • Upon successful completion of the course, students will be able to interpret food labels, explain the rationale for the information, and teach a potential patient how to use the labels to make informed dietary choices.

Description

Introduction to the medical aspects of nutrition, intended for students wishing to pursue a career in health care. Biological function and chemical classification of nutrients. Nutritional needs throughout the lifespan. Effects of nutritional deficiencies and excesses. Recommended nutrient intakes and the role of diet in the development of chronic disease.

Course Objectives

The student will be able to:
A. explain the scientific basis for and the uses of various food and nutrient guides across the lifespan
B. outline basic steps used in evaluation of nutritional status and discuss limitations of the various techniques
C. describe the chemical structure and biological functions of macronutrients and recall recommendations and major food sources for each
D. discuss the major steps of macronutrient metabolism
E. recall the factors influencing energy balance and appraise the role that they play in the management of weight control
F. describe the major roles of vitamins and minerals and relate the effects of deficiencies and excesses to their metabolic functions
G. assess the nutritional adequacy of a diet of a healthy person and propose specific changes that will reduce the possibility of chronic disease and malnutrition
H. describe appropriate food safety practices and mechanisms for prevention of food-borne illness
I. critically evaluate resources for current nutrition information
J. discuss the role of the human gut microbiome in maintaining homeostasis and in moderating risk for chronic diseases
