About this course

Nutrition is defined as the mechanical and physiological process by which nutrients are absorbed and assimilated by living organisms for sustenance.

In this course, the student will be introduced to basic concepts of calories and energy expenditure; nutrition in special populations such as pregnant women and the elderly; and malnutrition. For optimal comprehension, students should be familiar with the basics of biomolecules and their metabolic pathways.

Nutritionists are experts in the study of nutrition. They play a crucial role in the healthcare team by providing individualized assessments of caloric needs and required intake, and by providing suggestions on the most appropriate formulations that can supply these needs.

Importance of the field of nutrition for the medical career and in general: A basic understanding of nutrition is helpful in both inpatient and outpatient care and can be used to make sound lifestyle recommendations or ensure the recommended caloric intake in chronically ill individuals who are in the ICU.
