Course Objectives

  • Students will learn glycemic index, balanced diet, micronutrient deficiencies and the remedies, nutraceuticals and their importance, junk foods and their hazards. They will understand the need for specialized food for people with special needs - diabetes, pregnancy, inherited genetic disorders. Merits and demerits of vegetarian and non-vegetarian foods will be studied.

Learning Outcomes

  • Understand both fundamental and applied aspects of food science. Provides for fundamental understanding of food chemistry, and food microbiology. Gain insights about role of specific nutrients in maintaining health and identifying nutrient specific foods.
