HORT*3310 Plants, Food and Health

course node page

This course will provide an in-depth understanding of plants grown for food, spices and grains as they relate to humans in terms of disease prevention and health. Plants and their familial characteristics, the metabolic pathways characteristic to specific food types, and their effects on human physiology will be discussed. The topic will be introduced in the context of world food habits, plants as food and hot spots of healthy populations and their food customs.

Learning outcomes:

By the end of this course, students should be able to:
  1. Have a broad knowledge about plants and their various parts used as food, and their utilization for food around the world.
  2. Know the evolutionary relationships between plant taxonomical grouping, and its relation to the chemistry of food products.
  3. Understand the implications of consuming a variety of foods with diverse dietary components and health.
  4. Develop a basic understanding of how the various dietary components influence human metabolism and help maintain health.
  5. Develop an understanding of fresh vs processed, and changes in dietary components that may occur during processing.
