Nutrition 331: Nutrition for Health surveys the basic principles of human nutrition and the relationships between nutrition and chronic diseases. There is now a large body of evidence demonstrating that diet has a major impact on health. In this course, we examine all aspects of this subject.

For a student who plans to take only one nutrition course at Athabasca University, NUTR 331 is the best choice. It is also the best nutrition course for students with limited science background. Students wanting to study nutrition in more detail should take NUTR 330 followed by NUTR 405.
