Lecturer's view

“Our Diet and Health short course is where students start to build their understanding of how nutrients work in the body, how they affect health and disease, and how wider factors — like lifestyle and environment — shape what people eat. I think this course is such an important starting point because it gives you a strong, research-based framework for thinking about the relationship between nutrition, health, and disease.”

Good to know
You can take the Diet and Health short course either for academic credit (Credit Bearing option) or simply for personal interest (non-Credit Bearing). It’s a great way to explore the fundamentals of nutrition without committing to a full programme. You’ll gain a broad, holistic view of how food choices, production, and dietary guidance affect health — plus develop practical skills to critically assess nutritional information.
