While we’ve never known more about diet and health, there remain many unanswered questions in nutrition science. However, there are often disagreements on how best to answer these questions, particularly in relation to informing practical diet advice that meaningfully improves health.
Prof. Norman Temple is one academic who has written on a number of these issues. One issue he highlights is the large discrepency in the practical value we have attained from cohort studies and RCTs, relative to mechanistic research. Another is the limitations of RCTs for nutrition-specific research questions.
In this episode, Prof. Temple discusses these issues, as well as what strategies can actually improve population diet, and thus health.
Prof. Norman Temple
Norman J. Temple is a professor of nutrition at Athabasca University and has published in the area of nutrition as it relates to health. A number of his reviews and opinion papers discuss aspects of nutrition research, such as the pitfalls of focusing on mechanistic research.
Prof. Temple studied in the UK, receiving a PhD in biochemistry. After his time in reseach in the UK, he went on to work in Puerto Rico and then Canada, where he is currently based. In addition to teaching nutrition courses at the university, he carries out research (both in Canada and South Africa) in the general area of diet and health. Prof. Temple has also published more than a dozen books.
