Catch this month’s conversation with Dylan Mackay from University of Manitoba, Winnipeg, Manitoba, Canada. Dr. Mackay is a nutritional biochemist, specializing in human clinical trials and inter-individual variability. I focus on how phenotype and genotype modulate an individual's response to dietary interventions. The lead author of the paper, Dr. Samar Ahmad was unable join the conversation from her clinic in Kuwait. However, you are still in for a treat with the topic of this month’s episode on "The effect of sucralose and aspartame on glucose metabolism and gut hormones."
