Nutrition Reviews: Conversations with the Authors

By James Cameron
Nutrition Reviews is published by Oxford University Press and is an international, peer-reviewed journal that publishes authoritative and critical literature reviews on current and emerging topics in nutrition science, food science, clinical nutrition, and nutrition policy. Each month we talk with authors who have contributed to Nutrition Reviews to find out who they are, why they wrote their review and how they think the review should be used to advance nutritional sciences.
