Dr Sean Mark, of Approach Analytics and Science for Ourselves, is a Canadian epidemiologist, nutrition scientist and social entrepreneur. He is leading a gifted team of data scientists and web developers to create a virtual wellness app/platform that can shape health policy. Why? Dr Mark says that the ivory-tower science model is not creating effective tools to address the obesity and diabetes pandemic. He and his team are building a “bottom-up“ health information paradigm that puts peoples‘ and practitioners‘ needs at its center. They have a pre-production app that is live on the Nutrition 2.0 website. It aims to provide assumption-free, individualised nutrition. The platform will also have capacity to provide near-real-time data on the health economics of therapeutic diets.
