Professor George Jelinek and his team at the University of Melbourne have published various cross-sectional studies demonstrating an association between less disability and better quality of life in people with MS who consume more fruits and vegetables, less saturated fat, and less processed food. But does diet now correlate with progression of disability of MS over many years? This prospective study compares diet with MS disability, fatigue, and quality of life 7.5 years later. My conflicts of interest are explained in the video.
