People with multiple sclerosis who for one year followed a plant-based diet very low in saturated fat had much less MS-related fatigue at the end of that year — and significantly less fatigue than a control group of people with MS who didn’t follow the diet, according to a study. “Fatigue can be a debilitating problem for many people living with relapsing-remitting MS,” said one researcher. “So this study’s results — showing some notable improvement in fatigue for people who follow this diet — are a hopeful hint of something that could help many people with MS.”
