This is the protocol for a review and there is no abstract. The objectives are as follows:
The aim of this systematic review is to assess the efficacy and safety of a dietary intervention on the usual diet of MS patients which would be expected to modify the course and prognosis of MS or at least improve the health status of people with the disease.
We will address the following primary questions:
1. Are changes of nutritional habits an effective intervention for MS patients?
2. Are potential side effects of these interventions known and measured?
3. Have potential interactions between dietary intervention/supplementation and other curative or symptomatic treatments been studied?
