Nutrition and Diet
Maintenance of general good health is very important for persons with MS or any chronic disorder. A well-balanced and carefully planned diet will help to achieve this goal. MS specialists recommend that people with MS adhere to the same low-fat, high fiber diet that is recommended for the general population.
The Problem with Special Diets
While many different diets have been proposed as a treatment, or even a cure, for the signs and symptoms of MS, evidence of effectiveness is very limited. There is some evidence that a diet low in saturated fats and supplemented by Omega 3 (from fatty fishes, cod-liver oil, or flaxseed oil) and Omega 6 (fatty acids from sunflower or safflower seed oil and possibly evening primrose oil) may have some benefit for people with MS.Most of the diets that have been touted as helping people with MS have not been subjected to rigorous, controlled studies, and the few that have been evaluated have produced mixed results. Most of the claims made for dietary treatments are based on personal accounts, and the reported benefits may have been spontaneous changes that would have happened without any treatment.
Some Diets May Be Harmful; Others Are Fine
Some special diets may be harmful because they include potentially toxic amounts of certain vitamins, or exclude important nutrients. Others conform to the low fat, high fiber diet recommendations of the American Heart Association and the American Cancer Society for all Americans.
Vitamin D
It’s well known that vitamin D works to promote calcium absorption for strong bones. However, recent research also suggests that vitamin D may have important effects on the immune system and may help regulate cell growth and differentiation.
