This is lay-translated by me from the website of the danish MS-society:
"Diet and Multiple sclerosis
For more than 50 years one has gathered experiences and conductet research on the relationship between diet and multiple sclerosis. Research show a positive effect after a change of diet - both with the frequency of attcks, movement/tonus (da:'förlighed') and quality of life.
New scientific research support practical experience: Disease activity is significantly reduced if animal fat and dairy products are replaced with oil of fish and certain plants.
After working several years with collecting the existing research, ms-patient and medical journalist Gunda Rademacker Jensen in cooperation with the diet-group in ms-hospitals has developed this dieting guide."
The guide itself and much more information is also on the site, including a list of seven points for a healthy ms-diet. My translation of the seven points:
1. Meat: Max. 2 times per week
2. Egg: Max. 2 per week
3. Milk-products: Only low-fat
4. Fish: 2-3 times a week
5. Vegetable oil (plant-oil): 1-3 tblsp. daily
6. Fruit and Green: Daily
7. Intolerance: Avoid what you do not tolerate
