OMS strongly recommends that you avoid all dairy products as part of the OMS Recovery Program.
Research shows a strong connection between MS and cow’s milk.1,2 Particular proteins in milk have been shown to a) stimulate the immune cells of people with MS and b) cause lesions to appear in the central nervous systems of test animals.3,4
Some proteins in cow’s milk mimic part of myelin oligodendrocyte glycoprotein (MOG), the part of myelin thought to initiate the autoimmune reaction in MS.5
Alternatives to dairy are widely available in a range of substitutes for milk, cheese, ice cream, yogurt, and even butter. Some are calcium-fortified, if that’s what you prefer. Some people are concerned they won’t get enough calcium if they eliminate dairy, but a plant-based whole-food diet contains plenty of calcium. A key issue here is getting adequate sun exposure or vitamin D in supplements to ensure calcium is absorbed from food.
OMS does not recommend any kinds of animal-based milk, including that from goats and sheep.
