Dairy and MS

OMS strongly advises that people with MS avoid dairy in their diet because research shows a high correlation between MS and dairy products, specifically because of particular proteins in cow’s milk.

OMS strongly advises people with MS to avoid consuming dairy products. Research shows a high correlation between MS and dairy milk, due to proteins in cow’s milk.

Three pieces of evidence:

  1. Some of the proteins in cow’s milk are targeted by the immune cells of people with MS. These include butyrophilin and bovine serum albumin (BSA).
  2. Injecting those same cow’s milk proteins into test animals caused lesions to appear in their central nervous systems.
  3. 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. This can trick the immune system into initiating an attack on MOG and hence cause demyelination.

Dairy and general health

In terms of general health, a research study involving more than 135,000 men and women in the U.S. linked cow’s milk to the degenerative neurological disorder Parkinson’s Disease. Researchers speculate that dairy products may have a generally toxic effect on nervous tissue.

Lactose intolerance is common in many populations around the world (most notably Mediterranean, Asian, and African). Lactose-intolerant people experience a variety of ill effects from milk, including bloating, cramps, diarrhea, and nausea.

In their best-selling book The China Study: The Most Comprehensive Study of Nutrition Ever Conducted and the Startling Implications for Diet, Weight Loss, and Long-Term Health, Drs. Thomas Campbell and T. Colin Campbell argue that the best diet for overall human health is a plant-based diet of whole foods. For people with MS, the book is interesting reading, as it links animal fat and protein, especially cow’s milk, with MS and a range of other Western diseases.

Given the high potential risks for people with MS of consuming dairy products, despite a lack of conclusive evidence, OMS recommends avoiding cow's milk products as part of the OMS Recovery Program.

Dairy alternatives for those on the OMS diet

Alternatives to dairy are widely available in a range of substitutes for milk, cheese, ice cream, yogurt, and even butter. These are made from such foods as almonds or nuts, hemp, rice, oats and soy. You can even make your own. 

While soy products offer the highest protein and are better for baking, some people think almond or rice milk taste better on cereal. (Note we do not recommend coconut milk). 

Check the ingredients as some alternative milks contain oil which is restricted on the OMS Program.
