Unsaturated Fats Can Relieve Multiple Sclerosis Symptoms, According to New Study

Reading Time: 2 minutes

Basic nutrition teaches that fat, when consumed in large quantities, is harmful to human health. However, the components that make up fats are complex. Good, unsaturated fats, or lipids, can lower disease risk.

In a new study, researchers found that a good fat derivative may be able to relieve symptoms in patients suffering from chronic inflammatory diseases, such as multiple sclerosis. The findings were published in the Journal of Biological Chemistry.

The study was conducted by Justin Kim, a postdoctoral fellow at the Georgia Institute of Technology, Aditi Das, an associate professor of chemistry and biochemistry at Georgia Tech, Andrew Steelman, an associate professor of animal sciences at the University of Illinois at Urbana-Champaign, and their colleagues.

Multiple sclerosis (MS) is a chronic, autoimmune disease of the brain and spinal cord during which the immune system attacks the cells and tissues that protect nerve fibres. This potentially debilitating disease can cause pain, vision loss, fatigue, impaired cognitive function and more. There is no cure for MS, and it affects almost 1 million people nationwide.

The researchers specifically looked at docosahexaenoyl ethanolamide (DHEA), a derivative of the lipids found in cold-water fish and fish oil supplements, and its impact on the immune system. Interestingly, DHEA has been shown to be anti-inflammatory and has similar properties to cannabis in some contexts.

“Our goal was to use something that is naturally found in food and the human body to see if we can enhance it to reduce the disease severity in multiple sclerosis patients,” Das said.

Using a common mouse model that closely mimics the relapsing and remitting nature of MS, Kim, Steelman and Das noticed that DHEA is at its highest concentration in the mice when they are in a state of remission, which prompted them to consider if DHEA could dampen the inflammation that controls the disease.

“We thought if we could somehow alleviate, control or reduce the level of inflammation, we could improve the disease outcomes and severity,” Kim explained.

Even though taking fish oil supplements has been linked to improved quality of life in patients with inflammatory conditions, the interworking of this association has never been teased apart in MS, until now. Kim, Steelman and Das were the first to show that the DHEA lipid can reduce inflammation and disease signs in a mouse model of MS. The researchers found that, when they supplemented the diet of mice with DHEA, the mice showed less severe and later onset of MS-like disease. This reduction is likely due to the presence of fewer activated, pathogenic T cells in the central nervous system, the research team found.

“We believe our findings could lead to the discovery of new solutions to aid in managing symptoms of multiple sclerosis and other chronic inflammatory diseases like diabetes,” Das said.

So, should you start taking fish oil supplements? First, more work is needed to study how DHEA affects other parts of the immune system and humans. However, the researchers are optimistic that this is a step forward in using naturally occurring good fats or their derivatives to lower inflammation without the negative side effects of some currently prescribed medications.

“I’ve seen that a lot of patients with multiple sclerosis are fully in tune with the research,” Kim said. “They are always trying to do everything that they can to improve their symptoms, whether it be through exercise, diet or just healthy living while trying to reduce their consumption of heavy pain medications.”
