Does Eating Fish Reduce Rheumatoid Arthritis Symptoms?

According to a recent study eating fish may reduce symptoms of rheumatoid arthritis.

by Dr. C.H. Weaver M.D.

Eating fish two or more times per week appears to be associated with lower disease activity in patients with rheumatoid arthritis (RA), according to an analyses published in Arthritis Care & Research.1

Previous research has suggested that fish oil may reduce the disease activity of RA. The benefits from fish consumption are thought to be from the anti-inflammatory effects of omega-3 fatty acids.2

In order to further evaluate the impact of dietary fish consumption doctors performed an analyses using data collected from 176 participants in the Evaluation of Subclinical Cardiovascular Disease and Predictors of Events in RA (ESCAPE-RA) ongoing cohort study. The researchers analyzed the association between frequency of fish consumption and baseline RA disease activity. They also estimated the impact associated with increasing fish consumption by one serving per week.

Frequency of fish consumption was assessed by a questionnaire documenting baseline food frequency consumption in the past year. Fish consumption was stratified as never to less than one serving/month, one serving/month to less than one serving per week, one serving per week, and two or more servings per week. Fish consumption was defined as “tuna fish, salmon, sardines (cooked or raw including sashimi or sushi),” and “other broiled, steamed, baked or raw fish (trout, sole, halibut, poke, grouper, etc.).”

The authors found a clinically significant reduction in RA disease activity in individuals who consumed fish ≥2 times/week compared to those who consumed fish never or <1/month. Moreover, each additional serving of fish per week was associated with an additional reduction in disease activity.

The researchers concluded that higher intake of fish “may be associated with lower disease activity in RA patients.” It cannot be known for certain however whether these results are due to a generally healthier lifestyle among those who eat fish most often, or may reflect an effect of consuming fish as a whole food that contains various macronutrients and micronutrients in addition to omega-3 fatty acids.

Do not be afraid to eat fish, especially oily fish, such as cod, salmon, altus, saury, mackerel, eel. These varieties of fish contain a large percentage of fish oil (Omega-3). They reduce the concentration of harmful cholesterol in the blood, thereby beneficially affecting the state of the brain, heart, blood vessels and eyes. Especially you need to give such fish to children, because they have to think a lot and they are quite active. It helps on both sides - your children will not have rheumatoid arthritis (PA), they will also be saturated with poly non-saturated fats and their brains will work very smoothly. Do not forget that children should not only eat right, but also play sports in order to maintain health for many years. Therefore, there is one very good writing site - https://au.edubirdie.com/, where I ordered some works for my son in order to free his time for sports. Do not forget to take care of your children!

Yes, changing my diet has drastically improved my RA symptoms. In addition to eating fish, I make sure to have a high quality fish oil supplement. I have been told by my nutrionist though, to only eat certain types of fish as some that are known to have high mercury in them, can be problematic for those living with RA.

Curious if anyone has modified their diet to help with RA andif it worked? A diet rich in fish appears has many benefits - would be great if it helped lower RA disease activity.
