How Omega-3 Fats May Help Calm Chronic Inflammation and Support Immune Balance

This review article looks at how omega-3 fatty acids (like EPA and DHA found in fish oil) interact with the body’s inflammatory and immune processes. The authors explain that modern diets have shifted heavily toward omega-6 fats, which tend to promote inflammation, while omega-3 fats tend to have the opposite, calming effect. Keeping a healthy balance between these two types of fat is described as an important part of overall diet quality.

The paper summarizes findings from many prior studies, noting that omega-3 supplementation has been linked to reduced disease activity markers in autoimmune conditions such as type 1 diabetes, rheumatoid arthritis, lupus, and multiple sclerosis. It also references research on viral illness, including COVID-19, where omega-3 intake was associated with better reported outcomes in some studies.

Beyond autoimmune and viral illness, the review discusses research connecting omega-3 intake to improvements in blood lipids, fatty liver measures, body weight, cognitive function, and cardiovascular markers, particularly in aging populations and those with chronic kidney disease. The authors note that omega-3s also appear linked to lower levels of general low-grade inflammation associated with aging.

Importantly, the authors emphasize that pathophysiology of autoimmune diseases remains unclear and that more randomized clinical trials are needed to confirm proper dosing and effectiveness before firm conclusions can be drawn.
