Health Benefits of High Omega-3 Index in Psoriasis

Omega-3 Fatty Acids

Omega-3 is a class of fatty acids, which includes eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). It is the most beneficial of all fats in your body. There are multiple beneficial effects for your health.

Omega-3s possess significant anti-inflammatory properties. These work by inhibiting the function of enzymes that synthesize the inflammatory mediators. Without enough mediators, inflammation discontinues and the symptoms get relieved.

Psoriasis is a lifelong (chronic) skin disease that causes red, cracking dry, and itching scaly patches on your scalp and the skin of your elbows, trunk, and knees. It occurs because your immune system reacts to your own skin, causing your skin cells to reproduce at a more-than-normal pace. Continuous inflammation in the skin mainly causes the symptoms of the disease.

Among many other treatments, dietary intake of omega-3 fatty acids has shown promising effects in many psoriasis patients.

What is the Omega-3 Index?

The omega-3 index is a measure of the amount of omega-3 fatty acids (EPA and DHA) in your blood, especially the red blood cells’ membranes. It measures the percentage of omega-3s out of total fats (different types) in a cell membrane. It gives an estimate of the total omega-3s levels in your body. It simply tells about how much omega-3s you take from your diet. It is a direct biomarker for the risk of cardiovascular diseases, and some inflammatory diseases (including psoriasis).

OMEGA-3 index = 8 – 11

An omega-3 index value of 8 to 11 is considered optimal for good health. It reduces the risk of many life-threatening diseases like heart attack, stroke, and other inflammatory diseases.

Health Benefits of High Omega-3 Index in Psoriasis

A high omega-3 index simply means that you have high amounts of omega-3 fatty acids in your body. Studies have shown multiple health benefits of high omega-3 index in your body.

It helps reduce the redness and itchiness of the scaly plaques. It also improves the other factors playing a role in healthy skin.

A 2014 study, published in the Journal of American Academy of Dermatology, showed that the use of fish oil is beneficial for psoriasis patients.

According to another study, published in the Journal of Clinical Nutrition, showed that obese individuals who also had psoriasis, significantly improved their symptoms when they followed a low-calorie diet that also contained omega-3 fatty acids.
