What dietary strategy is recommended for psoriasis?

• A. Reduce arachidonic acid and increase omega-3
• B. Increase arachidonic acid and decrease omega-3
• C. No change
• D. Increase saturated fats

Answer: (A)

Inflammation in psoriasis can be influenced by the types of fats you eat. Arachidonic acid, an omega-6 fatty acid, is a precursor to pro-inflammatory eicosanoids. When intake of arachidonic acid is high, it can promote inflammatory pathways that may worsen psoriasis symptoms. Omega-3 fatty acids (EPA and DHA) compete with arachidonic acid for the same enzymes, and they tend to produce less inflammatory or even anti-inflammatory mediators.

So, reducing arachidonic acid intake and increasing omega-3 intake shifts the inflammatory balance toward anti-inflammatory signals, which can help improve psoriasis symptoms. Practical steps include cutting back on foods high in arachidonic acid (certain animal fats and processed foods rich in omega-6) and boosting omega-3 sources such as fatty fish (salmon, mackerel), flaxseeds, chia, and walnuts, aiming for a healthier omega-6 to omega-3 balance.
