What is a potential long-term effect of a high omega-6 fatty acid diet?

• A. Decreased risk of inflammatory diseases
• B. Increased inflammation and inflammatory diseases
• C. No effect on inflammation
• D. Immediate allergies

Answer: (B)

High omega-6 intake tends to push the body's inflammatory pathways toward a pro-inflammatory state. Omega-6 fatty acids are converted into arachidonic acid, which is a building block for eicosanoids like prostaglandins and leukotrienes that promote inflammation. When this happens chronically, especially if omega-3 intake is low, the balance shifts toward more inflammation, which over time can contribute to inflammatory diseases such as atherosclerosis, arthritis, and inflammatory bowel conditions. This is why the long-term effect is better described as increased inflammation and inflammatory diseases.

Noticing the other possibilities helps connect the concept: a high omega-6 pattern isn’t linked to decreased inflammation or no effect, and it isn’t typically associated with immediate allergic reactions; those responses involve different immune triggers and timing. The key idea is the long-term pro-inflammatory potential from excess omega-6 relative to omega-3.
