What is Omega-6 to Omega-3 Ratio?
A comparison of how much omega-6 fat you have relative to omega-3 fat in your blood.
This ratio compares your omega-6 fatty acids (common in many vegetable oils and processed foods) to your omega-3 fatty acids (from oily fish and some plants), reported as a single number rather than a concentration. A higher ratio is sometimes discussed in nutrition research as reflecting a diet heavier in omega-6 and lighter in omega-3, and can be associated with a more inflammatory dietary pattern. The ideal ratio is debated, and this is an optional, research-oriented marker rather than a routine test.
