How are Omega-3 Index and blood sugar related?

The provided context does not contain direct evidence linking the Omega-3 Index to blood sugar. In general, some studies suggest that omega-3 fatty acids may improve insulin sensitivity, but results are mixed and depend on dose, baseline status, and genetics. A high Omega-3 Index (≥8 %) is often associated with a favorable cardiometabolic profile, but a direct causal effect on fasting glucose is not well established. The context includes SNPs like rs10830963 (glucose) and rs2764264 (FOXO3), but none relate to omega-3. Therefore, the evidence is unclear. Without specific data, any claim about the Omega-3 Index and blood sugar should be considered speculative. Omega-3 supplementation is not a substitute for a balanced diet or medical advice for glycemic control.
