A recent study from Brazil suggests that omega-3 fatty acids, found in fish oil, may help reduce insulin resistance even in individuals with type 2 diabetes who are not obese.

Using Goto-Kakizaki rats, an established model for non-obese diabetes, researchers administered fish oil over eight weeks and observed improvements in blood sugar regulation, cholesterol levels, triglycerides, and inflammatory markers.

The study indicates that omega-3 fatty acids may work by shifting immune cells, particularly lymphocytes, from a pro-inflammatory state to an anti-inflammatory state, which helps improve insulin sensitivity.

This research highlights that inflammation plays a central role in diabetes beyond obesity, suggesting potential benefits of omega-3 supplementation for non-obese diabetic patients.

While the findings are promising, they are based on animal models, and human clinical trials are needed to determine effective doses and confirm results.Related human studies have shown some improvements in insulin resistance and lipid profiles with omega-3 supplementation, but evidence remains mixed.

Overall, the study emphasizes the connection between inflammation and metabolic health in type 2 diabetes and identifies omega-3 fatty acids as a potential target for further research.
