A new study from ScienceDaily reports that omega-3 fish oil may help reduce insulin resistance even in individuals who are not obese. The research, conducted in diabetic rats, found that supplementation with omega-3 fatty acids improved blood sugar levels, cholesterol, and inflammation. Immune cells were shifted into a more anti-inflammatory mode, which is thought to drive these metabolic benefits.
These findings are significant because insulin resistance is a key driver of type 2 diabetes, a condition affecting millions worldwide. If replicated in humans, omega-3 fish oil could become a simple, accessible supplement for improving metabolic health, especially for those who are not overweight.
The study reported improvements in several markers including blood sugar levels, cholesterol, and inflammation in rats given omega-3. The mechanism involved reprogramming immune cells to reduce inflammatory signals, which can impair insulin sensitivity.
Future research will need to confirm these results in human clinical trials. If successful, omega-3 fish oil could complement existing diabetes treatments such as metformin and lifestyle changes.
Experts caution that these are animal model results and may not directly translate to humans, but they highlight a promising avenue for affordable intervention.
