Reduced retina DHA in diabetesRetinal Docosahexaenoic Acid Is Significantly Reduced in Diabetic Humans and Mice: Possible Relationship to Diabetic Retinopathy.
We investigated the impact of diabetes on the levels of docosahexaenoic acid (DHA), an essential omega 3 fatty acid, in the retina of humans and mice. Our findings revealed that diabetic individuals had significantly lower DHA levels—40% less in peripheral regions and 25% less in the macula—compared to those without diabetes.
Additionally, we observed a reduction of retinal thickness and function in diabetic mice. Although there’s potential for dietary DHA to help with diabetic retinopathy, the current study suggests that diabetes is linked to reduced DHA and related retinal defects.

Omega-3 fish oil shows promiseOmega-3 Fatty Acids Weaken Lymphocyte Inflammatory Features and Improve Glycemic Control in Nonobese Diabetic Goto-Kakizaki Rats.
We examined the impact of omega-3 fatty acids from fish oil on diabetes in nonobese Goto-Kakizaki rats. Over eight weeks, these rats received fish oil supplements, while control groups were given plain water.
Our findings revealed that fish oil significantly enhanced glucose tolerance and insulin sensitivity in the diabetic rats. Additionally, it shifted T lymphocyte activity towards more immune-regulating patterns, reducing inflammation and promoting better overall metabolic health.
However, the study primarily involved animal models, so further research is needed to confirm these results in humans.

Omega-3 lowers type 2 diabetes oddsThe relationship of dietary omega-3 fatty acid and omega-6 to omega-3 ratio intake and likelihood of type 2 diabetes in a cross-sectional study.
We conducted a study analyzing dietary omega-3 and omega-6 fatty acids and their connection to type 2 diabetes (T2DM) risk. Using data from 8,744 participants, we found that higher omega-3 intake was linked to a 58% lower chance of developing T2DM.
In contrast, a high omega-6 to omega-3 ratio appeared to increase the likelihood of T2DM. However, dietary omega-6 on its own didn’t show a significant effect in relation to diabetes risk. These findings suggest that enhancing omega-3 intake might be beneficial in managing T2DM risk.

DHA shows potential stroke protectionDocosahexaenoic acid protects against ischemic stroke in diabetic mice by inhibiting inflammatory responses and apoptosis.
We aimed to understand if docosahexaenoic acid (DHA) could protect diabetic mice from ischemic stroke. After administering DHA, we observed a significant reduction in brain injury and improved neurological function in these mice after stroke.
The treatment appeared to lower inflammation and cell death, as indicated by less neutrophils in the brain and changes in important proteins. Overall, DHA showed promise in managing stroke's damaging effects in diabetic models, suggesting potential benefits for clinical practice in diabetes care.

Omega-3 reduces inflammation, diabetes riskEPA and DHA inhibit LDL-induced upregulation of human adipose tissue NLRP3 inflammasome/IL-1β pathway and its association with diabetes risk factors.
We tested the effects of omega-3 fatty acids, specifically EPA and DHA, on diabetes risk factors linked to high levels of "bad" cholesterol. Over a 12-week period, individuals with elevated lipoprotein levels received daily omega-3 supplements.
We found that this intervention significantly reduced inflammation in fat tissue, improving factors like insulin function and fat metabolism. Overall, omega-3 supplementation showed promising results in lowering diabetes risk through its positive effects on inflammatory pathways.
However, while benefits were observed, the results indicated the need for further studies to fully understand the long-term impacts.
