A Brazilian study found that fish oil supplements reduced insulin resistance and inflammation in rats modeling non-obese type 2 diabetes. The research highlights a potential role for omega-3 fatty acids in cases where obesity is not a factor.
Researchers at institutions including the Butantan Institute gave Goto-Kakizaki rats fish oil three times a week for eight weeks. The dose equaled 2 grams per kilogram of body weight and contained specific amounts of EPA and DHA. Treated animals showed lower insulin resistance, improved blood sugar control, reduced inflammatory markers, and better cholesterol and triglyceride levels.
