Research Findings on Omega-3 Fatty Acids
There is somewhat more literature available on omega-3 supplementation as a possible remedy for
diabetes than for most other alternative treatments for this condition. The Cochrane Collaboration published a 2001 analysis of 18 randomized placebo-controlled trials on
fish oil supplementation in type 2 diabetes. The authors found that fish oil lowered
triglycerides and raised
LDL cholesterol but had no significant effect on fasting blood glucose, HbA1c, total cholesterol, or
HDL cholesterol. (The authors did not identify and include studies with cardiovascular outcomes, but noted that this is an area for further research.)
In 2004, another analysis was published by the Agency for Healthcare Research and Quality of 18 studies on
omega-3 fatty acids for a number of measurable outcomes in type 2 diabetes. This study confirmed virtually all the Cochrane authors' findings, except for finding no significant effect on LDL cholesterol.
Additional studies are needed to determine whether omega-3 supplements are safe and beneficial for heart problems in people with type 2 diabetes. Studies that look specifically at
heart disease outcomes in this population are needed.
