Researchers from the University of East Anglia have found that omega-3 fish oil supplements offer no benefit for people with type 2 diabetes. The review, published in the BMJ, analysed more than 80 studies and concluded that the supplements had little or no effect on diabetes diagnosis or glucose metabolism.
Lead researcher Dr Lee Hooper said there had been concerns that omega-3 could be harmful for those with the condition, but the study found no evidence of harm. However, it also failed to find any benefit, leading the team to recommend that people with type 2 diabetes should not be encouraged to take the supplements.
Diabetes UK advised that it is better to obtain omega-3 from eating oily fish as part of a healthy diet. Douglas Twenefour, deputy head of care at the charity, said: 'While omega-3 fatty acids are crucial for our overall health, it's generally better for people with type 2 diabetes to get their intake by eating at least two portions of oily fish a week, than by taking supplements.'
Dr Hooper added: 'This is really expensive stuff. If somebody's at risk of diabetes, there are much better things to spend money on, like a physical activity - or oily fish.' However, Dr Carrie Ruxton from the industry-funded Health and Food Supplements Information Service argued that a daily omega-3 supplement could bridge the gap for those who do not eat enough fish.
