Omega-3 fish oil supplements reduce cardiovascular disease in diabetics
According to a new study from Tehran University of Medical Sciences in Iran, daily intake of omega-3 fatty acids may reduce levels of a trigger substance linked to heart disease in diabetics.
Results published in the peer-reviewed journal Nutrition, Metabolism and Cardiovascular Disease suggest that high doses of omega-3 fish oil daily (3 grams per day) cut levels of the amino acid homocysteine by 22%, compared with less than 1% in the placebo group.
81 diabetics took part in this randomised, double-blind placebo-controlled trial, which lasted two months with participants randomly assigned to either receive 3 grams of omega-3 or a sunflower oil placebo daily.
Previous research has linked increased levels of homocysteine with an increased risk of cardiovascular disease. By lowering levels of this amino acid in the blood, scientists believe it is possible to reduce their heart disease risk, providing support for the inclusion of omega-3s as part of the diabetic diet. Evidence is not yet conclusive however, and further research needs to be conducted before firm conclusions may be drawn.
The number of diabetics diagnosed with the disease soared by 70,000 in the UK between 2006-7, according to a report by the Information Centre for Health and Social Care.
According to their report, people affected by diabetes in the UK has climbed to 3.7 per cent, with a record number of 1,986,200 people diagnosed with the condition; a further 750,000 people are likely to have diabetes and not be aware of it. These figures paint a worrying picture for the health of the nation.
The Chief Executive of Diabetes UK, Douglas Smallwood, commented: “These figures are truly alarming as diabetes is a serious condition, which can lead to blindness, kidney failure, heart disease, stroke and nerve damage that can cause amputation . We need to do all we can to raise awareness of the condition and to encourage people to follow a healthy diet, and pursue an active lifestyle to help them reduce their risk of developing diabetes.”
When you consider that the impact of our 24/7 culture is that we tend to drive to work, drink a little too much, eat too few freshly prepared meals (not to mention that most of us are probably short on dietary fibre) you can appreciate why diabetes is becoming a real problem.
This is not to say that there’s nothing we can do about it, however. Simple changes to our diet and lifestyle and dramatically decrease our chance of developing diabetes and, if you’re affected already, it is definitely possible to influence the likelihood of associated health problems as the condition advances. As a nutrition scientist I would advise a diet with increased fibre, whole grains, few sugars, as well as cutting out the bad fats – this is actually a good approach for anyone.
I’d also add to the diet highly concentrated omega-3 fish oil containing pure EPA, an active component of fish oil which is especially beneficial for reducing the risk of complications in the cardiovascular system. OmegaForce is ideal in this respect, as it combines with pure EPA the omega-6 GLA (highly anti-inflammatory) with the omega-9 oleic acid from olive oil, its benefits associated with the healthy Mediterranean diet.
