Fish products contain two main omega-3 fatty acids, called Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA).
A new study at UEA’s Norwich Medical School aims to identify whether EPA or DHA is the most effective at improving blood vessel function and reducing the risk of heart disease and stroke.
Researchers are looking for men aged 35-55 who are non-smokers and without a history of heart disease, diabetes or cancer.
They also cannot be taking blood pressure or cholesterol-lowering drugs, or omega-3 supplements.
Prof Anne-Marie Minihane, who is leading the study, said: “Recent evidence indicates that part of the reason omega-3 fatty acids benefit humans is because they improve the ‘elasticity’ of major arteries.
“This could help to prevent heart disease and stroke and other health problems such as dementia, and the volunteers in this study will be instrumental in advancing current knowledge in this area.”
Participants will be asked to attend a clinic at UEA three times over four months. During these visits they will have blood samples taken before and after consuming a chocolate-flavoured drink containing different kinds of omega-3 fats, along with non-invasive measurements of blood vessels.
Volunteers are ideally required to live in Norfolk. A payment of £150 will be given to all who take part upon completion of the study.
