Researchers hoping to discover more about the health benefits of oily fish are looking for volunteers to take part in a study.
Volunteers will be asked to take fish oil capsules and visit the team
A team at the University of Reading wants to see if fish oil capsules help men and women stay healthy.
They need people aged 20 to 40 to take fish oil supplements and visit the university's nutrition unit.
Fish oils have often been shown to cut heart disease risk, but studies have focused mainly on middle-aged men.
The organisers of the Fingen Study have already recruited some volunteers, but are particularly keen for young people to join in the next phase.
The research is funded by the Food Standards Agency and also involves the universities of Glasgow, Newcastle and Southampton.
Anyone aged 20 to 40 who is interested in taking part is asked to call Jan Luff on 0118 378 7771.
