One or two servings of fish a week will reduce your chances of getting heart disease, because it's rich in omega-3 fatty acids.

Next time you're passing your local fish market, pull up, get out of the car, part with some money and take home some fish. You'll live longer than those people who've driven on by without stopping.

That's the conclusion of an increasing number of studies showing that eating fish regularly lessens your chance of getting heart disease, and might help other medical conditions too.

Not only is fish is high in protein and low in fat, it contains a type of polyunsaturated - or 'good' - fat, called omega-3 fatty acids. There are two main ones in fish: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). They're thought to act as natural anti-inflammatory agents.
