The old advertising slogan "Guinness is Good for You" may be true after all, according to researchers.

A pint of the black stuff a day may work as well as a low dose aspirin to prevent heart clots that raise the risk of heart attacks.

Drinking lager does not yield the same benefits, experts from University of Wisconsin told a conference in the US.

Guinness was told to stop using the slogan decades ago - and the firm still makes no health claims for the drink.

Personally, I just wish the boffins would make their minds up. It seems we have a new "scientific report" every week and all they ever do is disagree with the last one that came out. Only a couple of weeks ago I read a report which says all the stuff we've been told about red wine and antioxidants helping reduce the incidence of cancer is no longer considered to be true.

Next year it will be good for you again.

And olive oil will be bad, but they will discover that mayonnaise is a cure for heart disease...

Do they really get paid for this stuff? Give me a job like that.
