The company has added omega 3 fatty oils, which tackle heart disease and help keep nails, skin and hair healthy.

It comes after the firm cut up to 60 per cent of the salt and sugar from its tinned pastas.

Omega 3--found in oily fish like salmon and herring--also improves brain function and concentration in hyperactive children, it is claimed.

"It doesn't taste fishy or anything," Heinz spokesman Nigel Dickie was quoted by the Sun, as saying.

The British Nutrition Foundation has endorsed the move--but stressed there were different types of omega 3.

A spokeswoman said the kind being added to the spaghetti would not necessarily be as good as that found in fish or other natural sources.

"Anything to boost the amount we're consuming is good," she added. (ANI)
