Many British people believe they lead a healthy lifestyle when they actually do not, new research suggests.

A survey by PruHealth questioned 3,034 adults and found that nearly seven tenths believe themselves to be healthy.

However, responses to other questions suggest that many are deluding themselves.

For instance, less than half would describe their fitness levels as 'good'; only 24 per cent eat their recommended five daily portions of fruit and vegetables; and 21 per cent are smokers.

The survey also revealed that only 20 per cent feel free from stress and just 14 per cent go for regular GP check-ups and screenings.

Shaun Matisonn, PruHealth chief executive officer, said: "It's staggering that so many people in Britain are still failing to meet the minimum guidelines for exercise and diet, continue to smoke and drink heavily and yet believe themselves to be generally healthy."

The expert added that time and cost appear to be the main barriers to following a healthy lifestyle.

The Organisation of Economic Co-Operation and Development recently revealed that the UK's food prices are rising by more than ten per cent.
