Salt has overtaken the fear of food poisoning as the main concern for shoppers, according to a survey on behalf of he Food Standards Agency (FSA).

In the survey, six out of 10 people questioned said they were worried about the amount of salt in food and they recognised that salt was a significant factor in developing high blood pressure, which can lead to heart disease and stroke.

Salt was a concern for 57% of those asked in the survey, while 56% were worried about food poisoning and 53% specified their concerns about fatty food. Sugar was high up the list for 50% of those asked.

More than a third of those asked claimed to be eating more healthy diets than they were a year ago but 7% admitted it had got worse. However, 50% said they were now eating the recommended five portions of fruit and vegetables a day, which is a leap from the 28% logged in 2003.

The survey also found the 90% of those who took part continue to use supermarkets for most of their food shopping, but the number who buy from markets has risen from 19% in 2003 to 25% last year.
