Too few Swiss watch what they eat, according to the findings of the latest survey published by the Federal Health Office on Monday.
Fewer than a third of those asked said they ate five portions of fruit and vegetables a day, and only ten per cent consumed the recommended minimum amount of dairy products.
The results of the 2007 survey, carried out by the Federal Statistics Office, found that 29 per cent of the Swiss are overweight (38 per cent of men, 21 per cent of women) and eight per cent are obese.
On the positive side, there has been no significant increase in the percentage of overweight people since 2002.
The authors of the study said there has been little improvement in the eating habits of the Swiss since the first survey was carried out 15 years ago.
Particularly at risk of disease due to their unbalanced diet are young, poorly educated men.
