Most 50 to 65 year old are aware of healthy eating guidelines, but many are failing to put their knowledge into practice.
A survey by the Food Standards Agency (FSA) found that almost a quarter of people in this age group agreed strongly with the statement that, 'life's too short to worry about what I eat'.
And more than a third concurred wholeheartedly with the sentiment, 'I've always eaten this way and it's done me no harm.'
Those aged 58 to 65 and those in lower social groups were the most likely to agree strongly with these statements.
The survey results were published at the same time as the FSA's new leaflet 'The Good Life', which gives practical advice to help the over-50s improve their diets and ward off heart disease, cancer and osteoporosis.
Rosemary Hignett, Head of Nutrition at the FSA, said: "Some people may worry that it's hard to change the habits of a lifetime, or that healthy eating will impinge on their enjoyment of food.
"But the straightforward, practical advice we offer doesn't demand huge changes in lifestyle and, contrary to what many people, may believe it's easy to eat healthily and enjoy your food."
