The Food for Thought report by TNS, part of market research company Kantar, found that only a third of UK respondents agreed with the statement "I am at risk of the food that I eat damaging my health" - joint lowest among the seven nations surveyed.
Even amongst the obese, 67 per cent internationally believe their eating habits are healthy. "Paradoxically, the USA and UK, two countries with high obesity levels, are most confident in their assertion that their diet is good for their health," the report concluded.
Nearly twice as many French consumers as British were concerned about the health value of their food. Yet France comes second in the Economist Intelligence Unit's international table of food quality and safety, compared to the UK's 17th place.
