Cheese comes from plants, tomatoes grow underground and fish fingers are made of chicken - at least that is according to children in Britain and Northern Ireland.
A new poll suggests confusion among children about the origins of their foods, with even some teenagers unsure how some items find their way on to a dinner plate.
Nearly a third (29 per cent) of five to seven-year-olds thought that cheese came from a plant, not an animal, while one in four older primary school pupils (aged eight to 11) thought the same.
In addition, just over one in five (22 per cent) of the infants, and 13 per cent of the older primary group believed that animals provide us with pasta.
There was also uncertainty about other foods, with 22 per cent of five to seven-year-olds saying prawns come from plants and 20 per cent suggesting that chips are made of animals.
Among the eight to 11-year-olds questioned as part of the British Nutrition Foundation (BNF) poll for its Healthy Eating Week, there was less slightly confusion, although 10 per cent thought that bread came from animals.
While 73 per cent of five to seven-year-olds and 92 per cent of eight to 11-year-olds knew that fish fingers are usually made from haddock or cod, 18 per cent of the younger pupils thought they were made of chicken, along with 6 per cent of the older group.
Around one in 10 (11 per cent) of 11-14-year-olds and a similar proportion of 14-16-year-olds (10 per cent) thought that tomatoes grow underground, with 40 per centof the younger age group saying they grow on a vine and 22 per cent saying on a bush (49 per cent and 18 per cent respectively for the older age range).
Some 11 per cent of both 11-14-year-olds and 14-16-year-olds thought that fruit pastilles counted towards their five-a-day, while 27% of the younger group and 26 per cent of the older range thought that they could include strawberry jam as part of their daily fruit and veg.
The findings did show that 31 per cent of 11-14-year-olds and 28 per cent of 14-16-year-olds say that they know lots about healthy eating and try to follow it, while almost half of the younger group and 48 per cent of the older children say they know lots but either do not follow it or do not always follow it.
Roy Ballam, BNF managing director and head of education said: "Schools and families can and should successfully work together to, in turn, educate children and then motivate them in their endeavours to make healthier choices.
"Furthermore, the links between physical activity, health and diet should be frequently highlighted by the government's programmes."
