A recent national survey, commissioned by Woolworths, found that a third of Australian children struggled to identify fruit and vegetables, and were confused about where produce came from.
The study, which surveyed 1601 Australian children aged between six and 17 years, revealed 92 per cent did not know bananas grew on plants.
"Three-quarters of Australian children in their final year of primary school believe cotton socks come from animals and 27 per cent are convinced yoghurt grows on trees," reported Fairfax.
In fact, 75 per cent believed cotton was an animal product.
British primary school kids are just as clueless as Australian children.
In 2013, a British survey found that almost a third of the country's primary school children thought cheese was made from plants and a quarter thought fish fingers came from chicken or pigs.
The poll, conducted by the British Nutrition Foundation, surveyed about 27,500 children aged between five and 16 years, and found there was also some confusion about where pasta and bread came from.
"A third of five-to-eight-year-olds believe that they [pasta and bread] are made from meat," reported the BBC.
According to another survey, young adults in Britain are none the wiser.
The online poll, led by the charity LEAF (Linking Environment and Farming), surveyed 2000 people aged between 16 and 23 years and found a third of them did not know that bacon came from pigs.
Researchers also found that four in 10 young adults did not know where milk came from, with 40 per cent of them failing to recognise the link between milk and a picture of a dairy cow.
Kids still don't know where their food comes from
