The posters have been launched by the British Heart Foundation and aim to get children thinking about what food choices they make. They direct people towards the , which has a special section devoted to the campaign.
The images parody fast-food menus, but instead of showing a tasty burger, the patty has been replaced with an image of raw, fatty meat. Another is headlined "chicken nuggets", but shows a pile of chicken skin and fat, while the image of a hotdog shows a bun filled with gristle.
All the poster images carry a "censored" sign over the food, although the website contains uncensored images, should users choose to view them.
The BHF started to target children after a survey showed that 36% of children aged between eight and 14 did not know that chips were made from potatoes.
Peter Hollins, director-general of the BHF, said: "It sends a shiver down my spine to discover that so many children don't even know what chips are made of. Kids have lost touch with even the most basic foods and no longer understand what they are eating."
Earlier this year, the chef Jamie Oliver was shown on the Channel 4 series 'Jamie's School Dinners' persuading children to eat his healthy food by demonstrating the ingredients that go into chicken nuggets, including skin and fat.
