Peppa Pig making 'children naughty', parents fear George Pig, who my son loves, says 'Yuck' at vegetables and only wants to eat chocolate cake. A day after watching that episode, mine wouldn't eat his cucumber and tomatoes. Another anxious mother wrote: "My daughter keeps saying 'No' and 'Yuk' in a really high and mighty way, just like Peppa does, and generally answering back when I ask her to do something. Shall I ban Peppa Pig, or is that being totally unreasonable? Psychologist Dr Aric Sigman said in recent years there had been a "significant increase" in children using "adversarial, snide, questioning, confrontational and disrespectful behaviour," which he attributed to cartoons. There is nothing special about Peppa Pig - the same applies to all programmes. Some 80 per cent of brain development is between birth and three years old, so if they spend a lot of time watching the TV, they will copy the forms of behaviours that they see on the TV," he told the Daily Mail. The problem is you can't distinguish to children what is real and pretend. You can't just say to the child the pig was only pretending to be naughty. In a survey published by the Department of Health last year, Scooby Doo, which features a cowardly Great Dane with an insatiable appetite for snacks and giant sandwiches, was found to be the healthiest of all children's television programmes. Stars of the long-running television series also took half of the places in a list of the most active individual characters, ahead of energetic animals such as Tom and Jerry and Wile E Coyote. Consultants drew up the league tables by watching 200 hours of children's television, featuring the 20 most popular programmes, and noted how many times physical activity was shown. "Each character was rated on their activity levels and received marks for good behaviours such as walking short journeys and playing sport," according to the Department of Health. Because much of the action in the cartoon shows Scooby and his gang running away from monsters, they topped the list. However officials at the health ministry were at pains to insist they were not holding up Scooby Doo, famed for his love of Scooby Snax, as a healthy role model. Anne Milton, the Public Health Minister, said: "Eating well and being active is crucial, especially at an early age. :: Top 20 children's programmes ranked by levels of physical activity Scooby Doo Shaun the Sheep Lazy Town Peppa Pig Bob The Builder Tom and Jerry Dora the Explorer Looney Tunes SpongeBob Squarepants In the Night Garden Ben 10 The Simpsons Phineas and Ferb The Sarah Jane Adventures Tracey Beaker Postman Pat iCarly Horrid Henry Garfield Charlie and Lola. :: The healthiest individual characters Sportacus, Lazy Town Scooby Doo, Scooby Doo Daphne Blake, Scooby Doo Shaggy, Scooby Doo Freddie Jones, Scooby Doo Stephanie, Lazy Town Jerry, Tom and Jerry Peppa Pig, Peppa Pig Tom, Tom and Jerry Velma Dinkley, Scooby Doo George Pig, Peppa Pig Shaun , Shaun the Sheep SpongeBob, SpongeBob Squarepants Boots the Monkey, Dora the Explorer Ziggy, Lazy Town Igglepiggle, In the Night Garden Dora Marquez, Dora the Explorer Wile E Coyote, Looney Tunes Patrick Star, SpongeBob Squarepants Scoop, Bob the Builder
