Using cartoon characters to promote unhealthy food is encouraging kids to eat it, according to campaigners.
They want there to be a crackdown on this to stop children tucking into stuff that is high in fat and sugar.
We want to know if advertising tempts you into buying certain things?
Would you be more likely to snack on something if your fave cartoon character was on the packaging?
Or do you just not eat certain things because you know what's bad for you?

"People should start to put well-known characters on good foods like apples. I eat food that tastes really good like burgers, but I also eat healthy things."
Alison, 11, Swindon, England
"I don't think ads or even cartoons make me want to buy junk food. It's all really down to the taste."
Sarah, 12, Atherton, England
"I eat what I like, nothing influences me to eat or stop eating food."
Sarah, 11, Barnsley, England
"Cartoons are unlikely to influence kids to eat either healthily or unhealthily, it is the taste that influences that - however what they do influence is kids' choice of one brand over another."
Robert, 13, Edinburgh, Scotland
"I wouldn't buy them, but younger children would tempted!"
Lauren, 10, Edinburgh, Scotland
"I think that it depends on what age you are, for younger children cartoon characters and free gifts seem to encourage you to eat unhealthy food, but when you are older it is normally based on the taste of things."
Beatrice, 13, London, England
"No way! Just because it has a cartoon character on, it doesn't want to make me buy it!"
Leona, 10, Chesterfield, England
"I think that cartoons do influence kids. But if some children are so gullible, it would be a brilliant idea to print them on healthy food packs so that children learn to eat more healthy foods."
Sasha, 11, Redbridge, England
"No, I wouldn't buy food with my favourite cartoon on the packaging but I think younger kids may be tempted by them!"
Belinda, 11, Leeds, England
"It may influence younger children but older children should know better!"
Hannah, 11, Colchester, England
"Parents should be responsible for choosing the foods they are purchasing rather than leaving it to the things their children want because it has their favourite cartoon on it."
Lauren, 12, Manchester, England
"I think they should use cartoon characters to promote healthy foods and to show kids what will happen to them in the future if they keep on eating unhealthily."
Siwan, 11, Cardiff, Wales
"Cartoons on unhealthy food packaging doesn't make me eat anything different to what I usually eat. But I think that it's really bad if it does persuade younger children to, as they need to learn how to eat more healthily and not to choose fatty foods because of their packaging."
Melissa, 13, Grange-over-Sands, England
"A cartoon character would not influence me to buy a food product. If I didn't like something, then I wouldn't buy it."
Alice, 13, Luton, England
"Adverts for unhealthy food should be banned because it is a bad influence on kids if they just sit and watch adverts with burgers. However, if they advertise ice-cream or chocolate, it usually makes me feel hungry!"
Lizzie, 11, Solihull, England
"I don't eat unhealthy things because they're on telly - I eat them because they taste so good!"
Bethany, 13, Crewkerne, England
"It doesn't really influence me, but my sister wants anything with characters from the latest movies on it."
Jack, 12, Pembrokeshire, England
"I do not think that the picture on the cover of the cereal really means if it's good for you or not. Normally I look at the back or side to check if it is unhealthy!"
Ronald, 9, Southfields, England
"Instead of promoting unhealthy foods with cartoon characters, why don't the Government promote healthy foods with cartoons. That way if kids are influenced by cartoons they would eat the healthy things instead."
Emily, 13, England
"Adverts wouldn't be the same without the catchy slogans and fun cartoon characters. I don't buy things just because a cartoon character is on the box or packet - I buy them because they're nice!"
Shannon, 12, Newcastle, England
"I think they should use cartoons to advertise healthy food only!"
Alex, 10, Hartlepool, England
"Adverts only influence what I eat when they make the food look really tasty and scrumptious, but I don't get tempted to eat food if there are characters on the packaging, that doesn't make a difference to me."
Lamin, 11, Birmingham, England
"I'm not influenced by what happens in cartoons or advertisements but some other children might be. I think all food that is shown in cartoons should be healthy!"
Megan, 11, Lincoln, England
"Just because they're my fave TV person and they're advertising a food, doesn't mean that I'm going to go ahead and eat it."
Sarah, 13, Portsmouth, England
"I don't care what advertises food - if I like the look of it, and it's not too unhealthy, I'll give it a try. It doesn't matter to me what's on the packaging. I'd rather take low fat, healthy crisps than ones with a familiar cartoon person on that's full of unhealthy ingredients. But I think people should stop butting into what we eat. It's our lives, so leave us alone to choose which path to take, because it's a skill we'll need when we're older."
Maddey, 13, Barmouth, Wales
"Everyone wants kids to eat healthy but when you see the adverts it's tempting to buy all the things that they show. So what do kids do? They buy the food on the adverts."
Sonu, 10, Bolton, England
"I hate it when people eat unhealthy foods because of what they see on the telly. I think that if food should be advertised on TV at all, then 50% of it should at least be healthy stuff!"
Grace, 11, Berkshire, England
"It doesn't make any difference to me seeing cartoon characters on unhealthy food. I'm not influenced by TV."
Emily, 12, Norfolk, England
"Sometimes they do. If I see someone eating ice cream, I usually go and get some out of the fridge!"
Yusef, 12, Aylesbury, England
