Some of the world's leading medical experts have said that Ronald McDonald and Happy Meals must be axed to save youngsters' health.
Five hundred and fifty docs have sent an open letter to McDonalds' to tell them they are fuelling obesity, and that Happy Meals get children hooked on junk food.
The campaign group Corporate Accountability International took out full-page adverts in US newspapers with the letter, which was addressed to the firm's HQ.
The letter read: 'Marketing can no longer be ignored as a significant part of this huge problem'. It then went on to implore McDonald's to stop aiming their high fat, high salt and high sugar foods to children.
McDonald's hit back saying it was committed to 'responsible advertising' and that Ronald would never be removed from the branding:
'Ronald McDonald has never left McDonald's. He has been our mascot for 35 years. We serve high quality food. Our Happy Meals offer choice and variety in portions for kids.'
What do you think? Personally, I've always found Ronald a bit on the sinister side.
How often would you take your kids to McDonalds - never, once a week, a month, occasionally?
