Cow & Gate is to stop producing a range of biscuits for babies after it emerged the products contained ingredients linked to heart disease.
The company will discontinue the Baby Balance Bear biscuits range, which was found to contain trans-fats.
Research by the Children's Food Campaign discovered that some baby foods were crammed with more saturated fat and sugar than chocolate biscuits and cheeseburgers.
The survey of 100 children's products found that 100g of Farley's Original Rusks contained more sugar (29g) than the same weight of McVitie's Chocolate Digestives (27.3g).
Heinz Toddler's Own Mini Cheese Biscuits contained 7.3g of saturated fat per 100g, more than the 6.7g found in a piece of McDonald's quarter pounder burger with cheese of the same weight.
And Cow & Gate's Baby Balance Bear Biscuits were did not refer to trans fats in their labels.
CFC described the findings as "staggering".
Joint co-ordinator Christine Haigh said: "The results of this survey are staggering. Many foods marketed for babies and young children are advertised as 'healthy'.
"In reality, in terms of sugar and saturated fat content, some are worse than junk food.
"In particular, failing to correctly label products that contain dangerous trans fats is outrageous."
Cow & Gate said it was acting after being made aware of the presence of a "small amount" of trans fats.
The CFC said one in nine Cow & Gate products tested were high in sugars (more than 15%).
The Cow & Gate spokeswoman added: "Of our baby foods tested by Sustain, only four had sugar levels above 15%. Three of these are biscuits, which require sugar in the recipe and contain 18% total sugars. This is less than most comparable adult varieties and other baby biscuits."
