One in 10 parents actually believe Jaffa cakes count towards fruit and vegetable portions, according to a shocking new survey.
Many parents believe snacks such as Jaffa cakes count as part of the five-a-day
But one in 20 do not know real oranges count as part of the five-a-day, the poll revealed.
Cola, spaghetti hoops and fruit-flavoured sweets are also mistakenly believed to contribute to the government guideline for fruit and vegetables.
Only a fifth of children reached the five-a-day standard every day.
Five percent eat none at all, their parents admitted in the survey for Green Giant.
Nutritionist Amanda Ursell told Sky News Online the results are "really shocking" and blames food companies for implying snacks and fruit drinks are healthier than they are.
"My advice to parents would be anything fresh, canned or frozen counts but anything that just contains fruit, like an apple pie, doesn't," she said.
