We're sure we don't need to tell you that this isn't the case, but we were suprised just how many parents who participated in the research believed that what is actually quite an indulgent snack could be a healthy choice.
Sadly for carb-lovers, regular white potatoes don't count towards your quota in any form. You might think it's obvious, but 23% of parents questioned thought a jacket potato was one of your 5-a-day, and 14% counted mash too!
Another worrying finding showed that 11% think vitamin supplements count as 5-a-day supplements, and 1 in 10 parents didn't think that eating fruit was healthy - an opinion that is likely to stem from the recent rise in awareness of the dangers of sugar in large quantities.
Fruit, funnily enough, does count towards your 5-a-day, although it is better to have a variety of fruits and vegetables rather than fruit alone.
84% of the parents did, however, say that they were concerned about their child's diet, showing that they had an awareness of the importance of 5-a-day, despite sometimes struggling to identify it.
