Most alarmingly, more than one in 10 parents don't believe eating fruit is healthy.
Although 84% of parents were concerned about their child's diet, one-in-three in the poll couldn't correctly identify what 'five-a-day' actually means, with only two-thirds of parents correctly identifying 'five pieces of fruit or vegetable.'
Researchers found nearly one-in-four mothers and fathers also wrongly think a jacket potato counts, and one-in-seven believe mashed potato is considered a portion of the 'five-a-day' recommended by health chiefs.
But no, potato doesn't count as part of the five-a-day allowance.
Other vegetables that don't count in the vegetable stakes are yams, cassava and plantain. They are also usually eaten as starchy foods. However, sweet potatoes, parsnips, swedes and turnips are vegetables that are usually eaten in addition to the starchy food part of the meal.
So, how about you? Do you get the recommended guidelines of five pieces of fruit and vegetables a day?
