To actually achieve children's interest in growing veg I needed to find out what veg they actually like most and can focus on them.

I found this survey done on the internet which is very helpful:

Apples, spuds and roast dinners top of the class with children, new survey reveals

03/09/2004

Roast dinners, apples and spuds come out on top as the firm favourites with children when it comes to what they like to eat, with curries, sprouts and pineapples at the bottom of the pile, according to a new survey released today by The Stroke Association.

The Stroke Association conducted a survey of children aged 4 to 16 years old to understand what foods they polished off their plates, how often, and what they pushed to one side. The survey sampled over 900 children across England and Wales over eight weeks.

The survey was conducted as part of The Stroke Association's forthcoming Stroke Awareness Week, which runs from 4th-10th October 2004. This year's theme is 'Eat a Rainbow-Beat a Stroke' and is particularly aimed at children aged 4-11 years old. Eating at least five portions of fruit and vegetables a day has been shown to reduce a person's risk of stroke by a third. Stroke Awareness Week aims to help children understand the benefits of eating a colourful diet full of fruit and vegetables and gives them the tools to do it.
