As any parent knows, getting children to eat what we want them to eat is a challenge, as is packing a healthy lunchbox that they'll actually eat. It's important to offer variety (many kids get bored easily, haven't you noticed?) as well as keeping meals high in protein, veg, fruit and fibre, and low in fat, salt and sugar. A child's lunch should provide at least a third of his or her daily nutritional requirements. Without a good midday meal youngsters struggle to concentrate in the afternoon.
