Martina Watts rightly draws urgent attention to the deficiencies of modern diets on the one hand and artificial additives on the other, essential knowledge for all parents concerned with the quality of food their children eat.

My young children, would not eat some of the healthy food I hoped they would get used to before they went to school, where they discovered all the rubbish other children were allowed.

It was only much later they came to realise what was best for them.

For parents, it is a constant struggle to know whether to insist and fight or whether it may do less harm to let them get on with it. It certainly is less of a battle.

Martina rightly points out the responsibility of governments and advertisers.
