Brief summary

The home and family food environment are among the most influential factors in shaping children’s dietary habits.

During the telephone calls participants will receive information about the basics of a healthy diet and children’s dietary recommendations, be encouraged to make fruit and vegetables readily available and accessible, eat meals as a family and without the television on, and to identify and reduce stimuli for unhealthy eating. Furthermore the telephone calls will encourage parents to role model fruit and vegetable consumption and utilise positive parenting strategies related to child feeding. The telephone support calls will also be facilitated by print workbook
