Healthy children aged between 4 and 13 years.
Children and early teens have been selected as parent-led dietary change is appropriate across this age group (detailed below). Additionally this age group is an appropriate target for substitution, rather than ‘eat more’ dairy food message.

- Primary Outcome Measures
Name Time Method Change in children's intake of total and saturated fat from dairy foods. Children's intake will be measured on three occassions (weeks 0,12,24) using multiple (3 days) 24 hour recalls at each occasion. The multiple pass 24 hour recall method will be conducted by a dietitian in person (day 1) and then by phone (day 2 and 3).[Weeks 0, 12 and 24];Change in overall dietary intake (food choices, energy and nutrient intake, diet quality).Children's intake will be measured on three occassions (weeks 0,12,24) using multiple (3 days) 24 hour recalls at each occasion. The multiple pass 24 hour recall method will be conducted by a dietitian in person (day 1) and then by phone (day 2 and 3). <br>The rigorous method used to collect dietary intake will allow nutrient intakes to be estimated. Diet quality will be assessed using a validated index.[Weeks 0, 12 and 24]
- Secondary Outcome Measures
Name Time Method Compliance to intervention measured by a change in pentadecanoic acid as a biomarker for dairy fat intake; degree of change in dairy food choices using the pantry inventory and dietary recall; exploring the facilitators and barriers to intervention compliance (parental, child and intervention factors).[Weeks 0, 12 and 24];The degree of dietary change (full, partial, or nil) from regular fat dairy foods to reduced/low-fat varieties will be associated with the degree of overall dietary change.<br>Dietary change will be detiremined using the 24 hour recall data and verified using nutrient (saturated fat) and biomarker (pentadecanoic acid) data. Full change will reflect children consuming only reduced-low dairy fat products, nil change children consuming only regular fat dairy products and partial change will be a mixed of both full and low fat products.[12 and 24 weeks]
