WHOA Highest fat and sugar

SLOW Higher in fat and sugar, More processed foods

GO Lowest in fat, no added sugar, WG, V, F, lean meats

GO-SLOW-WHOA

• Nutritional recommendations for school-aged children are relatively well-established; less so for preschool children– Issues: sugary beverages, snacks, F & V, calcium

• Children do not consume adequate diets: what can we do to ensure this?– Behaviorally based nutrition education– Parenting practices– Environmental changes (marketing)

• New directions– Do we need ‘kid foods’?– How can we use natural biologic variations in appetite

to our advantage?– Decreasing food availability – periods of ‘not eating’

Final Thoughts

The test of the morality of a society is what it does for its children.
