The American Heart Association makes every effort to avoid any actual or potential conflicts of interest that may arise as a result of an outside
relationship or a personal, professional, or business interest of a member of the writing panel. Specifically, all members of the writing group are

ABSTRACT
Since the American Heart Association last presented nutrition guidelines for
children, significant changes have occurred in the prevalence of cardiovascular risk
factors and nutrition behaviors in children. Overweight has increased, whereas
saturated fat and cholesterol intake have decreased, at least as percentage of total
caloric intake. Better understanding of children’s cardiovascular risk status and                                                                       www.pediatrics.org/cgi/doi/10.1542/

improved self-regulation may better withstand the cur-
rent food-surplus environment.111 The second potential
benefit relates to taste preference.112–116 Both amniotic
fluid and breast milk provide flavor exposure to the fetus
and infant. These exposures influence taste preference
and food choices after weaning. Thus, exposure to
healthier foods through maternal food consumption
during pregnancy and lactation may improve acceptance
of healthy foods after weaning. Because infant responses
to taste are different from mature taste, these early ex-
posures may be critical in determining food preference
later in life.
   A critical social problem for mothers interested in
breastfeeding in the United States is the lack of a tolerant
social structure.117 Breastfeeding rates decline rapidly be-

Daniels, MD, PhD, Matthew W. Gilman, MD, Alice H. Lichtenstein, DSc, Karyl Thomas Rattay, MD, Julia Steinberger, MD, Nicolas Stettler, MD, Linda Van Horn, PhD, RD The American Heart Association makes every effort to avoid any actual or potential conflicts of interest that may arise as a result of an outside relationship or a personal, professional, or business interest of a member of the writing panel. Specifically, all members of the writing group are required to complete and submit a Disclosure Questionnaire showing all such relationships that might be perceived as real or potential conflicts of interest. A summary of all such reported relationships can be found at the end of this document. ABSTRACT Since the American Heart Association last presented nutrition guidelines for children, significant changes have occurred in the prevalence of cardiovascular risk factors and nutrition behaviors in children.

These exposures influence taste preference and food choices after weaning. Thus, exposure to healthier foods through maternal food consumption during pregnancy and lactation may improve acceptance of healthy foods after weaning. Because infant responses to taste are different from mature taste, these early ex- posures may be critical in determining food preference later in life. A critical social problem for mothers interested in breastfeeding in the United States is the lack of a tolerant social structure.117 Breastfeeding rates decline rapidly be- tween 2 and 3 months, which is when many mothers return to work or school.118,119 Full-time employment is FIGURE 2 consistently associated with shorter periods of breast- Dramatic change in food sources during the first 2 years of life.
