  Purpose

The goals of the proposed research are to specify the timing and consequences of the sensitive period for flavor learning in infants who are being breastfed or formula fed. The investigators will conduct a randomized within- and between-subject study of women and their infants during a 15-month window.


Condition Intervention
Focus of the Study is to Determine Whether There Are Sensitive Periods of Flavor Learning in Humans
Other: Timing of Diet and Flavor Experience

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator)
Official Title: Sensitive Periods in Human Flavor Learning

Primary Outcome Measures:
  • Food and flavor acceptance [ Time Frame: Once a month from ages 2 weeks - 15 months ] [ Designated as safety issue: No ]
    Psychophysical testing conducted on dyad to determine sensitivity and preference for a variety of food flavors.

  • Growth [ Time Frame: Once a month from ages 2 weeks - 15 months ] [ Designated as safety issue: No ]
    Infants and mothers will be weighed and measured and stool and urine samples will be collected for later analysis of biomarkers of growth.


Secondary Outcome Measures:
  • Maternal perception [ Time Frame: Once a month from ages 2 weeks - 15 months ] [ Designated as safety issue: No ]
    Mothers will complete a variety of standardized questionnaires to assess infant temperament, growth and behavior.

  • Genotype [ Time Frame: Once a month from ages 2 weeks - 15 months ] [ Designated as safety issue: No ]
    Saliva will be collected for subsequent determination of obesity- and taste-related genes

Arms Assigned Interventions
Experimental: 1M0.5

Mothers will receive the intervention for 1 month beginning when their infant is 0.5 months old.

Intervention: Timing of Diet and Flavor Experience

Other: Timing of Diet and Flavor Experience
Groups differ in the timing and duration of exposure to flavored food experience.
Experimental: 1M1.5

Mothers will receive the intervention for 1 month beginning when their infant is 1.5 months old.

Intervention: Timing of Diet and Flavor Experience

Other: Timing of Diet and Flavor Experience
Groups differ in the timing and duration of exposure to flavored food experience.
Experimental: 3M0.5

Mothers will receive the intervention for 3 months beginning when their infant is 0.5 months old.

Intervention: Timing of Diet and Flavor Experience

Other: Timing of Diet and Flavor Experience
Groups differ in the timing and duration of exposure to flavored food experience.
No Intervention: Control
Mothers will not receive the intervention.

Detailed Description:

This is a randomized clinical trial on both breastfeeding and formula feeding infants to determine the effects of the timing of flavor experiences on subsequent food acceptance in both members of the dyad.
