Effect of Protein From Complementary Foods on Infant Growth, Body Composition and Gut Health
Study Details
Study Description
Brief Summary
Current research shows that dairy protein accelerates infant weight gain, which is a risk factor for later on obesity and metabolic syndrome. However, dietary protein from other sources haven't been studied yet. This longitudinal study will compare two complementary feeding regimens with dietary protein mainly from 1) meat; 2) dairy on infant growth, body composition and gut microbiome from 5 to 12 months of age in formula fed infants. Healthy infants at approximately 5 months of age will be randomized to either a meat protein, or a dairy protein group with complementary protein mainly from meat or dairy. Infants will consume one of these diets for 7 months (6-12 months of age) and infant growth, body composition, growth biomarkers and gut microbiome will be measured to compare between groups and over time.

Outcome Measures
Primary Outcome Measures
- Change of linear growth [6 months]
growth, including linear growth (length), body weight, and all the Z scores will be recorded at the beginning and end of the study.
Secondary Outcome Measures
- Change in Body composition [5 and 12 months of age]
body composition: fat mass, fat-free mass will be assessed at the beginning and end of the study
Other Outcome Measures
- Change in gut microbiome [5, 9.5 and 12 months of age]
Gut microbiota profile will be measured at the beginning, mid point, and end of the intervention by collecting stool samples
