Investigating the Detection of Bovine and Soy Proteins in Human Milk

This study is a randomized, cross-over, dietary intervention research design comprising a 5-day run-in period, two 3-day dietary interventions, and a 2-day washout period. Participants (mother-offspring dyads) will be randomly assigned to order of interventions. Participants will be recruited as a convenience sample from mother-offspring dyads in the greater Moscow, Idaho and Boise, Idaho areas. The initial purpose of this study is to to learn more about the use of an allergen test strip to detect cow's milk and soy food allergen proteins in human milk, to identify soy and bovine-derived peptides in human milk after consumption of these foods, to explore the impact of maternal bovine milk and soy milk consumption on human milk and maternal/infant gastrointestinal microbiomes and to examine maternal stress during periods of dietary elimination and re-introductions periods.
