Healthy Pregnant Women
Conditions
Brief summary
The aim of the study is to compare the effects of conventional Ultra High Temperature (UHT) milk containing both A1 and A2 type β-caseins (CON) with a2 UHT Milk containing A2 type β-casein only (A1PF) on inflammation, tolerance, and GI symptoms in pregnant women as well as infants' birth outcomes from 12 weeks' gestation up to 40 days post-birth.
Interventions
Pregnant women in this arm will drink a2 UHT Milk twice a day, 200ml each time, until study completion. Their infants will be fed with the mother's breastmilk exclusively.
