Diet Intervention for Pregnancy Microbiome
(MOMS Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how different diets impact the variety of gut bacteria in pregnant women and how these changes might affect their babies. Participants will either eat more fermented foods, increase fiber intake, or do both, while some will maintain their usual diet. The goal is to determine how these dietary changes can influence health during pregnancy and after birth. Women in the early stages of a single pregnancy who are generally healthy are the best fit for this trial. As an unphased trial, this study offers participants the opportunity to contribute to valuable research that could enhance maternal and infant health.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, if you are taking weight loss medications, regular high dose aspirin, or regular prescription opiate pain medication, you may not be eligible to participate. Additionally, if you have taken certain medications like antibiotics or corticosteroids in the past two months, you may also be excluded.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
A previous study found that fermented foods like yogurt and miso soup are well-tolerated by pregnant women and may even lower the risk of early birth. However, some research suggests improper fermentation can affect gut bacteria. Overall, fermented foods are generally considered safe.
Regarding fiber, studies have shown that a high-fiber diet is safe and can increase the variety of beneficial gut bacteria, which is important for both mothers and babies. There are no major safety concerns with consuming more fiber during pregnancy.
Combining fiber and fermented foods appears promising, but limited data exist on their combined safety. However, both are usually safe individually and are thought to improve gut health together.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments because they harness the natural power of diet to potentially improve pregnancy health, focusing specifically on the microbiome. Unlike standard prenatal care, which often involves supplements and medications, these treatments use fermented foods and fiber to naturally influence gut health. Fermented foods introduce beneficial probiotics, while increased fiber intake supports digestive health and regularity. By combining these dietary elements, researchers hope to uncover a simple, food-based strategy that could enhance maternal and fetal health during pregnancy.
What evidence suggests that this trial's dietary interventions could be effective for microbiota diversity in pregnancy?
This trial will compare different dietary interventions during pregnancy. Research has shown that eating fermented foods, which participants in one arm of this trial will consume, can increase the variety of beneficial bacteria in the body and strengthen the immune system. These foods help develop a healthy gut in both mothers and their babies. Another arm of this trial will focus on increasing dietary fiber intake, which links to positive changes in gut bacteria and better overall health during pregnancy. Observational studies suggest that combining fermented foods and fiber, as tested in another arm of this trial, might enhance these benefits, supporting the health of both mother and baby. These dietary changes might help reduce risks like pre-term birth and improve long-term health outcomes.12678

Are You a Good Fit for This Trial?
This trial is for healthy pregnant women over 18, in their first trimester up to 22 weeks. Participants must be carrying a single baby and able to give samples of blood, stool, vaginal swab, and breast milk. They cannot join if they have severe obesity, high blood pressure, certain diseases (like autoimmune or liver disease), recent GI surgery (except gallbladder or appendix removal), or are immunocompromised.Inclusion Criteria
