Have you ever seen a headline claiming a certain food can boost your fertility and rolled your eyes? You're not wrong to be sceptical, and most of what circulates online about diet and conception is wellness noise dressed up as science.

This time, the science actually holds up. A new 2026 study traces a real, step by step mechanism from what's on your plate to whether an embryo implants.

In this episode of The Science of Motherhood, Dr Renee White breaks down a new mouse study linking dietary fibre, gut bacteria and the uterine immune system. She walks through how the pathway works, where the research falls short, and what's reasonable to take from it if you're trying to conceive.

You'll Hear About:

• Why mouse studies are used in fertility research
• What the new 2026 fibre study found
• How gut bacteria influence uterine immune tolerance
• Why this mechanism doesn't yet prove human benefit
• What foods support this specific fibre pathway

You don't need to overhaul your diet to take this seriously. Paying attention to fibre quality, not only quantity, is a small, evidence-backed step available to you now. The mechanism is real, even if the guarantee isn't, and that still counts for something.

You've sat through an antenatal appointment focused on blood pressure and bump measurements, wishing there'd been room to talk about how you were actually feeling. Midwives want that room too, working inside appointments measured in minutes. There's real momentum building to bring emotional wellbeing further into that time together.

Two researchers went looking at exactly what that momentum looks like in practice, and how to act on it without asking midwives to find time they don't have.

In this episode of The Science of Motherhood, Dr Renee White sits down with Lesley Pascuzzi, childbirth educator and perinatal mental health researcher, and her colleague Nicole Freeman, midwife and PhD researcher in early pregnancy care, to unpack what midwives told them about supporting mental health during pregnancy. Together they explore where the system falls short, and the pilot program already testing a different way forward.

You'll Hear About:

• Why the current model centres illness over wellness
• What midwives believe a well woman looks like
• How time pressure shapes mental health conversations
• Why continuity of care changes everything
• What the new pilot program is testing

Knowledge is the foundation of advocating for your own mental health, in pregnancy and beyond. The more you understand about your options, the more equipped you are to ask for exactly what you need.

If you've ever left an appointment feeling rushed or unheard, send this to a friend who's navigating pregnancy right now. And subscribe so you don't miss an episode of The Science of Motherhood.

Your parents or your in-laws are going to tell you they did things differently and you turned out fine, right in the middle of a conversation about sleep safety or feeding choices, and you can feel the eye roll building before they've even finished the sentence. Their love is real, and you don't have to brace for it each time they visit.

In this episode of The Science of Motherhood, Dr Renee White unpacks what grandparents and in-laws genuinely need to know before the baby arrives, cutting through outdated advice to share what the current evidence actually supports, what's changed, and what's genuinely worth doing differently.

You might be pregnant or newly postpartum and quietly dreading the moment a well-meaning relative tells you how it used to be done. If you're the grandparent listening in, most of those moments come down to a gap in information that's easy to close. Start the conversation early, and you give your village the chance to actually hold you up, the way you deserve.

You'll Hear About:

• Why vaccinations protect newborns before six weeks
• How updated safety guidance differs from old advice
• What matrescence means for the woman you love
• Why cuddles are something to be earned
• How to offer help without the unsolicited opinions

You don't have to manage anyone else's feelings while you're still learning your own baby. The right people in your life will meet you with curiosity instead of correction, and that's the kind of village worth building around yourself and your baby.

Share this with the grandparent, aunty, or friend who wants to support you well, and with the parent who needs the words to start this conversation early. And subscribe so you don't miss an episode of The Science of Motherhood.
