Did you know that many ingredients in ultra-processed foods have been shown in research to interfere with the gut’s mucus layer and change how your microbes behave?

The challenge is that our microbiome has evolved over millions of years…and is now exposed to ingredients it has never encountered before.

In this episode of Healthy Gut, Healthy Kids, we’re joined by Alanna Collen, PhD to explore how modern diets and lifestyles are reshaping our inner ecosystem — and what that means for our children’s long-term health.

We cover:
🦠 how modern food impacts the microbiome�🛡️ the gut barrier & why it matters�👶 why early life is a critical window�💊 how antibiotics shape gut health�🌱 what actually supports a healthy microbiome

Understanding the microbiome gives parents powerful tools — in a world that’s changing faster than our biology.

Did you know that a baby’s gut microbes help train their immune system — teaching the body what to react to, what to tolerate, and how strongly it should react?
But modern life is changing those microbes fast.
C-sections, antibiotics, formula feeding, and ultra-processed food additives are all shaping the early-life microbiome — during the most critical window for immune development.

In this episode of Healthy Gut, Healthy Kids, we’re joined by Alanna Collen, biologist, science writer and author of 10% Human, to unpack how modern life is reshaping our inner ecosystem — and what this means for children’s long-term health.

We talk about:�🦠 why humans are ecosystems�🛡️ how gut microbes protect the gut barrier�🔥 how the microbiome influences inflammation�👶 why infancy is a critical window�🍼 the role of birth, breastfeeding & bifidobacteria�💊 how antibiotics and C-sections shift microbial development�🌱 why fiber diversity is one of the most powerful tools for gut health

You don’t need perfection — but understanding the microbiome gives parents powerful knowledge in a world that’s changed faster than our biology has.

Did you know that your diet before you’re even pregnant may shape your child’s health for decades to come?

Fertility rates are falling worldwide — and growing evidence suggests that nutrition, stress, lifestyle, and the gut microbiome may play a far bigger role in fertility, pregnancy outcomes, and a child’s long-term health than most people realise.

In this episode, we’re joined by Dr. Federica Amati — Head Nutritionist at ZOE, researcher at Imperial College London, and Sunday Times bestselling author — to unpack what the science actually says about fertility, pregnancy, and the first 1,000 days of life.

We cover:
– why fertility rates are declining and how nutrition plays a role
– which diet best supports fertility, pregnancy, and your baby’s health
– the key ways to optimise the body for pregnancy
– how a mother’s gut microbiome helps shape her baby’s immune system
– and how early nutrition is linked to risks like obesity, type 2 diabetes, and even cancer later in life
Whether you’re trying to conceive, pregnant, or simply curious about how early biology shapes lifelong health, this conversation offers clear, evidence-based insights to help you feel informed — not overwhelmed.
