What role do gut microbes play in our health?
Hello and welcome to Zoe Recap, where each week we find the best bits from one of our podcast episodes to help you improve your health. Inside each of us lives a bustling community of microbes, tiny organisms that outnumber our human cells. They're there from the very moment we're born, shaping our immune system and influencing our long-term health. The science of the microbiome is evolving rapidly, but one thing is clear. We need to take care of these microbes so that they can take care of us. Today, I'm joined by Dr. Suzanne Dipkota and Tim Spector to explore how our gut bacteria protect us from diseases and what we can do to strengthen this vital partnership.
The education of our immune system by a microbe starts from the moment we're born. Looking at the early life microbiome, the first year of life tells you a lot about the interactions with the immune system and the gut microbiome. There's... a lot of research now on this really critical window where a baby is born essentially sterile, no microbes, until they get the first bugs from their mother. And immune cells, as more bacteria start to colonize the gut, so do more immune cells start to develop in the intestines as well. And what's really interesting is there's this weaning period, weaning meaning when you go from breast or formula on to your native diet or table foods or adult diet. And that introduction of food, you had this rapid expansion of immune cells in the infant.
And a lot of that is attributed to the more diverse foods you eat, the more diverse microbes that colonize the gut. And so there's this beautiful evolutionary conserved interplay between microbes colonizing immune cells growing, which you want. That's a good thing. You want diverse immune cells so that when you grow up and see different foods, as Tim said, and different life exposures, you don't react and auto-react. And so there's a lot of studies saying, okay, what happens when we mess that up and we give babies a lot of antibiotics early in life or something like that? And studies show that their immune system doesn't develop as well as their microbes don't also. And the hypothesis being, could that be predisposing infants, children to autoimmune conditions, airway allergies, food allergies, and so on?
So I think we study a lot what happens in adults, the defects that happen in adults, but a lot of it starts very early in life.
That's probably why we've got so many allergies now that we didn't have 40, 50 years ago because breastfeeding rates have gone down and diversity of baby foods has gone right down. They're now getting ultra processed foods very early on in life. And you combine that with cesarean sections. Right. plus antibiotics, it's a recipe for all these allergies we're getting, isn't it? Because as you said, a badly trained immune system that our ancestors didn't have. They had the perfect system to train it.
I'm always conscious when we listen to this, you know, having two children of my own that it's really hard to, you know, go through pregnancy, have a baby, get through this. And that often this podcast always feel like, and here there's yet more ways in which as a parent and often particularly as a mother, you feel like you're failing. So I always want to feel like, I think this is a hard, you know, it can feel hard and lots of people are trying really hard to do their best. One of the things that I'm really struck by is how much on this podcast in the last year, we've been talking about ultra processed food and much more so than when we first started sort of Zoe eight years ago. And thinking about like my own experience with my youngest one, the extent to which we're all sort of pushed towards these sort of pre-packaged foods that say they're super healthy and have all these organic ingredients.
But basically you're giving them mush out of a packet and there's only about four types of mush. And I think Suzanne, you're telling me you really want to be giving your children a lot of different foods because that's what's needed to give them a lot of different bacteria.
