Essentially our job as caregivers is to get them ready to be independent people in the world. But they are also so vulnerable throughout the course of growing up in terms of their safety in a variety of ways that they need to have those skills and build those skills in an ongoing way so that they can participate in keeping themselves safe. Hi, Kara.

Today's conversation is about something that is seemingly simple and maybe not science based at all, which is the phrase trust your gut or trust your gut instinct. But in fact it has profound layers beneath it that are physiologically based in science and have all sorts of reverberations out from that scientific and physiological basis, which is about teaching kids how to be healthy and safe. And we cover this topic in 18 different ways in our school based curriculum. Everywhere from our kindergarten lesson about safety and consent all the way up through high school, we are constantly referring back to instinct, gut. What is your body telling you? What are the cues? How do you understand your brain's relationship to your body? There's so much fascinating stuff to cover with these three little words, trust your gut. So, Cara, will you start out with actually the physiological basis of this phrase?

I will. I want to preempt that by just saying there's a reason we teach it year in and year out in our curriculum, which is that while these are very biological processes, they're also learned. This is complicated. Like we think about things that just happen automatically inside our body as being things that we don't actually have to learn how to do. But this trusting your gut is this funny combination of your body's going to do this thing automatically that you need to learn to cue into to like you need to listen, you need to actually trust it. We don't say trust your heart to beat, we don't say trust your lungs to breathe, but we have this phrase that you should trust your gut instinct because it's a reminder that that automated process is trying to yell at us. And as kids get older, Vanessa, and we'll get into this, sometimes you have to not trust your gut. Sometimes as you're going through the tween and teen years and the brain is mid development and maybe things are not super even in there and you're making high risk, high reward choices or feel good decisions, that gut instinct might not take you to the right place. Right. And so we'll get into that. But let's talk about the brain gut connection for a second where we did have some of this conversation with Elisa Song, my very dear friend from residency training, who is A pediatrician and functional medicine doctor up in Northern California. And she was on an episode and talked a lot about brain gut connection. But let's just do maybe a quick overview for people who like the science. So we'll start with the vagal nerve. The vagus nerve is the. I think it's the longest nerve in the body. Someone's going to correct me on that. It's very long, this nerve, and it is literally the primary conduit, nerve conduit between the gut and the brain. And what happens in the gut. This is so fascinating to me. I learned this in medical school when I was learning about celiac disease. So kids and adults who have celiac disease, when they ingest gluten, their gut becomes really, really inflamed. And instead of having these villi and microvilli, which are these, like little projections on projections on projections that increase the surface area of the gut, the inflammation kind of wipes all of this away, and your gut turns into this tube and it can't absorb anything particularly well, and the microbiome can't thrive particularly well. And one of the side effects is that serotonin, which is a neurotransmitter and is largely produced in the gut by the microbiome, serotonin levels fall because the gut cannot do what it's supposed to do. And this has been known for a very long time. One of the presenting signs of celiac disease can be depression because of low serotonin levels, but all has to do with inflammation in the gut. And so, you know, that is one kind of brain gut connection. And it's really. It's amazing. Like when I tell you 90% of your body serotonin is made in your gut, and that neurochemical then really feeds into the way your brain thinks and feels. It's remarkable. But that's slightly different from this gut instinct that we're talking about. We're not talking about the microbiome making neurotransmitters. What we're talking about is intuitive signals. What we're talking about is a neural network in the gut that processes information in real time and sends signals to your brain. So, Vanessa, you and I are. We jump on a zoom and. And we are both finishing going through our emails and we're about to start a meeting, and we both get the same email with bad news and what happens, or good news and what happens. We look at each other on the screen, our faces fall, we become pale, and we have horrible. It feels like a pit in our stomach. And that is sort of one of these feelings that we, I think have all experienced day in and day out of our gut telling us something is wrong and you literally, you feel sick to your stomach. Right?
