How Your Gut And Your Brain Communicate
I used to think how I felt during the day was just chance. Some mornings I woke up feeling light and clear-headed. Other mornings I felt heavy and sluggish before I had even left the house. It took me a while to notice a pattern: it wasn’t really chance at all. It was food.
Think about your own day. What did you eat this morning? How did you feel an hour later?
I started paying attention to the different kinds of food I was eating. Some of it was fibre — foods like beans, vegetables and wholegrain bread. Some was fermented (made using bacteria or yeast) food, like yoghurt. Some was pure sugar — cake, sweets, sugary drinks. Some was processed (made in a factory, with many ingredients) food, like fast food and packaged snacks. And some of it was just my everyday food — rice, pasta, the things I eat most days without thinking much about them.
When I ate fibre, I usually felt light. When I ate fermented food, I felt surprisingly clear-headed. Sugar gave me a short burst of energy, but processed food often left me feeling heavy for hours afterwards. It was strange how consistent it was.
Here is the part that really surprised me. Your gut and your brain are physically connected — by a nerve. It is called the vagus nerve (a long nerve that connects your gut to your brain), and it carries signals between the two, constantly. Not just occasionally. Constantly.
Your gut is talking to your brain all the time, about what you eat and how you feel. When you feel “sluggish” after a heavy meal, or strangely “clear-headed” after a light one, that is not just in your head. It is a real, physical signal, travelling along a real nerve, from your gut to your brain.
I don’t think most people picture their gut as something that talks. We think of the brain as the only one doing the thinking. But research shows the gut sends far more signals up to the brain than the brain sends back down. It is less like an assistant, and more like an equal partner in a conversation — one that happens quietly, below the surface of anything you consciously notice.
Once I understood this, I started to look at my own habits differently. I probably eat more sugar than I should, especially in the afternoon, when I’m tired and looking for something quick. I notice I often reach for processed food when I’m stressed, not because I am hungry, but because it is fast and easy. Neither of those choices is wrong, exactly — but now I understand why my gut might be telling my brain something afterwards.
It also changed how I think about small, everyday decisions. Choosing rice over fast food for dinner doesn’t feel like a big moment. But if my gut really is sending a signal to my brain every time I eat, then every one of those small, ordinary choices is a message, whether I notice it or not. I don’t think that means every meal has to be perfect. I just think it means the connection is real, even on the days when I’m not really paying attention to it.
Imagine what your gut is telling your brain about the food you eat, today and every day. It might be worth listening.
Reflect
Have you ever noticed a connection between what you eat and how you feel afterwards?
Which food category — fibre, fermented food, sugar, processed food, or everyday food — do you eat most often?
What do you probably eat more of than you should? Why do you think that is?Did you know your gut and your brain were connected before reading this? What do you think about it now?
