Gut Feeling: Your Body Knew Before You Did
Somewhere between 70 and 80 percent of your immune cells live in your gut.
Gut Feeling: Your Body Knew Before You Did
---
There is a woman I know in Valletta — runs a small ceramics studio off Merchants Street, eats well, moves well, sleeps reasonably well — who spent two years convinced she had anxiety. The tight chest, the low-grade fog, the mornings that never quite cleared. It took a functional medicine appointment in London to suggest that the problem might not be in her head at all. It might be thirty feet lower.
The gut microbiome is one of those subjects that sounds like trend science until you look at the research, and then it stops sounding like anything except urgent. Somewhere between 70 and 80 percent of your immune cells live in your gut. The roughly 100 trillion microorganisms in your digestive tract — bacteria, fungi, viruses, all of it — communicate directly with your brain via the vagus nerve, influencing mood, inflammation, and energy in ways we are only beginning to map properly. When that ecosystem is balanced, you notice mostly by the absence of symptoms: no bloating, no irregular digestion, no afternoon crashes that feel disproportionate to what you actually did. When it isn't balanced, the body finds creative ways to tell you.
The signs of a compromised microbiome are rarely dramatic. They tend to be the things you normalise over time — persistent fatigue that sleep doesn't fix, skin that reacts to nothing obvious, a digestion that is technically functional but never quite comfortable. What disrupts the balance is equally mundane: antibiotics taken without probiotic support, a diet heavy in ultra-processed foods, chronic stress, too little sleep. None of these feel like emergencies. That is precisely the problem.
What genuinely helps is less exciting than the supplement industry would like you to believe. Diversity of plant foods — ideally 30 different plant varieties across a week — feeds the widest range of beneficial bacteria. Fermented foods like yoghurt, kefir, kimchi, and real sourdough introduce live cultures directly. Probiotic supplements can be useful, particularly after antibiotics or during periods of high stress, though the strain specificity matters more than the brand name on the label.
Singapore taught me to eat fermented food at every meal without thinking about it. Malta is teaching me to slow down enough that the body can actually process the good you're giving it.
One thing you can do: Add one fermented food to your meals every day for the next two weeks — a spoonful of live yoghurt, a few forkfuls of sauerkraut, a glass of kefir. No supplements required. Just give your microbiome something to work with.
