It's Not Just Food: How Stress Sabotages Gut Health (And What You Can Do About It)
It’s Not Just Food: How Stress Sabotages Gut Health
(and What to Do About It)
By Sarah Cox
As a gut health nutritionist, I spend a lot of time talking to people about their digestive issues—everything from reflux and bloating to erratic toilet habits, bowel urgency, and even conditions like diverticulitis, ulcerative colitis, or gallbladder removal.
When people come to me, they’re searching for solutions. Their first instinct? Blame the food. They’re convinced that if they can just pinpoint that one "trigger" food and eliminate it, their symptoms will disappear.
The problem? It’s not that simple.
Why Food Isn’t the Whole Story
Trying to identify a single food as the culprit behind ongoing digestive issues is like trying to fix a leaky boat by plugging just one hole—when there are several. Yes, food plays a role, but it’s only one piece of the puzzle; and often when you work on the underlying causes, food becomes less of an issue.
This hyper-focus on food can actually create more problems. People start fearing food, avoiding meals they once enjoyed, and restricting their diets to a handful of “safe” foods. Over time, this leads to nutrient deficiencies, frustration, and a sense of being trapped in an endless cycle of elimination.
And the worst part? Even after cutting out certain foods, symptoms often persist. That’s because digestion isn’t just about what you eat—it’s about how your body processes food. And one of the biggest disruptors of digestion is stress.
Digestion Starts in the Brain
Believe it or not, digestion begins before you take your first bite. About 20–30 minutes before eating, your body enters the cephalic phase of digestion. This is when you start thinking about food—when you smell, see, or anticipate a meal.
Ever noticed how your mouth waters when you smell your favourite dish cooking? That’s your body preparing for digestion by releasing saliva, which contains digestive enzymes. Your stomach then produces acid, and your gallbladder gets ready to release bile to help break down fats.
But here’s the catch: stress can completely shut this process down.
When you're stressed, your body shifts into fight-or-flight mode—the part of your nervous system designed for survival. In this state, digestion takes a back seat because your body is focused on dealing with perceived danger, not breaking down food.
If you’re constantly eating while stressed—whether that’s rushing through meals, eating at your desk, or multitasking—you’re skipping this essential phase of digestion. And when digestion doesn’t start properly, food sits in the stomach for longer, leading to bloating, discomfort, and poor nutrient absorption.
Simply put: you could eliminate every possible "trigger food," but if you're eating in a stressed state, your digestion will still suffer.
What Can You Do?
The good news? You can shift your body into a rest-and-digest state with simple, intentional habits. Here are five practical ways to support your digestion and reduce stress:
-
Make time for meals – Set aside time to cook and eat mindfully. Give your digestive system the chance to kick into gear before eating.
-
Practice deep breathing – A few deep breaths before meals can activate your parasympathetic nervous system (the "rest and digest" mode).
-
Incorporate relaxation techniques – Regular meditation, deep breathing, and relaxation exercises can lower overall stress levels, helping digestion function optimally.
-
Eat without distractions – Step away from your phone, laptop, or TV. Eating in a relaxed environment allows your body to focus on digestion.
-
Slow down your eating – Put your fork down between bites, chew your food thoroughly, and truly taste what you’re eating.
Incorporating relaxation techniques into your weekly schedule - Using Sensate to Support Your Gut-Brain Connection
One powerful way to reduce stress and improve digestion is through vagal nerve toning, which helps shift your body into a more relaxed state. The Sensate device is designed to do just that.
A recent study showed that using Sensate 5–6 times per week for three months led to:
-
Significant reductions in stress levels
-
Increased feelings of well-being
-
Reduced severity of overall symptoms
By integrating relaxation practices like Sensate into your routine, you’re not just calming your mind, you’re actively improving your digestion.
Final Thoughts
If you’ve been struggling with digestive issues and focusing only on food, it’s time to zoom out and look at the bigger picture. Stress, mindfulness, and your nervous system play just as big a role—if not bigger—than the food on your plate.
So next time you sit down for a meal, take a deep breath, slow down, and let your body do what it was designed to do.
