Most people have blamed last night’s dinner at some point. Perhaps the lentil soup. Or the garlic bread they shouldn’t have had. And in certain cases, that conclusion makes perfect sense. However, bloating isn’t the occasional penalty for overindulging for a sizable portion of people—possibly as many as 30% of adults, according to various studies. It’s simply there all the time. Each morning. Following each meal. Sometimes it seems like there’s no reason at all. And that’s where the interesting part of the real story begins.
The conventional wisdom around bloating tends to orbit food. Cut out dairy. Avoid beans. Put down the carbonated beverages. That advice can really be helpful, so there’s nothing wrong with it, but it frequently ignores the bigger picture. An increasing number of gastroenterologists and nutritionists are now pointing to the nervous system, which is much more commonplace and, in a sense, much more treatable. In particular, how the body’s threat response and stress actively prevent digestion in ways that most people never associate with that tight, swollen feeling in their stomach.
Your body is technically still in a mild state of alert when you eat in a hurry, which, to be honest, describes most working lunches, or when you sit down to eat while still mentally processing a challenging conversation you just had. The stress hormone cortisol is increased. When the body believes it must be prepared for action, the digestive system slows down, which isn’t exactly its top priority. According to Natasha Draycott, Lead Nutritionist at Rheal Superfoods, the body puts survival ahead of digestion when we’re under stress. It sounds almost too simple to be true, but the downstream effects are real — slower gastric emptying, increased gut inflammation, and yes, bloating.
Because the gap between cause and effect seems too great, most people may never have noticed that connection. Instead of feeling bloated after a stressful event, you feel bloated after eating. However, the timeline is deceptive. Even before the food arrived, the digestive environment was already compromised.
Another issue is how people eat, which turns out to be nearly as important as what they eat. Eating quickly, which is practically the default in modern life, entails swallowing a lot more air, not chewing food into small enough pieces for the stomach to process effectively, and frequently consuming more than the body actually needs before satiety signals have had a chance to catch up. Each of those factors compounds. Furthermore, none of them deal with food sensitivity or intolerance in a clinical sense. They’re just physics and biology reacting to pace.
To be clear, FODMAPs are still important. For people with IBS or general gut sensitivity, fermentable carbohydrates — found in wheat, garlic, onions, apples, and certain dairy products — can trigger significant discomfort. Research consistently shows that a low-FODMAP elimination approach helps roughly three in four IBS sufferers. But the people who see the most dramatic improvement are often the ones who address behaviour alongside diet: slowing down at mealtimes, managing stress before eating, drinking water steadily through the day rather than gulping it with food.
Watching people chase elaborate supplement routines or elimination diets while still eating at their desks in ten minutes flat, it’s hard not to wonder whether the problem was ever really about the food at all. Sometimes the gut isn’t reacting to what’s in the meal. It is responding to the circumstances surrounding the delivery of the meal. Deep breathing and a slower fork don’t sell, so it’s not a very commercially viable solution, but the evidence keeps suggesting otherwise.
