For many, bread is a breakfast staple, but wellness expert Dr Mickey Mehta has raised concerns about its potential effects on the body.
In a post shared on Instagram recently, he said, 'Can't do without bread every morning? Well… at least try to reduce. Because bread could be the most dangerous thing you put in your body.' His warning isn't just about processed ingredients or high-carb content — he points to a rare condition called auto-brewery syndrome, where the gut microbiome ferments carbohydrates, including those in bread, into ethanol. This can cause intoxication-like symptoms even without consuming alcohol.
While this condition is uncommon, it raises important questions about how certain foods interact with gut health. Dr Mehta suggests a simple remedy for those who continue eating bread: 'Have Isabgol (Psyllium Husk) at night and first thing in the morning.'
Auto-brewery syndrome is a rare condition where the body produces alcohol internally due to the fermentation of carbohydrates by an overgrowth of certain gut microbes, typically yeasts like Candida or specific bacteria. 'When the gut microbiome is disrupted — often after antibiotic use, a high-carbohydrate diet, or gastrointestinal disorders — fermentative organisms can proliferate,' explains Dr Adithya V. Naragund, senior consultant in GI & HPB Surgery at Cytecare Hospitals, Bengaluru. This imbalance leads to excessive ethanol production in the intestines, which gets absorbed into the bloodstream, causing symptoms of intoxication.
'Factors that increase the risk include a history of gut dysbiosis, diabetes, or other conditions that compromise the normal microbial balance, as well as diets high in refined carbohydrates,' mentions Dr Naragund.

For most people, moderate bread consumption — especially whole grain varieties — does not negatively impact gut health. However, excessive intake of refined bread, high in simple carbohydrates and low in fibre, can contribute to gut dysbiosis. 'This imbalance may promote the overgrowth of fermentative microorganisms, leading to bloating, gas, or low-grade inflammation,' says Dr Naragund. Those with metabolic or gastrointestinal issues may be more susceptible to adverse effects. On the other hand, fibre-rich breads can support gut health by nourishing beneficial bacteria and promoting digestion.
Psyllium husk, a soluble fibre, plays a crucial role in digestive health. 'It works by absorbing water and forming a gel-like substance, which not only softens stool and aids in regular bowel movements but also helps modulate the fermentation process in the gut,' Dr Naragund explains. By slowing carbohydrate absorption, psyllium reduces rapid fermentation that can lead to excess gas or ethanol production, stabilising blood sugar levels and improving gut transit.
To further support gut health, Dr Naragund suggests reducing processed carbohydrate intake, opting for whole grains, and maintaining a diet rich in fruits, vegetables, and lean proteins. 'Additionally, consuming probiotics — either through fermented foods or supplements – can replenish beneficial bacteria, while regular physical activity and stress management further contribute to overall gastrointestinal wellness.'
