When carbs go wrong: How eating bread can make you feel drunk

Whether it’s toasted, baked, or grilled, bread rises to the occasion every time. From crusty baguettes to pillowy sandwich loaves, this humble staple brings comfort and flavor to our mornings—especially when topped with jams, cheeses, eggs, or savory spreads. Versatile, delicious, and always within reach, bread is the ultimate breakfast hero.

However, if bread is a daily staple in your diet, there’s an important caveat to keep in mind. Holistic health guru, Dr Mickey Mehta recently shared a video explaining how bread causes auto-brewery syndrome.

In his post, he urges those who rely on bread every morning to try and reduce it. "Because bread could be the most dangerous thing you put in your body," he said.

What is auto-brewery syndrome?

This condition, also known as gut fermentation syndrome, is a rare medical disorder in which the body produces alcohol internally. It occurs when carbohydrates ferment in the gastrointestinal tract due to certain microorganisms, leading to symptoms of intoxication—even without consuming any alcohol.

The condition occurs when certain yeasts or fungi—most commonly Saccharomyces cerevisiae or Candidaspecies—overgrow in the gut.

Treatment usually includes antifungal medications, dietary modifications, and probiotics to help restore a healthy balance in the digestive system.

What are the symptoms?

The symptoms include:

1. Dizziness

2. Disorientation

3. Headache

4. Dry mouth

5. Nausea or vomiting

6. Fatigue

7. Mood changes

8. Lack of concentration

9. Dehydration

In severe cases, it could also lead to chronic fatigue syndrome, depression or anxiety and irritable bowel syndrome.

People with this condition are often advised to avoid foods high in simple carbohydrates and sugars, such as corn syrup, high-fructose corn syrup, white bread and pasta, white rice, white flour, potato chips, crackers, sugary beverages, and fruit juices.
