The supplement aisles of most grocery stores and pharmacies in the United States are bursting with probiotics. These billions of bacteria stuffed into once-a-day capsules claim to provide digestive relief, among other benefits. They're extremely popular, with sales of $36.6 billion in 2015.

You are what you eat, and so are the bacteria that live in your gut. Microbiologists have known for some time that different diets create different gut flora, but previous research has focused on mice instead of humans, leaving the actual relationship between our food and our stomach bacteria unclear. A new study, published Wednesday in Nature, indicates that these changes can happen incredibly fast in the human gut—within three or four days of a big shift in what you eat.

Recent headlines proclaimed an Australian-developed pill might be able to help those with coeliac disease eat wheat without becoming ill. But the fine print says it's no treatment or cure.

For 22 years, Michelle O'Connor from Derbyshire struggled with debilitating gut symptoms. She has bile acid malabsorption, which affects a million Britons a year, and is often misdiagnosed by doctors.

Great news for those with the notoriously hard to treat condition. The problem may be a fungus.

Over recent years, the number of people following a gluten-free diet has more than tripled, a new study has found, though the rates of coeliac disease - which causes gluten intolerance - have remained the same.

The mere mention of a 'faecal transplant' might be something that makes a lot of us squirm, but the truth is that poo transplants from one person to another are an increasingly popular treatment for a range of illnesses. But what's actually in a...
