A sanitised environment can mean fewer helpful bacteria. That has some surprising consequences for the health of children.
Many probiotic bacteria don't manage to colonise the gut, but that doesn't mean they don't have positive health benefits.
Clinical trials involving probiotics are failing to report on the safety and harms of these treatments.
Gut microbe metabolites can tell us a lot about our health.
In the largest citizen science experiment to date, 11,336 people sent poop samples to this San Diego lab so that microbiologists could figure out how the microbes in our guts make us healthy or sick.
There's growing evidence poo transplants can work for some conditions, including a type of diarrhoea. But they're not for everyone.
Our brain and gut are constantly talking to each other, so it makes sense mental health and stomach issues have a close relationship.
Trillions of microorganisms living inside your digestive system may influence your health and even your weight. Here's how your gut may communicate with your brain, bone marrow and immune system.
For most of the twentieth century, we were at war with microbes, leading to substantial changes in our body's ecosystem. This has changed our diets, disease profile, moods and even personalities.
Upping your intake of vegetables and fruits can do more than just reduce your risk of heart disease, diabetes and cancer – it could also help you breathe easier.
Long viewed simply as 'germs,' the hidden half of nature turns out to be crucial to the health of people and plants.
Low fibre eaters gain weight more quickly and may be more susceptible to certain illnesses.
When we can't lose weight, we tend to want to blame something outside our control. Could it be related to the mictobiota – the bacteria and other organisms – that colonise your gut?
There's more to fermented foods than a good meal. Scientists are learning just how such foods encourage the growth of probiotics and how this keeps people healthy.
Shoppers have had it with supermarket science and instead are embracing more holistic styles of eating.
