We still don’t know what types of bacteria are truly beneficial.
Probiotics might avert a case of diarrhoea, or they could mean your gut takes longer to return to normal.
Hand washing is an effective way to help prevent the spread of bacteria.
Millions of bacteria live on our skin without making us sick. It's when they manage to get through that they can be dangerous – particularly if they're resistant to antibiotics.
Put down that bleach.
A sanitised environment can mean fewer helpful bacteria. That has some surprising consequences for the health of children.
Don’t scratch it!
Mosquitoes are picky about who they bite but it's not actually "us" that they're smelling when they choose their next meal...
If you eat a healthy diet, it’s probably not worth it.
Probiotics have been proclaimed by many as the answer to all sorts of health issues and conditions. But what exactly are probiotics? And, more importantly, should you be taking them?
With all the different types of yogurt on offer, making a decision on which one to buy can be difficult.
Consuming yoghurt is associated with many health benefits. But with all the varieties of yoghurt, and added ingredients like fruits and probiotics, it can be hard to know which is best for your health.
An expert explains how often you should poo and what it should look like.
The health benefits of being close to nature are well established.

Health benefits of being close to nature are well established, but the rise of apartment living means we can't always be close to greenery.
People with chronic bowel conditions may need to use the toilet 20 to 30 times a day.
Our brain and gut are constantly talking to each other, so it makes sense mental health and stomach issues have a close relationship.
Each person’s unique gut microbiota composition is in continuous communication with the immune system.
The composition of bacteria in our gut regulates our immune system. Modifying it - through poo transplants for example - can control cancer risk, as well as response to treatment.

We need micro-environmentalists to fight for the cause.
Micro changes have macro results.

New research suggests our gut microbes have their own circadian rhythms that in turn influence our organ functions. Is this an explanation for how disrupting our daily patterns can cause health problems?
The mode of delivery has a big impact on an infant’s microbiota, the bacteria that live in the gut.
The particular makeup of a newborn’s gut microbes is important as it has been shown to affect their risk of developing certain diseases later in childhood and adulthood.
What does it mean when it’s too hard or too soft?
For most of us, the form of stool we excrete can vary widely depending, in part, on what we've been doing.
The exact composition of each person’s microbiota is as unique as their finger prints.
The make-up of our gut is constantly changing and affects everything from our immune system and digestion, to our brain function.
There are several possible ways your gut bacteria could affect your brain.
Links have been made between the community of bacteria in your gut and depression, pain, stress and sleep. So what does the science say?
Probiotics are live microorganisms that have been delivering health benefits for thousands of years by helping to establish healthy gut microbiota.
The human gastrointestinal tract harbours trillions of microorganisms, with up to 1,000 or so different bacterial species.
The modern emphasis on sanitation has a role in our shrinking microbial populations.
Human activities have altered whole ecosystems with declines in species diversity, extinctions and the introduction of weeds and pests. But it's not just the outside world we're harming.
