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.
