Some E. Coli protect humans from more harmful strains.
Sometimes the enemy of your enemy is your friend.
Trillions of microorganisms live inside your gut.
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.
Diet reduces risk of depression through actions on bacteria in the gut, the immune system and the brain.
A world-first trial showed depression is reduced after just three months following a diet rich in vegetables, fruits, wholegrains, legumes, fish, lean red meats, olive oil and nuts.

A new study with fruit flies suggests that we may have less free will when it comes to choosing what we eat than we like to think.
Not quite yourself.
From losing inhibitions and anger to schizophrenia and dementia – science is uncovering the role small critters play in a range of illnesses and behaviours.
Screening and sterilisation processes mean human breast milk can be safely collected and frozen for use at a later time.
Banked breast milk is a safe source of shared human milk, and can be a life-saver for very premature babies.
Antibiotics: a new weapon to fight Parkinson’s?
A mouse study suggests that Parkinson's might start in the gut and later spread to the brain.
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?
Grapefruit diet? Probably not worth it.

The mystery of the yo-yo dieting effect has finally been solved.
If you don’t have a problem, you don’t need to mess with it.
The modern lifestyle, particularly diet and hygiene changes, have altered our relationship with our microbes. But can we restore it?
The gut of an obese person is more likely to contain bacteria that inflame the gastrointestinal tract and damage its lining.
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?
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?
You gotta have guts to succeed at Rio 2016 – and very healthy ones, at that.
Don’t undo all your good work by eating this on the weekend.
Yo-yoing between eating well during the week and bingeing on junk food over the weekend is likely to be just as bad for your gut health as a consistent diet of junk.
Being too clean isn't what's making us sick. It's the loss of biodiversity in the bacteria and organisms that live in our bodies and work with the immune system.
Allergies are becoming more frequent in the western world.
Allergies are reactions caused by the immune system as it responds to environmental substances that are usually harmless. But we don't yet have a cure or the ability to prevent them from developing.
When we think of antibiotic overuse, we don't generally think of allergies. Research is beginning to suggest that maybe we should.
Not quite true.
Severe allergies are on the rise – could our diet be to blame?
