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.
A low diversity of gut bacteria may help explain heart attacks in young people, women and certain ethnic groups.
Sugar mama? Researchers are teasing out the benefits of various molecules in human milk.
A chemist explains how some molecules in human breast milk help fight infection. Understanding their properties could lead to better infant formulas that share the health advantages of breastfeeding.
Our obsession with gut health, diet and well-being is far from new: the Victorians had very similar concerns.
Researchers are getting closer to understanding how some people are more susceptible to posttraumatic stress disorder.

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.

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?
