Gut microbiota: what it is and how to look after it every day

3 November 2026

Trillions of microorganisms live in the gut, forming an ecosystem of their own. We explain what we know about the microbiota and which habits are within your reach.

For years the gut was seen as nothing more than a digestive tube. Today we know it is home to a huge ecosystem: the gut microbiota, made up of trillions of bacteria and other microorganisms.

What we know (and what we do not)

Research on the microbiota is moving very fast. Some things are fairly clear:

Everyone has a different microbiota, which changes with age, diet and lifestyle.
A diverse microbiota is generally associated with a gut in good condition.
Diet is one of the factors that shapes it most.

Many other questions are still being studied. Be wary of anyone promising quick results.

Habits that support it

Varied fibre. Vegetables, fruit, pulses, nuts and wholegrain cereals. The more variety of plant foods each week, the better.
Fermented foods, such as yoghurt or kefir, as part of a balanced diet.
Enough water throughout the day.
Regular physical activity and fairly regular mealtimes.
Rest. Sleep and stress also show in the gut.

Beware of sudden changes

If you increase your fibre intake, do it gradually and drink more water: a sudden change can cause wind or bloating in the first few days.

When to see a doctor

If you notice persistent changes in your bowel habits, pain, blood in your stools or unexplained weight loss, see your doctor. These are signs that need to be assessed.
