There are hundreds of different microorganisms in the digestive system. The majority of these are bacteria, most of which are friendly.
Friendly bacteria produce important nutrients and help break down fibre that the body can’t digest.
Both human and animal studies have found that normal-weight people have different gut bacteria than overweight or obese people.
Probiotics are live bacteria and yeasts that are good for a person’s gut. They are often called ‘good’ or ‘helpful’ bacteria because they help keep the gut and digestive system healthy.
Probiotics also help a person to shift their belly weight which is a concern for most. This is achieved by the live microorganisms that have health benefits when eaten.
They are found in both supplements and fermented foods. Probiotic supplements may improve digestion health, heart health and immune function.
