The human microbiome, a complex ecosystem of trillions of microorganisms, plays a vital role in digestion. These bacteria, fungi, and viruses primarily reside in the gut, aiding in breaking down food, absorbing nutrients, and maintaining a healthy digestive system. Beneficial bacteria, such as Lactobacillus and Bifidobacterium, help in fermenting fibre, producing essential vitamins like B and K, and preventing harmful pathogens from colonising the gut.

An imbalance in the microbiome, known as dysbiosis, can lead to digestive disorders like irritable bowel syndrome (IBS), bloating, and diarrhoea. Diet, antibiotics, and lifestyle choices significantly impact microbiome health. Consuming probiotics and fibre-rich foods supports a balanced gut flora.
