What is Gut Health?

Gut health¹ refers to the absence of gastrointestinal symptoms, such as abdominal pain or diarrhea, and disease (e.g. Inflammatory Bowel Disease.)

The concept of gut health has recently garnered a lot of mainstream attention, but there is yet to be a concrete definition. Typically, gut health includes:

  • Absence of gastrointestinal disease or symptoms
  • Absence of undesirable local conditions, such as increased intestinal permeability, mucosal inflammation and deficiency
  • Good function of processes linked to the gastrointestinal (GI) tract, such as the digestion and absorption of food
  • Balance of microbes living in the GI tract – the microbiome
