What’s tested
Everything in your 28-page report.
MY GUUT™ sequences the bacterial DNA in your sample to see which bacteria are present and in what proportions. Over 70 genera are reported. Here’s what each part means.
Diversity (Shannon index)
Diversity combines two things: how many different types of bacteria you have, and how evenly they’re spread. A gut dominated by a few types scores lower than one with many types in balance. Research links a varied, fibre-rich diet and regular exercise with higher diversity.
Dysbiosis index
A single score showing whether your overall mix leans towards organisms usually seen as helpful, or towards less helpful ones. It’s a summary, not a diagnosis.
Enterotype
Most people’s guts fall into one of three broad types, named after the group that leads: Bacteroides, Prevotella or Ruminococcus. Your enterotype tends to reflect long-term diet, such as how much animal protein or plant fibre you eat.
Firmicutes to Bacteroidota ratio
These are the two largest groups of gut bacteria. The report shows the balance between them. On its own the ratio says little, but it helps put the rest of your results in context.
Key species against reference ranges
Four groups of named bacteria, each shown as low, within range or high:
Probiotic
Bacteria often found in probiotic foods and supplements, such as Bifidobacterium and Lactobacillus, plus Akkermansia muciniphila.
Butyrate-producing
Bacteria that ferment fibre into butyrate, a short-chain fatty acid the cells lining your bowel use for energy. Examples include Faecalibacterium prausnitzii and Roseburia.
Mucin-associated
Bacteria that live in and feed on the mucus layer of the gut wall, such as Akkermansia muciniphila and Bacteroides fragilis.
Sulphate-reducing
Bacteria that produce hydrogen sulphide, such as Bilophila wadsworthia and Desulfovibrio. Small amounts are normal.
Diet suggestions
Based on what you’re low in, the report suggests fibres and foods that may feed those bacteria, with a realistic idea of how long change takes. Gut bacteria shift over weeks to months, not days.
Population “tendencies”
Some report sections describe a tendency, for example towards IBS-type or weight-related patterns. These are statistical links seen across large groups of people with similar results. They are not findings about you and they are not a diagnosis.
