Why Fibre Matters for Gut Health — And Why One Type Isn’t Enough

Your ancestors ate around 100g of fibre a day. Most adults today average only 17g — well short of the 25–30g recommended. Only a small proportion of the global population actually meets dietary fibre recommendations. Most people don't even know they're falling short. (1)

Why we need fibre

That fibre gap matters. Fibre intake connects to metabolic health, cardiovascular disease, colonic health, gut motility, colorectal cancer risk, and mortality.It’s also a primary food source for your gut bacteria. Without enough of it, the trillions of microbes involved in everything from digestion to metabolism don't have much to work with. (2)

Fibre also keeps you fuller for longer. Fibre, and its fermentation products, trigger signals from your gastrointestinal tract, including hunger-regulating hormones like GLP-1 and peptide YY. These travel to your brain and reduce food intake. Research has found fibre intake predicted weight loss in adults on calorie-restricted diets, with effects that appear more pronounced when kept up over time. (3)

Then there's what happens when bacteria ferment it. The resulting short-chain fatty acids (butyrate, propionate, and acetate) feed the lining of your large intestine, reduce inflammation, support appetite regulation, and help maintain the gut wall itself. (1)

Not all types of fibre do the same job

Not all fibres work the same way. Different types do different jobs. Most "high fibre" products lean on one source. Enough to put something on the label. Not enough to actually make a real impact. (1)

That’s why we put four in your mayo.

Psyllium Husk — The Heavy Lifter 

Forms a gel in your gut. Supports healthy cholesterol, steadier blood sugar, and bowel regularity. Old-school. Robustly studied.

Resistant Corn Fibre — The Overachiever 

Fuels gut bacteria, supports blood sugar control, and research suggests it helps your body absorb calcium more effectively. Dissolves completely. Does its job without anyone noticing.

Chicory Root Fibre — The OG Prebiotic 

One of the most studied prebiotic fibres on the planet. Selectively feeds beneficial bacteria. Keeps things moving.

Partially Hydrolysed Guar Gum — The Gentle One 

A well-tolerated, low-FODMAP fibre.A randomised controlled trial published in Nutrients found that three months of PHGG intake significantly improved stool form and increased Bifidobacterium abundance. This suggests it improves stool consistency by positively influencing your intestinal bacteria. (4)

Why different types of fibre matter for gut health

Your gut bacteria are the reason fibre works. They ferment it, they feed on it, and in return they help regulate your appetite, your metabolism, and inflammation throughout your body. Different bacterial strains prefer different types of fibre. Feed them only one and you're only looking after part of the community. Four fibres looks after the whole neighbourhood. (2)
