Zoe survey exposes UK’s widening fibre gap

A new Zoe survey has delivered one of the starkest assessments yet of the UK’s nutrition crisis, revealing that 90% of adults do not know the recommended daily fibre target — and only 5% actually meet it.

The findings land at a moment when poor diet has overtaken smoking as the leading cause of preventable death and chronic illness in the UK, underscoring the scale of the challenge facing both policymakers and the food industry.

For food and drink manufacturers, the data signals a shift in public expectations and a growing scrutiny of how products are formulated, labelled and marketed.

A fibre gap with real health consequences

Zoe’s survey of 2,000 UK adults highlights a profound disconnect between dietary needs and consumer behaviour. The recommended daily fibre intake is 30g, yet the average adult consumes just 16.4g. This shortfall is linked to rising rates of constipation, digestive disorders and increased risk of cardiovascular disease, type 2 diabetes, metabolic syndrome, stroke and certain cancers.

The lack of awareness is striking: nine in ten people cannot identify the target, and fewer than one in four recognise poor diet — not smoking — as the leading cause of preventable deaths.

For producers, this gap represents both a challenge and an opportunity. Products with higher fibre content, clearer nutritional cues and reduced reliance on ultra‑processed formulations are likely to become more commercially and politically important.

Public confusion — and mistrust

The survey paints a picture of consumers struggling to navigate an ultra‑processed food environment:

• Misleading packaging claims: two‑thirds of respondents say they have felt misled by on‑pack marketing.
• Demand for clearer guidance: 69% would make different choices if they had better information about which foods support health.
• Low confidence in government policy: only 9% believe the government takes the nation’s diet “very seriously”.

This erosion of trust places greater pressure on manufacturers to demonstrate transparency, reformulate responsibly and avoid health‑washing claims that could be perceived as deceptive.

The findings carry several strategic implications for the sector:

• Reformulation pressure will intensify: With fibre intake so low, producers may face calls to increase plant‑based ingredients, wholegrains and minimally processed components.
• UPF scrutiny is accelerating: With 60% of the UK diet now ultra‑processed, Zoe’s findings strengthen the case for regulatory intervention — from warning labels to sugar‑tax expansion.
• Packaging claims will face tougher oversight: As consumers report feeling misled, regulators may tighten rules around “high fibre”, “natural”, “plant‑based” and similar claims.
• Menopause and personalised nutrition markets are underserved: Nearly half of women surveyed do not know diet can support menopause symptoms — a gap that brands could address with evidence‑based innovation.
• Mood and sleep benefits are emerging purchase drivers: Over 80% believe diet affects mood and sleep, signalling demand for products that support holistic wellbeing.

A call for systemic change
Professor Tim Spector, Zoe’s scientific co‑founder, argues that the UK’s food environment — not individual behaviour — is the root of the problem. He calls for mandatory UPF warning labels, an expanded sugar tax and a reduction of ultra‑processed foods in schools and hospitals.

He also frames the issue as an economic one, noting that the new Health Secretary, James Murray, has an opportunity to treat nutrition as a national priority.

“People want to make healthier choices, but they are being thwarted by deceptive marketing and a lack of clear guidance,” Spector says. “This isn’t a failure of personal willpower; it’s a failure of policy.”

Brands that can deliver higher‑fibre, minimally processed, transparently marketed products — and back them with credible science — will be better positioned as the regulatory landscape tightens.
