While many Brits want to increase their fibre intake, most are unsure how much they need, shows a recent study based on a nationally representative survey of 2,000 UK adults by Weetabix.
The research by Weetabix revealed a notable gap between perception and reality. 49 per cent of respondents feel confident in their fibre knowledge, and 52 per cent believe they meet daily targets. Yet only 8 per cent correctly identify the recommended 30g daily intake, with the average estimate just 22.9g.
Encouragingly, awareness of fibre’s benefits is high. 81per cent of Brits say it’s important, primarily for digestive health, with 66 per cent linking it to a healthy digestive system and 49 per cent to preventing constipation.
Among those not getting enough fibre, lack of knowledge is the top barrier (35 per cent), especially among men (39 per cent), despite their higher confidence levels. While 18 per cent of respondents cite the cost of high-fibre foods, fibre-rich options such as wholegrains, fruit, vegetables and pulses remain affordable and widely available. Practical, everyday strategies, like starting the day with a wholegrain breakfast, can make it easier to reach targets.
Interest in fibre is high, with more than half (57 per cent) eager to learn how to increase their intake, climbing to 71 per cent among young adults (25–34-year-olds). This curiosity is translating into action, as 45 per cent report making changes to include more fibre in their diet.
Among younger adults, social media is also influential, with 28 per cent of 18–34-year-olds considering it a reliable source. Trends like “fibremaxxing” also highlight the growing popularity of gut health discussions across social media.This shows many people are unknowingly falling short, but expert guidance can help close this knowledge gap and support people in reaching recommended intake levels.
With decades of wholegrain expertise, Weetabix provides practical, everyday tips to make fibre simple and achievable.
Consultant Dietitian to the Weetabix Food Company, Sian Porter, shares her advice, “The easiest ways to increase fibre are to add fibre-rich ingredients to meals and make simple additions or swaps, such as adding fruit to your cereal, sprinkling nuts or seeds on yoghurt or soup, choosing wholegrains over white rice or pasta, keeping edible skins on fruit and veg, and swapping snacks like crisps for nuts or meat for beans and lentils. Build these changes gradually and remember to drink plenty of fluids.”
