One in five Brits admit they are falling short on their fibre intake, according to research. The study of 2,000 adults revealed that almost half were unaware the recommended daily allowance of fibre stands at 30g. Moreover, a quarter admitted they are clueless about how to boost their fibre intake and struggle to choose foods which contain it.

The research showed that three in ten had no idea raspberries are a fibre source, while 47% were oblivious dark chocolate contains it too. Furthermore, over a fifth (21%) were unaware that avocados deliver fibre - a food typically linked with 'healthy fats'.

The study discovered that a whopping 66% of individuals didn't recognise symptoms like mood fluctuations and post-meal tiredness could be connected to inadequate fibre consumption. Additional indicators of fibre deficiency include depleted energy levels, mental cloudiness, and persistent hunger pangs.

Nutritionist and fibre specialist Kristen Stavridis, who is working alongside Strong Roots Sweet Potato Fries, highlighted the vital importance of this nutrient.

"Fibre plays a crucial role in digestion, energy levels and blood sugar balance, yet it's one of the most commonly overlooked nutrients," she said. "Many people don't realise that everyday foods, including vegetables, can make a meaningful contribution to their daily fibre intake when eaten regularly."

She pointed out one unexpected source: "Sweet potatoes are a natural source of fibre and also provide key nutrients such as vitamin A and potassium. However, the research suggests many people still fail to recognise them as part of a fibre-rich diet."

The survey highlighted broader nutritional concerns, showing just 11% of Britons consume the advised five portions of fruit and veg daily, while 53% feel health trends change so fast they can’t keep up.

That said, 42% reckon people are taking nutrition more seriously now compared to ten years ago, based on OnePoll.com data.

Kevin Friel, spokesperson for Strong Roots Sweet Potato Fries, which are a source of fibre, commented: "So many people are at a loss when it comes to fibre.

"It's a vitally important part of a healthy, balanced diet, and something nearly everyone could benefit from eating more of."

He recommends implementing straightforward adjustments: "Making small meal swaps can really help boost fibre intake, you really can eat your chips for more fibre.

"Swapping regular white potato chips for sweet potato fries is one simple change, they contain 4.1g of fibre per 100g and just one portion contributes towards the recommended daily intake."
