A new randomised controlled trial, conducted by Gaylor et al,ⁱⁱ demonstrates that BENEO’s Palatinose^™ slow and sustained release carbohydrate improves aspects of sleep when consumed as a bedtime drink. By leading to more balanced blood glucose levels, particularly during the first half of the night, Palatinose^™ may support a longer deep sleep phase and thus restful sleep.¹ Based on this research, there is now even more evidence to show that Palatinose^™ provides a range of benefits beyond metabolic health.

Various studies worldwide have shown the prevalence of insomnia in 10 % – 30 % of the population, some even as high as 50 % – 60 %.ⁱⁱⁱ As poor sleep quality is known to be a risk factor for obesity, impaired glucose metabolism and dementia, insomnia is a major public health issue. With this in mind, the findings of Gaylor et al are of key importance, as they demonstrate that the right choice of carbohydrate can positively impact a person’s sleep and mental wellbeing.

The study was designed to explore the effect of Palatinose^™ (isomaltulose), compared to glucose, on a person’s sleep. Using a double-blind, randomised, placebo-controlled, cross-over design, the study was undertaken with 20 healthy young men, with a mean age of 24 years. The participants’ blood glucose was monitored continuously, and their sleep characteristic metrics were monitored in a laboratory setting using polysomnography and actigraphy.² One week after an acclimatisation night in the laboratory setting, half of the men were given 50 g of isomaltulose, while the other half received 50 g of glucose, dissolved in a 300 ml drink of water. A further week later, the participants who had had a glucose drink, received one with Palatinose^™ and vice versa. The format for all three visits to the laboratory was: all participants ate a standardised evening meal, and later viewed a series of neutral, positive and negative stories, then 15 minutes before bedtime, at approximately 11pm, the drinks were consumed. In the morning, story recall was tested.

The results showed that the participants who consumed the bedtime drink containing Palatinose^™ had a slower and more sustained release of glucose to their blood, preventing dips in blood sugar levels – particularly during the first half of the night. In addition, those who consumed the drink with Palatinose^™ during the second intervention had an extended deep sleep phase by an average of 22 minutes. This is because more balanced blood glucose levels promote deeper sleep and fewer periods of wakefulness. A better memory for neutral story content was also observed when Palatinose^™ was consumed as the second intervention.^iv

Commenting on the findings, Dr Stephan Theis, Head of Nutrition Sciences and Communication at BENEO, says: “These findings are significant, as deep or slow-wave sleep is important for physical recovery and cognitive health. By supporting balanced blood sugar levels and prolonging the deep sleep phase, Palatinose^™ may improve restful sleep and a person’s overall well-being. Its ability to sustain blood sugar levels overnight may also have far-reaching implications for dietary interventions, targeting sleep disorders and cognitive decline.”

BENEO’s Palatinose^™ (isomaltulose) is a naturally sourced, smart carbohydrate that provides full carbohydrate energy (4 kcal/g) in a more balanced way, thanks to its low-glycaemic profile. Being a sugar, Palatinose^™ has the physiology of a complex carbohydrate though, as it is slowly absorbed. Palatinose^™ is produced by the enzymatic rearrangement of the glycosidic bond between glucose and fructose in sucrose. As a result, it has slow-release properties and is non-cariogenic. It is also 100% vegan, kosher, halal, and non-GMO.

¹Palatinose^™ helps prevent counterreactions that interrupt sleep. That is because having more balanced blood glucose levels during the night has been shown to deactivate neurons that promote the release of hormones such as adrenalin or cortisol,.

The pandemic has shifted consumer views towards their health across the globe. New research results show that this pursuit for health will have an influence on the energy product market, as consumers demand healthier alternatives to boost their struggling energy levels. The survey was conducted on behalf of BENEO with 5,000 consumers across Spain, France, Germany, Poland and the UK.

Improving mental wellbeing, overall mood and physical energy levels were some of the most important health aspects that gained momentum as a result of the pandemic. According to BENEO’s research, almost 1 in 3 consumers in Europe have been juggling with feeling tired and a lack of energy during the pandemic. In order to improve energy levels, half of those surveyed said that they have been looking to food and drink products to help them make it through the day. This figure rises even more amongst younger adults (18 – 34-year-olds), with 8 out of 10 young European consumers seeking out energy-boosting products (increasing to 85 % in the UK). The demands of parenting during a pandemic have also left their mark, with 7 out of 10 European consumers with children saying they have turned to food and drink to boost their energy levels (growing to 82 % in the UK).

As well as fatigue being an increasing issue, the pandemic has also made people more aware of the fragility of health and the need to look after themselves. More than ever before, consumers are making the link between their diet and their health, with 63 % making an increased effort to eat and drink healthier in the future because of the pandemic. Also, staying fit and active and having a balanced diet have been major concerns during the pandemic and 2 in 3 consumers now see a healthy diet as key to controlling their future health.

A common way of boosting energy is via energy drinks, which have a wide appeal – being consumed by parents, young adults and gamers to name but a few. However, in light of the current trends, many consumers are looking for products in these categories with healthier attributes, more natural ingredients or benefits of sustained energy. At the same time, awareness is growing amongst consumers that some types of sugar are healthier than others. Today, 1 in 2 consumers see sugars or carbohydrates that have a lower impact on blood sugar levels as enticing. Additionally, 2 in 3 consumers find BENEO’s Palatinose^™ balanced sugar appealing because it supports a healthier lifestyle and provides sustained energy. This makes a compelling argument for the continued development of healthy alternative energy boosting products.

Myriam Snaet, Head of Market Intelligence and Consumer Insights at BENEO commented: “This survey quantifies the trend we have been seeing played out throughout the pandemic. The safeguarding of mental health and physical energy has now become key to European consumers. This higher interest in health and nutrition also links itself to an increased focus on preventative health, where blood sugar management can play a role. What is particularly interesting about this study is the significant size and diversity of the target group that is more interested in claims relating to balanced blood sugar levels. With such a broad appeal for healthy lifestyles, manufacturers who incorporate the balanced sugar, Palatinose^™, into their products will be well set to make the most of this trend both today and in a post-pandemic world.”

Palatinose^™, BENEO’s alternative sugar, is fully yet slowly digested and provides full carbohydrate energy but in a balanced and sustained manner, keeping blood glucose response under control. It occurs naturally in honey and is derived from sugar that is naturally extracted from sugar beets. Being low glycaemic, Palatinose^™ enables manufacturers to create products that deliver energy in a more balanced way, while improving blood sugar management.
