naxus in gut health formula

4 reasons to include Naxus® in your gut health formulation

4 reasons to include Naxus® in your gut health formulation

Maastricht, 15th March, 2024

Arabinoxylans are essential prebiotics that exert beneficial effects on human health, particularly gut health. The relationship between diet and gut health has gained popularity in the last decades, with promising research emerging at an increasingly rapid pace. For product developers, it can be challenging to decide which ingredients to include in their gut formulation. In this article, you will discover 4 compelling reasons to include Naxus® in your gut health formulation.

What is Naxus®?

Naxus® is a patent-protected, prebiotic arabinoxylan extract sourced from the wheat endosperm. It can boost the immune system and improve gut health.

Solabia-BioActor developed Naxus® and conducted extensive research in collaboration with Maastricht University, Wageningen University & Research, Institute Pasteur and more, demonstrating its positive effects in numerous studies.

Clinical research in diverse populations shows that Naxus® promotes gut health by improving intestinal barrier function, increasing beneficial micro-organisms (e.g., Bifidobacteria and Bacteroides), improving the short-chain fatty acid (SCFA) profile and inducing cytokine and chemokine production (1, 2, 3).

Naxus® exerts its beneficial effects at doses starting at 1 g. Click below to see the scientific evidence.

4 reasons why Naxus® is a great addition to gut health formulations

If you are considering including Naxus® in your formulation for gut health, you should consider the following aspects:

 

1. Naxus® improves SCFA profile and strengthens the gut barrier

Health-promoting micro-organisms are present in the gut and help to protect the gut wall from pathogens and bad bacteria. Studies have demonstrated that Naxus® supports the growth of beneficial microbiota (1). Consequently, these microbiota produce advantageous SCFAs like propionate and butyrate.

SCFA production is related to a variety of positive health effects. To illustrate, these metabolites reduce the risk of developing inflammation and promote psychological and physical health. Moreover, they regulate the host immune system and improve metabolic health (4, 5).

 

2. Naxus® supports the immune system 

Naxus® has proven immunomodulatory properties by enhancing gut barrier integrity and improving the adaptive and innate immune system.

Research indicates that Naxus® improves multiple gut barrier parameters such as reduced intestinal permeability, increased goblet cell number, and higher intestinal immunoglobin A concentrations (6).

Additionally, Naxus® has been shown to increase vaccination efficacy against influence resulting in fewer adverse events, fewer respiratory tract infections, and improved seroprotection rates (7).

Moreover, Naxus® improves the innate immune system, leading to an increased immune system vigilance (2, 3).

 

3. Naxus® is slowly fermentable without bloating

Naxus® is composed of long and complex carbohydrate molecules, that ferment slowly and gradually (8). Therefore, Naxus® has an advantage over other fibres like inulin, because it does not cause intestinal complaints such as bloating and gas formation in the gut.

 

4. Naxus® can be used in many formulation types

Arabinoxylans, with their favourable physicochemical properties, have been successfully incorporated into numerous food products. Naxus® is wheat-derived and gluten-free and is therefore suitable for various formulations.

Naxus® has an emulsifying capacity and influences the viscosity of multiple foods. Its effects have been tested in products such as pasta, bread, beer, cakes, and cookies. For example, in the bread-making processes, arabinoxylans positively affect dough consistency, loaf volumes, crumb structure, and bread staling.

These beneficial technological characteristics prove the potential to include Naxus® in any gut health formulation.

 

Naxus®, the key ingredient for your gut health formulation

Naxus® contributes to your gut health by improving the microbiome, protecting the intestinal gut barrier, and supporting the immune system. It is a patent-protected product that bears an EFSA claim for reduction of post-prandial glycemic response and can be incorporated into multiple food products due to its beneficial properties.

Its innovative and science-based nature makes it a valuable addition to optimise your gut health formulation!


benefits of prebiotics

What are prebiotics? Types and health benefits

What are prebiotics? Types and health benefits

Last updated: February 22nd, 2024

February 7th, 2022

Prebiotics are a big topic in nutrition these days. As with probiotics, their relationship with human health has gathered a lot of interest in recent years. Prebiotics are compounds derived from non-digestible carbohydrates that confer health benefits to the host by selectively stimulating the growth of intestinal bacteria.

benefits of prebiotics

What are prebiotics?

Prebiotics are non-digestible food ingredients that confer health benefits to the host by selectively stimulating the growth and/or activity of a limited number of our intestinal bacteria [1].

Fructo-oligosaccharides (FOS), galacto-oligosaccharides (GOS), and trans-galacto-oligosaccharides (TOS) are the most common prebiotics.

Fermentation of prebiotics by gut microbiota produces short-chain fatty acids (SCFAs), such as lactate, butyrate, and propionate. These SCFAs have multiple beneficial effects on the body and gut health, as SCFAs are small enough to enter blood circulation through gut cells.

The difference between probiotics and prebiotics is that, while probiotics are beneficial bacteria, prebiotics are the food for these bacteria. Both are important for human health, but they have different roles. Probiotics are live bacteria and prebiotics are compounds derived from non-digestible carbohydrates such as fibre.

What are the different types of prebiotics?

There are various types of prebiotics. These include:

• Fructans such as inulin and fructo-oligosaccharides (FOS) can promote directly or indirectly several bacterial species.

• Galacto-oligosaccharides (GOS) can greatly stimulate Bifidobacteria and Lactobacilli, as well as Enterobacteria, Bacteroidetes and Firmicutes to a lesser extent [2].

• Hemicellulose-derived oligosaccharides such as arabinoxylans. Arabinoxylans could produce a strong prebiotic activity, in particular bifidogenic.

• Starch and glucose-derived oligosaccharides, a type of starch resistant to small intestine digestion, can stimulate the production of butyrate, a short-chain fatty acid (SCFA) [3]. Polydextrose, a glucose-derived oligosaccharide, can also stimulate Bifidobacteria [4].

• Pectic oligosaccharides (POS): some oligosaccharides come from a polysaccharide called pectin. This type of oligosaccharide is called pectic oligosaccharide (POS).

• Non-carbohydrate oligosaccharides: although carbohydrates are more likely to meet the criteria to be considered prebiotics, there are other compounds not classified as carbohydrates, but that can be classified as prebiotics, such as some flavanols [5].

Did you know you can combine prebiotics and probiotics to create synbiotic dietary supplements? Read more about that here!

What are the health benefits of prebiotics?

Research shows that prebiotics have a beneficial effect on gut health, which is directly linked to overall well-being. In addition, prebiotics exert their positive effects via the following pathways:

• Microbiota support: prebiotics provide energy sources to gut microbiota. This way, they are able to modulate the function and composition of these microorganisms [6].

• Immune system modulation: SCFAs have multiple benefits for the immune system, such as increasing antibody responses towards pathogens [7].

• Colorectal cancer risk reduction: fermentation products of probiotics, such as butyrate, have possible protective effects against the risk of colorectal cancer [8].

• Infants gastrointestinal disorder prevention: prebiotics can redice the risk of development of necrotizing enterocolitis in preterm infants [9].

• Skin irritation conditions: the risk of development and the severity of atopic dermatitis [10, 11] could decrease after prebiotic intake.

• Cardiovascular diseases (CVD) risk reduction due to the potential of prebiotics to reduce inflammatory markers and improve lipid profile [7].

How can I add prebiotics to my diet?

Prebiotics play an important role in human health, so it is important to consume them. They can be found in foods that are high in fibre, such as vegetables, fruits, legumes and whole-grain products. Foods that are high in prebiotic fibre include:

• Wheat
• Soybeans
• Oats
• Bananas
• Tomatoes
• Berries
• Asparagus
• Garlic
• Leeks
• Onions
• Chicory

Another option to increase prebiotic intake is supplements, purchased in health food stores and online. They are usually available in capsule form, in powder blends or even in bars.

Prebiotics are generally considered safe. They can have some minor side effects, such as diarrhea, bloating and flatulence. However, prebiotics’ chain length is the main parameter related to the development of these side effects.

Prebiotics with a shorter chain length have more side effects because they ferment earlier and more rapidly, while longer chain prebiotics – such as arabinoxylans from wheat– ferment slowier.


postbiotics

Exploring the power of postbiotics: benefits and uses

Exploring the power of postbiotics: benefits and uses

October 18th, 2023

Currently, probiotics and prebiotics are widely known for their favorable impact on gut health. More recently, the focus has expanded to include postbiotics, which encompass products or byproducts generated through microbial fermentation and are also acknowledged for their health advantages. Nevertheless, these postbiotics remain unfamiliar to most consumers. Dive into our new blog to find out more!

postbiotics

What are postbiotics?

Gut health is key to your overall well-being and there are many ways to support your gut health. Prebiotics and probiotics are well-known, but what about probiotics?

Postbiotics encompass a class of substances defined as “preparations containing non-living microorganisms or their components, which bring about positive health effects for the host.” In simpler terms, they refer to the byproducts or metabolic products that result from the fermentation processes of bacteria.

This category of postbiotics encompasses various kinds of compounds. Among them are short-chain fatty acids, known for their multiple health advantages, as well as fragments of microbial cells, functional proteins, extracellular polysaccharides, cell lysates, and teichoic acid.

In contrast to probiotics, postbiotics offer health benefits without requiring a live state. This characteristic contributes to their stability compared to the live bacteria they originate from. [1]

Why should I use postbiotics?

A question on your mind might be: why should you consider postbiotics when you’re already using pre- and probiotics?

It’s crucial to recognize that everyone’s gut microbiota composition differs. As a result, the way various components are processed can vary from person to person.

This means that the impact of probiotics and prebiotics on health can differ among individuals. A way to control for this is by consuming postbiotics. You are then directly taking the beneficial components, so differences in microbiota composition don’t have an effect in this case.

If you’re interested in learning more about prebiotics, you can refer to this article. Alternatively, if you’re already familiar with prebiotics, you might find this article on synbiotics to be of interest!

What are the advantages for health that postbiotics offer?

Research indicates that postbiotics can bring forth a range of health benefits, including:

Balancing the microbiota: Elements found in postbiotics, like butyrate, a type of short-chain fatty acid, prove advantageous for maintaining gut health. [2]

Influencing the immune system: Butyrate has the ability to trigger the generation of T cells within the intestinal tract, thereby aiding in the regulation of immune responses. Additional components, such as fragments of microbial cell walls, can enhance the production of cytokines—chemical messengers that mitigate inflammation and bolster immune reactions. [2,3]

Shaping metabolic processes: Short-chain fatty acids such as propionate play a role in enhancing insulin sensitivity and glucose tolerance. Simultaneously, butyrate spurs the generation of an antioxidant called glutathione. [1,2]

Assisting in weight loss: Short-chain fatty acids could contribute to weight loss by influencing eating behaviors. This is attributed to the release of hormones that induce a sense of fullness. [1]

Easing symptoms of irritable bowel syndrome (IBS): In a study involving 443 individuals with IBS, the administration of orally ingested, heat-inactivated Bifidobacterium bifidum, a postbiotic, notably alleviated IBS-related symptoms such as abdominal pain, discomfort, bloating, and irregular bowel habits. [4] Curious to read about the effect of pre- and probiotics on IBS symptoms? Read more here!

Potential additional advantages: Administering inactivated lactic acid bacteria orally might aid in eradicating Helicobacter pylori infection, addressing chronic unexplained diarrhea, and mitigating the adverse impacts of stress. [1]

How can I incorporate postbiotics into my diet effectively?

Postbiotics might not be as readily available as probiotics and prebiotics, but you can acquire them from health food stores or online retailers. They are generally regarded as safe and well-tolerated.

Given that postbiotics are a product of bacterial fermentation within your gut, you can enhance their production by consuming foods abundant in probiotics and prebiotics. Probiotic-rich options include fermented foods like yogurt, kefir, tempeh, and kombucha. For prebiotics, focus on incorporating high-fiber foods into your diet, such as vegetables and whole-grain products.

how a healthy microbiome boosts your immune system

How a healthy microbiome boosts your immune system

Unlocking the power of your gut: how a healthy microbiome boosts your immune system

August 18th, 2023

Did you know that your immune system’s performance is intricately tied to the health of your gut microbiome? In this article, we delve into the fascinating connection between your gut microbiome and immune system. Discover the key role of the gut microbiome in immune function and learn about the dietary components that can nurture a diverse and thriving gut ecosystem.

how a healthy microbiome boosts your immune system

A symbiotic relationship: gut microbiome and immune system harmony

The human body is a bustling ecosystem housing trillions of microorganisms, collectively known as the microbiome. Among these, the gut microbiome stands out as a vibrant community of bacteria, viruses, fungi, and parasites (1).

This intricate network collaborates to maintain a balanced blend of beneficial microorganisms, protecting us from potential invaders.

Recent advancements have illuminated the gut microbiome’s dynamic involvement in our well-being, extending beyond passive existence.

This intricate web of microorganisms actively influences various bodily functions, including bolstering the development and efficacy of the immune system. Our immune system, in turn, maintains a delicate equilibrium, defending against pathogens while avoiding autoimmune responses (2).

Microbiome’s immune-boosting strategies

Short-Chain Fatty Acids (SCFAs)

At the heart of the gut microbiota’s influence on immunity lies the production of Short-Chain Fatty Acids (SCFAs) through dietary fiber fermentation in the large intestine (3).

These SCFAs, such as acetate, propionate, and butyrate, play a pivotal role in maintaining gut balance and modulating immune responses. They orchestrate immune cell functions, like regulatory T cells and antigen-presenting cells, and stimulate cytokine and chemokine production, bolstering immunity.

Furthermore, SCFAs can directly quell pathogenic activity by suppressing virulence-related genes, curbing potential threats.

Fortifying the barricade: tight junctions

The gut’s tight junctions act as gatekeepers, upholding the integrity of the intestinal barrier (4). Inflammation or infections can disrupt these barriers, allowing undesirable substances to escape into the bloodstream, triggering immune responses (5, 6).

SCFAs step in as allies here, contributing to the assembly of robust tight junctions within intestinal cell walls. This reinforcement prevents the escape of harmful toxins from the gut, bolstering the gut wall’s ability to shield against infections (5).

When this symbiotic relationship thrives, the immune system guards us against infections. However, an unbalanced microbiota composition might trigger inflammation, autoimmune disorders, and chronic diseases (1, 5).

Strategies to help the gut ecosystem flourish

A diverse and balanced gut microbiome is universally recognized as vital for our health (7). Research highlights that such diversity empowers immune responses against infections while reducing autoimmune responses. Conversely, a low-diversity microbiome is linked to chronic inflammation and an elevated risk of colorectal cancer.

To nurture a flourishing and diverse gut microbiome, prioritizing a balanced diet and healthy lifestyle is very important.

Choose for a spectrum of fruits, vegetables, whole grains, and lean protein sources. These foods, rich in fiber, prebiotics, and nutrients, provide nourishment for beneficial gut bacteria.

1. Fiber: the gut’s aid for immunity

Fiber’s role in gut health is crucial, as it bolsters microbiome diversity. A diet rich in fiber, found in fruits, vegetables, and whole grains, enhances gut bacteria abundance and diversity. This, in turn, augments immune function, reducing chronic disease risks (8).

2. Prebiotics: fuel for beneficial bacteria

Prebiotics, a specific type of fiber, serve as sustenance for our beneficial gut inhabitants. Foods like onions, garlic, leeks, asparagus, bananas, and whole grains are brimming with prebiotics, nurturing a thriving microbial community.

3. Water: hydration and gut motility

Staying hydrated is crucial for optimal gut function. Drinking plenty of water helps maintain proper gut motility and prevents constipation. Adequate hydration supports the movement of food through the digestive tract, allowing beneficial bacteria to thrive and contribute to a healthier gut.

4. Probiotics and postbiotics: allies for immunity

Fermented foods like yogurt, kefir, sauerkraut, and kimchi harbor probiotics—live bacteria conferring health benefits. Additionally, postbiotics, metabolic by-products or components produced during fermentation, like SCFAs, amplify the benefits. Consuming these products directly ingests these components, bolstering health.

5. Synbiotics: Uniting Prebiotics and Probiotics

Synbiotics, the blend of prebiotics and probiotics, synergistically promote gut health. Examples include yogurt with inulin or fructooligosaccharides (FOS), and kefir with galactooligosaccharides (GOS).

6. Reducing stress levels

Besides diet-related strategies, there are other ways to help your gut stay healthy. Stress can negatively impact the gut-brain axis and disrupt gut health. Practicing stress-reduction techniques like meditation or deep breathing can have a positive impact on both your mental well-being and gut health.

Cultivate your gut for immune resilience

In summary, the gut microbiome profoundly impacts the immune system’s effectiveness. A thriving and varied gut ecosystem fortifies us against infections and chronic ailments, while an imbalanced one heightens vulnerability. By embracing a well-rounded diet full of fiber, prebiotics, and fermented foods, we can nurture our gut microbiome, bolstering overall health.


New publication Naxus® consumption supports weight management through reduction of actual calorie intake in an ad libitum meal

New publication: Naxus® consumption supports weight management through reduction of actual calorie intake in an ad libitum meal

New publication: Naxus® consumption supports weight management through reduction of actual calorie intake in an ad libitum meal

Maastricht, The Netherlands, 27th July 2023

Press release
This randomized controlled crossover study showed Naxus®’ potential for appetite control and weight management. In a 21-day trial with healthy adult males, it was reported that consumption of a blend of Naxus® and inulin showed significantly lower calorie intake in an ad libitum meal (838 kcal vs. 1023 kcal) while reporting no changes in appetite. The blend was also shown to increase faecal SCFA concentrations. These results highlight Naxus®’s potential to transform appetite regulation.

New publication Naxus® consumption supports weight management through reduction of actual calorie intake in an ad libitum meal

Naxus®: clinically validated and developed by BioActor

Naxus® is a clinically validated arabinoxylan extract developed by BioActor, derived from wheat endosperm. It has been extensively studied and shown to have beneficial effects on microbiota composition, glycaemic control, and immune system function.

Naxus® promotes the growth of beneficial bacteria, production of Short Chain Fatty Acids (SCFA) and improves glycaemic control by inducing GPR43 signaling which leads to reduced glucose peaks and improved insulin sensitivity (1, 2). It also strengthens the immune system through various mechanisms (3, 4, 5). It is a well-researched ingredient with significant potential for enhancing overall health and well-being.

The study: Chronic consumption of a blend of inulin and Naxus® reduces energy intake in an ad libitum meal but does not influence perceptions of appetite and satiety

Introduction

Two dominant bacterial strains account for more than 90% of the total bacterial gut community: Bacteroidetes and Firmicutes (6). They are widely believed to have important effects on the maintenance of normal intestinal homeostasis. Stressors associated with modern lifestyles (e.g. low fibre diet) can chronically change the bacterial gut composition and lead to the increase of more virulent microbes that adversely affect the health of the host.

Gut microbiota break down fibre from our diet and produce SCFAs such as propionate, acetate, and butyrate as a result. These metabolites lead to activation of a pathway that is linked to appetite reduction.

Specifically, propionate and acetate bind to a receptor called GPR43, which is found in cells lining our stomach and intestines (7). Activation of GPR43 leads to a cascade of signals eventually triggering the production of GLP-1 and PYY, two hormones involved in inducing satiety.

Naxus has previously been shown to increase propionate levels and GLP-1 production (8). In this current study, it was investigated whether a blend of Naxus® and inulin would positively affect satiety and energy intake.

Methods

In this cross-over study, the authors investigated the effect of inulin + Naxus® on 20 healthy adult males aged between 22 and 55 with no evidence of metabolic or cardiovascular disease.

Each participant took part in both control and intervention conditions, each lasting 21 days. Both the treatment and control groups had to drink two sachets of dry powder dissolved in 150 ml of water daily for 21 days. Therefore, the participants consumed the intervention (or the control) sachet for 21 days following a 14-day period washout, and afterwards the control (or the intervention) sachet for an additional 21 days. The intervention sachet contained 2 g of Naxus® and 2 g inulin, whereas the control sachet contained 4 g of maltodextrin.

After a 14-day wash-out period, participants switched to the other drink for another 21 days. The study comprised 4 visits to assess the participants’ perceived satiety and appetite, the energy intake in an ad libitum meal, faecal SCFA concentration, and the faecal microbiota composition.

Results

Appetite control and calorie intake

The study found that the mean energy intake in an ad libitum meal were significantly lower during the treatment period (838 kcal) compared to the control period (1023 kcal) (p<0.05).

Surprisingly, no changes in self-reported appetite were found. This difference between self-reported appetite and actual calorie intake is common in studies involving prebiotics, which is why measuring actual food intake provides a more objective measure.

Naxus and Inulin results on kcal intake

Microbial composition

Significant changes in the microbial composition of fecal samples were noted, showing noteworthy increases in the abundance of Bifidobacteria (p = 0.035), Lactobacilli (p = 0.061), and Propionibacteria (p = 0.02).

Short-chain fatty acids

Moreover, these changes were accompanied by an elevation in the concentration of short-chain fatty acids (SCFAs), which are known to be associated with gut health. More specifically, an increase of acetate in the faeces sample was reported after 21 days (p=0.02). Acetate has the ability to independently influence appetite, which may explain why the participants consumed fewer calories during a single meal.

The hypothesized increase in propionate levels in the faeces sample was only minimal and not statistically significant (p=0.07). However, it is important to note that faecal propionate concentration alone does not reflect the absorption by the body. Additionally, the signals of propionate in the liver and bloodstream, which were not measured in this study, could potentially have a more significant impact on appetite regulation.

Triple effect

Overall, the results show that the chronic consumption of a blend of inulin and Naxus® leads to a reduction in energy intake, an increase in faecal SCFA concentrations, and an increase in beneficial gut bacteria.

Conclusion

This research indicates that a combination of inulin and Naxus® has positive effects on gut health and confirms existing data that Naxus® positively influences appetite control.

This publication also emphasizes the importance of new studies focusing on the effect of Naxus® on enhancing and tailoring nutritional products to promote satiety and help weight management.

New publication demonstrates potential of Naxus® for alleviating IBD through gut microbiota alterations and increased butyrate production in mice

New publication demonstrates potential of Naxus® for alleviating IBD through gut microbiota alterations and increased butyrate production in mice

Maastricht, The Netherlands, 1st May 2023

Press release
In the present study published in Molecules, the leading international, peer-reviewed, open-access journal of chemistry, the authors evaluated the potential positive effects of arabinoxylans (AX) contained in Naxus® on T-cell-dependent colitis. The findings of the study showed that Naxus® was able to induce peripherally induced Treg (pTreg) cells in the colon. This resulted in a reduction of T-cell-dependent chronic colitis due to the increased levels of butyrate-producing bacteria and luminal butyrate levels. These findings implicate that there could be a role for Naxus® in the treatment of inflammatory bowel disease.

study-wheat-arabinoxylans-on-the-gut-microbiota

Naxus®: a product researched and developed by BioActor

NAXUS®, an arabinoxylan extract obtained from the endosperm of wheat and is known for its beneficial health effects.

Wheat arabinoxylans (AX) are, in turn, a type of non-starch polysaccharide found in the cell walls of wheat grains. AXs are typically composed of a linear β (1-4)-linked xylan backbone with side residues of a-1-arabinofuranose units attached via α-(1-3) and/or α-(1-2) linkage.

Several clinical studies have shown that Naxus® is a powerful and well-tolerated prebiotic which induces a positive effect on the immune system and blood sugar levels by modulating the microbiome composition and Short Chain Fatty Acids (SCFA) production.

Effect of Naxus® on the Gut Microbiota Composition and Colonic Regulatory T Cells: in vitro and in vivo study

Introduction

The study was conducted by the group of Seita Chudan and the groups’ aim was to to understand the effect of wheat-derived arabinoxylan on gut microbiota, colonic regulatory T cells (Tregs) which are a specific subset of T cells that suppresses the immune response, and experimental colitis, this way, discussing the importance of a healthy gut microbiota and its connection to immune function and disease.

Many studies have looked at how AXs from wheat affect the bacteria and compounds in our gut, as well as a type of antibody present in the immune system called Immunoglobulin A (IgA).
However, not many studies have shown how AX might be helpful in treating Inflammatory Bowel Disease (IBD), a condition that is characterized by inflammation of the GI tract. One recent study has looked at how AX might help with a type of IBD called DSS-induced colitis, but it’s still unclear if AX can prevent colitis.

Therefore, it is important to understand how wheat AXs affect the immune system and colitis, particularly in cases caused by the acquired immune system.

Methods

In this study, healthy and chronic colitis model mice were fed with food containing cellulose or Naxus® for 2–6 weeks and subjected to subsequent analysis of the gut microbiota composition and the number of colonic regulatory T cells in both groups.

Results

The results of this study indicate that Naxus® promotes the development of colonic pTregs and helps to reduce T-cell-dependent chronic colitis. The number of colonic regulatory T cells was significantly higher in the Naxus® group compared to the control group. These positive effects may be due to changes in the gut microbiota and increased levels of short-chain fatty acids (SCFAs), especially butyrate.

results-wheat-arabinoxylans-effects-study

Table 1: Quantification of fecal SCFA in mice fed with food containing CE (cellulose) or AX (n = 8)

Butyrate is produced by certain bacteria in the Lachnospiraceae family, such as Eubacterium and Roseburia spp., Increases in Lachnospiraceae bacteria were linked to an increase in fecal butyrate concentration and a greater number of colonic Tregs in the Naxus®-fed mice.

In a T cell transfer model of chronic colitis, Naxus® was found to improve body weight loss and reduce colonic tissue inflammation, possibly through Treg induction. In addition, in this colitis model, wheat-derived arabinoxylan decreased TNFα production from type 1 helper T cells.
Therefore, Naxus® could be a useful prebiotic for preventing colitis by modifying the gut microbiota and shifting the metabolite production more towards butyrate.

Conclusion

This study shows that Naxus® has positive effects in a mouse model of chronic colitis. These improvements are linked to the alterations in the gut microenvironment by regulating the gut microbiota composition and increasing the number of colonic regulatory T cells, which could have implications for the prevention and treatment of inflammatory bowel disease and other immune-related diseases.

Why gut health is key to your overall well-being

Why gut health is key to your overall well-being

April 28th, 2023

Research and professionals often mention that gut health is essential to overall well-being. However, what exactly is meant with the term gut health? How is the gut linked to well-being, and why is this important? In this article, we will explore the gut’s role in the gastrointestinal tract, the gut health, and its role on maintaining a good overall health.

The gut’s role in the gastrointestinal tract

The gut is not only important for the digestion and uptake of nutrients from food, but it also forms one of the most prominent barriers that protect us from many different pathogens.
Intestinal health can also affect mood and cognition through communication between the gut and the brain. The microorganisms that reside in the gut play a major role in how the health of the gut influences well-being.

The gut is also called the gastrointestinal tract or the digestive tract. It consists of the entire pathway from when food first enters the body and the remnants that leave the body again. Along the way, the food gets digested, and nutrients are absorbed to be used as energy sources and building blocks, in order to support the overall physiological functioning of the body.

The intestines are of utmost importance in this process, as this is the site where most digestion and absorption of nutrients takes place.

What is the structure of the gut?

The gut is approximately 9 meters long, with the small intestine taking up 6 meters of this length.
The lining of the gut consists of 4 distinct layers. The villi and microvilli that texture the gut epithelium, increase the surface area at which the absorption of nutrients can take place.
Underneath the outermost layer, blood vessels and lymph vessels are in close proximity to the surface of the gut. This allows for the fast absorption of nutrients into the bloodstream.

The gut contains many cells that are important for immune function. They facilitate the secretion of enzymes and mucus into the lumen, or hormones and other messaging molecules into the blood. The lymphatic system is part of this, as it is home to many immune cells that can fight pathogenic intruders.
A protective mucus layer covers the epithelium, which makes it more difficult for pathogens to pass through.

Gut microbiome

Another important component of the gut are the commensal microorganisms that reside there; the gut microbiota. These microorganisms consist of many different species of bacteria, archaea, viruses, and fungi, and the composition is unique for every person.
Bacteria make up the vast majority of the gut microbiome, with around 1000 different bacterial species that reside in your gut!

The microbes in the gut elicit many important functions. They support energy metabolism, by fermenting otherwise undigestible dietary fibres into short-chain fatty acids (SCFAs). SCFAs can be used as an energy source for intestinal cells, and serve as anti-inflammatory signalling molecules. Read more about SCFAs and their importance to gut health here!
Due to their presence in large quantity, the gut microbiota can oppose colonization by pathogens, stimulate tolerance towards antigens, and induce the production of the protective mucus layer.

What is gut health?

Gut health refers to the overall functioning of the gut, in the absence of symptoms of gastrointestinal distress. The gut microbiome plays a central role in this; there has to be a balance between the helpful and potentially harmful microorganisms in the gut, as this can affect the integrity of the gut. Therefore, crosstalk between these microorganisms and the gut epithelium plays a pivotal role in one’s health status.

There are multiple factors that can affect the composition of the gut microbiota, influencing the function and integrity of the gut barrier. These include environmental factors, including where you live, your age, what you eat, how physically active you are, but also stress levels, and the use of antibiotics, as well as genetic factors.

Why is gut health important?

Immunology

The gut forms a protective barrier against gut microbes, pathogens, food antigens, and toxins to which the body is exposed in the gut. In fact, the intestine forms the largest internal barrier, and is therefore essential for the protections against harmful substances. Next to the physical barrier, as many as 70-80% of the immune cells reside in the gut.

The immune cells in the gut secrete antibodies and antimicrobial proteins. Together with the epithelial and mucus barrier, they protect the underlying tissues form the translocation of pathogens that might be present in the lumen of the gut.

The cells of the gut are held together by so-called tight junctions, which can loosen to become more ‘’leaky’’. On the one hand, this can be beneficial by aiding in the absorption of nutrients, or disposing of the inflammatory stimuli that did manage to cross the gut barrier (diarrhoea).

On the other hand, an excessively leaky gut allows for ‘’bad’’ bacteria and other pathogens to enter the blood stream and cause (chronic) inflammation. This can further increase gut barrier dysfunction and disease. Dysbiosis – an imbalance between the favourable and unfavourable microbes in the gut – are a major cause of a leaky gut. (1, 2)

Gut-brain axis

Gut health is also important for brain health and cognitive function. There is bidirectional communication between the central nervous system – the brain, and the nervous system that resides in the gut. Interestingly, the majority – up to 90% – of the body’s serotonin is produced in the gut. Serotonin is the so-called ‘’feel-good’’ chemical, which plays an important role in the modulation of mood, learning, and memory.

The gut microbiota play an important role in the communication between the gut and the brain. The SCFAs produced by the gut microbiota are able to cross the blood-brain barrier, and directly communicate with the brain. Likewise, dysbiosis of the gut microbiome can alter the blood-brain barrier, possibly contributing to inflammation of the central nervous system, which is linked to depression and anxiety-like disorders (3).

How to support Gut Health?

There are plenty of ways to support gut health. First of all, probiotics can be used to maintain a healthy community of microorganisms, by supplementing directly with live microorganisms. Next to that, prebiotics derived from non-digestible carbohydrates can be used to selectively stimulate the growth of intestinal bacteria. Learn more about prebiotics here!

Another way to enhance gut health is through the use of the bacterial products or metabolites released from microbial fermentation; the so-called postbiotics. In this article, we will tell you more about the use and benefits of postbiotics.

Gut health is the foundation of good health

All in all, it is quite evident that keeping the gut healthy plays is of great importance for one’s overall well-being. This long tract, which is the home to many different microorganisms, takes care of digesting food and absorbing nutrients needed to perform all basic functions. Next to that, it plays crucial role in the defence against pathogens, and through its bidirectional communication with the brain, has a significant impact on mood and cognitive function.

Exploring the ways blood sugar impacts your health

Exploring the ways blood sugar impacts your health

April 20th, 2023

Are you aware that your blood sugar levels can change frequently, and it is important to maintain a stable level in order to improve your overall health? In this article, you will get acquainted with the reason your blood sugar levels might fluctuate, the effects of these changes on your health, and tips to help you on maintaining a stable blood sugar level.

Sugar and blood sugar levels

Sugars and carbohydrates are widely consumed substances across the world. They play a vital role in providing energy to the body and in regulating the blood sugar levels, or blood glucose levels, throughout the day (1).

After a meal, our metabolism works to keep our blood sugar levels steady. It does this by reducing the production of sugar (glucose) and promoting its storage as both short-term and long-term energy reserves (2).

The way your body metabolism responds after eating depends on the type of sugar you consume – simple sugars or complex sugars (1). Foods such as sugar-sweetened foods, beverages, and refined grains are a source of simple sugars, which are associated with higher increases on blood sugar levels.

Sources of complex sugars include minimally processed grains, legumes, and whole fruits. These are considered as a better option to maintain a steady blood sugar level.

When simple sugars and complex sugars are consumed in excess, or under consumed from processed food sources, acute and/or chronic conditions might arise as consequences.

What happens if your blood sugar levels are too high?

We already know that high blood sugar levels might have negative impacts on our health. Stress, some sort of medications, insulin resistance and an unhealthy lifestyle are the core of the increasing of the blood sugar levels (2,3).

Usually, people with higher blood sugar levels tend to experience an increase in feeling thirsty and they have a higher urinating frequency. Experiencing blurred vision, headaches, and fatigue are also symptoms.

On the long term, high blood sugar levels are associated with an increased risk of obesity, type 2 diabetes, heart disease and other organ damages, like nerves, eyes, kidneys, and brain (3).

What happens if your blood sugar levels are too low?

On the other hand, the low blood sugar levels might also have negative impact on your health, occurring when you don’t eat enough carbohydrates according to your nutritional requirements or when the physical exercise is inappropriate in contrast to your food intake (2).

If your body is deprived of having enough fuel to sustain life, the central nervous system won’t be able to synthesize glucose, store, or concentrate glucose from the body circulation (4). As consequence, a brief decrease on the blood sugar levels might cause severe central nervous system dysfunction, and a prolonged decrease might cause cell death and coma.

Commonly, but depending on the severity and duration of the low blood sugar level, people tend to experience shakiness, confusion, irritability, sweating, and a fast heartbeat.

Strategies to maintain a stable blood sugar level

To begin with, it is important to understand what the normal blood sugar levels are. A fasting blood glucose level between 70 and 99 mg/dL is considered normal regardless of some variations caused by diet, physical exercise or medication as mentioned before (12).

When the blood sugar levels are higher or lower than this level some strategies need to be considered:

1. Implementing a healthy diet according to your nutritional needs is one of the strategies to maintain a stable blood sugar levels (5).
Specifically, consuming high in fibre foods such as foods rich in whole grains as source of arabinoxylans seems to be a good adding to a healthy diet along with fruits and vegetables (6). Curious about arabinoxylans? Read our article here.

What’s more? Lean proteins, and healthy fats and limited added sugars consuming are as well associated with better blood sugar control.

2. Physical exercise is an essential part of a comprehensive lifestyle changing (5). Studies have shown that both aerobic and resistance training have positive effects, and that combining the two types of exercise has even more positive effects. This way, combining a healthy eating with physical exercise is crucial on stabilising the blood sugar levels and maintain a healthy weight balance.

Why is it important to keep blood sugar stable?

Summarising, having high blood sugar levels increase the chances of developing obesity, diabetes, and heart disease. On the other hand, having low blood sugar levels can cause problems with cognitive function and other complications. This way, adopting a healthy diet, being physically active, and controlling your weight might helping you on maintaining a stable blood sugar levels and lower the risk of experiencing these adverse health effects.
