Podcast Episode 94: Enzymes and Your Gut

What Are Digestive Enzymes and Why Do They Matter?

Digestive enzymes are proteins that help your body break down food into smaller, absorbable nutrients. Think of them as tiny scissors, slicing large food molecules into pieces your body can use. Without these enzymes, essential nutrients would remain unabsorbed, leaving your body without the fuel it needs ^[4][5][6].

Your body produces a variety of enzymes, each designed for a specific task ^[5]. The pancreas takes the lead in enzyme production, working with the stomach and small intestine to release these crucial proteins ^[2]. Different enzymes focus on specific nutrients: amylase breaks down carbohydrates, protease handles proteins, and lipase breaks down fats ^[4]. The small intestine also produces specialised enzymes, like lactase for digesting lactose and sucrase for breaking down certain sugars ^[2].

When these enzymes are working as they should, they help your body absorb nutrients more effectively, which boosts energy, supports immunity, promotes healthy skin, and even benefits brain function. They also create an environment that encourages the growth of good gut bacteria ^[7]. However, when enzyme production falls short, it can lead to issues like bloating, cramps, and gas ^[6]. Digestive problems are widespread, with around 60 to 70 million people in the United States affected by such conditions, and approximately 75% of adults globally experiencing reduced lactase activity ^[8][9].

As Austin Gastroenterology explains:

"Digestive enzymes play an indispensable role in your gut health. They facilitate the proper breakdown of food, allowing your body to absorb the nutrients it needs in order to function properly." ^[6]

Types of Digestive Enzymes Found in Beer

Beer naturally contains several digestive enzymes, created during the brewing process. Key enzymes include amylases, proteases, and beta-glucanases ^[10].

• Amylases: These enzymes break down starch into smaller components like dextrins, oligosaccharides, maltose, and glucose. In brewing, both alpha-amylase and beta-amylase work together to convert complex starches into simpler sugars ^[10].
• Beta-glucanases: These enzymes help hydrolyse glucans by breaking specific bonds between glucose molecules. This reduces the viscosity of the wort and supports proteases in breaking down starch granules ^[10].
• Proteases: These enzymes break down proteins by hydrolysing peptide bonds, improving protein solubility and reducing the viscosity of the beer. This process is essential for brewing and has been used for over six thousand years ^[10].

These enzymes not only play a crucial role in brewing but also contribute to digestion when beer is consumed.

How Digestive Enzymes Improve Digestion

The enzymes naturally present in beer can aid digestion by breaking down carbohydrates, proteins, and fibre. This process helps reduce digestive discomfort and improves nutrient absorption ^[10].

When you drink beer containing these enzymes, amylases and proteases help break down food components, potentially easing the workload on your body’s own digestive system. This can help alleviate symptoms like bloating and indigestion. Meanwhile, beta-glucanases tackle complex fibres, promoting regular bowel movements and overall digestive comfort. Together, these actions help your body absorb nutrients more effectively, which can lead to better energy levels, a stronger immune system, and improved overall health ^[7].

The Brewing Process and Enzyme Development

The brewing process creates the perfect environment for the development of digestive enzymes. Understanding how these enzymes form during brewing sheds light on why beer, especially when crafted to preserve these enzymes, can offer genuine benefits for gut health.

Enzyme Formation During Malting and Fermentation

Enzyme activation begins with the malting stage. Here, grains like barley are soaked, germinated, and then dried through kilning. This process triggers dormant enzymes within the grain, such as alpha-amylase and beta-amylase, which are essential for breaking down starch into fermentable sugars. Additionally, proteases are activated, breaking down proteins into amino acids that yeast can use during fermentation ^[11][12].

The enzymes produced during malting play a key role in digestion, as many remain active and assist in breaking down complex carbohydrates and proteins once consumed.

Fermentation further enhances enzymatic activity. Yeast generates enzymes like beta-glucosidase, which helps break down complex carbohydrates and polyphenols. Some brewers even incorporate the probiotic yeast strain Saccharomyces boulardii during fermentation. This strain not only survives the brewing process but also produces antimicrobial and immune-supporting metabolites, adding another layer of gut health benefits ^[12].

Temperature and pH control are critical during fermentation to maximise enzyme activity. Brewers typically maintain temperatures of 18–22°C for ales and 7–13°C for lagers, ensuring optimal conditions for yeast performance and enzyme preservation.

Preserving Enzyme Activity in Non-Alcoholic Beers

Maintaining enzyme activity in non-alcoholic beer requires careful processing. Traditional methods of removing alcohol often involve high heat, which can destroy beneficial enzymes. To address this, functional beer producers use gentler techniques to retain enzymatic integrity.

Methods like vacuum distillation, which operates at lower temperatures (40–60°C), and reverse osmosis are commonly employed to remove alcohol without damaging heat-sensitive enzymes ^[11][12].

Some brewers also add enzyme supplements after fermentation to ensure the final product retains its digestive benefits, even if some enzymes are lost during processing. These supplements are carefully introduced under conditions that maintain their activity.

Research supports the effectiveness of these methods. In one study, 68 healthy participants consumed 355 mL of non-alcoholic beer daily for 30 days, resulting in increased gut microbiota diversity, particularly favouring Bacteroides species, which are linked to positive gut health outcomes ^[11].

A great example of this approach is IMPOSSIBREW®, which uses a proprietary brewing process and their unique Social Blend™ to preserve beneficial compounds, including digestive enzymes. Their Enhanced Lager and Enhanced Pale Ale demonstrate how brewing can maintain health-promoting properties while delivering the familiar taste and experience of traditional beer.

The distinction between traditional alcoholic beers and functional non-alcoholic varieties lies in the production focus. While traditional brewing emphasises flavour and alcohol content, functional beer production prioritises the preservation of beneficial biological compounds. This often involves lower processing temperatures, shorter exposure times, and occasionally supplementing with additional enzymes or probiotics to enhance health benefits ^[12].

Gut Health Benefits of Beer-Derived Digestive Enzymes

Beer isn’t just a drink to enjoy with friends; it also contains digestive enzymes that, alongside polyphenols, fibres, and other active compounds, can contribute to a healthier gut. These components work together to support digestion and improve the balance of your gut microbiota.

Your gut is home to an astonishing 100 trillion microorganisms, all playing vital roles in digestion, immunity, and overall well-being ^[1]. The enzymes and compounds in beer can positively influence this ecosystem, helping create a more balanced and thriving gut environment.

Supporting a Healthy Gut Microbiota

Beer-derived digestive enzymes team up with polyphenols and dietary fibres to create an environment that encourages the growth of beneficial gut bacteria. This collaboration not only promotes better digestion but also supports long-term gut health.

Polyphenols in beer play a key role here. They stimulate the growth of gut microbiota, offering anti-inflammatory and antioxidant benefits along the way ^[1]. When gut bacteria break down these polyphenols, they produce short-chain fatty acids (SCFAs), which help to reduce inflammation throughout the digestive system.

In one study, participants consumed 355 ml of beer daily for 30 days. Researchers observed a noticeable increase in the diversity of their gut microbiota, particularly favouring species of the Bacteroides type ^[1]. Importantly, this effect was linked to beer’s polyphenols and was also seen in non-alcoholic beer, which means you can enjoy the gut health benefits without alcohol’s downsides.

Beer also contains dietary fibres such as β-glucans (around 75%) and arabinoxylans (about 20%) ^[1]. These fibres, combined with digestive enzymes, enhance nutrient absorption and breakdown. During fermentation in the gut, these non-digestible carbohydrates feed the microbiota, producing compounds that further aid digestion.

Prebiotic Properties of Non-Alcoholic Beer

Non-alcoholic beer doesn’t just offer enzymatic support - it also acts as a prebiotic, nourishing the good bacteria in your gut. Prebiotics are fibres that bypass digestion in the small intestine and reach the colon intact, where they serve as food for beneficial bacteria ^[15].

Research highlights that non-alcoholic beer encourages a more diverse bacterial population and increases levels of beneficial bacteria like lactobacilli ^[16]. It also triples the bacteria responsible for producing polyphenols and phenolic acids like resveratrol ^[16], which can further enhance your body’s natural defences.

Melanoidins, another compound found in beer, add to these gut health benefits. These substances are poorly digestible, but they bring antioxidant and antibacterial properties that promote a favourable environment for good bacteria while discouraging harmful ones ^[1].

Studies have shown that both alcoholic and non-alcoholic beers improve the diversity of gut microbiota and increase the activity of enzymes that protect the gut from harmful bacteria ^[3]. Moderate beer consumption has also been linked to higher levels of butyric acid, a short-chain fatty acid that provides energy to colon cells and has anti-inflammatory effects ^[14].

IMPOSSIBREW® takes full advantage of these natural prebiotic benefits in their Enhanced Lager and Enhanced Pale Ale. Their brewing process retains the gut-friendly compounds, ensuring you get the health benefits while enjoying the familiar taste of a quality beer.

Practical Tips for Using Functional Beer to Improve Gut Health

Functional beer can be a helpful addition to your routine if you're looking to support your digestive health. However, timing, portion sizes, and understanding who benefits most are key to making the most of its potential.

Recommended Serving Sizes and Guidelines

Research from 2022 suggests that drinking 330 ml of non-alcoholic beer daily for four weeks can improve gut bacterial diversity ^[13]. This standard bottle size seems to strike the right balance for digestive benefits.

For alcoholic beers, moderation is essential. The NHS advises no more than 14 units of alcohol per week, with a limit of one or two drinks per occasion ^[17]. Dr Federica Amati, a medical scientist at Imperial College London, stresses the importance of moderation:

"I'm very keen to pass on the message that we have to drink very moderately. Have at least three days with no alcohol in your week, and no more than one drink when you do drink." ^[17]

Dr Megan Rossi, a nutrition researcher at King's College London and founder of The Gut Health Doctor, adds:

"When we're talking about any anti-inflammatory benefits for the gut from these darker beers, that becomes pro-inflammatory after about two drinks." ^[17]

For best results, drink functional beer with meals. This can help stimulate digestion by promoting the production of gastrin, gastric acid, and enzymes ^[18][19]. A 330 ml serving with food not only enhances digestive enzyme activity but also reduces the risk of stomach irritation.

Who Can Benefit from Functional Beer?

Functional beer can be particularly helpful for those seeking natural ways to support their digestion. Here’s a closer look at who might benefit:

• People with mild digestive issues: Functional beers can provide enzymatic support and prebiotic fibres that help nourish beneficial gut bacteria.
• Health-conscious drinkers: Non-alcoholic functional beers are a great choice for maintaining gut diversity while enjoying a social drink. Studies show that the gut benefits of non-alcoholic beer don’t rely on alcohol ^[13].
• Those on high-polyphenol diets: Polyphenols, found in fruits, vegetables, and whole grains, are broken down by gut bacteria into anti-inflammatory compounds. Functional beer, especially darker or unfiltered varieties, can complement these diets by providing additional polyphenols ^[17].
• Fans of unfiltered beer: Unfiltered beers retain more polyphenols and beneficial yeast, which may have a stronger positive impact on the gut microbiome ^[13].

Precautions and Considerations

While functional beer can be a great addition to a gut-friendly lifestyle, there are some important precautions to keep in mind:

• Pregnant and breastfeeding women: Avoid alcoholic functional beers entirely and consult a healthcare provider before trying non-alcoholic options.
• Those with digestive conditions: If you have conditions like inflammatory bowel disease, Crohn’s disease, or severe IBS, consult your gastroenterologist before adding functional beer to your diet, as individual reactions may vary.
• People taking medications: If your medication interacts with alcohol, even small amounts could affect its effectiveness. Speak with your GP or pharmacist for advice.
• Individuals with alcohol dependency: Stick to non-alcoholic functional beers, which can offer similar gut health benefits without the risks associated with alcohol.
• Those with gluten sensitivities: Look for gluten-free functional beer options. Brands like IMPOSSIBREW® offer gluten-free varieties, such as their Enhanced Lager and Enhanced Pale Ale, which are tailored to health-conscious consumers.

For those watching their calorie intake, functional beers are often lower in calories than traditional beers. A 330 ml serving fits well into most balanced eating plans, especially when choosing low-calorie options like those from IMPOSSIBREW®.
