Are Digestive Enzymes Necessary For Vegetarians?

5.0 rating based on 178 ratings

Digestive enzymes play a crucial role in breaking down food into its constituent nutrients, making them easier for the body to absorb. For vegans, who rely on plant-based sources of essential nutrients like iron, calcium, and omega-3 fatty acids, healthy digestion is essential. Digestive enzymes are predominantly produced by the pancreas and consist of three major types: Amylase, Protease, and Lipase. Low levels of digestive enzymes can result in a slow digestive process, leading to uncomfortable digestive complaints, especially for beginners adopting a plant-based diet.

Enzymes play an important role in maintaining good gut health and overall health. Essential proteins help with proper digestion, and vegans need more enzymes and acid to extract protein from vegetables, grains, and fruit. If there are no medical issues or established food intolerances, digestive enzyme supplements are not required.

The benefits of digestive enzymes in a vegan diet include enhanced nutrient absorption, reduced digestive discomfort, and improved protein digestion. Chewable tablets and specialist formulas of digestive enzymes are available to support a restricted diet. Vegetarian enzymes from microbial sources provide a broader spectrum of digestive activity working on all main food components, including protein and carbohydrates.

Should vegetarians take digestive enzymes?

The body sometimes doesn’t produce enough digestive enzymes. Low level of digestive enzymes can result in a slow digestive process, leading to uncomfortable digestive complaints, especially for beginners adopting a plant-based diet. Taking digestive enzymes may be the ticket to alleviating gastrointestinal discomfort by helping the body break down larger molecules into more easily absorbed compounds for better gut health.

What are Digestive Enzymes?. Digestive enzymes are compounds produced by the body that help break down the foods we eat for proper digestion and nutrient absorption. There are three types of digestive enzymes:

If the body cannot make enough digestive enzymes, food cannot be digested properly and can lead to digestive complaints. Eating plant-based foods that are high in natural digestive enzymes are needed to help improve overall digestion.

Do vegetarians have healthier guts?

Plant-based diets have gained popularity due to their health and environmental benefits, with studies indicating a link between these diets and a decreased risk of cardiovascular diseases, obesity, and other health issues. A systematic review of human interventions found evidence for short- to moderate-term beneficial effects of plant-based diets versus conventional diets on gut microbiome composition and biochemical and anthropometric measurements in healthy participants, obese, cardiovascular, and rheumatoid arthritis patients. However, contradictory results were observed for Enterobacteriaceae at the family level and Faecalibacterium and Coprococcus at the genus level of gut microbiome composition. The relationship between plant-based diets and the gut microbiome, along with their underlying metabolic and inflammatory effects, remains largely unexplored. More interventional studies are needed to address these questions.

Plant-based diets typically incorporate most or all of the food derived from plant-sourced origins while excluding different combinations of animal products, such as red meat, fish, poultry, eggs, and dairy. Flexitarian or semi-vegetarian diets include a small percentage of meat, dairy, poultry, or seafood into a mainly plant-rich diet, allowing for a more significant percentage of plant products to be incorporated into an individual’s diet without the need to remove existing varieties of food. Pescatarians avoid meat and poultry altogether but consume fish and seafood. Lacto-ovo vegetarian diets include eggs and dairy but exclude meat, fish, poultry, and seafood. Vegans strictly do not consume meat or purchase by-products of animals that involve animal testing or inhuman torture.

Can we live without digestive enzymes?

Digestive enzymes are essential to nutrition and overall good health. They help your body absorb nutrients from the foods you eat. Without them, certain foods can lead to uncomfortable symptoms, food intolerances, or nutritional deficiencies.

Certain GI disorders can lead to a lack of enzymes, but enzyme replacement therapy may be an effective option.

Talk with your doctor about your GI symptoms, potential causes, and whether digestive enzyme replacement is a good choice for you.

How do you tell if you need digestive enzymes?

Symptoms of Digestive Enzyme InsufficiencyBelly pain or cramps. Bloating. Diarrhea. Gas. Oily stools (bowel movements)Unexplained weight loss.

Digestive enzyme supplements have gained popularity for their claims of treating common forms of gut irritation, heartburn and other ailments. But how do digestive enzymes work, and who really needs to add them to their diet? Morgan Denhard, a registered dietitian at Johns Hopkins Medicine, provides the answers you need.

What are digestive enzymes, and what do they do?. Naturally occurring digestive enzymes are proteins that your body makes to break down food and aid digestion. Digestion is the process of using the nutrients found in food to give your body energy, help it grow and perform vital functions.

“When you eat a meal or a snack, digestion begins in the mouth,” explains Denhard. “Our saliva starts breaking down food right away into a form that can be absorbed by the body. There are a lot of different points in the digestive process where enzymes are released and activated.”

Why are digestive enzymes so expensive?

Why are digestive enzymes so expensive?

One of the reasons for the high cost of PERT is that there are very few options, and all the available products are brand-name agents. Gupta noted that clinicians often underprescribe pancreatic enzymes in clinical practice. “Because of this, we wanted to look at what are the estimated out-of-pocket costs for patients directly when they’re prescribed an optimal regimen of pancreatic enzymes,” he said.

Study Details. For their study, Gupta and colleagues assessed PERT costs using the Medicare Part D formulary and pricing files for the first quarter of 2020. Point-of-sale and out-of-pocket costs for each PERT formulation were calculated among Part D stand-alone and Medicare Advantage prescription drug plans.

Costs were then assessed using three scenarios: the standard benefit design, with a $435 deductible and 25% coinsurance after the deductible is met; 25% coinsurance to fill a prescription after the deductible while in the coverage gap until the patient spends $6350 out of pocket; and 5% coinsurance once catastrophic coverage is reached.

Who should avoid digestive enzymes?

If you have a history of liver or gallbladder disease, or stomach ulcers, then you definitely want to consult a physician before taking digestive enzyme supplements.

Digestive enzymes generally don’t pose the risk for severe interactions with other drugs. However, some interactions of digestive enzymes may be possible, including with the drugs Warfarin, miglitol and acarbose.

Warfarin is an anticoagulant drug that inhibits the clotting of blood/the formation of blood clots. Acarbose (Precose) and miglitol (Glyset) are alpha-glucosidase inhibitors (oral anti-diabetes medications). It’s possible that taking these drugs with digestive enzymes may reduce the activity of the medications or enzymes.

In most cases, digestive enzymes do not interact with antibiotics, so both can be taken if necessary.

Do I need enzymes or probiotics?

Do I need enzymes or probiotics?

Digestive enzymes and probiotics are very different and affect gut health in different ways. The two actually complement each other: Digestive enzymes improve the processes of digestion while probiotics keep the digestive environment healthy. Having too little of either one is detrimental to gut health.

Probiotics are living microorganisms, and there are billions of them living in the gut. Often referred to as “good gut bacteria,” probiotics support not only digestion and absorption, but also the immune system and neurotransmitter production, to name a few.

When you consume foods with probiotics like yogurt, sauerkraut, or kimchi, the beneficial bacteria primarily work to prevent an overgrowth of harmful bacteria. Probiotics also support a strong gut barrier to prevent pathogens from entering the blood. Another interesting probiotic function is their role in creating certain vitamins.

Is it bad to take digestive enzymes every day?

Digestive enzymes are generally safe, but not free from risk. So, you should only take digestive enzyme supplements if you have a deficiency. Talk to a healthcare professional to find out if these supplements are an option for you.

Do you really need to take digestive enzymes?

Digestive enzymes are essential to nutrition and overall good health. They help your body absorb nutrients from the foods you eat. Without them, certain foods can lead to uncomfortable symptoms, food intolerances, or nutritional deficiencies.

Is it worth taking digestive enzymes?

A. Digestive enzyme supplements purportedly fix all sorts of abdominal symptoms, including bloating, gas, and bowel irregularity, as well as overall gut health. However, for most people, there’s little evidence that they do any good.

Naturally occurring digestive enzymes help break down food so the body can soak up nutrients. Your mouth, stomach, and small intestine make some digestive enzymes. Still, most come from your pancreas, which floods the small intestine with enzymes when the food arrives there.

The main pancreatic enzymes are lipase, which breaks down fats; amylase, which breaks down carbohydrates; and proteases and peptidases, which break down proteins.

Do vegetarians lose enzymes to digest meat?

No, You Haven’t Lost the Ability to Digest Meat. A common misconception about the vegan diet is that you can no longer digest meat properly, causing you to get sick when you eat it. But eating meat again is easier than you think. You might feel a little “heavier” after eating, especially if you have a large portion. But anyone can reintroduce meat after being vegan. Your body can still digest meat just fine.

The key is to start with lighter meats like chicken and poultry as opposed to a big juicy burger or steak. When you haven’t eaten this type of food for a long time, it can make you feel sick to your stomach. This happens because meat requires more digestive enzymes to break it down compared to plants.

The Best Hacks for Reintroducing Meat. As you start to reintroduce meat after being vegan, here are the best hacks we have for making the process move smoothly – inside and out!

  • Yo just some advice for those with digestive issues. I honestly thought I had every issue under the sun, SIBO, candida, constipation, low stomach Acid, bloating, skin issues, food intolerances etc. While Gojiman is a boss and knows his shit, in regards to digestive issues I think he puts a little too much emphasis on the science and addressing the symptoms instead of the root cause. A plant based diet definitely assisted me but it never fully healed my digestive and other issues I was dealing with even after 8 months on the diet. A lot of people don’t realise that digestive issues and psychological/nervous system related issues go hand in hand. I didn’t think I had any of these issues but it turns out I did. I had all of these symptoms goji man mentions and recommends testing for, but I followed non of that. All I did was began meditating, upped my omega 3 fatty acids (ALA – Flax/chia +flaxseed oil) and worked on my vagal tone (I had a sympathetic dominant nervous system). Following these steps I saw improvement very quickly, and within a few months all my issues were gone, digestion was absolutely great, and the depression/brain fog i didn’t even realise i had is gone. All of these issues slowly began to enter my life after an extended period of stress, and it seems like it changed the way my brain worked. Studies have shown the brain is very malleable (neuroplasticity), and even just after 8 weeks of meditation the brain can physically change and it can even be detected via an MRI.

  • awesome article as always man! My digestion has always been good as a vegan but then I did a 3 week vegan keto experiment and after going back to my regular diet Ive experienced minor digestive issues. thought this would be a good time to get a full analysis on my gut health and thanks to you I know exactly what to do to confirm the state of my gut health with confidence!

  • Hey Simon, hope you’re doing well 🙂 I don’t know if you remember me (one of many of your followers with digestive issues) you recommend me to get tested for SIBO and the results came negative, I also got tested for fructose and it came up with 20 which is slightly intolerant. I eat plenty of fruit and that wasn’t the problem. It’s true I had some issues when having an apple in the afternoon or sometimes with dates (both high in fructose) but actually since I decrease the amount of legumes I’m much better so legumes everyday for me wasn’t good. THANK YOU 🙂

  • #askgojiman I have a question about salt/sodium intake. I hear a lot about SOS free vegan diets, (salt, oil, sugar-free) and do fine without oil and sugar. However, every time I lower my salt/sodium intake, I have massive cravings for months until I end up adding salt back into my diet. Is this from some kind of imbalance or deficiency in sodium, or from the so-called addictive properties in salt? Should we eat salt at all? How much sodium should we consume? Thanks in advance for reading this!

  • #askgojiman Please help me! I have barrettes esophagus and IBS. I went gluten free a year and a half ago. It helped some. I also lost 86 pounds trying to solve my digestive issues. I went plant based vegan a month ago (and absolutely love it) to help my IBS. Meat and dairy were killing my gut. My problem is…I am more bloated now than before. I admit that I do not get all my nutrients because I can not eat beans and a lot of food. I follow the low fodmap and Sibo diet. I am lucky to get 1000 calories in a day. My doctor won’t test for Sibo yet as he thinks I have gastroparesis. He said give it another month and prescribed amitriptyline. My question is how do I stop my stomach bloating and what can I eat to get my protein?

  • #askgojiman I have an overgroth of candida, sibo and bad digestion. I believe I also have a leaky gut, will test for it soon. Should I firstly focus on getting rid of the candida with different cleanses, then fixing my gut and after that stomach acid and lastly bombard my gut with probiotics and prebiotics? I have heard that you shouldnt take pre or probiotics while getting rid of candida/ibis because it can feed the bacteria to much. Please help me, is this a good plan?

  • Hello GojiMan! I love your articles! I have a quenstion for you: recently I found out that I have h. pylori infection and I was put on 3 different types of antibiotics to try to get rid of the bacteria. I am excited because it should clear my skin a bit and also to have better digestion but I watched your articles where you said that you took a heavy dose of antibiotics and it ruined your health. I would like to know what I could do after my antibiotic treatment that would help me to not get in the same trouble as you were in the past. #askgojiman
