How Plant Enzymes can Help you Feel Better

As I’ve delved more into the world of food pharmacology (food as medicine), I’ve come to realize how important proper digestion is to health, particularly for those of us managing Chronic Disease conditions. People with Chronic Disease usually experience some level of nutrient deficiencies, food sensitivities, digestive issues, and infections. These symptoms are often caused by a diminished ability to absorb proper nutrients from the food we eat.
This is where digestive enzymes that help the body break down food, can be a critical tool for improving digestive health, boosting nutrient uptake, and reducing the symptoms of Chronic Disease.
What type of enzymes are best to take?
The answer depends on the symptoms you are experiencing, and the types of foods that are problematic for you. There are five types of digestive enzymes that are helpful for Chronic Disease — in this week’s article, I will focus on vegetable digestive enzymes, which are used primarily after the consumption of vegetables, especially those that may be difficult to digest due to their high starch and fiber content.

The Gut and Chronic Disease
In the world of functional medicine, we often refer to the concept that all disease (and thereby all healing) begins in the gut. The gut performs the all-important role of digesting and absorbing the nutrients we take in. I like to say, “You are what you absorb.”
In a well-functioning gut, the body produces the appropriate enzymes to break down the food that is ingested. Enzymes, such as amylase and maltase, begin their work in the mouth as food is chewed. Further enzymes, such as lipase and lactase, are released by the stomach, pancreas, and small intestine to break down the food particles as they move through the digestive tract so that they can be absorbed by the body.
However, compromised intestinal function is almost always a factor in people with Chronic Disease, and oftentimes, the root cause of their thyroid condition.
When the intestinal walls become damaged due to a variety of possible culprits, including high levels of stress, toxins, infections, a deficiency in enzymes, and food sensitivities, the body becomes unable to absorb nutrients, due to the intestines’ inability to break down certain foods. Not only will a person become lacking in key nutrients, but those undigested food particles may damage the intestinal lining, causing or exacerbating intestinal permeability, or leaky gut syndrome (a precursor to autoimmunity).
When toxic substances permeate the intestinal lining and become absorbed into the bloodstream, the body may recognize them as foreign invaders. This causes inflammation in the body as it begins to attack the intruders, and eventually leads to autoimmunity.
When food particles are poorly digested, we are also more likely to become sensitive to them. People with Hashimoto’s are particularly prone to be sensitive to gluten, dairy, and soy because these proteins are among the most difficult to digest and are also the most commonly eaten proteins in the Standard American Diet.
When someone ingests foods that they are sensitive to, they will develop IgG antibodies, (which are the same types of antibodies that target the thyroid gland in autoimmune disease), towards these foods. With regular consumption, the immune system attack becomes up-regulated as the influx of poorly digested foods triggers the immune system to make more of these types of antibodies.
Additionally, the poorly digested foods will continue to feed the potentially problematic bacteria that live in the gut. (An overgrowth of opportunistic bacteria has been linked to autoimmunity!)
That said, there are ways to improve one’s digestion. Supplementing with the proper digestive enzymes can aid the body in digesting food, thereby increasing nutrient absorption and boosting gut health. In fact, a 2008 study published in the Alternative Medicine Review found that supplementing with enzymes provided a safe and effective treatment for various digestive issues, including lactose intolerance, celiac disease, and other digestive malabsorption disorders.
There are five types of enzymes that may be beneficial:

  • Protein digestive enzymes
  • Systemic enzymes
  • Fat digestive enzymes
  • Vegetable digestive enzymes
  • Gluten/dairy digestive enzymes

Again, this article will be focusing specifically on vegetable digestive enzymes.
Vegetables and Digestion
We all know how important it is to eat our vegetables. In fact, many of my recommendations for healing the body through nutrient-dense whole foods, revolve around fueling the body with nourishing green vegetables. But for some people with Chronic Disese, a damaged gut and a lack of digestive enzymes can make vegetables difficult to digest, as their high fiber and starch content may be difficult to break down, especially in their raw form.
A 2009 study published in the World Journal of Gastroenterology found that conditions related to thyroid abnormalities, including both hyper and hypothyroidism, can be associated with digestive issues. While all the mechanisms and causes behind these digestive issues are not completely understood at this time, researchers have found that hypothyroidism can delay gastric emptying, and severe cases may lead to disturbances in esophageal peristalsis (which causes large pieces of digested food to be rapidly pushed toward the esophagus by the pharyngeal constrictor muscles). Given that up to 15 percent of hypothyroid patients have fewer than 3 bowel movements weekly, the study emphasizes the need for practitioners to recognize that digestive issues can be related to Chronic Disease conditions.
In some cases of Chronic Disease, an indigestible ball of plant fiber material known as a phytobezoar, which is formed out of undigested vegetable fibers, has been found to cause bowel obstruction. These masses of undigested material commonly consist of vegetable fibers from pulpy fruits, orange pits, seeds, roots, and leaves, but can be formed from any indigestible food fibers. Fibrous foods that are often found in phytobezoars include celery, pumpkin, prunes, raisins, leeks, beets, persimmons, and sunflower-seed shells. Gross, right?
A 2018 study in the Journal of Surgery Case Reports documented an 11 year-old boy who was admitted to the hospital for a bowel obstruction and subsequent surgery to remove the mass from his small intestine. After examining the mass and questioning the boy, it was discovered that he had eaten a large quantity of oranges, including the membrane, a few days earlier. This had caused the mass of undigested fruit fiber to form in his intestines. The authors of the study noted the importance of avoiding large amounts of plant fibers and chewing food thoroughly! While the boy was not noted to have a chronic condition condition, this study highlights the importance of proper fruit and veggie digestion.
Interestingly, insoluble fibers, which are high in vegetables like leafy greens, corn, celery, and bell peppers, have been shown to mechanically trigger symptoms of irritable bowel syndrome (IBS) as they move through the digestive tract. However, certain fibers — particularly soluble fiber such as psyllium — may actually be a helpful treatment for IBS. So perhaps the inability to digest the insoluble fibers is due to an enzyme deficiency, further contributing to the autoimmune cascade and IBS symptoms.
Symptoms of Poor Veggie Digestion
Common symptoms of poor veggie digestion include bloating, gas, constipation, and stomach pain. Symptoms of nutrient depletions that may occur when the body is unable to break down and absorb the nutrients in fibrous vegetables, are much further reaching and may include fatigue, hair loss, muscle pain, and autoimmunity itself.
Deficiencies in antioxidants such as vitamin C (which is found in high amounts in cruciferous vegetables, bell peppers, and leafy greens), vitamin E (Annatto-E by Designs for Health), beta-carotene (a vitamin A precursor), and the minerals selenium and manganese, often result due to poor vegetable digestion.
Folate is another important nutrient that can become depleted when vegetables aren’t properly absorbed. Common sources of folate include broccoli, asparagus, avocado, spinach, and Brussels sprouts. Getting enough folate from food sources is particularly important for those with the MTHFR gene variation, and can become challenging when veggie digestion is compromised.
Another clue that vegetables are not being properly digested is when vegetable fibers are found in stool samples. My collegues used to ask this question of their clients, but never did formal tracking, so out of curiosity, I asked my collegues to ask their clients via a survey about digestive health. Ninety-eight people answered the survey, and 82 percent of the clients that they surveyed stated that they had visible plant fibers in their stool. (While this can be easily seen with the naked eye, it can also be confirmed more objectively through stool testing, such as the GI-MAP by Diagnostic Solutions. 
Solutions for Vegetable Digestion
I’d like to share some strategies to help you overcome veggie digestion issues so that you can help your gut heal, eliminate your symptoms, and prevent nutrient depletions.
Tips to Make Foods Easier to Digest
As I mentioned earlier, due to their high fiber content, vegetables tend to be the most difficult to digest when in raw form. However, there are ways of preparing vegetables that may help with digestion and nutrient absorption:

  • Cook raw vegetables – Raw fruits and vegetables can be difficult to digest if you have a leaky gut, which is why you may need to focus on eating well-cooked foods in the early stages of intestinal healing. The process of heating and/or puréeing vegetables softens some of the tough fibers, rendering them more easily absorbed. (It also breaks down the goitrogenic potential of cruciferous vegetables) Once these are tolerated, you can try to work your way back to raw vegetables with the peel. Start by adding in some raw, peeled and puréed vegetables, then progress to raw peeled fruits and vegetables, and eventually try the unpeeled variety. As you begin reintroducing raw fruits and veggies, you may benefit from vegetable-digesting enzymes, which we’ll discuss in a minute.
  • Chew thoroughly – Enzymes are present in the mouth, and the act of chewing food begins the process of breaking it down so it can be absorbed by the gut further down the line.
  • Drink smoothies or vegetable juice – By blending or juicing the vegetables, the fibers are broken down or extracted for easier digestion.
  • Consume fermented vegetables – The fermentation process is similar to how the body digests food, so these foods are essentially “predigested” and more readily absorbed. Fermented foods are an excellent way to promote gut healing, as the probiotics that are produced during the fermentation process can be beneficial in balancing your intestinal flora, and can help with symptoms of constipation, digestion and anxiety. Some of my favorite fermented foods include sauerkraut, kimchi, and coconut kefir. (Note: If you have SIBO, fermented foods may exacerbate your symptoms.)
  • Include digestive bitters – These bitter medicinal herbs can include any combination of herbs, roots, bark, fruit, seeds, and flowers from botanical sources. They are defined by their bitter flavor and include a wide variety of plants, including dandelion, burdock, gentian, artichoke, chamomile, milk thistle, motherwort, and goldenseal. By stimulating the bitter receptors in our mouth, tongue, stomach, gut, liver, and pancreas, bitters promote healthy digestion by increasing digestive secretions. This leads to better absorption of nutrients and natural detoxification of the liver. Bitters are often taken in tincture form, but another easy way to include them in your meals is to add dandelion leaves, arugula, or radicchio (or any bitter-tasting veggies!) to your salad or smoothie.

Supplementing with Veggie Enzymes
For those who experience bloating and abdominal discomfort after consuming vegetables, or who have noticed undigested vegetable fibers in their stool, a vegetable digestive enzyme that contains fiber-digesting enzymes may help you feel better.
Enzymes commonly used to help break down vegetables for better digestion include:

  • Cellulase, an enzyme that converts cellulose into glucose, is essential for breaking down vegetables, but it’s not naturally produced by the body.
  • Amylase breaks down starches to help the body digest starchy and fibrous foods like raw veggies and fruits.
  • Diastase, an enzyme that can be found in malt and raw honey, works to break down starches and turn them into glucose for absorption.
  • Glucoamylase breaks down the starches in vegetables, rendering them absorbable by the body.
  • Alpha-Galactosidase breaks down sugars in complex carbohydrates to relieve intestinal gas and bloating.
  • Hemicellulase breaks down hemicellulose, a type of cellulase and component of the cell wall in all plants.
  • Invertase catalyzes the breakdown of sucrose (table sugar), especially in high-sugar containing vegetables like corn and beets, which are then converted into fructose and glucose.

Taking these types of enzymes may help reduce gas, bloating, and constipation after vegetable-heavy meals.
Designs for Health formulated the Plant Enzyme Digestive Formula supplement with a specific combination of enzymes, including cellulase and amylase, to help with this process. It also contains the enzymes protease, lactase, lipase, and phytase to help break down proteins, grains, and fats for optimal digestion.
I recommend taking one capsule with every meal that is high in vegetables — but be sure to consult with your practitioner before starting them to tailor the dosage to your individual needs.
The Takeaway
Getting to the bottom of your own digestive issues can take some time and perseverance, but it is a crucial step toward recovering from Chronic Disease. Veggie enzymes have many benefits that can help to relieve many of the symptoms that are experienced with Chronic Disease, such as constipation, gas, bloating, and abdominal pain. As a bonus, improving one’s absorption of veggies can help increase their absorption of vitamins and minerals and, in turn, address underlying nutrient deficiencies.
If you are experiencing bloating, gas or abdominal pain when you consume fibrous vegetables, supplementing with a veggie enzyme formula (like the Plant Enzyme Digestive Formula) could help you boost your nutrient absorption and allow you to enjoy that spinach salad!
For issues with low stomach acid, I invite you to take a look at my article about the benefits of betaine with pepsin. I’ve also written an article that covers other types of enzymes that you may find beneficial in addressing digestive difficulties that are often times present with Chronic Disease.
As always, I wish you well on your journey to feeling your best!
