What are digestive enzymes, and how do they work?
Learn how digestive enzymes work, how your body breaks down food, and whether you should think about adding digestive enzyme supplements to your wellness routine.

Every time we sit down to eat, our bodies begin the process of changing food into nutrients we can use for energy, repair, and growth. Digestive enzymes are at the center of this process. Residing in the gut, digestive enzymes are vital proteins that work to support digestive health, provide your body with nutrients, and even support a healthy immune system. Here, we'll explore more about digestive enzymes, including how they function, why they're so important for your overall health, and whether it makes more sense to get your digestive enzymes from food or from supplements.
What are digestive enzymes?
Simply put, enzymes are proteins that facilitate chemical reactions. Digestive enzymes are proteins that help the digestive system break down food to give the body energy. These proteins are released at multiple places as food travels through the body. Made by the mouth, stomach, small intestine, and pancreas, digestive enzymes work to break down fats, carbohydrates, and proteins. While the body primarily makes its own digestive enzymes, some can be found in foods, like pineapple, papaya, and fermented foods (like kimchi and sauerkraut).
Most people's bodies make plenty of enzymes for healthy digestion. Certain conditions like cystic fibrosis, pancreatic cancer, gastrointestinal issues, and chronic pancreatitis can inhibit the body's ability to create digestive enzymes. People who have these health conditions may need to take digestive enzyme supplements to support healthy digestion. Many people find they respond well to over-the-counter digestive enzymes, while others require prescription digestive enzyme replacement therapy known as pancreatic enzyme replacement therapy, or PERT.
The body releases a number of digestive enzymes throughout the digestive process, including:
- Amylase: This enzyme is vital for digesting carbohydrates, as it breaks starches down to sugars.
- Maltase: This enzyme converts malt sugar into glucose, which can be used immediately or stored in the liver for use at another time.
- Lactase: If you're lactose intolerant, your body likely does not produce enough lactase. This enzyme breaks down lactose, a simple sugar found in milk.
- Lipase: This enzyme helps to break down fatty acids (like those found in fish).
- Proteases: This group of digestive enzymes works to break protein down into amino acids, and supports immune function, blood clotting, cell division, and more.
- Sucrase: This enzyme converts sucrose into fructose and glucose, which are easier for the body to absorb and use for quick energy.
How do digestive enzymes function?
When you eat, digestion begins immediately. As you chew, a digestive enzyme in saliva—amylase—begins to break starches in your food down into simple sugars, providing the body with a quick source of energy as your food continues to move through your digestive system.
After you swallow your food, protease enzymes in the stomach begin to break down protein. Food then moves into the small intestine, where it encounters digestive enzymes released by the pancreas, including lipase, amylase, and more protease. These enzymes work together to further break down carbohydrates, proteins, and fats. Lactase is also released in the small intestine. These nutrients are then absorbed into the bloodstream through the lining of the small intestine, where they're used as energy throughout the body.
Signs that you may have a digestive enzyme insufficiency
As we mentioned, certain health issues—especially issues that affect the pancreas—can make it harder for your body to make enough digestive enzymes to properly support the digestive process.
Signs of digestive enzyme insufficiency can include:
- Unexplained weight loss
- Oily bowel movements
- Constipation
- Unexplained, ongoing abdominal pain or cramping
- Bloating
- Diarrhea
- Persistent gas
If you notice that you have these symptoms continually, it's a good idea to talk with your doctor. While some of these symptoms could simply be signs you need to make some dietary changes, they could also be indicative of a serious health condition, like diverticulitis or pancreatic problems. Left untreated, digestive enzyme insufficiency can result in serious health problems, including malnutrition.
Supplements vs. food: what's the best choice?
There's little research to suggest the digestive enzymes contained in certain foods (like pineapples and avocados) do much to aid digestion. Instead of trying to load up on enzyme-rich foods, it's a better idea to cut processed foods from your diet and add in fiber-rich fruits and vegetables to support healthy digestion.
If you're experiencing symptoms of a digestive enzyme deficiency and believe you may need digestive enzyme supplementation, talk with your doctor. Some simple digestive enzyme issues (like lactose intolerance) are easily treated with over-the-counter digestive enzymes. Your doctor can help to guide you in the right direction if you need additional enzymes, or can recommend further testing to rule out serious digestive issues.
Are digestive enzymes and probiotics the same thing?
While both are important for digestion, digestive enzymes and probiotics are not the same thing. Digestive enzymes are proteins that facilitate chemical reactions that allow the body to get energy, while probiotics are live microorganisms that live in the gut and help to maintain a healthy balance of bacteria throughout the digestive system. You can (and should!) eat foods rich in probiotics (like yogurt and kefir) to support a healthy digestive system.

Behind the Behaviorgram
Behaviorgrams help us put data into context and extract additional insights from it. For example, we can more easily analyze how heart rate changes when people are in a workout session, or the effect that talking on the phone has on walking pace.
Learn What a Behaviorgram Is and How It Works
We have a talented team of data scientists and researchers focused on providing individuals the opportunity to participate in cutting edge research. When our members participate in research, the activity data that they consent for use in the research helps our team study a number of health behaviors — everything from how to measure chronic pain to better understanding the individual migraine experience.
Analyzing and contextualizing the behaviors of thousands of participants with millions of data points is not an easy task. Over the years, this analysis lead to the creation of something that we have internally named “behaviorgram”. The behaviorgram of a person is a collection of their data streams over the course of some time. A behaviorgram can be quite simple and consist of only a few data streams from a single device (such as heart rate and steps from an activity tracker) or it can be quite large and include multiple data streams from multiple sources. A behaviorgram can be visualized much like an ECG, and below, we provide a glimpse as to what this visual may look like.
In our studies, we may start with activity data from a Fitbit or Apple Watch and then layer on additional data such as survey responses (e.g., mood or feelings during the day) and contextual information (e.g., weather, air quality, and the time of the day). Dense behaviorgrams give us richer pictures of someone’s behavior over time. As a reference, the behaviorgrams we created for the research on Alzheimer’s disease we did with Eli Lilly and Apple in August contained dozens of data streams and included steps counts, walking pace, sleep depth, workout sessions, and many others.
Behaviorgrams help us put data into context and extract additional insights from it. For example, we can more easily analyze how heart rate changes when people are in a workout session, or the effect that talking on the phone has on walking pace. It also allows us to derive new data channels from the existing ones. For instance, while MyFitnessPal already reports how many grams of protein and calories are eaten, we often find it useful to layer in a channel that represents the percentage of calories that came from protein. Similarly, we often add a new data stream that represents heart rate during periods of inactivity (i.e., no steps).


What would actually help you visualize a behaviorgram? A picture of course! We wanted to illustrate that there are small moments throughout your daily life that can have a significant impact on your health, and we were fortunate enough to get consent to share one of our colleague’s visual health journey via the various apps they have connected on Evidation. Looking at their data from the last 6 months, we tracked down a few key dates where we noticed specific behavior changes and asked them to add labels to the behaviorgram on what happened in their life on those days. Sure enough — in a week with less sleep, we uncovered they were abroad, working until late to match California time and then having troubles falling asleep due to jet lag and an uncooperative baby. You can see other activity trends like sightseeing with friends in Singapore and New York on high steps count days, frequent awakenings in sleep during a night spent on an international flight, and a spike in logged calories when they had leftover sweets for breakfast. You can also see that they were able to sleep longer when the baby was away with the grandmother. We got a good laugh out of the observation that the company offsite was a high fat/protein-heavy day!
Based on weather data, the highest precipitation day is low in activity! Though some of our team is based in sunny locations, it highlights that weather does impact our activity. Related, given the air quality impact that the Wildfires had in California this year, you can see that during the time of the fires 11/25 to 12/14, they did not spend much time outside and took some time off from exercising (with the exception of their time in New York!)
Keep an eye out for more references to behaviorgrams from us! Our hope is that they’ll begin to become a tool by which you contextualize different actions that you take. We also know that big life changes can impact your habits and health. That’s why we’re planning on sharing some personal stories from our team on the journey to being a new parent and its impact on health routine. We also want to capture events like life with a newborn to highlight trends that our specific team members are experiencing to show activity patterns during the first few months of these very significant milestones.

Evidation Member Stories
No matter where you are in your health journey, we want to commend you for taking steps to become a better version of you.
We’re back to share more about the growing community of Evidation Members. No matter where you are in your health journey, we want to commend you for taking steps to become a better version of you. Over the last year, we’ve asked members to share their stories with us. Since then, we’ve received more than 160,000 stories! Here’s a look at some of the many stories members have shared — hopefully one of them will help inspire you as they’ve inspired us.
Whether you’re looking for a source of motivation, a community to learn from, or are here for a few extra bucks, we’re happy to be a part of your journey! Here’s another look at some of your fellow Evidation Members and their stories:
“A friend told me about Evidation which I’ve been using for quite a while. It gives me credit for my daily exercise, weigh-ins and tracking my food which I do daily. It helps keep me in the zone and best of all has paid me for my efforts! What’s better than that? I just had a Grand Opening in Oceanside, NY for my business, Restorative Wellness and Weight Loss. I plan to share this app with all my clients. What a great motivator!” — (Wendy C., New York)
“I have been a part of a research study on breakthrough pain through Evidation, and it’s really helped me to be more aware of my body and what kind of triggers are causing my pain. It has also caused me to look into other ways of relieving my pain, such as yoga and deep stretching, and to gain some muscular structure back that I had lost before.” — (Stacy M., Tennessee)
%2520(1)%2520(1).png)
“I have been using Evidation to help me stay on top of my health and fitness. I have a busy schedule and it’s hard to stay on top of things. In 2016, I was 227 lbs, very depressed and unhappy. After making several lifestyle changes, I have gotten down to 166lbs and maintained that since 2018. Evidation helps me stay on top of why health by keeping me accountable.” — (Nicole M., California)
“Through the research projects and daily accountability, Evidation has supported my increased health outcomes. By participating in a chronic pain study, daily loggings have helped my provider and I to track some of the triggers that have affected my pain levels. Additionally, being accountable to the overall app gives me motivation to get outside my comfort zone and get out and move even when I am not physically feeling like it.” — (Karen K., Colorado)
%2520(1).png)
“Using Evidation really helped me during a time of my life when I was down. We moved from my hometown and I was so sad, depressed, and motivated. I was in a funk, I felt lost, and did not want to leave my house. No friends or close family. When I started my health journey I got out of the house to attend group exercise and made friends. Not only did I have an online community cheering me on, I stepped out of my comfort zone again and felt like a better version of myself. Thanks for keeping me accountable!” — (Christina W., Texas)
%2520(1).png)
“I have been using the Evidation App for a few years now and I love how I build points for demonstrating regular and consistent healthy practices. As a Tour Director and Travel Professional, it’s great to know that regardless of the activity or destination I may be in there is still an app that will incentivize me to staying fit. Through the use of this app, I have been able to climb the Great Wall of China, hike Machu Picchu, Swim between Thailand islands, and walk on African Safaris. Thank you Evidation for making this app user friendly, simple, and personable.” — (Justin C., Arizona)
%2520(1).png)
“I am 64 years old. I want to be a future fun Grandpa and with the support of Evidation, I will be able physically as well as emotionally to prepare for my next adventure. This is why I hike and walked so much.” — (Rusty L., Indiana)
%2520(1).png)
“The Evidation App has allowed me to accurately track certain aspects of my health and fitness activities, which allows me to create better habits. Seeing my progress and stats turn into points both extrinsically and intrinsically rewards me. This part of the app, as well as reading interesting health studies has huge, positive impacts for future health gains.” — (Kathleen E., Florida)
“From looking at my lifestyle, my health wasn’t what I need it to be. Evidation helps me create a goal for me to challenge myself to get active and to be more involved with the local area. I have been going out for walks, participate in a gym, and being more aware of the foods I eat. With a group of friends, it becomes a fun activity! In a way, I hope my choice in exercise also inspire others to participate in fitness.” — (Hanh N., Arkansas)
%2520(1).png)
“I have been using Evidation for a while now, and the motivation and support I get from this app is unparalleled! It’s a constant reminder to get up and get moving, practice my yoga and meditation, and be that vibrant example of a holistic, balanced life for my daughter. The surveys and app functionality are a fun touch, too!” — (Meggie C., Idaho)

Here’s to our Heart Healthy Members!
This February, in honor of Heart Health Awareness Month, we partnered with our data science team to look at patterns of some of our heart healthiest members.
This February, in honor of Heart Health Awareness Month, we partnered with the data science team at Evidation to look at patterns of some of our heart healthiest members.
Resting heart rate (your pulse rate while awake, relaxed, and stationary) has been shown in several large epidemiologic studies to be an independent predictor of cardiovascular disease and all-cause mortality in both men and women. Given the importance of resting heart rate for heart and overall health, the team looked at all of the Evidation Members who contributed resting heart rate data in 2018. We explored the trajectory of resting heart rate from week to week and selected a handful of members that significantly dropped their resting heart rate over the year. The individuals we selected had a wide range of resting heart rates to begin the year.
Of the members we selected, 96% were within the normal range of 60–100 beats per minute. According to the Harvard Health blog, “while a heart rate is considered normal if the rate is between 60 and 100 beats per minute, most healthy relaxed adults have a resting heart rate below 90 beats per minute.” Only 4% had resting heart rates below 60 beats per minute at the beginning of the year. Resting heart rates below 60 bpm are often indicative of people who get a lot of physical activity. Near the end of the year, over 30% had reduced their resting heart rate to 60 beats per minute or lower. Overall, we observed an average drop of 11 beats per minute, which corresponds to an average decrease of 15% from the beginning of the year.

We then asked these resting heart rate improvers to tell us a little bit more about what they did in order to better understand their habits throughout the year — everything from how often they checked their heart rate, to the frequency of their workouts, to dietary changes they had made throughout 2018.
Here’s what we found!
Most members who had a significant decrease in resting heart rate in 2018 also noticed the same thing!

Most of our heart healthy members said they checked their resting heart rate frequently — if not every day, then at least a few days per week.

The most common changes that Evidation Members made to their diet included the following:
- Adjusting their portion sizes
- Limiting consumption of fast food
- Consuming more vegetables and fruit

The most common types of physical activity included:
- Walking
- Lifting weights
- Running
- Hiking
- Yoga

When we took a closer look at activity data, we actually saw an increase of 871 steps per day (12.3% increase) for members who had lowered their heart rate. Those who responded that they did more walking in 2018 truly did up their step count.

___________________________________________________________________
Evidation Members overwhelmingly said that they had lost weight, made changes to their diet, exercised more often and regularly, and focused on maintaining a healthy weight when sharing some of the changes that they made to their lifestyle in 2018.
In fact, when we took a look at weight tracking for our heart healthy members, the data matched up with the responses. For those who tracked their weight at least once per week for 30 weeks or more, the average weight loss was 12 pounds (a 6% decrease on average).


Not surprisingly, mental health and improved sleep can significantly influence an individual’s overall quality of health. Did you know that sticking to a sleep schedule can help you improve your heart health?

Our community of heart healthy members have recommended to others the value of maintaining a healthy diet, exercising more, and managing stress as tips to improve heart health.

The Big Picture: Are Evidation Members’ Data Scientifically Valid?
Our scientists analyzed activity and sleep metrics from more than 600 members using a global health assessment tool to assign scores for physical and mental health measures.
You use Evidation to conveniently monitor progress toward personal health goals. By making datasets available to scientists, Evidation also is helping uncover insights to benefit people with multiple sclerosis, chronic pain, and other conditions. So, it’s important for you and researchers alike to know that Evidation's quality of life measures stand up.
Prior research conducted with activity trackers has shown that some behaviors (such as inconsistent sleep patterns) are associated with lower levels of physical and mental well-being. While this seems logical, we wanted to see if data collected via Evidation’s unobtrusive, hands-free methods have the same correlations.
Our scientists analyzed activity and sleep metrics from more than 600 Evidation Members using a global health assessment tool to assign scores for physical and mental health measures. (Controls included age, sex, race, socioeconomic status, and medical markers of anxiety and depression.) The 600 members involved in this analysis included members who had self reported having anxiety and depression and were a part of the Mental Health Study.
In this analysis of activity and sleep metrics, here’s what our researchers found:
- Two-thirds of members who participated in this study had scores above the median level for both physical and mental health. One-third scored below the median.
- Those with higher scores were more physically active, walking an average of 1,674 more steps and burning 100 more calories daily than those with scores below the median level.
- Individuals with lower scores demonstrated less consistent sleep than those with scores above the median.
The conclusion? Passive apps where most information is collected automatically can accurately characterize key quality of life metrics — good news for you and for scientists.
An ongoing, year-long study continues to examine a subset of member activity and sleep data, plus self-reported quality of life, mental health, and use of health care resources. Stay tuned as we share more on these findings, plus future research participation opportunities.
