Are Digestive Enzymes Important?
People nowadays are so focused on what we eat, but what about how we digest and metabolize food? Most of us have a general idea of what digestive enzymes are, but not many have considered the scope of their importance and the role they play for overall health.
What They Are and What They Do
Digestion doesn’t just take place in your stomach. The pancreas produces a large portion of your digestive enzymes, as do the small intestine, stomach lining, liver, and salivary glands[i] (digestion begins in the mouth, after all). But these enzymes do not digest food - they digest molecules (aka nutrients).
Digestive enzymes are the catalysts responsible for breaking down food into molecules to extract nutrients. They are then converted into:
Amino acids from proteins
Fatty acids and cholesterol from fats
Simple and complex sugars from carbohydrates, and,
Essential vitamins, minerals, and compounds.[ii]
This process is by no means a simple input-output. Dozens of different enzymes work together along the gastrointestinal (GI) tract to break down macronutrients from the foods you eat. These nutrients are sent through the bloodstream to the liver and then are absorbed into the lymphatic system, which distributes them to tissues, organs, and muscles.[iii]
As you can imagine, this complex exchange is responsible for the body’s access to fuel and hydration. But it doesn’t end there. Digestive enzymes affect factors for daily life that are not often considered.
You can eat all the healthy food in the world, but if you can’t absorb it, not even the healthiest of diets will do any good. However, our bodies can only digest what it’s given. High-fiber foods such as fruits and vegetables contain enzymes of their own that work with digestive enzymes to break down foods faster and allow your body to access nutrients quickly for cell reparation and growth.[iv]
Luckily, enzyme production is versatile and can be tailored to the composition of food consumed. However, if a diet doesn’t include this pairing of essential enzymes, or if the body is unable to produce enough enzymes to promote healthy digestion and diverse microbial life[v], you run the risk of malnutrition. This could lead to symptoms such as:
Lackluster hair, skin, and nails
To this end, maintaining a healthy diet is imperative to support the intricate process of enzyme production.
Immune System Support
Studies have shown that the immune system, which protects us from pathogens and harmful components in the environment, may owe its efficiency to digestive enzymes.[vii] As humans have evolved, enzyme production followed suit with microbial gut flora producing various enzymes to respond to different pathological and environmental threats. This line of defense allows the body to recognize and eliminate many dangers before they can infect the rest of the body.
In a study performed on rats, it was reported that aging affects the ability of the pancreas to produce enzymes. The rats were fed altered diets and the results showed higher adaptability in enzyme excretion in the younger rats than in the older ones. [viii]
As we age, our ability to adapt to changes in diet and nutrient absorption slows. In some, this can lead to chronic digestive ailments and, ultimately, other autoimmune dysfunctions if these issues are ignored. Though enzymes are not solely responsible for the aging process, they play a large role in how nutrients reach the areas that need them in all stages of life.
Enzymes and Chronic Stress
Our enzymes could be telling us to slow down. Chronic stress plagues countless individuals, but just because we always seem to be on the go doesn’t mean our food needs to be. It limits the number of enzymes your body can produce as the brain attempts to eliminate the stressor before it can re-engage in normal functions, like digestion. [ix]
This is a helpful reminder to slow down.
When we can’t digest our food, we can’t provide our bodies with nutrients. Recurring bouts of anxiety can lead to indigestion and even pesky habits like comfort eating and snacking.[x] As obesity levels skyrocket, it is easy to see how a simple change like sitting down for meals could provide a fulfilling way to destress and allow our enzymes to provide break down those nutrients that will speed us on our way.
Enzyme production is intrinsically tied to well-being and it is important to take them into consideration when planning for your health. Certain foods like pineapple, mango, papaya, and honey have been used in Central and South America for centuries to regulate digestion and inflammation in the GI tract.[xi]
If you ever become concerned about your enzyme production, supplements are widely available, though cheaper doesn’t always mean better. Make sure to check for quality ingredients that leave out fillers that could denature the enzymes. Talk to your doctor for more information and remember to take care of your enzymes so that they can take care of you.
