How Long Does Oatmeal Take to Digest?

By: Bob's Red Mill | April 4 2022

Have you ever wondered how long it takes to digest the meals you eat? If you have, you're not alone. The internet is full of questions and answers discussing the digestion process. The truth is, some foods digest quicker than others, and while you may not be able to time it, you can get a general idea of how quickly food moves through your system by observing how full you remain after eating.

Each body is unique, and each of us digests different macronutrients at different rates. One of the essential macronutrients that our bodies digest is carbs. Carbohydrates are the body's primary fuel source, and to keep our energy levels high, they need to be readily available to fuel the body at any given time.

Compared to other nutrients, carbohydrates have the shortest digestion time—especially refined carbs. Refined carbohydrates like cookies and crackers are digested quicker than unprocessed carbs. But, even though the energy they provide is quickly obtained, it's short-lived.

When searching for food that will keep you fuller for longer, reach for complex carbohydrates rather than refined ones. Complex carbohydrates are digested much more slowly. This slow digestion process allows them to provide a long-lasting, stable energy source. So not only will you remain satisfied for longer, but eating more foods rich in complex carbohydrates can help prevent unwanted energy crashes. In addition, the fuller you remain, the fewer  urges you may have to reach for unhealthy snacks.

Is Oatmeal a Complex Carbohydrate?

Oatmeal is often praised for being one of the healthiest energy sources around, but what makes it so? Not only does oatmeal provide complex carbohydrates to keep your body and brain fueled throughout the day, but it's also full of other nutrients. When you eat a bowl of oatmeal, the complex carbs deliver energy to your body. And because these carbs are slowly digested, the energy will last much longer.

In addition to being a complex carbohydrate, oatmeal is also a whole grain and much more nutritious than refined carbs. Whole grains contain all parts of the grain—the bran, germ and endosperm. This being so, they also have more nutrients and benefit your body in more ways than one.

Simple vs. Complex Carbohydrates

Are complex carbohydrates really that much better for you? Let's take a closer look at simple vs. complex carbs and the differences.

Simple Carbohydrates

Simple carbohydrates are those which are more easily digested by the body. Simple carbs can be found in healthy, whole foods like fruits and dairy. However, they are also found in processed, refined foods like pasta, sugar and bread. Eating simple carbohydrates provides you with a quick boost of energy, yet, once you've burned through that energy, you are met with an equally dramatic energy crash. To compensate for the energy you just used, your body overcompensates with rest causing you to feel lethargic and making it hard to stay awake.

Complex Carbohydrates

In comparison, because complex carbohydrates take longer to break down, the stream of energy is released over a more extended time. Complex carbohydrates are found in foods like vegetables, oats, whole grains and legumes. Because the build of energy is more natural when consuming complex carbohydrates, the fall of energy is equally as steady, and you don't experience a crash.

How Long Does Oatmeal Take to Digest?

So, how long does oatmeal take to digest? Since oatmeal is a complex carb, it's digested slower than foods containing simple carbs. However, oatmeal also contains dietary fiber, which helps with digestion and absorption. When these two factors are combined, the digestion time of oatmeal is relatively fast and takes about two to three hours. 

The Benefits of Consuming Oatmeal Regularly

Consuming complex carbs regularly can provide you with sustained energy levels and help you remain satiated throughout the day. A good source of complex carbs, starting your morning off with a bowl of oats is an excellent way to ensure that you remain energized and alert for the events ahead.

Oats Are Naturally Gluten Free

One of the things we love most about oats is that they're an allergy-friendly food. However, while oats are naturally gluten free, you'll want to check with the manufacturer to make sure they are processed in a gluten free facility.

And, despite their gluten free nature, cross-contamination is a concern when processed using the same equipment as other grains.

      Our oats do not contain milk. There is a small percentage of the population that cannot tolerate oats, unfortunately. We recommend bringing this up with your doctor or health professional.
