Is Oat Bran A Nutritious And A Low Carb Oatmeal?

Is Oat Bran A Nutritious And A Low Carb Oatmeal?

Low carb oatmeal may sound like an impossibility, but if you plan carefully, it can even help reduce your glucose spikes.

Oat bran is fibrous, but don’t let that scare you away; it can taste great and be healthy on almost any meal plan!  Is oatmeal keto friendly?  It sure can be if you eat it in the ways suggested in this post.

Oat bran nutrition is off the charts compared to other grains and it won’t spike your blood sugar like many grain options.  I personally love cream of oats variety of oat bran, which is a tasty sub for the less-nutritious cream of wheat.

It is easy to make low carb oatmeal recipes with oat bran too. Learn why you can include oat bran even if you are limiting carbohydrates. First, find out what oats really are and how they found their way into our homo sapiens diet.

History of Oats

Oats (Avina sativa) are a type of grass seed that are thought to originally be from West Asia and first eaten around 2000 B.C.  Oats were probably only eaten as weed seeds that far back as part of a foraging diet.

Oats took a long time to get popular because people generally weren’t as first fond of the taste. This is probably because they are higher fat content than other grains, and are more susceptible to spoiling.

People in northern Europe, such as Scandinavia and Scotland, grew more oats than other countries because it is a crop that does better in colder weather.

Oats gradually gained more popularity across the world.  Most oats on the market today are heated to reduce spoiling, so tastes are much improved!

 

What is Oat Bran?

Oat bran is the fibrous, protective coating of the oat seed that is packed with nutrition.  The fiber of oat bran is softer than that of wheat or other grains because its fiber content is more soluble. Because of the high fiber content of oat bran, it can be a low carb oatmeal when it is prepared properly.

This is not the same as whole oatmeal, which is NOT considered low net carb.

Soluble fibers soak up water more easily than non-soluble fibers. Therefore, oat bran has a smoother, more palatable texture than wheat bran.

Oat Bran Nutrition

Most grains are rich in one or more nutrient, but oat bran stands out for nutritional content over other grains.

Oat bran is a very rich source of magnesium.   This is important because magnesium is a critical nutrient that so many people lack. It is also a good source of other minerals, including phosphorus and selenium.  Oats are one of the highest food sources of thiamine (vitamin B1).

Oat bran fiber is very unique in structure.

Oat bran is very slowly digestible and even reduces glucose levels. The same can’t be said for other grains like wheat or rice.

Oats are the also the only food to contain a powerful antioxidant called avenanthramide, which gives oats unique health benefits.

Oat bran nutrition contents per 1 oz and percent daily value of the Recommended Daily Intake:

Calories 69 na
Carbohydrate 18.5 g
Fiber 4.3 g 17%
Net Carb 14.1

What is a Net Carb?

Is oat bran oatmeal a carb?  We must consider net carbs in all foods to understand what the effect on your body will be in terms of glucose.

No single food is purely carbohydrate, unless it is highly processed.  Oatmeal that is made with oat bran is a balance of healthy fats, fiber, protein, and slowly digestible carbohydrate.

Net carbs in oatmeal are easy to calculate. Net carbs are more important than total carbs in terms of determining if oatmeal is keto friendly.

When we consider whether foods have carbs, it is important to realize that not all carbohydrates absorb and turn into sugar in the body.  Fiber does not absorb, yet fiber carb amount is part of the nutrition facts on food labels.

Oats have carb or carbohydrates; that’s a fact.  However, they are lower in net carb and further, slowly digestible carbs.

How do I find out net carbs in oat bran?

Net carbs in oatmeal is a calculation you can do:  simply subtract the fiber from the carbohydrate count.

The net carb is a slowly digested or non-digested form of carb. Total carbs are misleading on labels in this way.

To find out net carbs in oatmeal bran, simply take the total carb of 18.4 g and subtract the fiber content of 4.3 and you get net carb amount of 18.1 grams.

 

Is Oatmeal Keto Friendly?

Ketogenic diets are being used for many health conditions.  Always check with your healthcare provider before embarking on a keto meal plan. Having said that, ketogenic diets are showing possible benefit in numerous health conditions, including weight management, diabetes, cancer, brain injuries, seizure disorders, skin conditions, and more [R].

This is not an endorsement for a low carb diet, but it is an informational post providing you with information you can use if deemed medically appropriate for you.

Oat bran, when prepared correctly and eaten at correct times,  can support a keto diet in the following ways:

  • Low glycemic index
  • Reduces insulin spikes
  • May reduce cholesterol
  • Helps support healthy weight

If  used as suggested in the post, you can have oatmeal keto friendly recipes.

Oat Bran Glycemic index

Glycemic index is another factor to consider when determining if oatmeal affects your glucose and overall response to carbohydrate.

Oat bran has a glycemic index of 50, making it a low glycemic index food. This means it does not spike blood sugar quickly after a meal. This further answers the question about oatmeal carbohydrate amounts that matter.

Translation: oat bran is a low net carb and low glycemic index food, making it suitable for most people, even on low carb diets.

 

Is Oat Bran Gluten Free?

For many people on low carb diets, it is important to consider the gluten content. Are oats gluten free? Gluten free oats with less than 20 parts per billion of gluten can technically be considered gluten free and do not seem to cause symptoms in most patients with celiac disease.

When choosing oats and oat bran, make sure to find labels that say gluten free, as some oats can be contaminated with other grains with gluten.

If you have celiac disease, a small percentage of you may still have sensitivity to gluten-free oats.  Why?  According to the Celiac Disease Foundation, oat contain avenin, a protein that is similar to gluten in structure that activates immune cells.

Generally, people with non-celiac gluten sensitivity can tolerate gluten-free oats.

Beta Glucan in Oat Bran

Oats stand out over some grains because they contain a fiber type called beta glucan.

Beta glucan is a viscous or soluble type of fiber found in things like oats, yeast, bacteria, mushrooms, and algae.

Oat bran is the most concentrated place of beta glucan in oats. It is a type of fiber that has a lot of research supporting health benefits, including digestive benefits, and it may reduce certain types of cancer.

The beta glucan content of oat bran is between 15-40% of the total weight, making it very concentrated of this healthy fiber.

Oatmeal Lectins

When you eat any grain, an important factor that may affect your health is called lectins. Lectins are a type of protein that can have both positive and negative effects on the body.

Lectin sensitivities, including oatmeal lectins, are thought to contribute to gastrointestinal inflammation and leaky gut.

Do oats have lectin?  Probably, although no research is available regarding this topic.  Some ways to reduce lectins in any foods, including oats include:

  • soaking
  • sprouting
  • cooking

Low lectin diets became popular with Dr. Gundry’s Plant Paradox protocol a few years ago.  While research is early in regards to lectins and health, many people do feel better if they limit lectins, especially if they have autoimmune issues.

Lectin foods also tend to be foods that are high in FODMAPS, so a low lectin diet dovetails nicely with a low FODMAP diet.

Oat Bran Health Benefits

The list of oat bran health benefits are long.  While we know lots of facts about oat bran and health, I always recommend listening to your body when eating them first and foremost.

If oat bran makes you feel good, enjoy them as part of  low carb oatmeal recipes.  If they throw off your digestion, you should probably skip oat bran.

Can Be a Healthy, Low Carb Oatmeal

Eating oat bran on a low carb diet can fit in well, even if following a keto diet.  How is this possible?

While oat bran is not technically low carb on its own, it can be if prepared correctly. See below for some recipe options.

You will soon find out that oat bran acts low carb in the body as well; it reduces blood sugar spikes and insulin levels!

While some experts extol the keto diet and others scoff at it, keto has its health benefits and can be useful for some health conditions. Always seek advice from a health professional first.

Based on research, oat bran can be a great add in as a keto low carb oatmeal because of its metabolic benefits.

Additionally, many athletes who follow a keto diet include carbohydrate sources before exercise and still remain in ketosis as well. These keto diets include:

  • the targeted keto diet
  • cyclical ketogenic diet

Personally, keto isn’t for me because I’m already very lean with a high metabolism, but I am mindful of having healthy carbs and including  low net carbs.

Oat Bran Heart Benefits

We must always consider heart health when we talk about foods because heart disease remains the number one cause of death in the United States.

A compilation study of 14 clinical trials concluded that oat bran reduces total cholesterol, LDL cholesterol, after-meal glucose spikes, hemoglobin A1C, and insulin levels.

Another similar study of 28 clinical trials concluded that adding 3 grams or more of oat beta glucan per day robustly reduces LDL cholesterol.

Oat bran reduces harmful cholesterol by complex mechanisms in the food structure. It may also help increase fat breakdown, or lipolysis, as well.

Oat bran may also have heart health benefits because it may:

  • Reduce immune cell (monocyte) stickiness in the artery walls
  • May reduce release of proinflammatory compounds in immune cells
  • Reduces LDL cholesterol can improve on average 23 percent

Oat Bran Digestive Health Benefits

Oat bran has many potential digestive health benefits.  This includes:

Feeds the gut: Fibers in oat bran help provide fuel for digestive cells.  They increase a type of nutrient in the gut calledshort chan fatty acids .  is a type of fat that is known to help improve digestive health. Oat bran may increase the body’s butyrate level s in the digestive tract.

Reduces constipation: Adding fiber-rich foods to the diet like oat bran can reduce constipation as well as laxatives, according to recent research.  The majority of people find constipation relief when adding more fiber to their diet. Fiber-rich foods can also reduce diarrhea symptoms in some people! Be careful to also increase fluids in your diet when you increase fiber.  Make sure to also increase fiber in your diet gradually to avoid side effects.

Has prebiotics: Oat bran, a type of prebiotic, may improve the growth of beneficial bacteria in the digestive tract as well.

Make sure to also stay active and eat a well-balanced diet to have the best digestive health.

Oat Bran Improves Diabetes

14 studies have shown that oat bran is useful to manage diabetes. That’s pretty strong evidence.

Oat bran reduces the body’s insulin response to meals and also suppressed gene sets related to insulin levels in a small clinical study. This is a good thing because insulin spikes are linked to heart disease and diabetes complications, along with cancer risks.

Eating oat bran before a meal may also reduces the glucose spike from foods, thereby fitting into a low carb oatmeal recipe.

In summary, oat bran may:

  • Reduce glucose spikes
  • Reduce insulin spikes

Cancer Risk Reduction

Foods high in soluble fiber, such as oat bran, may reduce chances of estrogen receptor negative breast cancer.

Oat bran contains an anti-inflammatory compounds called avenanthramides, which may reduce growth of colon cancer cells as shown in cell studies.

Foods like oat bran that increase butyrate levels in the digestive tract may reduce colon cancer risk.

While research remains preliminary in this area, oats may have a protective effect against cancer.

May Support Weight Loss

Although no single food or ingredient can work alone for weight loss, nutrient-dense foods with low glycemic index often support weight loss.  Oat bran is no exception.

A long term study showed that people with diabetes eating 100 grams of oat bran per day for a year had more weight loss than those who didn’t.

Long term studies like these suggest that oat bran as part of a long term plan may be more beneficial than harmful for weight loss.

Oat Bran for Immune Benefits

Most of the research so far on oats and immunity has been in animal studies, but oat beta glucan looks promising for healthy immunity.

Oat bran is 15-40% beta glucan content.  Beta glucan may help immune function by [R] [R]:

  • Improving resistance to viruses
  • Reducing inflammation markers
  • This includes reduced gene levels of in the colon and cecum:
    • IL-8
    • NF-κB
    • TNF-α
  • Increasing beneficial bacteria amounts in the colon.
  • Improving innate immune response to infection

 

May Improve Exercise Endurance

For best health, it is important to exercise and feel good when exercising.  Early research suggests that oat bran may improve exercise.

An example of this: oat bran given pre-exercise reduced time to exhaustion and reduced inflammation in a study of mice.

Research in this area remains preliminary.

Best Oats for Health

It is best to choose oats bran over oatmeal if you are looking for a low carb oatmeal. Make sure to choose oats that have no added sugar or added salts. Some convenience oatmeal or instant oatmeal brands add a whopping 12 grams of sugar per tiny serving!

Choose the following healthy oat options:

*Oat groats are simply the whole oat seed with the hull removed.

Wheat Bran Versus Oat Bran

Why should you choose oat bran over wheat bran? Nutritionally, wheat bran and oat bran are quite different.

Oat bran has more of the following nutrients than wheat bran:

  • protein
  • soluble fiber
  • fat
  • thiamine
  • folate

Wheat bran has more insoluble fiber, niacin, and vitamin B6 than oats. Both are quite high in magnesium.  For those with gluten sensitivity, oat bran is a much better choice.

Oat bran is more likely able to increase the growth of beneficial bacteria, or probiotics, in the digestive tract because it is more easily fermented.

The texture of oat bran is much more creamy when cooked as a cereal than wheat bran. This makes it a very good add-in for recipes and a great substitute for more processed grains.

Oat Bran Forms

Many companies sell oat bran, including gluten-free oat brans.

Oat bran can be coarsely ground or finely ground, as is the case for cream of oats.

Cream of oats is a relatively new product from a company called Montana Gluten Free.  It is a finely ground oat bran.  I  fell in love with it because it is so tasty like Cream of Wheat. It also has 9 grams of protein per serving; unheard of for hot cereal recipes! It can be a great meal for keto diets on exercise days too.

I no longer can eat Cream of Wheat because I’m sensitive to gluten, so I was delighted to find this comfort food.   Cream of oats is same in taste and texture as cream of wheat, but so much more nutritious!

Buy Oat Bran

It can be confusing when shopping for healthy oat bran to include in your low carb oatmeal recipes.  I will show you some of my favorites so that your shopping is simplified.

Healthy Low Carb Oatmeal Brands

Gluten-free oat and oat bran options that go great in your low carb oatmeal recipes are challenging to find. Most aren’t organic or gluten free, so be careful when shopping.

My criteria:

Organic

Certified Organic oat brans are ones that have been inspected and meet the strict criteria for organic. They do NOT spray their crops with Round Up (glyphosate). This herbicide now implicated in cancer risk.

Gluten free

You can find gluten free, organic oat bran at many online retailers like Amazon and in most grocery stores today. You must make sure the label states that they are gluten free with the certified gluten free label.

I  like the following gluten free, organic keto friendly oatmeal products:

  • Food to Live organic oat bran, raw and gluten free, 3 lbs for $17.99
  • Mulberry Lane Farm certified organic oat bran, 5 lbs for $27.99.
  • Montana Gluten Free cream of oats, certified organic, 3 lbs for $27.95.  I would rate the taste and texture much better than the reviewers on Amazon.  I think the reviewers were confused and thinking they bought cream of wheat.

Oat Bran Recipes

You can easily sub out oat bran or cream of oats into ANY of your baking recipes to improve health. Add in oat bran anywhere recipes call for flour ingredients. These can be part of many low carb keto recipes too.  They can add some variety and flavor into recipes that call for almond flour as well.

Ideas:

  • Add to your smoothies for a nutrient boost
  • Mix into plain yogurt for breakfast
  • Sub out unhealthy white flour with oat bran
  • Use instead of wheat bran for a gluten-free option
  • Make a quick power breakfast using the following recipe!
  • Oat bran flour can be a nice baking flour because it draws moisture to it
  • Use half almond flour and half oat bran flour for improved recipe texture

Low Carb Oatmeal Recipe

Keep in mind, this recipe can be one of your low carb recipes because it is low NET carb.  Because of the low glycemic index and high protein content, it will be slow to digest, making it ideal for keto oatmeal recipes and keto breakfasts.

Here are some easy substitutes and add-ins:

  • If you want extra protein, simply add a scoop of your favorite protein powder.
  • Leave out the raspberries if you want it to be sugar free.

    1. The texture and nutrition will be different and the cooking time will be different. I suggest using cream of oats for this recipe. Thanks for reading my post!

  1. […] I searched high and low for research related to the content of lectins in oatmeal.  I turned up empty-handed.  Some types of oats contain gluten, so if you are gluten-sensitive or have autoimmune issues, it may be best to avoid.  Read more about oatmeal and low carb oatmeal recipes here.
