If you are an oat lover, you have probably noticed there are many different oat products available. You may have seen oat bran vs rolled oats. You may be wondering what’s the difference, and how are you supposed to use them all?
This article goes over the differences between oat bran vs rolled oats products and the best ways to use each of them.
The four oat products that are compared in this post are oat fiber, oat flour, oat bran, and oatmeal.
Oat bran is the outer layer of the whole oat and is high in protein and fiber. It can be used on its own to make a hot porridge, or as a topping for yogurt and smoothies.
Finally, rolled oats are made from whole oats. There are multiple types of oats, which will be looked at in greater detail later in the article. These are the oats used for regular oatmeal. You are probably most familiar with these types of oats as they are used for regular oatmeal and are often used on their own to make breakfast cereals like hot porridge, hot cereal, overnight oats, or in baking.
Why Are Oat Products So Popular?
Oat products are very versatile and can be easily incorporated into anyone’s daily eating habits.
They are nutrient dense, offering dietary fiber, protein, and vitamins and minerals such as B vitamins, zinc, iron, calcium, and potassium.
They are also gluten free and keto friendly!
Health Benefits of Oat Bran vs Rolled Oats
Oats and oat products are a superfood. They offer a variety of health benefits including digestion, heart health, blood sugar regulation, weight management, and cancer prevention!
Oat products are high in fiber, which helps promote healthy digestion and bowel movements, preventing constipation.
Oat products include both soluble and insoluble fiber (except for oat fiber which is only insoluble fiber).
Soluble fiber content (also known as beta glucan) helps to absorb water in the digestive tract and slow the digestion process, which helps with nutrient absorption (1). Insoluble fiber is needed to build bulk for our stool (1).
Soluble fiber will bind cholesterol, causing it to be excreted in our stool rather than absorbed into the bloodstream (1).
This is important because a buildup of LDL cholesterol in the bloodstream can cause blockages in the arteries, which puts strain on the heart, putting you at a higher risk for heart disease.
Fiber also helps to control blood sugar levels (2).
Blood sugar refers to the amount of glucose that is found in your blood. When we eat carbohydrates, our bodies break them down into glucose, which is then used for energy.
However, having too much glucose in your blood can be harmful and is a condition called hyperglycemia (or high blood sugar), often seen in those living with diabetes.
Fiber is a type of carbohydrate that passes through our digestive tract without being broken down into glucose. Because of this, it does not raise blood sugar levels.
As mentioned before, fiber also helps to slow down digestion of sugar which can prevent spikes in blood sugar after eating.
Since fiber helps to slow down digestion, it helps to keep you feeling full for longer after eating, meaning you will be less likely to overeat.
When combined with other healthy choices, such as exercising, eating more fiber can help maintain a healthy weight.
It has been suggested that a diet with high fiber intake can help to lower the risk of breast cancer as well as colorectal cancer (2).
What Is Oat Bran?
Oat bran is the outer part of the whole oat (with the husk removed) which is removed from the rest of the oat and used on its own.
The oat bran is where most of the nutrients in whole oats are found. It contains more protein and fiber when compared to oatmeal.
Oat bran is high in soluble fiber, which absorbs water in the digestive tract, helping with bowel function.
Soluble fiber may also help reduce risk for heart disease and lower LDL cholesterol, blood pressure, and blood sugar levels (3).

Taste and Texture
Oat bran has a smoother and creamier texture compared to oatmeal; however, the taste is very similar.
Uses In Cooking And Baking
Oat bran can be added into baked goods such as muffins and cakes. Or, it can be used on its own to make a hot porridge or overnight oat bran, similar to how we often use oatmeal.
It can also be used as a topping on yogurt, cereal, or smoothies.

Can It Be Made At Home?
Oat bran can be made at home using a food processor or blender.
First, take whole oats and pulse them into a course powder. Then, sift the powder to separate the bran, which can then be used on its own (6).
- Wheat bran
- Rice bran
- Corn bran
What Is Oatmeal?
Oatmeal is made from different forms of oats, all of which consist of the whole oat grain. They all have the husk removed but are then processed differently.
Oat groats are the least processed form, with only the husk removed and no further processing done.
There are also steel cut oats, rolled/old fashioned oats, quick oats, and instant oats.
Steel cut oats are made by using steel blades to cut oat groats into 2 or 3 pieces.
Rolled/old fashioned oats are made by first steaming the oat groats, then rolling them out, resulting in a flattened oat.
Quick oats are made the same way as rolled oats; however, they are rolled even thinner in order to shorten the cooking time.
Finally, instant oats are also made by first steaming and rolling the oats but are then pre-cooked and dried again so that the cooking time will be even shorter than for quick oats. One thing to watch for in instant oats is added sugars. Choose one with the only ingredient as oats, if possible.
Since oats consist of the whole grain, they have both soluble and insoluble fiber. As mentioned earlier, fiber helps with digestion as well as lowering the risk for heart disease.
In a serving size of 1 cup (234g) of plain cooked instant oats (made with water) (7):
