Starting your day off with a high-fiber meal is the best way to start your day. You will feel fuller for longer and you will be giving your body what it needs to stay healthy.

Two contenders for a high-fiber start to your day are bran and oats. Both offer a variety of health benefits in addition to fiber. So how do you know which one is right for you and your family?

In this article, I will be comparing Fiber One cereal and Oatmeal. By the end of the article, you will be able to make an informed decision that is right for you and your health needs.

Fiber One Cereal vs Oatmeal

Fiber One Cereal vs Oatmeal Nutritional Comparison

The only way to know whether Fiber One Cereal or Oatmeal is the healthiest choice for you is to compare the two side-by-side.

Fiber One cereal has a Honey Cluster option, but for the sake of this comparison, I will be comparing General Mills Fiber One Original Bran cereal versus Old Fashioned Rolled Oats.

The serving size for each cereal varies when measured in cups so to make this comparison fair and easier to understand, I will do the comparison by weight. Each serving of cereal will be compared in a 40-gram serving.

Best for Calorie Content

The first item listed on every nutrition label after the serving size is calories. This is really important if you are on a calorie-restricted diet or simply want to keep your caloric intake down.

Again, both items are compared in a 40-gram serving size. When you compare Original Fiber One cereal versus Old Fashioned Rolled Oats, Oatmeal has a higher calorie content than Fiber One.

Best for Carbs & Sugar Content

Bran and oats are naturally high in carbohydrates but Fiber One Original Bran cereal is considerably higher in carbs than oatmeal.

To be fair, Fiber One cereal has added ingredients so this will make the cereal higher in carbohydrates than oatmeal, which only contains oats.

Both Fiber One Original Bran cereal and Oatmeal contain no sugar but the reason why is what really sets these two apart.

Oatmeal only contains one ingredient – oats. Fiber One, on the other hand, contains the added ingredient of sucralose. Sucralose is a man-made zero-calorie sweetener.

Best for Fat Content

When it comes to comparing fat content, I will be comparing more than just total fat per serving. We also want to look at the different kinds of fat in Fiber One and Oatmeal.

Saturated and trans fats are what are typically called “the bad fats”. Polyunsaturated and monounsaturated fats are “the good fats”.

Oatmeal has a higher fat content than Fiber One but it is also higher in polyunsaturated and monounsaturated fats.

Best for Fiber Content

According to many nutritionists, dietary fiber is crucial to having a healthy body. A diet that is low in fiber puts you at risk for diabetes, heart disease, and even some types of cancer.

There are actually two types of fiber: soluble and insoluble. Soluble fiber becomes gel-like, making bowel movements easier to pass. Insoluble fiber promotes movement through the colon. Both types of fiber are crucial to a healthy colon, heart, and weight.

Fiber is one area where we would expect our two contenders to be the same but this is actually where they differ quite a bit.

Fiber One cereal contains wheat but also the added ingredient corn bran, making it much higher in fiber content than Oatmeal.

Best for Flavor/Texture

This category is, honestly, the most important. Regardless of how healthy a food is, if we do not like how it tastes, we will not eat it.

Fiber One is rough in texture until it is combined with milk but it is much sweeter than Oatmeal. Oatmeal, on its own, is softer in texture than Fiber One and it has a mild, naturally sweet flavor.

Flavor and texture are such personal preferences that you should be the judge of this category.
