Whether you are trying to reach new fitness goals or simply want to have a healthier lifestyle, the first place to start is with food. While this seems simple enough, trying to figure out what to eat and not eat for your fitness goals can be stressful, especially when it comes to breakfast.
Two of the main contenders for a healthy start to your day are Oatmeal and Cheerios. Both Oatmeal and Cheerios are backed by the American Heart Association because of their heart-healthy low cholesterol amounts.
But what if you do not have to worry about cholesterol? Which breakfast cereal is right for you? This article will examine Oatmeal and Cheerios side-by-side so you can decide which one is right for you.
Oatmeal vs Cheerios Nutritional Comparison
While there are a variety of flavors for both Oatmeal and Cheerios, for the sake of this article I will be comparing Plain Old Fashioned Rolled Oats versus Original Cheerios.
Right away, the two have one ingredient in common – oats. This makes either Oatmeal or Cheerios a great option if you are on a gluten-free diet.
But let’s continue comparing the nutritional content of Oatmeal and Original Cheerios. We will examine everything from calories to taste. Each category will be based on the serving size of each cereal.
Best for Calorie Content
We begin our comparison with calorie content. The serving size for each cereal varies slightly. The serving size of Old Fashioned Rolled Oats is 40g. The serving size for Original Cheerios is 39g.
Per serving, the calorie content of Oatmeal is much higher than Cheerios. However, if you increase your serving size of Cheerios to 100g, Cheerios is much higher in calories. The winner in this category will depend upon your serving size.

Best for Carbs & Sugar Content
Carbohydrates and sugar content are the two tougher categories and need to be carefully considered side-by-side if you need to monitor your sugar intake.
Oats are naturally high in carbs and it is the main ingredient in both Oatmeal and Cheerios. Because Cheerios has additional ingredients in it than Oatmeal does, Cheerios has the higher carb amount in this category.

When it comes to the amount of sugar in Oatmeal versus Cheerios, this is where we have to look much closer. Oatmeal only has one ingredient – oats. The added ingredient of sugar in Cheerios makes it considerably higher in sugar content than Oatmeal.

Best for Fat Content
Oatmeal and Cheerios are both naturally low-fat foods. They both also offer the same amount of heart-healthy polyunsaturated and monounsaturated fats, per serving, which is so good for your heart.
There is not a big difference in fat content between Oatmeal and Cheerios but if you are trying to stick to a low-fat diet, Oatmeal is the right choice for you.

Best for Fiber Content
Oats are naturally high in fiber. Because of this, both Oatmeal and Original Cheerios are comparable when it comes to fiber content. There is no difference in fiber content, regardless of the serving size.
The only difference between the two is that Oatmeal provides both soluble and insoluble fiber while Cheerios only offers soluble fiber. This is important to know because these two types of fiber are very different.
Soluble fiber improves digestion, promoting bowel movements. Insoluble fiber softens the stool.
Again, depending on what your specific health needs are, these two types of fiber can also help in the decision-making process.

Best for Sodium/Salt Content
With both Oatmeal and Cheerios being backed by the American Heart Association as being part of a heart-healthy diet, you would naturally assume that they are both low in sodium. This is where there is a stark contrast between these two.
There is no sodium/salt in Oatmeal. Cheerios, however, are considerably higher in sodium/salt content.

Best for Vitamins/Minerals
Oats are powerhouses when it comes to fiber but not so much when it comes to vitamins and minerals. Because of this, most cereals, such as Cheerios, are fortified with additional vitamins and minerals.
As you can see from the chart below, the addition of vitamins and minerals gives Cheerios the upper hand in this category.
Oatmeal and Cheerios contain the same amount of potassium but Cheerios is far superior in the other vitamins and minerals, especially potassium.
