During my health coaching sessions many people ask me about oatmeal and its variations. I’ll take a close look at both in the following sections.

Oatmeal: A Basic Overview 

Oatmeal is the whole oat grain or the “groat.” The groat can then be processed in a few different ways1.

The two most common processing options result in either steel-cut oats or rolled oats. Steel-cut oats are processed by being cut into small pieces with a steel blade and rolled oats are rolled flat.

Pros of Oatmeal

  • Chewier texture
  • More affordable
  • Versatile

Oatmeal has a chewier texture, therefore it may be preferable for those who do not enjoy the creaminess of oat bran. In addition, it’s cheaper than oat bran. Those of you on a strict budget will enjoy many of the health benefits of oats without breaking the bank if you choose oatmeal. 

Additionally, oatmeal is a versatile food, meaning you can eat it in many different ways. This is a pro for people who do not like to eat the same meal all the time.

Whole oats can be mixed into many different recipes to add variety to your mealtime routine2. 

Cons of Oatmeal

  • Higher in carbs
  • Can cause bloat or gas
  • Allergies
  • May worsen irritable bowel syndrome
  • Contain physic acid

Oatmeal is high in carbohydrates3. Due to this, it may not be a good option for those on low-carb or keto diets. Although oatmeal is considered a healthy carbohydrate. 

It can cause bloating or gas due to the amount of fiber in it. Some people are allergic to oats, and they can worsen the side effects of irritable bowel syndrome. 

One concern with eating any type of oats is the presence of phytic acid in the grain. Phytic acid has anti-nutrient properties, which means it can block your body from absorbing certain nutrients like zinc and calcium4.

You can mitigate this effect by adding lemon juice or apple cider vinegar to your oats, but it will affect the flavor.

Oat bran is just part of the grain, the outer layer5. Thus, oat bran is not a whole grain like oatmeal is. However, oat bran makes up for this fact with several health benefits compared to oatmeal. It can be eaten in many similar ways to whole oatmeal but has different health benefits.  

Pros of Oat Bran
