Oats Side Effects (Is It Good To Eat Oatmeal Every Day?)

Quick Answer: What Do Oats Taste Like?

Contents show

Oats have a nutty, sweet flavor that is often described as bland, which is what makes them so perfect for breakfast. It is the lack of any distinctive flavor that makes oats so versatile. They can be used in savory dishes as a cereal or in sweet dishes as a sweetener.

Oats (Avena sativa) come from a grain in the Poaceae family. The grain is the seed from the oat plant. This classic breakfast staple has many health benefits. It’s a great source of fiber, thiamine, magnesium and zinc.

Oats are a great addition to a well-balanced diet. Promoting heart health, weight loss and digestive health if used properly, it’s a great food.

However, not all is always well with oats. This cereal grain does have some side effects. Some are simply uncomfortable, while others can be quite serious.

Below, we will explore these side effects. We will suggest alternatives and discuss other important issues about oats. 

Oats Side Effects


1. Bloating And Gas

 Bloating and gas are uncomfortable, painful, and can be embarrassing. Sometimes the fiber in oats can cause these digestive difficulties.

The fiber in oats cannot be digested when it gets to the body’s lower intestine. It gets broken down by naturally occurring bacteria in that area. As this happens, hydrogen and carbon dioxide form. Methane will also be produced.

These gasses will build up and can cause bloating and pain. When expelled, it will have a bad odor from the methane. 

2. Weight Gain

Eating a lot of oats or oatmeal may cause weight gain. But the problem is not the oats themselves. The issue comes from the extra mixtures and toppings people often add. Items like:

  • White sugar
  • Chocolate chips
  • Whipped cream
  • Nutella
  • Dried fruit (has a lot of sugar)
  • Brown sugar
  • Carb heavy fresh fruit (like bananas)

We think we’re being healthy by choosing oatmeal. But, attention needs to be paid to what we add. Oatmeal does have a significant amount of carbs.

So, for example, if a banana, brown sugar, and some chocolate chips are added, you’ve now made your healthy breakfast into a carb-loaded, sugary caloric disaster.

All of these yummy toppings add up calorie wise. If eaten every day, it will add up on the scale as well.

Jazzing up oatmeal can be tasty and healthy by choosing healthy alternatives like:


– Cinnamon, nutmeg

Fresh Fruit

– Some low carb choices include coconut, blackberries, raspberries, strawberries, and pears.



3. Decrease In Nutrition/Malnutrition 

In some cases, too much oatmeal can lead to the body not getting all the nutrients it needs. In severe cases, this will lead to malnutrition.

Malnutrition can occur not only when people don’t eat, but when they don’t eat enough of the right foods. Oatmeal is quite filling.

It’s easy to forget your next meal after having had a bowl. If the belly is full, it won’t signal your brain that it’s time for the next meal.

In addition, oatmeal does not have all of the nutrients the body needs. So, if you only eat oatmeal every day, you deprive your body of other needed vitamins, minerals, and proteins.

Over time, this practice can cause the body to lose muscle mass, affect cognitive abilities, and organ function.

4. Allergies

Allergies are one of the major side effects of oats. Often, people are allergic to the protein avenin that’s contained in wheat. While others may have a reaction to the gluten protein that’s in wheat.

Although oats do not contain gluten, they are usually grown and processed in areas that handle wheat. If a gluten allergy is present, it’s important to check labels. Make sure that all oat products purchased are labeled as gluten free.

Symptoms of an oat allergy include:

  • Blotchy/itchy skin
  • Rash
  • Scratchy throat
  • Runny or clogged nose
  • Itchy eyes
  • Nausea
  • Diarrhea
  • Stomach pain
  • Difficulty breathing

Things to avoid if you have an oat allergy include:

  • Oatmeal baths
  • Oatmeal lotion
  • Granola
  • Beer
  • Oat milk
  • Horse feed (such as hay)

What Can Be Substituted For Oats?


Whether you are allergic, intolerant , or just plain, don’t care for oats. There are plenty of delicious, healthy alternatives out there. 

Brown Rice

  • This rice is full of fiber, protein, magnesium, and selenium. For a great breakfast bowl, take some cooked brown rice and combine it with some milk, honey, fruit, and cinnamon.


  • Quinoa is high in protein, iron, and folate. A quinoa breakfast bowl can include some cooked  quinoa ( simmer it in almond milk for a great flavor), drizzle with some honey, and add some fruit or nuts.


  • This high protein, earthy grain is great for breakfast. Combine the buckwheat, milk of your choice, and some fruit.

Chia Seeds

  • These tasty seeds are good if you’re on a low carb diet. Top them off with some shredded coconut.


  • Naturally gluten free and filled with vitamins, millet tastes great too. You can quickly simmer it with some milk. Then add nuts or any other healthy topping


  • This ancient grain is delightfully sweet and rich in iron. It can be whipped up in a sauce pan with  some milk. 


  • Full of B vitamins, flaxseed makes a great porridge. Combine the grain, coconut milk, vanilla, and cinnamon for a tasty treat.

Wheat Berries 

  • Wheat berry is not a berry, but a whole grain. They have some crunch to them, like granola. Full of fiber and protein, they make a great substitute for oats.

Nuts And Seeds

  • Great if you’re on the go. Just make a snack bag out of these yummy, natural foods. You’ll get many of the same benefits as oatmeal.

What Are The Different Types Of Oats?

There are several different types of oats. Decide what’s best for you based on time and dietary needs.

1. Whole Oat Groats

Oat groats are when the oat grain is in its most organic or intact form. The hull was removed but the bran, germ, and endosperm are still there. This oat takes the longest to cook, at about 40 to 45 minutes. The texture is that of barley or rice

2. Steel Cut Oats

Also known as Irish Oats. As the name suggests, these oats are produced by cutting the oat groats with a steel blade. This gives them a chewier consistency than the whole oats. Steel cut oats take about 20 to 30 minutes to cook. 

3. Scottish Oats

These delightful oats are made by stone grinding the oat groats. This makes them great for porridge. Cook in about 10 minutes.

4. Rolled Oats

One of the most popular oat forms. They’re made by steaming the oat groats. Then, roll them flat with steel rollers. It takes about 5-10 minutes to cook.

5. Quick Oats

These oats are similar to rolled oats, but they are steamed and rolled thinner. Sometimes they are chopped into smaller pieces.  So they have a quicker cooking time of 1-3 minutes.

6. Instant Oats

These are the most processed of all the oats. After rolling and steaming, they are pre-cooked, chopped, and dried. These oats cook the fastest , needing only a quick blanching or zap in the microwave. 

7. Oat Bran

Oat bran is a by-product of oat manufacturing. It’s actually the outer layer of the oat groat. 

8. Oat Flour

Oat flour is simply finely ground oats. It’s often used in baking products and as a thickening agent.

What Are The Nutritional Facts Of Oats?

One-half cup of dry, uncooked oats has the following nutritional value:

  • Calories: 153
  • Protein: 5 grams
  • Fat: 3 grams
  • Carbohydrates: 27 grams

  • Copper: 17% daily value
  • Iron: 9% daily value
  • Folate: 3.2% daily value
  • Vitamin B1: 15% daily value

2. Rich In Antioxidants 

Antioxidants can help lower blood pressure, widen blood vessels, help prevent cancer, and have an anti-inflammatory effect. 

3. Contain Soluble Fiber

Fiber helps reduce overall cholesterol levels. It also reduces blood sugar and increases fullness

4. Helps Prevent Heart Disease

If cholesterol is reduced, so is the progression of heart disease.

5. Oats Help In Controlling Blood Sugar

These grains can help lower blood sugar. This is especially useful for people with diabetes or weight issues.

6. Weight Loss

8. May Relieve Constipation

Studies have shown that regular consumption of oat bran can keep your digestive system in check. 

How Should Oats Be Stored?

Oats should be kept in a cool, dry place. Typically, they will stay fresh for 18-24 months. Once opened, put the oats in an air-tight container or in the freezer.

Oats will still be safe to eat after the expiration date. The date is just a fresh suggestion. But make sure they don’t smell or have bugs.

What Are Some Mistakes People Make With Oats?

If you don’t perform certain tasks correctly when it comes to oatmeal preparation, they may not be enjoyable or even edible. Some mistakes people make are:

Making It With Water Instead Of Milk.

  • We may think it’s healthier, but usually we just succeed in making it bland and soupy. You want a creamy consistency for your oats. If you don’t want cow’s milk, almond milk is a nice alternative. 

Using A Small Pot Or Bowl

  • Remember that oats tend to expand. So what fits in before cooking may spill over and cause a mess later.

Adding The Oats At The Wrong Time

  • Waiting until the water simmers is your best bet. Adding the oats too early can cause them to be sticky or even soggy.

Not Adding Salt

  • Adding just a pinch of salt will make the oats like glue.

Forgetting To Stir

  • Stirring breaks up the bubbles that build up. Bubbles can cause a messy explosion and loss of your breakfast.

Not Cooking The Oats Long Enough

  • Be sure to follow the cooking guidelines. Undercooked oats are hard, chewy, and not enjoyable.

What Are Some Other Uses For Oats?

  1. The starch in oatmeal is used as glue in many industries.
  2. Oat straw is used as bedding for cattle and horses because it’s so soft.
  3. Oats can be used as a replacement for breadcrumbs. Especially in meatloaf, meatball, and as a coating for chicken and veal.
  4. Do a facial scrub. Use 1 teaspoon each of oat, honey, and yogurt for an all-natural, soothing face cleanser.
  5. For aches and pains, make a homemade heating pad. Simply sew together two pieces of soft cloth, leave a small area open to drop in the oats, sew shut, and microwave for a minute or so.
  6. Use oats to treat acne. Cook it up and let it cool. Apply it to the affected area and let it sit for several minutes. Rinse.
  7. Oats absorb odors. Like baking soda, if you place an open container in your fridge it will help neutralize any smells. Some people use the flakes in ashtrays as well.
  8. Turn it into clay. Old oatmeal can be turned into safe clay. Combine one cup of oats with flour and some water. It’s only good for about 12-16 hours, then it hardens.
  9. This grain is garden friendly. Sprinkle some flakes around your garden to give your plants some extra iron.
  10. Clean up oil spills in the kitchen. Just sprinkle some dry oats on the spill and let it sit. The oats will soak up the oil, making cleaning up much easier.
