Quinoa vs Oatmeal: What’s The Difference?
Quinoa has become more popular in recent years while oatmeal is known by almost everyone for a long time. For this reason, some people aren’t familiar with quinoa and what it actually is.
Therefore, let’s answer a common question, are quinoa and oatmeal the same?
Quinoa is not the same type of grain as oatmeal. Quinoa is the seed from a Chenopodium quinoa plant, while oatmeal is extracted from grass and is considered a whole grain.
Quinoa is described as a whole grain because it is consumed like one. However, it’s more accurately labeled as a “pseudo-cereal.”
Pseudo-cereals are foods taking on the qualities of whole grains but botanically do not match the definition of a whole grain. You cook and eat them like you would a whole grain, but they are not derived from grasses.
There are three common types of quinoa:
White is less bitter and all three have slightly different cooking times and chewiness.
Because oats are the primary ingredient in oatmeal, the different types of oatmeal come down to how the oat is flattened and sliced.
There are four main types of oats:
- Rolled: Rolled oats are the classic oats used in oatmeal. These are also called regular or old-fashioned oats.
- Steel-cut: Oatmeal made from steel-cut oats is typically chewier and heartier. You can also use these oats as a substitution for traditional rice dishes, like risotto.
- Stone-ground: Stone-ground oats make creamy oatmeal.
- Quick: Quick oats, often called instant oats, are thinner rolled oats. These are often used in instant oatmeal and microwavable versions because the oats don’t take as long to cook.

Quinoa and Oatmeal Glycemic Index
Knowing the glycemic index of food is important especially if blood sugar levels are a concern. Avoiding blood sugar spikes is an important part of consuming healthy food.
The Glycemic Index (GI) is a scale measuring how fast a particular food raises the blood sugar in the blood 3. Blood sugar spikes can lead to health complications with the heart, nerves, kidneys and eyes 4.
Foods on the GI scale are categorized as:
- Low-GI foods: 55 or under
- Medium-GI foods: 56-69
- High-GI foods: 70 or over
How blood sugars levels are affected:
- Foods with a glycemic index 70 or more cause a quicker spike in blood sugar levels.
- Foods with a glycemic index 56 to 69 cause a moderate spike in blood sugar levels.
- Foods with a glycemic index 55 or less cause a slow spike in blood sugar levels.
Having more knowledge of the glycemic index of food and how it raises blood sugar, many people ask, does quinoa or oatmeal have a higher GI?
Quinoa has a lower GI than oatmeal. Rolled oats have a GI of 55. Instant oatmeal has a GI of 79. Steel-cut oats have a low GI under 55. Quinoa has a GI of 53.
The complex carbohydrates in quinoa digest slowly and enter the bloodstream slowly. This combination helps to prevent harmful blood sugar spikes.
Steel-cut oats have a lower GI because they are the least processed. Rolled oats are a little higher because they’ve been partially cooked. Quick oats have been steamed and rolled into thinner pieces to cook quicker. This process increases their GI.
Find out if grits or oatmeal has the better GI in my article, Grits vs Oatmeal: Which is Better? A Complete Comparison.
Quinoa vs Oatmeal: Satiety Index
Satiety is a term used to explain the feeling of being full and the loss of appetite which occurs after eating food. The satiety index is a scale showing how full a person feels after eating a certain food.
The satiety index was developed in 1995 from a study which tested 38 foods. The foods were ranked how they satisfied a person’s hunger. Foods scoring under 100 are considered less filling and foods scoring above 100 are considered more filling 5.
The table below shows the satiety scores of oatmeal and a few other filling food.
|Food||Satiety Index Score|
Compared to white bread at 100%, it turns out oatmeal is 209% more satiating. Additionally, it is more satiating compared to wholemeal and grain bread as well.
Of all the 38 foods, oatmeal scored the fourth highest only beat by oranges, ling fish and boiled potatoes.
Unfortunately, quinoa was not one of the 38 foods tested. A study in 2005, by the University of Milan, tested the satiety of quinoa, oats and buckwheat compared to eating rice. All three had a higher satiating efficiency than rice.
High satiety food like oatmeal and quinoa are likely to have a high satiety score for the following reasons:
- High in protein.
- High in fiber.
- High in volume (foods containing a lot of water or air).
- Low in energy density (foods low in calories for their weight).
Oatmeal seems to fit into all four listed above.
- Oatmeal contains 7.9 grams of protein per 3/4 cup.
- Oatmeal provides 6.1 grams of fiber per 3/4 cup.
- Oatmeal weighs a good amount when prepared in relation to its calories.
- Oatmeal cooked is only 71 calories per 100 grams.

How To Store Quinoa and Oatmeal
Whichever you choose or have on hand, proper storage is crucial. How you store quinoa, oatmeal, vegetables or fruit can affect how long they last before going bad and how they taste. Therefore, how do you store quinoa?
The best way to store unopened or opened quinoa is to keep it in a cool, dry place away from the sun or indirect heat. Opened quinoa should be tightly covered and sealed in its original container, glass container, plastic container or a resealable bag. Opened, uncooked quinoa does not have to be refrigerated.
Store cooked quinoa in a sealed container in the refrigerator up to 3-5 days. Do not leave cooked quinoa out of the refrigerator for more than two hours.
How do you store oatmeal?
Store unopened dry oatmeal in a cool, dry place away from the heat and sun. Opened oatmeal should be tightly covered in its original container, glass or plastic container or resealable bag. Opened, uncooked oatmeal does not have to be refrigerated.
Opened oatmeal should be stored up to one year. Always check the dates on the packaging. Typically, the “best if used by date” is a quality suggestion 6.

Quinoa and Oatmeal Health Benefits
The nutrients provided by quinoa and oatmeal are similar, just in different amounts provided per serving. Therefore, the benefits are the same but one of the two may be better than the other.
Of the six B vitamins listed below, quinoa provides a higher percentage of all of them compared cooked oatmeal.
The B vitamins provided include the following:
- B1 (thiamin)
- B2 (riboflavin)
- B3 (niacin)
- B9 (folate)
B vitamins help support the following:
- Brain function.
- Cardiovascular disease.
- Nerve function.
- Red blood cells.
- Energy levels.
A lack of B vitamins has been associated with oxidative stress and neural inflammation. In a study released in 2018 32 healthy adults were given B vitamin supplementation for six months. The results indicated preliminary evidence B vitamin supplementation reduced oxidative stress and inflammation 7.
- Quinoa contains 2.8 grams of fiber per 100 grams.
- Oatmeal contains 1.7 grams of fiber per 100 grams.
Both foods are high in soluble fiber, which is helpful for many reasons 8. What makes fiber soluble is it dissolves in water.
Soluble fiber is known for the following:
- Decrease the risk of diabetes by managing the blood glucose levels.
- Helps avoid constipation and have a more regular stool.
- Help overall digestive health.
- Aids greatly in weight management because it allows you to feel full faster and eat less.
Check out the differences between red and white quinoa in my article, Red Quinoa vs White Quinoa: What’s The Difference?
- Quinoa contains 17 mg of calcium per 100 grams
- Oatmeal contains 9 mg of calcium per 100 grams
Calcium is important for the heart and blood pressure. Harvard Health reports calcium helps maintain blood pressure by helping in the controlling of the relaxing and tightening of blood vessels 9.
Calcium also helps the following:
- Help the muscles to function properly.
- Helps nerve function.
- Build and maintain strong bones.
- Quinoa contains 64 mg of magnesium per 100 grams
- Oatmeal contains 27 mg of magnesium per 100 grams
Magnesium helps keep blood pressure levels stable and balanced. Recent scientific research examined previous studies and concluded magnesium supplementation decreased systolic and diastolic blood pressure 10.
Magnesium helps control the following:
- Blood sugar
- Blood pressure
- Nerve function
One reason many people supplement with magnesium in the evening is because it helps calm the whole body including blood vessels.
In the heart and muscles, magnesium competes with calcium to help the muscles relax after contracting. When the body is low in magnesium, calcium can over stimulate the heart muscle’s cells causing a rapid or irregular heartbeat 11.

- Quinoa contains 152 mg of phosphorus per 100 grams
- Oatmeal contains 77 mg of phosphorus per 100 grams
Phosphorus has been shown in scientific studies to help with the following:
- Help the body store and manage energy.
- Muscle contraction.
- Muscle recovery.
- Help the kidneys remove waste.
- Promote healthy nerve conduction.
- Promote teeth and bone strength.
Find out how white quinoa compared to black quinoa in my article, White Quinoa vs Black Quinoa: What’s The Difference?
- Quinoa contains 172 mg of potassium per 100 grams
- Oatmeal contains 70 mg of potassium per 100 grams
Potassium helps the body get rid of excess sodium reducing fluid build-up. These help keep systolic and diastolic blood pressure lower 12.
According to Harvard Health, a number of studies have shown a connection between low potassium levels and high blood pressure 13. The more potassium, the more sodium your body will lose.
Consuming too much sodium or not enough potassium throws off the delicate balance the kidneys need to remove the excess water 14.
- Quinoa contains 1.49 mg of iron per 100 grams
- Oatmeal contains 0.90 mg of iron per 100 grams
Much higher in iron than other grains, oatmeal is an excellent choice if you need to get your daily value of iron. Iron is essential in the creation of red blood cells and is a necessary part of any healthy diet.
Iron is also vital for growth and development, as some hormones need iron to be appropriately balanced.
Quinoa and oats are naturally gluten-free and might be a great substitute to other gluten-heavy items of a similar taste. Even those who don’t have a completely gluten-free diet may benefit from cutting down on their gluten.
Recently it has been discussed many more people have at least a small amount of gluten intolerance and are unaware of it. Having less gluten in your diet is a good choice for most.
Important: Although oats and quinoa are gluten free, they may come in contact with gluten-containing grains in storage or during transportation. Most of the Quaker oat products have solved this issue and label those products gluten free. Always check the label of your oatmeal or quinoa to determine if its gluten free.
