Quinoa is a whole grain that is rapidly growing in popularity due to its many health benefits.
Although people can cook and eat quinoa seeds in a similar way to most grains, the quinoa plant itself is more similar to beetroots and spinach. People can eat both the seeds and leaves of this versatile, nutritious plant.
Farmers cultivate over 120 different types of quinoa. However, the most common versions available in grocery stores are white, red, and black quinoa.
In this article, we explain the evidence-based health benefits of quinoa. We also look at the nutritional content of quinoa and how to add it to the diet.
Below are some of the health benefits of regularly consuming quinoa.
A plant-based source of protein
People following a plant-based diet need to find nonanimal sources of protein to ensure they are getting enough.
One cup of cooked quinoa weighing 185 grams (g) provides 8.14 g of protein.
This makes quinoa an excellent dietary choice for people following a vegetarian or vegan diet.
Quinoa, unlike many other grains, is also
High fiber content
According to the Academy of Nutrition and Dietetics, consuming enough fiber can help reduce the risk of several health conditions, including constipation, high cholesterol, high blood pressure, and diverticulosis.
Diets rich in fiber may also promote a healthy weight. This is because foods high in fiber help people feel fuller for longer, potentially reducing their overall intake of food.
A source of antioxidants
Quinoa is a good source of antioxidants compared with other common grains in a gluten-free diet. Most gluten-free products consist of corn, rice, or potato flour. These generally provide
New studies regularly emerge that confirm the health benefits of adequate whole grain intake and their antioxidant capacity.
Helps meet manganese requirements
Manganese is essential for development and metabolism. This element also works alongside many enzymes in the body to support their function.
Good source of iron
Iron is necessary for a range of processes in the human body. It is, for example, an essential part of hemoglobin. This compound carries oxygen in the blood, supporting energy and cell function throughout the body.
Adequate iron intake also supports healthy connective tissue and muscle metabolism.
A source of folate
Folate is an essential B vitamin that plays a key role in the formation of DNA. It is particularly important that women obtain enough folate during pregnancy to reduce the chance of neural tube defects in their babies, according to the Office of Dietary Supplements (ODS).
Getting enough dietary folate might also reduce the risk of several cancers and depression.
Pregnant women may only be able to get enough folate by taking folic acid supplements. However, consuming more folate in the diet can reduce the risk of deficiency. Quinoa provides a good proportion of a person's daily folate value.
One cup of cooked quinoa contains 118 mg of magnesium. Although the daily recommended amount increases with age, quinoa is a good source of the mineral.
Magnesium is essential for the function of more than 300 enzymatic reactions and is present in every cell of the body.
The ODS suggest that low levels of magnesium have possible links to the following health concerns:
However, more research is necessary to confirm the effects of dietary magnesium on these conditions.
Contains quercetin and kaempferol
Quinoa contains the plant compounds quercetin and kaempferol.
Plant experts classify quinoa as a pseudocereal, not a grain. This means that it is a nongrassy plant that food producers can use in much the same way as cereals and grains. It also has a similar nutritional profile.
Manufacturers can mill or grind the seeds of pseudograins into flour, as with other grains and cereals.
Nutritionally, quinoa is a whole grain. Whole grains include the entire grain seed without removing any of its parts.
Whole grains provide essential vitamins, minerals, and fiber that might otherwise not be available after removing parts of the grain.
Quinoa is naturally gluten-free.
One cup of cooked quinoa provides:
- 222 calories
- 8.14 g of protein
- 5.18 g of fiber
- 3.55 g of fat, of which 0.42 g is saturated
- 39.4 g of carbohydrate
Quinoa is highly nutritious and can provide a large portion of a person's daily requirement or adequate intake for several important nutrients, including:
|Nutrient||Percentage of daily requirement for adults|
|Magnesium||At least 28.10%, depending on sex and age|
|Manganese||27.43% for males, and 25.05% for females|
|Iron||34.5% for males, and 15.33% for females|
|Zinc||18.36% for males, and 25.25% for females|
|Riboflavin||18.55% for males, and 10% for females|
|Vitamin B-6||Around 17.54%, depending on age|
The same amount of quinoa contains traces of vitamin E, vitamin B-3, and calcium.
Quinoa contains bitter tasting compounds called saponins that keep insects away without the need of pesticides. They are especially concentrated in the outer coating of quinoa.
Manufacturers can easily remove saponins by
Although producers of most packaged quinoa have already removed most of the saponins, people may wish to give it an extra rinse before consuming it.
It is easy to incorporate quinoa into the diet. People can use it instead of rice in any recipe. Its small grains cook to tender in as little as 15 minutes.
Quinoa has a subtle nutty taste that makes it a very versatile ingredient. It can play a role in baking or as a breakfast grain. Quinoa also works well in hot side dishes, cold salads, and burgers.

Are any other pseudograins available that can match quinoa in terms of nutritional impact?
Although quinoa is a highly nutritious carbohydrate option, there are other pseudograins that provide similar health benefits. Buckwheat, teff, and amaranth are nutrient dense pseudograins that people can use as substitutes for quinoa in recipes. Not only are these pseudograins filling and delicious, but each of them offers a number of impressive health benefits.
Buckwheat is packed with nutrients including magnesium and manganese, and its consumption may boost heart health and promote blood sugar control. Teff is an excellent source of plant-based protein, providing
Amaranth is another protein-packed pseudograin known for its concentration of powerful antioxidants. Antioxidants present in amaranth may help promote health in many ways, such as by protecting cells against free radical damage and reducing the risk of oxidative stress-related diseases.
A person can try using one of these pseudograins if they do not like the taste of quinoa, or if they simply want to add more healthful carbohydrate options to their diet.Katherine Marengo LDN, R.D.
