What is quinoa?

Quinoa or quinoa ( Chenopodium quinoa Willd. ) Is a plant of the Amaranthacae family, native to the Andean regions of the South American continent.

Quinoa is a pseudocereal, that is, a food that is obtained through the seeds of the plant’s flower. The quinoa plant can grow in humid areas and supports temperatures from -4 ° C to 38 ° C. (1)

Due to its wide benefits in terms of nutrients, the FAO and other international organizations recommend including quinoa in meals both as a way to achieve the ideal healthy weight and to reduce hunger in the world.

In 2013, the FAO declared the year of quinoa as a way to promote the cultivation of this type of food and promote healthy eating rules.

1. Does not contain gluten

Quinoa does not contain gluten. About 1% of the world’s population is gluten intolerant. For these people it is extremely important to find alternatives to wheat without being rice. One of the benefits of quinoa is that it is allowed for celiacs.

2. High content of vegetable proteins

The protein content of quinoa is higher than that of any other plant food. Therefore, it is considered the leading plant-based protein food on the market. This is considered one of the most important benefits for vegetarians and vegans.

3. Average glycemic index

Another benefit of quinoa is its medium glycemic index . 150 grams of cooked quinoa has a glycemic index of 50. This is explained due to its high fiber content; about 7% of its weight. Due to this fact, it is considered a recommended food in a diet for type 2 diabetics .

4. High mineral content

100 g of quinoa covers the RDA for manganese, 49% magnesium, 25% iron and 21% zinc (1) . The lack of zinc is one of the most frequent in nutrition since it is a difficult mineral to find.

5. Rich in flavonoids

Quercetin is the main flavonoid in quinoa. This type of molecule is classified as a natural antioxidant. Among other things, one of its benefits is to neutralize the action of free radicals and prevent the development of cancer cells.

6. High in healthy fats

Quinoa contains a healthy fat content equal to 7% of its weight. Like chia seeds , the presence of Omega-3 fatty acids stands out, its content is approximately 80 mg in 100 g of dry cereal.

7. Cooking quinoa is easy

You don’t need to be a kitchen expert to cook quinoa. For each part of quinoa you need two parts of water. Like all shelled grains, it must be soaked and pre-washed with water. One of its benefits in the kitchen is that it is easily adaptable.

As can be seen in the table, quinoa is a very complete food in nutritional terms. Including it in meals leads to a host of health benefits.


The carbohydrates in quinoa are complex carbohydrates . These types of molecules deliver energy slowly and gradually. Something essential for people with a tendency to diabetes or who suffer from other disorders in insulin metabolism. WHO recommends that up to 60% of total calories come from this energy source.


Quinoa is the food with the highest protein content of plant origin. No other cereal or pseudoceral surpasses quinoa in quantity or quality of protein. 200 g of quinoa provides about 28 g of protein, a quarter of the recommended amount of protein per day .


Quinoa is considered a low-fat food. 100 g of quinoa provide only 6 g of fat. Compared to the 30 g that a steak can provide, it is a really low value. The fats in quinoa are fundamentally monounsaturated; a type of fat associated with improved cardiovascular health.

Quinoa vs rice vs wheat

The main difference between quinoa and cereals is its amino acid profile. This pseudocereal contains a high content of essential amino acids : lysine, glycine and tryptophan. Fundamental compounds for the functioning of the nervous and muscular system.

When comparing quinoa to rice, it’s not just about the nutrient content ; but from where they are. In rice the amino acids are concentrated in the husk. When processed industrially, rice loses most of its properties. In the case of quinoa, the amino acids are found in the nucleus by which they are maintained. (1)

If we confront quinoa with wheat, the first thing that should be highlighted is the presence of gluten. Unlike wheat, quinoa does not contain this protein so it is a food allowed on a gluten-free diet .

Other nutritional differences are a higher content of healthy fats and proteins, in quinoa the values ​​are up to 5 times higher. (2)
