Though technically a seed and not a grain, quinoa is often included in lists of gluten free grains because that is how it is used. Often described as an ancient grain, quinoa cooks up into tender morsels that work well in side dishes and salads.
If you’re looking for something new to add to your gluten free food repertoire, quinoa deserves your consideration. Keep reading to learn more about this food and the health benefits it provides.
What is Quinoa, Anyway?
As we’ve already mentioned, quinoa is not technically a grain, nor is it a cereal grain. Quinoa is the seed of a broadleaf plant in the amaranth family known as Chenopodium quinoa. Also related to spinach, quinoa is a pseudocereal and it originated in the Andean region of South America. This plant was domesticated for human consumption over 3,000 years ago, though archaeological evidence suggests that it was used to feed livestock between 5,000 and 7,000 years ago.
The Basics of Quinoa Nutrition
Because it is used primarily as a gluten free carbohydrate, you may be surprised to learn that quinoa is actually a good source of complete protein – it is one of the rare plant foods that carries this label. A complete protein is simply a food that contains all 20 amino acids, including the 10 essential amino acids that your body can’t produce on its own. It may not offer quite the same protein levels as animal products like beef or chicken, but it is an excellent addition to a vegan or vegetarian diet.
In addition to being a source of complete protein, quinoa is rich in a variety of other nutrients. A one-cup serving of cooked quinoa contains about 222 calories with 4 grams of fat, 39 grams of carbohydrate, 8 grams of protein, and 5 grams of fiber. Quinoa is low in sodium but contains a significant amount of key nutrients like manganese, magnesium, phosphorus, folate, copper, iron, thiamine, zinc, potassium, selenium, and various B vitamins.
What Are the Health Benefits of Quinoa?
Technically speaking, there are about 120 different varieties of quinoa grown throughout the world. In grocery stores, however, you’ll probably only find the top three most popular: white quinoa, red quinoa, and black quinoa. White quinoa cooks up into tender grains whereas red quinoa tends to retain its shape and grain-like texture. Black quinoa has a unique earthy flavor and takes longer to cook than the other two.
So, what kind of health benefits does quinoa have to offer?
One of the most important benefits of quinoa is that it is completely gluten free and therefore safe for people with celiac disease, wheat allergies, and gluten intolerance. Not only is it a gluten free grain alternative, but it is a nutritious one at that. Compared to rice (a staple of many gluten free diets), quinoa is much higher in protein, iron, calcium, and fiber. In fact, the fiber content of quinoa is instrumental in many of its health benefits.
The combination of insoluble fiber and protein in quinoa means that it offers increased satiety over other grains. It is also rich in manganese, a nutrient that influences hormones and digestive enzymes to help your body digest and utilize the food you eat more efficiently.
In addition to being rich in nutrients, quinoa is also an excellent source of antioxidants – this is one of the many reasons it is considered a superfood. Antioxidants protect the body against free-radical damage and may also have a protective effect against cancer. One of the nutrients that offers this anti-cancer benefit is called saponin and it has been shown to cause cell death in some of the most aggressive forms of cancer including glioblastoma, leukemia, and lymphoma. Lunasin is another anti-cancer nutrient found in quinoa and it has the power to break apart and kill cancer cells while leaving healthy cells unharmed.
Another health benefit quinoa has to offer is related to its anti-inflammatory properties. Quinoa is rich in heart-healthy, anti-inflammatory fats such as oleic acid and alpha-linolenic acid (ALA). ALA, in particular, has been shown to reduce both cholesterol and blood pressure levels and, in doing so, reduce the risk of death from heart attack. Three other nutrients found in quinoa that have been shown to support heart health are butyrate, magnesium, and potassium.
As if these health benefits weren’t enough, quinoa has also been linked to improved digestion and a healthy microbiome, increased bone strength, and a reduced risk for diabetes. Its antioxidant content has also been shown to reduce the risk for myriad chronic diseases.
