Health Benefits of Quinoa

Quinoa's health benefits are hard to overlook and will make you want to start eating more of it. With its highly enriched nutritional profile, adding quinoa to your diet can improve your health in the following ways.

Might Contain Anti-Cancer Properties

Quinoa's bioactive compounds—phenolic compounds, polysaccharides and saponins—may have anti-inflammatory and antioxidative effects, according to a 2021 study published in Food Frontiers. Laboratory studies on polysaccharides, in particular, suggest that these components may help protect cellular health and prevent certain types of cancer, such as liver and cervical cancers. However, more research is needed to confirm this in humans.

May Reduce Inflammation

Polysaccharides and saponins aren't the only antioxidant compounds found in quinoa. This grain also contains flavonoids and polyphenols. The antioxidant properties of these compounds may help protect your cells from oxidative damage and reduce inflammation, according to a 2023 review published in Antioxidants.

Can Help Regulate Blood Sugar

The nutrients in quinoa may be beneficial in regulating blood sugar. In a small 2022 study published in Nutrients, participants over 65 with blood glucose levels between 100 and 125 mg/dL consumed quinoa for four weeks—the results indicated a significant reduction in glucose and slight weight loss. The researchers suggest that eating quinoa to replace other complex carbohydrates may be a preventive measure against type 2 diabetes.

Protein and fiber contribute to quinoa's low glycemic index. Phenolic compounds are also present, slowing carbohydrate digestion to prevent a high post-meal glucose spike.

May Smooth Digestion

As mentioned above, quinoa is packed with fiber, a critical nutrient for healthy digestion. Consuming quinoa may also increase healthy bacterial growth in the gut microbiome, since fiber nourishes those beneficial bacteria.

May Lower Cholesterol

People at risk for heart attack, cardiovascular disease and stroke can benefit from eating more quinoa to help manage their cholesterol levels. The fiber content in quinoa may help reduce LDL cholesterol levels.

Is Suitable for Celiac Disease

Awareness of celiac disease and gluten intolerance has become more prevalent. For those following a strict gluten-free diet, quinoa has proven to be a good alternative to gluten-containing grains.

Quinoa seeds contain gluten-free protein with ample amino acids, according to a 2020 paper published in Proceedings. Malting the quinoa seeds—a process involving soaking and germination—enhances nutrient absorption. The amino acids, simple sugars and fatty acids released during malting move more easily through your intestine when consumed.

May Prevent Anemia

People who do not eat enough iron-rich foods, experience chronic blood loss or routinely do rigorous exercise may have iron deficiencies. Iron-deficiency anemia often leads to symptoms like fatigue, paleness, dizziness, brittle nails and weakness.

It is estimated that 25% of people worldwide have anemia—50% of which occurs from iron deficiency, according to a 2023 entry in StatPearls. Quinoa may help compensate for this nutrient in vegans and vegetarians; dietary sources of iron—like quinoa, leafy greens and red meat—are conducive to building up this essential mineral in the body.

Quinoa Nutrition Facts

Quinoa has been around for a long time. According to a 2020 review published in Foods, the South American Andes indigenous people cultivated quinoa as far back as 5000 BCE to 3000 BCE. The Inca civilization deemed it sacred. Quinoa cultivation and use waned in urban areas during the Spanish colonial period, but many quinoa varieties—including white, red and black—continued to be grown on communal lands. Worldwide production and consumption has increased hugely in recent decades due to quinoa's crop hardiness and nutritional value.

The prevalence of omega-3 fatty acids, amino acids and protein has put a spotlight on quinoa, according to a 2022 study published in Nutrients. Experts have even gone so far as to suggest quinoa could deliver a solution to the world's malnutrition crisis.

Your body receives the following nutrients from a 1-cup serving of cooked quinoa, per the USDA:

  • Calories: 222
  • Total Carbohydrates: 39g
  • Dietary Fiber: 5g
  • Total Sugars: 2g
  • Protein: 8g
  • Total Fat: 4g
  • Saturated Fat: <1g
  • Sodium: 13mg

Quinoa is a nutritious choice for people looking for plant-based protein sources—it's a complete protein, containing all nine of the essential amino acids. Plus, its dietary fiber may improve your digestion, and both fiber and protein can help make you feel more satiated than other grains.

People who eat quinoa also consume a healthy dose of manganese, folate, zinc, iron, phosphorus, magnesium and vitamin B1.

How to Cook Quinoa

Quinoa is a quick-cooking grain, and it's easy to prepare. As a rule, you should use 1 3/4 to 2 cups of water or broth for 1 cup of quinoa—equivalent to four servings. Rinse the quinoa in a strainer to remove its bitter coating.

Then, add the quinoa, liquid and 1/4 teaspoon salt—if you opt to use it—to a medium saucepan and bring to a boil. Turn the heat down to low and cover the pan. Allow the quinoa to simmer until the liquid is absorbed and the grains look like they've popped open, about 15 minutes.

Once done, remove the saucepan from the burner and allow the quinoa to stand, covered, for 10 minutes. Fluff with a fork before serving.

How to Add Quinoa to Your Diet

Quinoa's versatility makes it easy to add to meals, including breakfast. You can store a quinoa, oat and chia seed mix in an airtight container for warm and hearty oatmeal. Just one serving of our Quinoa & Chia Oatmeal Mix contains 6 grams of fiber to start your day. Quinoa is also an excellent filler for stuffed peppers, such as Quinoa-Stuffed Peppers—just prepare quick-cooking quinoa beforehand to speed things up.
