Quinoa is naturally gluten-free, providing a great alternative to wheat for people with celiac disease or gluten sensitivity. It’s also easy to cook and quite versatile – it can be incorporated into everything from breakfast cereals to salads to main dishes.

1. Quinoa is a Complete Protein

Unlike most plant foods, quinoa contains all nine essential amino acids, making it a complete protein. This means quinoa can help you meet your daily protein needs, especially if you follow a vegetarian or vegan diet. One cup of cooked quinoa provides about 8 grams of protein.

2. It’s Naturally Gluten-Free

Quinoa does not contain gluten, the protein found in wheat, barley and rye that causes issues for those with celiac disease or gluten intolerance. This makes quinoa a safe and nutritious alternative to traditional gluten-containing grains2.

3. Quinoa is High in Fiber

With 5 grams of fiber per cooked cup, quinoa is an excellent source of dietary fiber. Fiber promotes healthy digestion and may help lower cholesterol and blood sugar levels.

4. It Has a Low Glycemic Index

The glycemic index measures how quickly foods raise blood sugar levels. Quinoa has a relatively low glycemic index of 533, meaning it won’t lead to spikes and crashes in blood sugar.

5. Quinoa Contains Antioxidants

Quinoa provides two powerful flavonoid antioxidants, quercetin and kaempferol, which have anti-inflammatory effects in the body. Antioxidants protect cells from damage and promote overall health.

6. It’s a Good Source of Magnesium

One cup of cooked quinoa delivers 30% of the recommended daily intake of magnesium4, a mineral involved in over 300 processes in the body. Magnesium promotes nerve and muscle function, heart health, and blood sugar control.

7. Quinoa May Help Lower Cholesterol

The fiber and magnesium in quinoa may help reduce LDL or “bad” cholesterol levels, decreasing the risk of heart disease. One study found that eating quinoa daily lowered LDL cholesterol.

8. It Contains Omega-3 Fatty Acids

Quinoa is one of the few plant sources of omega-3 fatty acids, which are important for brain health and reducing inflammation. It specifically provides alpha-linolenic acid (ALA).

9. Quinoa Aids Weight Loss

With protein, fiber, and a low glycemic index, quinoa is satisfying and can help you feel fuller longer. This makes it a great food for weight management.

10. Quinoa Has a Nutty, Pleasant Flavor

Quinoa has a light, fluffy texture when cooked and a mild, slightly nutty flavor. The taste is versatile enough that quinoa can be used in both sweet and savory dishes.

11. It’s Easy to Cook

Quinoa only takes about 15 minutes to cook. Simply combine 1 cup quinoa with 2 cups liquid like water or broth and simmer until the germ separates from the seed5.

12. Quinoa Comes in Different Colors

13. It’s Sustainable to Grow

Compared to grains like wheat and rice, quinoa requires less water to cultivate and thrives in poor soil conditions. This makes quinoa a sustainable crop.

14. Quinoa Has Been Around for Thousands of Years

Quinoa was first cultivated in the Andes Mountains of South America as early as 3000 BCE. It was a staple food of the ancient Incas, Aymara, and Quechua civilizations.

15. Most Quinoa Comes from South America

While quinoa is grown in the U.S. and other countries, most commercial quinoa still comes from Bolivia and Peru where it originated.
