Quinoa Types, Nutrition Facts, Health Benefits, Side Effects

What Is Quinoa?

Most people think that quinoa is a grain, but it is actually the seed of the green leafy plant of the genus Chenopodium Quinoa. It is also a member of the spinach and beet family. It is a “fake” grain because its nutritional content and its manner of consumption are the same as grains.

There are more than 120 different species of Chenopodium Quinoa, consisting of different seed colors. However, only three main varieties are commonly grown. The most common ones being white, red and black quinoa.

Studies have found that although white quinoa is more delicious, the vitamin E content of red quinoa and black quinoa is almost twice that of white quinoa. Black quinoa has the lowest fat content, but it also has the highest omega-3 fatty acids and carotenoids.

Quinoa Types

1. White quinoa

It is the most common variety. Like its color, white quinoa usually has a milder taste than the other varieties. The texture is softer after being cooked. Therefore, many people use it as a substitute for rice.

2. Red quinoa

Red quinoa is similar to brown rice. It is more nutritious than traditional white quinoa. It has a richer taste and is chewier than other varieties. Red quinoa maintains a good shape during the baking process, so it is great for making baked goods and mixing in salads.

3. Black quinoa

The texture of black quinoa is firmer and the taste is sweeter. It is an ideal ingredient for making sweets (such as oatmeal and muffins).
