Quinoa can be a healthy part of a diabetic diet. It's a whole-grain food that's high in protein and lower in carbohydrates compared to other grains. Quinoa also contains vitamins, minerals and phytochemicals that might help manage blood sugar levels and blood pressure, according to a study published in 2009 in the "Journal of Medicinal Food."
Quinoa isn't technically a grain, it's a "pseudo-cereal" that's prepared and served as a grain and it has a similar nutritional profile according to the Whole Grains Council. The American Diabetes Association says that whole grains are acceptable for a diabetic diet and lists quinoa as one of the best choices. Quinoa can be prepared and served as a hot cereal, used cold in salads or served as a side dish.
