Quinoa is a seed often used like a grain and is known for having more protein than many grains. However, it is still high in carbohydrates and not suitable for low-carb or keto eating. Quinoa may be workable in small, measured portions for some diabetic plans, but it must be portion-controlled and balanced with protein and fat.
