Quinoa flakes are naturally very low in calories, are very low in fat, and are cholesterol-free. They are an excellent source of plant-based protein and dietary fibers. One-third a cup of dry quinoa flakes provides about 130 calories and just two grams of fat, and, like all naturally vegan foods, they're completely cholesterol-free. Quinoa flakes also provide a healthy amount of dietary fiber - about 2.5 grams per 1/3 cup, and 4.3 grams of protein. Like quinoa, quinoa flakes are a great source of protein, especially for vegetarians and vegans.
