Quinoa vs. Buckwheat: Which Grain Offers Better Nutrition?
Translated & summarized from Maariv by baba
Dr. Maya Rozman compared quinoa and buckwheat, finding both are healthy alternatives to common grains. Quinoa offers slightly more protein, while buckwheat is lower in calories per cooked weight. Both have similar carbohydrate and fiber content and impact blood sugar moderately. Rozman suggests alternating between the two based on preference and dietary goals, as both can fit into a healthy eating plan, including for weight loss.

- Quinoa offers slightly more protein (4.4g/100g cooked) than buckwheat (3.4g/100g cooked).
- Buckwheat is lower in calories (92 kcal/100g cooked) compared to quinoa (120 kcal/100g cooked).
- Both quinoa and buckwheat have similar carbohydrate and fiber content.
- Both grains impact blood sugar levels moderately.
- Quinoa contains more fat, primarily unsaturated, than buckwheat.
- Both are considered healthy and can be part of a balanced diet.
Dr. Maya Rozman, a medical professional, has analyzed the nutritional differences between quinoa and buckwheat, two popular alternatives to rice, pasta, and couscous. While both are considered healthy, they offer distinct advantages. Quinoa contains slightly more protein, with about 4.4 grams per 100 grams cooked, compared to buckwheat's 3.4 grams. Both are noted for their relatively good amino acid profiles, including lysine, and are sometimes called "complete proteins" because they contain all essential amino acids. However, Rozman clarifies they are not direct substitutes for protein-rich foods like tofu, eggs, or legumes.
In terms of calories, buckwheat has a slight edge, with approximately 92 calories per 100 grams cooked, versus quinoa's 120 calories. Carbohydrate and fiber content are very similar between the two, with around 20-21 grams of carbs and 2.7-2.8 grams of fiber per 100 grams cooked. Quinoa does contain more fat, primarily unsaturated, at about 1.9 grams compared to buckwheat's 0.6 grams. The water absorbed during cooking affects these 100-gram values, so pre-cooking differences may vary.
Both quinoa and buckwheat impact blood sugar levels due to their carbohydrate content, though studies suggest a moderate glycemic response. Neither is definitively superior for blood sugar balance. Both grains also provide essential minerals like magnesium and iron. Buckwheat has an advantage due to its content of rutin, a flavonoid antioxidant, though amounts vary by buckwheat type and processing. Quinoa also contains antioxidants like quercetin.
Rozman explains that the common brown buckwheat is roasted, giving it a nuttier flavor and firmer texture, while green buckwheat is unroasted, milder, and suitable for porridge or sprouting. The roasting process can alter some nutrients, but the impact depends on processing conditions. Quinoa seeds are often washed before cooking to remove saponins, which can impart a bitter taste, though many products are now pre-washed.
Ultimately, Rozman concludes that both quinoa and buckwheat are good choices for a healthy diet, offering slightly different benefits. Quinoa provides a bit more protein, while buckwheat is lower in calories per cooked weight. They can be alternated based on taste and preparation, and both can be incorporated into weight-loss plans.
