Rice, oats, wheat, quinoa, bread, pasta, flour and other grain foods: nutrition, processing, storage and cooking.
Instant yeast usually starts a little faster because its smaller particles rehydrate quickly and can be mixed right into flour. Active dry yeast may take longer to get going, but major baking references allow a 1:1 substitution in most standard doughs.
Oats do not naturally contain the gluten proteins found in wheat, rye, and barley. The practical problem is cross-contact during growing, transport, milling, and packaging. People with celiac disease should choose oats that meet gluten-free requirements rather than assuming every bag of oats is safe.
Whole grain does not mean brown, seeded, or multigrain. A whole grain retains the bran, germ, and endosperm in the same relative proportions as the original kernel, even when it has been milled, cracked, or flaked.
Cooked bulgur usually has fewer calories and much more fiber than refined couscous: about 83 calories and 4.5 g fiber per 100 g versus 112 calories and 1.4 g. Both come from wheat and contain gluten, but bulgur is typically a whole-grain product.
Compared dry, whole wheat and spelt can provide roughly 14–15 g protein per 100 g, oats about 13 g, hulled barley 12–13 g, rye around 10 g, and brown rice about 7–8 g. Cooking adds water and sharply lowers the per-100-gram number.
By dry weight, hulled barley and rye are among the highest-fiber common grains, often around or above 15 g per 100 g. Bulgur and oats commonly provide about 10–13 g, while brown rice is closer to 3–4 g. Processing changes the numbers substantially.
Per 100 g cooked, quinoa is around 120 calories and 4.4 g protein; amaranth about 102 calories and 3.8 g. Quinoa usually has slightly more fiber, while amaranth contributes notable calcium and iron and cooks to a much creamier texture.
Despite its name, buckwheat is not related to wheat and is naturally gluten-free. Cooked groats provide roughly 92 calories, 3.4 g protein, and 2.7 g fiber per 100 g, plus magnesium, manganese, and plant compounds such as rutin.
Millet is a naturally gluten-free cereal that, cooked, provides roughly 119 calories, 3.5 g protein, and 24 g carbohydrate per 100 g. Its cooked fiber content is modest, while dry millet contributes minerals including magnesium, phosphorus, and manganese.
Oats and barley are both beta-glucan-rich grains, but their profiles differ. Dry oats and hulled barley each provide roughly 12–14 g protein per 100 g. Hulled barley can contain much more total fiber, while oats contain more fat and are especially convenient as flakes.
Quinoa, amaranth, and buckwheat are not botanical cereal grains. They are seeds from non-grass plants that are cooked and milled in grain-like ways. All three are naturally gluten-free, with distinct textures and nutrient profiles.
Lentils clearly lead on protein and fiber: per 100 g cooked they provide roughly 9 g protein and 8 g fiber, compared with about 4.4 g and 2.8 g in quinoa. Calories and carbohydrate are much closer, so the two foods play different roles on a plate.
