Read More: Nutritional Information on Types of Flour
For consistency, nutritional values are generally discussed per 100 grams (approximately 3.5 ounces or a scant cup, though cup measurements vary by flour density) unless otherwise specified. It’s important to note that exact nutritional figures can vary by brand, processing methods (e.g., enriched vs. unenriched), and specific crop variations.
Wheat Flour (Contains Gluten)
Wheat flours are a cornerstone of baking worldwide, prized for their gluten-forming proteins that provide structure and elasticity to baked goods. The nutritional content, particularly protein and fiber, varies significantly based on how the wheat kernel is milled.
All-Purpose Flour
The versatile workhorse of the kitchen, all-purpose (AP) flour is a blend of hard and soft wheats, with a moderate protein content, typically ranging from 10% to 12%.
- Protein: Around 10-12g. This protein (gluten) provides structure for a wide variety of products, from cookies and cakes to breads and pastries.
- Fiber: Typically low, around 3g, as the bran and germ are removed during milling. Enriched versions have B vitamins (thiamin, niacin, riboflavin, folic acid) and iron added back.
- Carbohydrates: Predominantly starch, around 73-76g.
- Fats: Low, around 1g.
- Key takeaway: A versatile flour, but lower in fiber and micronutrients unless enriched. Its moderate protein is a compromise for various baking needs.
Bread Flour
Milled from hard wheat varieties, bread flour has a higher protein content than AP flour, generally between 12% and 14%.
- Protein: Higher, around 12-14g. This increased gluten potential is ideal for yeast breads, providing strong structure and chewiness.
- Fiber: Similar to AP flour (around 3g) if refined. Whole wheat bread flour will have significantly more.
- Carbohydrates: Around 70-73g.
- Fats: Low, around 1-1.5g.
- Key takeaway: Its high protein content is its defining nutritional and functional characteristic, essential for bread structure.
Pastry Flour
Pastry flour sits between AP flour and cake flour in terms of protein, typically 8-10%. It’s made from soft wheat.
- Protein: Lower, around 8-10g. This results in a more tender crumb, suitable for pastries, pie crusts, and cookies.
- Fiber: Low (around 3g) in its refined form.
- Carbohydrates: Around 75-78g.
- Fats: Low, around 1g.
- Key takeaway: Lower protein for tender baked goods; nutritionally similar to other refined wheat flours.
Italian Flours (e.g., “00” Flour)
Italian “00” (Tipo Doppio Zero) flour is very finely milled and can vary in protein content depending on the wheat used and its intended purpose (e.g., for pasta or pizza). Protein can range from around 9% to 12% or higher.
- Protein: A 30g serving of one organic Tipo “00” flour shows 3g of protein (10%). Other sources indicate “00” flour for bread or pizza can have 11.5-13% protein.
- Fiber: Generally low, around 0.5g per 30g (approx 1.7g per 100g) for some types, due to its fine milling and often being made from the endosperm.
- Carbohydrates: Around 23g per 30g (approx 76g per 100g).
- Fats: Low, around 1g per 30g (approx 3.3g per 100g for some types, though often lower around 1g).
- Key takeaway: Known more for its fine texture than a specific nutritional advantage over other refined flours. Protein varies by its intended use (pasta, pizza, bread).
Cake Flour
Cake flour has the lowest protein content of the wheat flours, typically 7-9%. It’s finely milled from soft wheat.
- Protein: Very low, around 7-9g (some brands may be around 10%). This minimizes gluten development, leading to very tender, soft cakes with a fine crumb.
- Fiber: Low (around 3g) as it’s a refined flour.
- Carbohydrates: Around 77-80g.
- Fats: Low, around 1g.
- Key takeaway: Lowest in protein for maximum tenderness in cakes; nutritionally similar to other refined flours.
Self-Rising Flour
This is essentially all-purpose flour with baking powder and salt already added.
- Protein: Around 8.5-10.5g, similar to or slightly less than AP flour due to the added ingredients.
- Fiber: Low, around 3g.
- Carbohydrates: Around 74-76g.
- Fats: Low, around 1g.
- Minerals: Notably higher in sodium due to the added salt and leavening agents (which often contain sodium). For example, one cup (approx 125g) can have over 1500mg of sodium. Also often enriched with calcium and phosphorus from the baking powder.
- Key takeaway: Convenient for recipes specifically calling for it, but be mindful of the high sodium content.
Whole Wheat Flour
Made by milling the entire wheat kernel (bran, germ, and endosperm), whole wheat flour is nutritionally superior to refined wheat flours.
- Protein: High, around 13-15g. While protein is high, the bran particles can interfere with gluten development, sometimes resulting in denser baked goods.
- Fiber: Significantly higher, around 10-12g. This aids digestion, helps regulate blood sugar, and promotes satiety.
- Carbohydrates: Around 70-72g, but a larger portion is complex carbohydrates and fiber.
- Fats: Higher than refined flours, around 2-2.5g, due to the presence of the germ, which contains healthy unsaturated fats and vitamin E.
- Vitamins & Minerals: Richer in B vitamins, iron, magnesium, phosphorus, and manganese compared to unenriched refined flours.
- Key takeaway: A much more nutrient-dense option than refined flours, offering significant fiber, vitamins, and minerals.
Is whole wheat/grain flour the only option?
The whole wheat/grain version is indeed better for your health as it is richer in protein and contains more fiber, vitamins, minerals, and other nutrients compared to regular white flour. While it’s beneficial to use as much whole wheat/grain versions as possible, it can be challenging to completely replace regular white flour in the kitchen. One of the main reasons for this is that whole wheat/grain flour has lower gluten-forming abilities due to the presence of bran, which can cut gluten strands. This makes it harder to achieve lofty breads (unless you use specialized whole wheat bread flour designed for better gluten development). That’s why many recipes that call for whole grain versions also require combining all-purpose or bread flour to prevent the pastries from becoming dense and underdeveloped. However, there’s good news about white flour as well: you can find nutritious white versions, especially those that are unbleached, unbromated, and enriched, that will be healthy in moderate consumption
Semolina Flour
Coarsely milled from durum wheat, semolina is known for its high protein and gluten content.
- Protein: Very high, typically around 13-15g, but some sources indicate up to 21g per cup (which would be higher per 100g than typical durum wheat averages). It provides excellent structure for pasta and some types of bread.
- Fiber: Moderate, around 4-6.5g. Higher than refined AP flour but less than whole wheat.
- Carbohydrates: Around 69-73g.
- Fats: Low, around 1-1.75g.
- Vitamins & Minerals: A good source of B vitamins, especially thiamin and folate (if enriched), and selenium. Also contains iron.
- Key takeaway: High protein content makes it ideal for pasta. Offers more fiber and nutrients than refined white flours.
Durum Flour
Durum wheat is the hardest of all wheat classes and is what semolina is typically made from. Durum flour can also refer to a finer granulation than semolina, but still from durum wheat.
- Protein: High, around 13-14g.
- Fiber: Higher than bread wheat flour, contributing to a lower glycemic index for products like pasta. Durum wheat flour generally has more dietary fiber.
- Carbohydrates: Around 70g.
- Fats: Around 2.5g.
- Vitamins & Minerals: Rich in folate (especially if enriched), lutein (an antioxidant good for eye health, present at about twice the amount as in bread wheat), iron, magnesium, and phosphorus.
- Key takeaway: Offers high protein, good fiber content, and notable micronutrients like folate and lutein. Products made from it often have a lower glycemic index.
Alternative Flours (May Contain Gluten, Non-Wheat)
This category, as per the user’s list, includes flours from grains other than wheat. It’s crucial to note that rye, barley, and triticale do contain gluten, though it’s different from wheat gluten and may be tolerated differently by some individuals (but not by those with celiac disease). “Whole Grain flour” is a broad term; here it will be interpreted as whole grain flours other than wheat.
Rye Flour
Rye flour has a distinctive, tangy flavor and is lower in gluten-forming potential than wheat flour, resulting in denser baked goods.
- Protein: Around 8-10g, but the gluten is less elastic.
- Fiber: Very high, especially in dark rye flour, often ranging from 15-25g. This makes it excellent for digestive health.

- Vitamins & Minerals: Good source of manganese, magnesium, phosphorus, folate, and B vitamins.
- Key takeaway: Offers a good balance of protein and very high fiber, combining some nutritional benefits of wheat and rye.
Whole Grain Flour (Non-Wheat)
This is a general term. When referring to “whole grain flours” other than whole wheat, the nutritional profile will depend on the specific grain used (e.g., whole grain oat, barley, rye, spelt, etc.).
- General Profile: Compared to refined flours, any whole grain flour will be richer in fiber, as it contains the bran. It will also retain more of its natural vitamins and minerals found in the germ and bran, such as B vitamins, iron, magnesium, and antioxidants.
- Protein: Varies by grain (e.g., spelt has moderate to high protein, oat has moderate).
- Fiber: Consistently higher than refined flours.
- Key takeaway: Choosing any “100% whole grain” flour means you get the benefits of the entire grain kernel, leading to increased fiber and nutrient intake.
Gluten-Free Flours
Gluten-free flours cater to individuals with celiac disease, non-celiac gluten sensitivity, or those choosing to avoid gluten. Their nutritional profiles are highly diverse.
Gluten-Free Flour Blends
These are mixtures of various gluten-free flours (like rice, potato starch, tapioca starch, etc.) and often gums (like xanthan gum) to mimic the properties of gluten.
- Nutritional Profile: Highly variable depending on the ingredients. Some blends are primarily starch-based and may be low in protein and fiber, similar to refined wheat flour. Others may incorporate whole-grain gluten-free flours (like brown rice flour, sorghum flour) or nut flours, offering better nutritional value.
- Enrichment: Some blends are enriched with vitamins and minerals.
- Key takeaway: Read labels carefully. Nutritional content varies widely. Aim for blends with whole grains or added protein/fiber if nutrition is a key concern.
