What are the calories in white rice flour?
White rice flour is made by finely milling polished white rice grains, which have had their bran and germ removed. This results in a fine, white, starchy flour with a mild flavor that is a popular gluten-free alternative to wheat flour. As a pure carbohydrate source, its caloric content is primarily from starch.
According to USDA data, a standard 100-gram serving of unenriched white rice flour contains approximately 366 calories. For those who measure by volume, this translates to about 578 calories per standard cup.
White Rice Flour Nutrition Profile
Based on a 100g serving, the nutritional breakdown is as follows:
- Calories: 366 kcal
- Carbohydrates: 80.1g
- Protein: 5.95g
- Fat: 1.42g
- Fiber: 2.4g
- Sodium: 0mg
How do the calories in brown rice flour compare?
Brown rice flour is made from the whole grain of rice, including the bran and germ. This means it retains more natural nutrients and fiber than its white counterpart, and has a slightly richer, nuttier flavor. Despite the additional components, the caloric difference between brown and white rice flour is quite minimal.
A 100-gram serving of brown rice flour contains approximately 363 calories, just slightly less than white rice flour. The small reduction in calories is due to a slightly lower carbohydrate content, which is compensated for by higher fiber and fat. The extra fiber is beneficial for digestive health and can help maintain stable blood sugar levels.
Brown Rice Flour Nutrition Profile
For a 100g serving, brown rice flour offers the following approximate nutritional values:
- Calories: 363 kcal
- Carbohydrates: 76.5g
- Protein: 7.23g
- Fat: 2.78g
- Fiber: 4.6g
- Sodium: 8mg
Rice Flour vs. Wheat Flour: A nutritional comparison
While often used as a gluten-free substitute, the nutritional profile of rice flour differs from traditional wheat flour in several key aspects beyond just the absence of gluten. Here is a detailed comparison to help inform your cooking and dietary choices.
Calorie Content and Glycemic Index: Per 100g, the calorie count for both rice and wheat flour is very similar. However, white rice flour generally has a higher glycemic index (GI) than whole-grain wheat flour, while brown rice flour's GI can be lower. This means dishes made with white rice flour can cause a faster spike in blood sugar levels.
Protein and Fiber: Whole wheat flour is significantly richer in both protein and dietary fiber compared to both white and brown rice flour. However, the protein in rice flour is considered to have a better balance of essential amino acids, making it more easily utilized by the body.
Fat and Oil Absorption: Rice flour has a slightly lower fat content than wheat flour. A more practical difference is its lower oil absorption rate when frying, meaning deep-fried foods made with a rice flour batter will soak up less oil and have fewer calories.
Vitamins and Minerals: Whole grain wheat typically has higher levels of many minerals, such as iron, magnesium, and potassium, than white rice flour. Brown rice flour, however, is a good source of B vitamins and minerals like manganese.
| Nutrient (per 100g) | White Rice Flour | Whole Wheat Flour | Brown Rice Flour |
|---|---|---|---|
| Calories (kcal) | ~366 | ~361 (for white bread flour) | ~363 |
| Carbohydrates (g) | ~80.1 | ~72.5 (for white bread flour) | ~76.5 |
| Protein (g) | ~5.95 | ~11.98 (for white bread flour) | ~7.23 |
| Fat (g) | ~1.42 | ~1.66 (for white bread flour) | ~2.78 |
| Dietary Fiber (g) | ~2.4 | ~3.4 | ~4.6 |
| Gluten | No | Yes | No |
How can you use rice flour?
Rice flour is an incredibly versatile ingredient, prized for its specific culinary properties. Because it is naturally gluten-free, it is an essential component in celiac-friendly cooking and baking.
- Gluten-Free Baking: It is a foundational ingredient for gluten-free cakes, muffins, and pancakes. For recipes that require more structure, it is often combined with other gluten-free flours, like potato or tapioca starch, along with a binder such as xanthan gum.
- Thickening Agent: Its fine, starchy nature makes it an excellent thickener for sauces, gravies, and soups. It can provide a smooth consistency without affecting the flavor.
- Frying and Battering: Using rice flour as a coating for fried foods results in an exceptionally light and crispy texture that is less likely to become soggy.
- Noodles and Wrappers: It is the key ingredient for making a variety of Asian noodles and dumpling wrappers, giving them their distinctive tender and chewy texture.
Tips for baking and cooking with rice flour
Using rice flour effectively requires some awareness of its unique properties, especially when substituting for wheat flour. Following these tips can help you achieve the best results in your kitchen.
- Use a Blend: When baking, especially for cakes and bread that require a lighter structure, combine rice flour with other starches. A common blend is rice flour, tapioca starch, and potato starch.
- Add Extra Leavening: Due to the absence of gluten, which helps baked goods rise, you may need to increase the amount of leavening agents, such as baking powder or soda.
- Hydrate the Flour: Rice flour absorbs liquid more slowly than wheat flour. For a finer texture, allow your batter or dough to rest for 20-30 minutes before baking to give the flour time to fully hydrate.
- Be Mindful of Texture: White rice flour can sometimes produce a slightly gritty texture in baked goods. Using a very finely ground flour and properly hydrating it can help prevent this.
- Create Crispy Coatings: For the crispiest fried foods, try mixing rice flour with a little cornstarch for an even crunchier batter that holds up well.

Conclusion
Rice flour, whether white or brown, offers a viable gluten-free alternative to wheat flour with a comparable calorie density. The key difference lies in its macronutrient profile, most notably the absence of gluten and the varying fiber content between its refined (white) and whole grain (brown) forms. Understanding these nutritional nuances allows home cooks and bakers to use rice flour effectively, producing everything from light, delicate pastries to wonderfully crispy fried foods. For those managing a gluten sensitivity or simply looking to explore different flavors and textures, rice flour is a healthy and versatile addition to the pantry.
