Maize Flour vs. Other Common Flours: A Comparison
To put maize flour's nutritional profile into context, it's helpful to compare it to other popular flours like wheat flour. This helps in understanding the best uses for each, especially for specific dietary needs, such as a gluten-free diet.
| Feature | Whole-Grain Maize Flour (per 100g) | Whole Wheat Flour (approx. per 100g) |
|---|---|---|
| Calories | ~361 kcal | ~364 kcal |
| Protein | ~7 g | ~11-12 g |
| Fat | ~4 g | ~2 g |
| Carbohydrates | ~77 g | ~76 g |
| Dietary Fiber | ~7 g | ~11 g |
| Gluten | Gluten-Free | Contains Gluten |
This comparison highlights key differences. While the overall calorie count is similar, wheat flour tends to be slightly higher in protein and fiber, whereas maize flour offers more healthy fats and is naturally gluten-free.
