What is healthier, wheat or oats?
Both wheat and oats have their health benefits.
Both flours are rich in fiber and nutrients.
The choice between the two depends on your nutritional goals and any dietary restrictions.
Wheat Flour
Wheat flour is made from wheat kernels that are ground into a fine powder and contains essential macronutrients and micronutrients that the body needs, such as protein, fiber, calcium, iron, and potassium.
Whole wheat flour is higher in calories and carbohydrates than oat flour, but it also has more protein and fiber.
Oat Flour
Oat flour is made from grinding up oats and as a result has all the same nutrients as rolled oats do.
You can oat flour simply in a blender or food processor by grinding up rolled oats into a fine flour.
It contains 4 grams of protein, 3 grams of fiber, calcium, iron, potassium, and thiamine.
Oat flour has a lower glycemic index score than whole wheat flour, which means it causes a slower rise in blood sugar levels.
Baking Differences
Oat Flour
Oat flour is softer and lighter than wheat flour, so recipes may need larger amounts of oat flour than wheat flour.
Oat flour is generally gluten-free, which means it won't make leavened products without a little help from leavening agents such as baking powder, baking soda, or yeast.
It can be combined with other flours, like whole wheat flour, to make baked goods, such as this vegan banana bread rise.
Texture
Oat flour has a texture that is more similar to whole wheat flour than to refined wheat flour.
It's light and absorbent, making it a great choice for banana bread, energy bars, and flourless pumpkin bread.
Flavor Differences
Oat Flour
Oat flour is naturally a little bit sweeter than wheat flour, which means it adds more flavor to baked goods like muffins, pancakes, and bread.
Whole Wheat Flour
Whole wheat flour has a denser texture and strong flavor, making it a great choice for heartier baked goods and rustic breads.
Gluten-Free
Oat Flour is gluten-free, making it an excellent choice for those with gluten sensitivities.
Unlike oat flour, whole wheat flour contains gluten. If you have gluten allergies, be sure to check labels for allergen information.
Storage and Alternatives
The shelf life of these flours is another practical consideration:
- Oat Flour: It typically stays fresh for about 2 months when stored properly.
- Whole Wheat Flour: You can expect a slightly longer shelf life of around 3 months, although it might vary due to its higher natural oil content compared to oat flour.
