If your household is like most, you’ll probably find the usual types of flour sitting in your kitchen for cooking and baking. And by usual, we mean self-raising flour, plain flour, and perhaps one or two other types. There is a plethora of flours to be found in supermarkets and health food stores, but how do they compare both nutritionally and in a practical sense?
Our garden variety white or plain flour is made from ground wheat. The wheat grain itself consists of three parts – the bran (outer layer), endosperm (mid-section) and germ (nutrient-rich inner section). The outer bran layer is rich in fibre and minerals, and contains some good fats, antioxidants, thiamine, protein and phosphorus but is completely removed in the making of white flour. The germ is the innermost part of the grain and an excellent source of B vitamins, Vitamin E, healthy fats, minerals and protein. However the milling process removes some of the germ, so that plain flour is made mostly of the starchy endosperm. Thus, plain white flour tends to be low in fibre and fat and high in carbohydrate followed by a medium protein content (also known as gluten). It is the gluten content that causes bread and baked goods to have a light, soft and spongy quality. Exhibit A would be a soft, fluffy bread bun at a Bunnings weekend sausage sizzle.
Due to the removal of fibre, vitamins, minerals and good fats to make white flour, foods made with large quantities of white flour (such as white bread) are quickly digested, having a fast action on increasing blood sugar levels and having a short-lasting effect on satiety. This can make it difficult to keep our weight in check because we don’t feel satisfied for too long. We miss out on dietary fibre beneficial to bowel health (including preventing constipation) and can’t feed the “good” gut bacteria which when given fibre, is likely to result in several health benefits. It is well known that a diet high in whole grains is associated with lower risk of bowel cancer, Type 2 Diabetes, heart attack, stroke and obesity.
However, white flour is not to be avoided at all costs – it isn’t all bad and can be mixed with other types of flours or ingredients to increase the nutritional profile of baked foods. For example, adding other types of flour containing more fibre, or adding slithered nuts, seeds, grains and fruit will yield a more nutritious product. Furthermore, it is important to know that Australian millers are required to add folic acid (a form of B Vitamin folate) to wheat flour for bread making purposes (except for organic wheat flour). Folic acid is essential for DNA synthesis and healthy development of babies in early pregnancy, so the Australian government has made folic acid fortification mandatory since September 2009. Other types of packaged flour such as rye, rice and corn flours are not required to contain folic acid.
So it makes sense that a flour (or a combination of mixed flours) that is lower in carbohydrate, higher in protein and fibre, and containing good fats would be a more nutritious choice for cooking and baking. Here are some potential flours to try:
Not all flours are created equal (unless you create your own concoction), but ideally those with a higher fibre content, vitamins, minerals, protein and lower quantity of carbohydrate are the most nutritious choices. Mind you, the occasional soft, fluffy piece of cake or bread is fine as an occasional treat!
