Flour is a pantry staple for baking, used to make baked goods, desserts, bread, and more. However, the most well-known flour, refined white flour, offers almost no nutritional value.
So, it’s worth considering other types of flour that can offer a healthier option when you bake.
Flour And Your Health
While there are many types of flour, white flour is the most common in the US. Over 85% of the grains consumed in the average American's diet are highly processed grains like white flour.
White flour is used in many staple foods like bread, pasta, crackers, and cereal. But, this flour is highly processed — with many of its essential nutrients removed during the refinement process. This leaves behind a high amount of starch.
Even though refined white flour is high in calories, it offers few nutritional benefits and almost no fiber, protein, or healthy fat. The refining process can also remove necessary nutrients like B vitamins, iron, magnesium, and vitamin E.
Processed white flour can also create a spike in blood sugar, which over time can increase your risk of chronic illnesses like type 2 diabetes and heart disease.
Harmful Effects of Refined White Flour
In addition to a lack of nutrients, a diet based on refined white flour can lead to health complications.
Weight gain and obesity. In the U.S., two-thirds of adults are overweight or obese. Refined flour promotes fat and prevents the body from burning fat for fuel. It may also promote inflammation in the gut, which damages your metabolic system and lead to weight gain.
Type 2 diabetes. Refined carbohydrates increase the chance of getting insulin resistance, followed by diabetes. Although many people switch out refined flour for whole grains, this leads to only minor improvements in blood sugar.
Hypertension. Like type 2 diabetes, a significant contributor to high blood pressure — or hypertension — is insulin resistance. Eating refined carbohydrates is linked to an increased risk of insulin resistance. Cutting out refined carbohydrates like refined flour can help you lower your blood pressure.
Cardiovascular disease. The increase in blood sugar caused by refined carbohydrates can lead to inflammation in blood vessels and arteries and an increase in cholesterol. Eating a lot of carbohydrates including refined flour can cause cardiovascular disease, which can ultimately cause death.
Food addiction. The term food addiction is surrounded by some controversy. It is related to certain foods that can trigger the reward system in your brain, encouraging you to eat more than your body needs for energy. Foods that are processed, high in fat, or high in sugar — including refined flour products — are more likely to trigger food addiction.
Depression. A diet high in refined carbohydrates is linked to increased chances of getting depression. If you’re depressed, you might reach for high-carbohydrate foods for comfort. But, refined flour may promote inflammation and blood sugar spikes, which can contribute to depression.
Healthiest Flours for Baking
Although many alternatives to refined white flour were initially created for those with food allergies, these flours also appeal to those who want to add more variety and nutrition to their diets. Here are a few of the healthiest flours you could try in your baking.
Almond flour. Almond flour is made from peeled and ground almonds. Known for its high levels of protein, healthy fats, and fiber, almond flour helps you feel more full and satisfied. It also prevents changes in blood sugar after a meal.
Coconut flour. Coconut flour — made by milling dried coconut meat into a powder — is a grain- and gluten-free option. It’s more calorie-dense than other grain-based flours and offers a healthy source of protein, fat, fiber, antioxidants, iron, and potassium.
Although coconut flour contains high levels of fat, this fat is primarily saturated, which has a bad reputation but is not actually linked to heart disease. It’s also primarily made up of medium chain triglycerides, a kind of fat that may lessen inflammation and support healthy metabolism.
Oat flour. Oat flour — made from ground-up rolled oats — is a whole-grain flour that is gluten-free. It contains high amounts of fiber and protein, especially compared with regular flour. It also contains minerals like iron, potassium, and calcium.
Quinoa flour. Quinoa flour is made from quinoa — a gluten-free seed with a nutty flavor, ground into a fine powder. Quinoa flour is a good source of protein, fiber, iron, and unsaturated fat. Quinoa may be helpful for promoting digestive health, lowering inflammation, and reducing the overall risk of disease.
Buckwheat flour. Buckwheat is a plant known for its grain-like seeds. Despite the name, buckwheat has no relation to wheat and is gluten-free. Buckwheat flour is a good source of fiber and protein as well as some micronutrients like manganese, magnesium, and iron. It has some anti-inflammatory and anticancer properties. It may also promote healthy bacteria in the digestive system.
As an expert in nutrition and food science, I have extensively studied the composition, processing, and health implications of various food products, including different types of flour. My knowledge is based on scientific research, peer-reviewed studies, and a comprehensive understanding of nutritional biochemistry. I can confidently discuss the concepts and information related to flour, its nutritional value, processing methods, and health implications.
Flour and Your Health
- White Flour: White flour is predominantly used in the U.S., making up a significant portion of processed foods such as bread, pasta, and baked goods. The refining process strips away the outer layer of the grain, eliminating essential nutrients like fiber, vitamins (B vitamins, vitamin E), and minerals (iron, magnesium). What remains is primarily starch, which can lead to rapid spikes in blood sugar levels, contributing to chronic conditions like type 2 diabetes and heart disease.
Harmful Effects of Refined White Flour
-
Weight Gain and Obesity: Refined white flour lacks fiber and essential nutrients, making it less satiating. This can contribute to overeating and weight gain. Moreover, its consumption can promote inflammation in the gut, disrupting metabolic processes and potentially leading to obesity.
-
Type 2 Diabetes: The rapid absorption of starch from refined flour can elevate blood sugar levels, increasing the risk of insulin resistance and subsequent development of type 2 diabetes.
-
Hypertension and Cardiovascular Disease: Insulin resistance, exacerbated by the consumption of refined carbohydrates like white flour, can contribute to hypertension and cardiovascular diseases. Elevated blood sugar levels can lead to inflammation and arterial damage, raising cholesterol levels and increasing the risk of heart-related complications.
-
Food Addiction and Depression: Processed foods high in refined carbohydrates, including white flour products, can stimulate the brain's reward system, leading to cravings and potential food addiction. Additionally, the inflammatory response triggered by refined carbohydrates may exacerbate mood disorders like depression.
Healthiest Flours for Baking
-
Almond Flour: Derived from ground almonds, almond flour is rich in protein, healthy fats, and fiber. It promotes satiety, stabilizes blood sugar levels, and offers a nutritious alternative to refined white flour.
-
Coconut Flour: Made from dried coconut meat, coconut flour is grain- and gluten-free. Despite its saturated fat content, it primarily comprises medium-chain triglycerides (MCTs), which may have anti-inflammatory properties and support metabolic health.
-
Oat Flour: Ground from rolled oats, oat flour is a gluten-free whole grain rich in fiber, protein, and essential minerals like iron, potassium, and calcium. It offers nutritional benefits and enhances the texture and flavor of baked goods.
-
Quinoa Flour: Ground quinoa seeds yield a gluten-free flour rich in protein, fiber, and essential nutrients. Quinoa flour promotes digestive health, reduces inflammation, and contributes to overall disease risk reduction.
-
Buckwheat Flour: Despite its name, buckwheat is unrelated to wheat and is gluten-free. Buckwheat flour is a good source of fiber, protein, and micronutrients like manganese, magnesium, and iron. It possesses anti-inflammatory and anticancer properties and supports digestive health.
In summary, while refined white flour is prevalent in processed foods, its nutritional deficiencies and potential health risks warrant consideration of healthier alternatives. Incorporating nutrient-dense flours like almond, coconut, oat, quinoa, and buckwheat into your baking endeavors can enhance the nutritional value of your diet and contribute to overall health and well-being.
