Oat bran husks are packed with fiber and nutrients and are becoming a popular health food staple.

What is Oat Bran?

Oat bran is made from the outer husks of oat grain cereal (Avena Sativa), which is primarily grown in Europe and America. Usually sold in a meal-like consistency, oat bran is high in soluble fiber and rich in a range of vitamins, antioxidants, and minerals. This type of bran was once reserved for feeding cattle and livestock, but in recent years, the nutritional value of this part of the grain has lifted it into popularity for healthy eaters. Oat bran contains more magnesium, potassium, phosphorus, protein, and fiber, as well as fewer fats per 100 grams, than whole or rolled oats. An article by JW Anderson, published by the American Journal of Clinical Nutrition, argues that oat-derived bran and other concentrated forms of dietary fiber can be beneficial for dozens of different health conditions, including various forms of cancer and heart disease.

Health Benefits of Oat Bran

Oat bran has many amazing benefits including the lowering of cholesterol levels, defending against diabetes, promoting weight loss, and improving neurological health among others. Let us take a detailed look at them below.

Defends Against Diabetes

Those diagnosed with type-2 diabetes have difficulty regulating their blood sugar levels. The beta-glucan soluble fiber present in oat bran helps the body better control blood sugar, slowing the absorption of sugar into the bloodstream and improving sensitivity to insulin, as per a study published in the journal NMCD in 2005. It also states that regular consumption of oat bran helped to reduce the postprandial glucose response by the body, unlike many other forms of cereal, such as wheat flour.

Prevents Heart Disease

The key soluble fiber in this type of cereal bran is beta-glucan. This fiber binds with cholesterol-containing bile and removes it from the body. High levels of cholesterol are directly linked with heart disease. By helping avoid the build-up of plaque in the arteries, oat bran does a great deal to keep blood pressure regulated and the cardiovascular system healthy. Several studies have demonstrated that oat bran is effective in helping to lower our overall cholesterol levels.

Aids Weight Loss

A high-fiber diet is recommended for weight loss, as it absorbs water and creates a feeling of fullness, which successfully postpones hunger. Overall, this means that you consume fewer calories. Bran is an excellent source of fiber. In a study published in the Journal of Nutrition, conducted by Dr. Joanne Slavin, the addition of fiber to weight-loss diet was a clear complement to the successful reduction in body weight.

Prevents Constipation

Fiber is an ally to the digestive system, as it helps to promote the regular and healthy consistency of stool. Be sure to drink plenty of water to help the body process the fiber appropriately.

Aids Neurological Health

Oat bran is also a very good source of protein. In addition to giving the body strength and energy, protein is broken down into amino acids, some of which play a vital role in the healthy functioning of the brain and thyroid.

Aids Skin Care

Oats are often used in skincare products due to their high mineral content and soothing properties. When applied topically, oat bran can be used holistically in the face or body scrubs and may help ease the symptoms of eczema, dry skin, and rashes.

Good Gluten-Free Option

Studies have shown that most celiac patients are able to digest oats, making it a good alternative protein and carbohydrate source. That being said, a review published in the World Journal of Gastroenterology by Dr. Isabel Comino et al., suggests that the type of oats used by celiac patients will determine whether they can safely consume the bran. In other words, not all oats are created equal.

Protects Against Colorectal Cancer

Consumption of whole-grain foods such as oat bran may protect against colorectal cancer and is beneficial for inflammatory bowel disease and coeliac disease as per a study published in The British Journal of Nutrition. Colorectal cancer.

Another study by The American Journal of Medicine has demonstrated a reduced risk of colon cancer when a group of people with diets high in total fat switched to a diet high in total fiber and certain whole-grain food items. 

Oat bran Vs Oatmeal

Oatmeal and Oat bran differ particularly based on their degree of processing and also include variations in their nutrient content, too.

What Is Oatmeal?

All oats start at “groats”, the whole unbroken grain granule. They then transform into steel-cut and rolled varieties depending on their degree of processing.

• Rolled oats: After harvesting and hulling, oats are mashed or”rolled down” to the well-known flattened flake. “Old-fashioned” oats are a type of rolled oats that offer the most texture. Another type is instant oats which are highly preferred and also are a kind of rolled oats. They cook quickly and tend to make a puffier, mushier product. 

• Steel-cut oats: Instead of being rolled, steel-cut oats are sliced by steel blades. They are roughly grounded and less refined than other oats. This leads to a chewier texture with longer cooking time. 

What are Oat bran?

Unlike other oatmeal varieties, oat bran is not considered a whole grain. Suggestively names, oat bran is produced from the outer grain including its multiple layers such as mesocarp, exocarp, and endocarp. The whole grain contains all three layers, proposing that oat bran is not considered a whole grain.

Although the germ and endosperm are absent, the bran still provides fiber, vitamins B, and antioxidants.

Oatmeal and Oat bran Nutrition

The nutrient profiles of each differ distinctively. However, oat bran is lesser in calories and offers more protein and fiber.

Additionally, speaking about micronutrients, both are excellent sources of vitamins and minerals. Oat bran, however, offers more fiber and minerals like magnesium, potassium, and phosphorus. Alternatively, rolled oats are an excellent source of zinc.

Ultimately, differences are marginal in both, yet these offer rich nutrients.

How to Include Oat Bran in your Daily Diet?

Oat bran is easily incorporated into your daily diet as a breakfast cereal. You can make hot porridge or leave the oats to soak in water overnight to make a healthy, cold version of porridge. Some people also sprinkle ground oat bran onto stews, soups, or other kinds of breakfast cereal. Alternatively, use oat bran to make granola and granola bars, pancakes, cookies, bran muffins or bread. You can experiment with using powdered oat bran as a healthy substitute for flour. You may even like to make your own face mask or body scrubs at home using soaked oat bran as a base ingredient; try combining it with honey, yogurt, and a little oil.

Side Effects

Eating oat bran in large amounts can cause gas and bloat. Monitor your intake to avoid these gastrointestinal symptoms. Using oat-related skin products may cause a breakout reaction in a small minority of people. Avoid eating oat bran if you have any pre-existing digestive issues relating to the stomach, intestines or esophagus. There is a risk of oats blocking the intestines if the digestive process is significantly slowed down. Before making any major changes to your diet, it is best to speak with your doctor or a nutritionist.
