Why Are Oat Products So Popular?

Health Benefits Of Oat Flour And Oat Bran
Oats and oat products like oat flour vs oat bran are superfoods. They offer a variety of health benefits including digestion, heart health, blood sugar regulation, weight management, and cancer prevention!
Digestion
Oat products are great for the digestive system! They are high in fiber, which helps promote healthy digestion and bowel movements, preventing constipation.
Oat products include both soluble and insoluble fiber.
Soluble fiber helps to absorb water in the digestive tract and slow the digestion process, which helps with nutrient absorption (1). Insoluble fiber is needed to build bulk for our stool (1).
The type of soluble fiber is called beta-glucan, known to help reduce cholesterol levels.
Heart Health
Soluble fiber, found in the portfolio diet, can help to lower LDL cholesterol (the bad cholesterol) which may reduce the risk of heart disease.
Soluble fiber will bind cholesterol, causing it to be excreted in our stool rather than absorbed into the bloodstream (1).
This is important because a buildup of LDL cholesterol in the bloodstream can cause blockages in the arteries, which puts strain on the heart, putting you at a higher risk for heart disease.

Blood Sugar
Fiber also helps to control blood sugar levels (2).
Blood sugar refers to the amount of glucose that is found in your blood. When we eat carbohydrates, our bodies break them down into glucose, which is then used for energy.
However, having too much glucose in your blood can be harmful and is a condition called hyperglycemia (or high blood sugar), often seen in those living with diabetes.
Fiber is a type of carbohydrate that passes through our digestive tract without being broken down into glucose. Because of this, it does not raise blood sugar levels.
As mentioned before, fiber also helps to slow down digestion of sugar which can prevent spikes in blood sugar after eating.
Body Weight
Since fiber helps to slow digestion, it helps to keep you feeling full for longer after eating, meaning you will be less likely to overeat.
When combined with other healthy choices, such as exercising, eating more fiber can help maintain a healthy weight.
Cancer
It has been suggested that a diet with high fiber intake can help to lower the risk of breast cancer as well as colorectal cancer (2).
