FOOD PROPERTIES OF OAT BRAN
What is oat bran?
Oat bran is the product that becomes from refining the grain of oats. It contains mostly the husk of the grain, and also some fragments of the endosperm.
Bran corresponds to what would be the outer layers of grain and more specifically the pericarp, with its three sub-layers: exocarp, mesocarp and endocarp (rich in fiber and minerals), testa (rich in vitamins and enzymes) and the aleurone layer (rich in proteins and fats)
What parts of the grain does oat bran have?

Oat bran preserves some parts of the endosperm or grain, which is the part rich in carbohydrates.
Because of this composition, oat bran contains more fiber than oats in flakes or grain, and fewer carbohydrates.
In the refinement of the grains, the elimination of these layers supposes the deprivation of a whole series of fiber that is very important for health.
Antinutrients of oat bran
In the husk of cereals is also where you can find more phytates, some antinutrient substances.
They are called antinutrients because phytates are able to bind to minerals such as iron, zinc or calcium and prevent their absorption (mineral thieves). For this reason, you should not abuse the consumption of these fibers and should only be consumed in those cases where it is not possible to provide this fiber through the diet.
CURATIVE BENEFITS OF OAT BRAN
Although oat bran contains other components, the main curative properties of this supplement, like in wheat bran, come from its non soluble fiber wealth.
Between the main properties of oat bran we will mention the following:

Oat bran supplements are used in weight loss diets because of the property of soluble fiber (beta-glucans) to hydrate and provide a sensation of early satiety.
It also has proven properties to reduce cholesterol, being doubly beneficial in those cases where there is obesity and high levels of these fats are present in the blood.
Oatmeal is also suitable from a nutritional point, because it has a balanced composition, with fewer carbohydrates, more protein and more fiber than other cereals.

Oat bran is very useful to control constipation
A spoonful of oat bran
The fiber contained in oat bran increases intestinal peristalsis and softens the stool so that they are expelled to the outside more easily and frequently, preventing constipation, a condition that affects many adults in Western society because of removing the bran in cereals and grains.
By comparative studies, it has been seen that cultures that eat foods high in fiber have a much higher number of stools. In India, the average of the stool is calculated between 300 and 500 grams per day, with a residence time in the gut of about 30 to 35 hours. In the western world people keep their feces for 3 days for adults and about 15 days old. The average weight of these is estimated only about 100 g.
