The truth about High Fiber Foods

    What are the Fibers?

    Normally, once the carbohydrates are assimilated, they are turned into sugar molecules. But there is one type of carbohydrate that does not obey this rule. Fibers are the only type of carbohydrates, which, instead of becoming sugar molecules, remain undigested. Doing so, fibers travel across the body, to regulate the usage of the body’s sugars, therefore helping in the process of keeping the hunger down and maintaining the normal parameters of the blood.

    Fibers are divided into two categories: soluble fibers and insoluble fibers. Both categories are equally healthy.

    Soluble fibers are those which are dissolved in water. The purpose of this type of fiber is to aid in lowering glucose and blood cholesterol levels. The soluble fibers are usually found in foods, such as oatmeal, nuts, beans, apples, and blueberries.

    Insoluble fibers have a different purpose than soluble fibers. As these fibers do not dissolve in water, they are a great help for the digestive system. They promote regularity and prevent constipation. The insoluble fibers can be found in foods like wheat, whole wheat bread, whole grain couscous brown rice, tomatoes, carrots, and cucumbers.

    Both adults and children are recommended to consume at least 20 grams of fiber per day. Even if the fibers can be taken from fruits, vegetables, whole grains, or beans, studies show that average Americans are consuming only 15 grams of fiber per day. Consuming between 20-30 grams of fiber per day is considered very healthy, as it has a role: 

    • To reduce cholesterol, as the existence of fiber within the digestive tract can reduce significantly the body’s cholesterol absorption;
    • To maintain a healthy weight, eating high-fiber foods, for example, certain fruits and vegetables could signify a low-calorie intake. Moreover, these foods could help you postpone the feeling of hunger;
    • To help digestion, eating foods high in fiber could help you prevent constipation and other digestive problems. In other words, fiber stimulates digestion;
    • To control the blood sugar levels, as it takes some time for the body to break down the high fiber foods. This aspect of consuming fibers could be significant if you are suffering from diabetes;
    • To reduce the risk of gastrointestinal cancer, getting enough fiber daily could prevent several types of cancer, including colon cancer. Some types of fibers have properties that are very similar to antioxidants.
