What Is Dietary Fiber?

Every other diet specialist will talk about fiber, fiber diet, and a whole lot of explanations that leave you wondering how complicated the issue of nutrition really is. But the whole concept of dietary fiber is not really rocket science, if there are no doctors, that is. It is a simple thing that anyone would understand. Anyway, what is a dietary diet? Why is it important? Does it entail anything to absorb enough fiber?

Dietary fiber, sometimes popular as roughage, refers to that part of our diet, mainly plant food, that is not digested by our systems. This part usually consists of two parts, both which are not digested but are different in their own ways. These two are the soluble and the insoluble parts.

The soluble part is usually readily fermented and transformed to various physiologically active products that include sweat and urine, and, sometimes, gases. These are sometimes called prebyotic sections of the diet, or viscous, referring to their viscosity.

The other part; the insoluble part, is usually metabolically inert, meaning it cannot possibly be fermented into any byproducts, but is probably the most useful part in the sense with which it contributes to the digestion process. This food material remains solid, and absorbs the water in the large intestines as it moves down to be excreted through the gut in the same solid form.

There are so many good effects associated with fibers. Doctors recommend that you consume 25 to 30 grams of fiber daily. First and foremost, soluble fibers dissolve in water to form a gel like substance. This substance is necessary in reducing dietary cholesterol in the blood. The content is also helpful in increasing insulin resistance hence balancing the sugar level in the blood. The other insoluble type of fiber is useful in adding weight to the stool and protecting the colon system.

Fiber rich foods are very vital in our everyday of living because ignoring them puts our lives at risk of contracting serious and severe diseases. I think nobody likes and would want to suffer from heart disease, kidney stones, diabetes, and gallstones. Whenever we include vegetables, fruits and whole grains in our diet, we only try to protect our body against such diseases. Our immune system will also grow stronger and stronger in the process.

The chemical components of the fiber diet are non-starch polysaccharides mainly cellulose which the body system is not able to digest normally and transform them into the various products and byproducts which are usable by the body metabolism. Their presence in the digestive system is of importance as in not only ensures absorption of excess water in the large intestines, but also promotes easier digestion and absorption of foods, whole still enabling ease of excretion.

Taking fiber rich is not that expensive. These kinds of foods are just like meat and pork and their costs are reasonable. You are only required to add the supplements of fiber into your food whenever you take a meal. So it isn’t that difficult to understand really, is it? Surely it shouldn’t be.
