Everything You Need to Know About Fiber

Healthy nutrition implies consumption of carbs, fats and proteins in right amounts as these are the substances human body transforms into energy. Metabolism speed depends on correctly chosen ratio of the energy sources. Compared to carbs, fiber does not boost metabolism or provide body with energy. Yet, it is required to ensure proper nutrition. Digestive ferments of stomach do not break fiber down, therefore nutritionists consider this component of nutrition as a ballast substance.

Ballast is doing good to the human body as undigested fiber is a source of healthy gut microflora. Microorganisms, which inhabit large intestine, where a fiber gets to, affect coarse vegetable fiber. They break fibers into fatty acids and transform them into amino acids and vitamins. Compared to refined food, dietary fibers of vegetable origin serve as the fillers and cleaners of intestine. They increase speed the digested products are delivered with from lower bowels and ensure its proper functioning.

What is Fiber?



Fiber is a dietary fiber, which is also called a ballast substance. However, nutritionists admit the important role of fibers in nutrition, they call it «a food for the gut microflora». It can be found in the vegetable food only such as rough fibers of leaves, skin and cover of grains and seeds. It is a polysaccharide in terms of its chemical content. Gut enzymes affect fiber turning it into glucose and enrich the cellular membranes.
