Dietary fiber, insoluble fiber, high fiber diet food and a good source of fiber


What is dietary fiber, insoluble fiber, high fiber diet food, and a good source of fiber? How good for our digestive system. How much take daily fiber meal.


Fiber is an uncommon meal part. They are usually not digested in our abdomen and small gut, which can counsel that they’re comparatively ineffective. Their destiny is situated decrease, within the colon, the place they contribute to the regulation of transit, but also exert essential results for well being. Let’s uncover this hidden face of fibers!

Fiber just isn’t digested by enzymes within the digestive tract
They promote intestinal transit
They function meals for colon microorganism: the microbiota
The microbiota is an organ that impacts our well being
Some fibers are soluble, others insoluble
Vary your sources of fiber!


Dietary fiber is a really heterogeneous household of gear. However, they’ve one factor in widespread: due to their chemical construction, they’re neither digested nor absorbed within the small gut. This peculiarity is exclusive: proteins, carbohydrates, and lipids are absorbed within the small gut and supply vitality. For fiber, digestion and vitality consumption happens to decrease within the digestive tract: on the colon.
For a very long time, it was thought that their function was restricted to that of ballast, or broom of the massive gut, in brief, that of a natural waste that needed to be eradicated naturally. In apply, they’ve results that go far past regulating transit. The goal of those results relies on their nature.

In apply, there are two foremost teams:

fibers naturally current in meals, which break down into two subfamilies:
Insoluble fibers: cellulose, lignin, sure hemicelluloses… current in cereal merchandise, particularly “complete”.
Soluble fibers: sure hemicelluloses, glucans, pectins, gums, carrageenans, resistant starches, inulin… current particularly in vegetables and fruit, legumes, algae, potatoes, and cereals.
fibers remoted and purified from uncooked supplies and scientifically acknowledged for his or her helpful results (oligofructose, and so forth.) for well being.
Other non-digestible compounds, akin to phenolic compounds, waxes, saponins, phytates, cutin, and phytosterols are additionally related to their definition, which evolves recurrently.


Why is it essential to grasp the existence of all kinds of dietary fibers? 

Simply as a result of learning from all their results, it’s actually essential to eat sufficiently, but in addition to fluctuating the sources day-after-day!
Some of them (akin to pectins, gums, oligosaccharides, and resistant starches) might be fermented by the microorganism within the intestinal microbiota and generate physiological results that may impression the entire physique! Others, akin to cellulose and lignin, are poorly fermented, assist regulate intestinal transit, and improve the number of stools.


Associated with adequate hydration (the extra we eat, the extra it’s essential to drink), they exert a regulating impact on intestinal transit. The period “regulator” signifies that they cut back the slowing down of transit (constipation) and management its acceleration 
 This impact works by way of a rise in intestinal motility (the gut is a muscle that contracts) and by way of hydration which causes a mass impact answerable for a rise in stool quantity. By decreasing the pace of digestion, additionally, they optimize the sensation of fullness and assist to manage urge for food higher.
But that is simply the hidden facet of the iceberg! By serving as a substrate for the intestinal microbiota, which is a central protection and management organism, fibers take part within the prevention of many ailments, akin to cardiovascular ailments, weight problems, sort 2 diabetes, sure cancers. and even the chance of infections and inflammatory pathologies, by modulating the exercise of the immune system.


To make sure ample intestinal features, in Europe, EFSA recommends consumption of two g of dietary fiber per MJ of caloric consumption and day in kids from the age of 1 yr (EFSA, 2010). In adults, the full quantity to devour should be equal to or larger than 25 g per day for the correct bowel perform. For the prevention of heart problems or sort 2 diabetes, and consumption of 30 g per day is beneficial. This suggestion additionally applies within the context of weight problems, the prevention of sure cancers.

They are discovered primarily within the plant kingdom. The finest sources are dried fruits and legumes (soy, lentil, chickpeas, dry beans, and so forth.), in addition to entire grain merchandise (rice, bread, pasta, flour, oats, and so forth.). Vegetables and fruits are additionally sources or wealthy in fiber, relying on their nature.

The fibers of vegetables and fruit are for a few thirds of the soluble fibers. Pulses have about 1/Four of soluble fiber.


The lack of dietary fiber within the weight loss program is detrimental to the standard of intestinal transit. It is, without a doubt, one of the main causes of constipation.
