Fiber is a generic term for carbohydrate compounds that are not digested by human digestive enzymes and therefore transported undigested hang tags into the colon. Although fiber is not absorbed in the intestine has several important functions, including for bowel function. In the colon, the bacteria can ferment some of the fiber to form short fatty acids. These can be absorbed, and this way we can harness some of the energy from this macro-nutrient.
The definition of fiber has over varied little, and which compounds are included under the term may vary slightly according to who you ask. Fiber consists of indigestible polysaccharides and starch naturally falls outside this definition. Now we know, however, that also a part of starch escaping digestion in the small intestine. This is called resistant starch, hang tags and it has been debated whether resistant starch should be considered as fiber or not. Other indigestible carbohydrates, such as inulin, galactooligosaccharides (GOS) and fructo-oligosaccharides (FOS) has been discussed since the molecules are smaller than what has traditionally been considered fiber.
Fibers are carbohydrate polymers with at least ten monosaccharide units which do not hydrolyzed by digestive enzymes in the human small intestine and belong to the following hang tags categories. Edible carbohydrate polymers naturally found in the food we eat. Carbohydrate as the physical, chemical or enzymatic show is taken from foods, which are shown to have health beneficial effects demonstrated hang tags by adequate scientific evidence and approved by the competent authority. Synthetic carbohydrate polymers which have been shown to have health beneficial effects demonstrated by adequate scientific evidence and approved by the competent hang tags authority.
This definition does not include indigestible carbohydrates with less than 10 monosaccharides in the chain, as inulin and GOS / FOS. However, it is noted to be up to the national authorities to assess whether these should be included under the definition of fiber.
It's popular to divide fiber into soluble and insoluble fiber, but whether this categorization is useful, it may be questioned. Whether a fiber molecule hang tags is soluble in water outside the body is not a good predictor of the physiological function and there is no guarantee that the fiber dissolves when it is in the intestine. Already in 1998 proposed FAO / WHO that one should stop using these, yet it is still common to use these concepts. Features hang tags
Fiber has a number of physiological hang tags functions of the digestive tract, hang tags and affect the uptake of nutrients and general bowel function. Digestion of carbohydrates begins in the mouth by digestive enzymes in the saliva and mechanical crushing during chewing. Fiber-rich foods are more resistant to this degradation and digestion is delayed somewhat. In the stomach will fiber help ensure it stays longer before emptying into the small intestine. This contributes to the glycemic response of the cost is reduced. In the small intestine inhibits the fiber uptake of glucose by making carbohydrates less accessible to digestive enzymes. Different fiber types may influence this in different ways. Insoluble fiber from whole grains, for example protects the starch lies within, but have little hang tags protective effect in other carbohydrates in the intestine. Other more soluble fiber helps to bind intestinal contents together in a more viscous mass that is less accessible to digestive enzymes, which thus takes longer to digest food. Fiber can also bind to the ionized substances, such as minerals and heavy metals, and prevent the recording thereof. Also other organic hang tags substances can be bound to the fiber and thereby prevent absorption. There is little evidence that fiber has a negative effect on mineral metabolism in humans, but large amounts of phytate found in whole grain products and legumes bind to divalent minerals such as zinc, magnesium and calcium and inhibits the absorption of these. All fiber types helps to increase the weight on the stool, both by keeping the liquid hang tags and by increasing bacterial mass. Insoluble hang tags fibers such. whole grain contributes hang tags primarily by keeping the liquid, while fermentable fibers primarily helps to increase the amount of bacteria.
Fibres also have a variety of metabolic functions by influencing the uptake hang tags of nutrients hang tags and in that they can be fermented in the colon and give rise to short fatty acids. Fiber is good for blood sugar control. This is due to the effects of fiber have on the absorption of carbohydrates. There is also evidence that fiber affects the secretion of hormones that help regulate blood sugar. At the bottom of the intestine hang tags has endocrine cells that produce hormones in response to contact with
