fructans การใช้

• The role that fructans play in fructose malabsorption is still under investigation.
• Fructans are another source of prebiotic soluble dietary fibers.
• Due to the body's limited ability to process fructans, inulin has minimal increasing impact on blood sugar.
• These short-chain carbohydrates ( lactose, fructose and sorbitol, fructans and GOS ) behave similarly in the intestine.
• Restricting dietary intake of free fructose and / or fructans may provide symptom relief in a high proportion of patients with functional gut disorders.
• As it is the case with similar substances, such as fructans or inulin, sinistrin acts as an energy storage molecule in plants.
• The diet of the prehistoric hunter-forager in the Chihuahuan Desert has been estimated to include 135 g per day of inulin-type fructans.
• However, some fructose malabsorbers do not have difficulty with fructans from wheat products while they may have problems with foods that contain excess free fructose.
• After harvesting, the " pi馻s " are transported to ovens where they are slowly baked to break down their complex fructans into simple fructoses.
• A third type of fructans, the graminan-type, contains both ?-2, 1-linkages and ?-2, 6-linkages.
• Chemically defined as oligosaccharides occurring naturally in most plants, inulins have nutritional value as carbohydrates, or more specifically as fructans, a polymer of the natural plant sugar, fructose.
• "' Inulins "'are a group of naturally occurring polysaccharides produced by many types of plants, The inulins belong to a class of dietary fibers known as fructans.
• Diallyl disulfide found in the fructans containing garlic has been shown to reduce chemical toxicity and carcinogenesis in rodents, and shows synergestic benefits with butyrate when it comes to inhibiting the growth of human cancer tumor cells in the colon.
• "' Levans "'are a group of fructans; polymers of fructose forming a non-structural carbohydrate, which in the case of levans can themselves link together to form super-molecules comprising even hundreds of thousands.
• However, it is recommended that fructan intake for fructose malabsorbers should be kept to less than 0.5 grams / serving, and supplements with " inulin " and " fructooligosaccharide " ( FOS ), both fructans, should be avoided.
• Other examples of fermentable fiber sources ( from plant foods or biotechnology ) used in functional foods and supplements include resistant starch, inulin, fructans, fructooligosaccharides ( FOS ), and oligo-or polysaccharides, and resistant dextrins, which may be partially or fully fermented.
• It is still unknown whether the precise cause of their great success was the development of the highly specialised capitulum, their ability to store energy as fructans ( mainly inulin ), which is an advantage in relatively dry zones, or some combination of these and possibly other factors.
• Fructooligosaccharides ( fructans ) such as inulin, occurring in relatively large amounts in a number of foods such as chicory, garlic, onion, leek, artichoke, and asparagus, have a colon, such as bifidobacteria and lactobacilli, while inhibiting harmful ones, such as clostridia, fusobacteria, and bacteroides.
• Though the touted health benefits may exist, sufferers of fructose malabsorption will likely find no difference between these new breads and traditionally prepared breads in alleviating their symptoms because inulin is a fructan, and, again, consumption of fructans should be reduced dramatically in those with fructose malabsorption in an effort to appease symptoms.
• Gluten is likely responsible for the appearance of symptoms, but it has been suggested than in a subgroup of patients with NCGS and symptoms like IBS, other components of wheat and related grains ( oligosaccharides like fructans ), or other plant proteins contained in glutencontaining cereals ( agglutinins, lectins, and ATIs ) may play a role in the development of gastrointestinal symptoms.
