		Fructose malabsorption or Dietary Fructose Intolerance is a dietary disability of the small intestine in which the fructose carrier in enterocytes is deficient.
		Fructose Malabsorption is not to be confused with Hereditary Fructose Intolerance (HFI), a hereditary condition in which the liver enzymes that break up fructose are deficient.
		In the large intestine the unabsorbed fructose osmotically reduces the absorption of water and is metabolized by normal colonic bacteria to short chain fatty acids and the gases hydrogen, carbon dioxide and methane.

	fructose - Encyclopedia.com
		fructose, levulose, or fruit sugar, simple sugar found in honey and in the fruit and other parts of plants.
		Glucose and fructose are formed in equal amounts when sucrose is hydrolyzed by the enzyme invertase or by heating with dilute acid; the resulting equimolar mixture of fructose and glucose, called invert sugar, is the major component of honey.
		Fructose reacts with Fehling's solution and can be differentiated from glucose by its reaction with lime water to form a water-insoluble precipitate, calcium fructosate.

	"Understanding Fructose Malabsorption."
		Fructose malabsorption is the inability to digest fructose, a common sugar found in many prepared foods and soft drinks.
		Fructose malabsorption occurs due to the body's lack of fructase, an enzyme normally produced by the small intestine.
		In a patient suffering from fructose malabsorption the hydrogen is absorbed from the intestines, carried through the blood stream to the lungs and exhaled.

	Purple Puzzle Place: Fructose Malabsorption
		Fructose absorption (in the non-hereditary form of intolerance) is affected by glucose levels, not just fructose levels alone.
		With hereditary fructose intolerance she would have to pretty much completely avoid all fructose and sucrose of any kind, which would mean essentially all fruits and vegetables, legumes and whole grains--as one sufferer put it, "pretty much anything that grows out of the ground".
		Baby E's fructose malabsorption seems to be fairly severe (4 flberries?!), but it does (at least in my internet-educated opinion) seem to be malabsorption rather than the more serious form.

	foodreactions.org:: Fructose Intolerance
		Hereditary Fructose Intolerance (HFI) is a rare genetic disorder of fructose metabolism due to a deficiency of the enzyme, aldolase B that finishes the conversion of partially converted fructose (fructose-1-phosphate) into glucose.
		Hereditary Fructose Intolerance (HFI) should not be confused with Fructose Malabsorption.
		In HFI fructose is not properly metabolised due to a deficiency of the enzyme, aldolase B. Normally, once fructose is absorbed it is transformed into fructose-1-phosphate by an enzyme called fructose-1-phosphate aldolase.

	Food-Info.net : Fructose intolerance malabsorption and HFI
		Fructose intolerance (also known as fructose malabsorption) and HFI (Hereditary Fructose Intolerance) are two very distinct metabolic disorders, in which fructose is not well tolerated.
		The fructose is normally absorbed by the body from the small intestine, but in the liver the body misses the enzyme fructose 1-phosphate aldolase (Enzyme Classification Code EC 2.1.2.13), which is a key enzyme in the further metabolism of fructose.
		In the large intestine fructose is rapidly fermented by the intestinal bacteria (intestinal microflora) to acids and gases, predominantly hydrogen and carbon dioxide.

		In particular, fructose is a potent reducing sugar that promotes the formation of toxic advanced glycation end-products, which appear to play a role in the aging process; in the pathogenesis of the vascular, renal, and ocular complications of diabetes; and in the development of atherosclerosis.
		In contrast, the rise in serum fructose concentration that occurs after ingestion of a bolus of fructose or sucrose is probably due to an inability of the intestinal and hepatic enzymes to metabolize the load completely.
		Fructose unfavorably affects each of the three major factors that are thought to contribute to the pathogenesis of diabetic end-organ damage: glycosylation of tissue proteins, intracellular accumulation of sorbitol, and oxidative stress.

	Fructose Intolerance & Fructose Malabsorption \| Foodintol.com
		Sugar malabsorption is the inability (in some people) of the small intestine to break down sugars like fructose (most common), lactose or sorbitol into smaller molecular fragments for digestion.
		In these people, because fructose (or lactose or sorbitol) is not absorbed by the intestine the condition is known as malabsorption, or an inability to be absorbed.
		Fructose malabsorption therefore is not only associated with gastro-intestinal distress but also the inability to absorb all kinds of nutrients which can lead to serious diseases like anaemia and osteoporosis.

	Fructose and high fructose corn syrup: by Ray Sahelian, M.D. benefit and harm
		Ray Sahelian, M.D. Fructose is found widely in the diet as a free monosaccharide hexose, as the disaccharide, sucrose and in a polymerized form (fructans) as a component of plant oligosaccharides.
		Because fructose is considerably sweeter than sucrose, it is used to enhance the flavor, color stability, and freezing point depression of many foods and beverages.
		It is proposed that confusion over the clinical relevance of fructose malabsorption may be reduced by regarding it not as an abnormality but as a physiological process offering an opportunity to improve functional gastrointestinal symptoms by dietary change.

	FAQ: HFI Detailed
		Aldolase B is the major aldolase isozyme in the liver and functions in both fructose metabolism, using fructose 1-phosphate as a substrate, and in gluconeogenesis, producing fructose 1,6-bisphosphate from the two triose phosphates, glyceraldehyde-3-phosphate and dihydroxyacetone phosphate.
		The treatment for HFI is the exclusion of fructose, sucrose, and sorbitol (less than 40 mg/kg per day) from the diet (3) and results in complete alleviation of most symptoms and a normal life span (1).

		Because the concentration of the sugars (glucose, fructose and sucrose) in fruit juice is influenced by storage and the particular types of fruit (for example, type of apple) used, each juice will differ in concentration of the different sugars.

		HFI is a rare autosomal recessive disorder of fructose metabolism, due to a deficiency of fructose-1-phosphate aldolase activity.
