Fructose malabsorption, formerly named dietary fructose intolerance (DFI), is a digestive disorder [1] in which absorption of fructose is impaired by deficient fructose carriers in the small intestine's enterocytes. This results in an increased concentration of fructose. Intolerance to fructose was first identified and reported in 1956. [2]
Fructose intolerance may refer to: Fructose malabsorption , a digestive disorder of the small intestine in which the fructose carrier in enterocytes is deficient Hereditary fructose intolerance , a hereditary condition caused by a deficiency of liver enzymes that metabolise fructose
Food intolerances can be classified according to their mechanism. Intolerance can result from the absence of specific chemicals or enzymes needed to digest a food substance, as in hereditary fructose intolerance. It may be a result of an abnormality in the body's ability to absorb nutrients, as occurs in fructose malabsorption.
Apples. The original source of sweetness for many of the early settlers in the United States, the sugar from an apple comes with a healthy dose of fiber.
The key identifying feature of HFI is the appearance of symptoms with the introduction of fructose to the diet. [ 5 ] [ 6 ] Affected individuals are asymptomatic and healthy, provided they do not ingest foods containing fructose or any of its common precursors, sucrose and sorbitol .

An elimination diet, also known as exclusion diet, is a diagnostic procedure used to identify foods that an individual cannot consume without adverse effects. [1] Adverse effects may be due to food allergy , food intolerance , other physiological mechanisms (such as metabolic or toxins), [ 2 ] or a combination of these.
Lactose intolerance is found in most adults, except for specific geographic populations, notably those of European descent. [20] Many who benefit from a low FODMAP diet need not restrict fructose or lactose. It is possible to identify these two conditions with hydrogen and methane breath testing, thus eliminating the necessity for dietary ...
