Fructose (Overview)

Fructose, or fruit sugar, is a simple monosaccharide found in many plants (fruits, vegetables, sugar cane and honey). Fructose is absorbed directly into the bloodstream during digestion. Since 1970 high fructose corn syrup has been increasingly used in the food industry. Excess fructose consumption has been linked to Insulin resistance, obesity, metabolic syndrome and lipid abnormalities.

By chance, 50% would be carriers and 25% would have no gene. However, in reality, every kid could be effected since conception could produce any combination. ...Read more

Symptoms of fructose malabsorption?

Symptoms of fructose malabsorption?

Gas, bloat, diarrhea: Fructose is a sugar that can be malabsorbed, just like lactose (milk sugar); bacteria in the gut will ferment the undigested sugar; fermentation products cause gas, bloat, cramps, diarrhea-depending on the "dose" of fructose. Fructose is found in fruits, e.g. Pears, apples. High fructose corn syrup is not high fructose, but is compared to cs (all glucose). High fruct cs is similar to sucrose. ...Read more

Fructose intolerance: Describes 2 possible conditions: hereditary fructose intolerance, a rare genetic disorder, is lack of an enzyme that breaks down fructose; it is serious and can lead to liver and kidney damage.

Symptoms/test.: This has symptoms like bloating, diarrhea and/or constipation, flatulence, and stomach pain. This has a diagnostic test called a hydrogen breath test and is the current test used for a clinical diagnosis. Fructose is given and, if not absorbes, is metabolized by bacteria that gives off hydrogen and methane. This is detected and anything higher than 12-15ppm is positive, typically 20ppm. ...Read more

How many people die from "hereditary fructose intolerance" per year?

Few: This is easily managed once the diagnosis is made, and a decent pediatrician would spot it by the child becoming sick when fructose is introduced to the diet. In a death (and these are very rare), the pathologist would recognize a metabolic problem and perhaps be able to make the call after the fact; some may be missed so no one can tell you exactly. ...Read more

Yes: Some forms of the disorder may not manifest until adulthood. "Froesch et al. (1963) described 2 adults, aged 33 and 39 years, with fructose intolerance. In addition to the aversion to fructose-containing foods, both had a remarkable absence of dental caries. Swales and Smith (1966) described an affected 21-year-old man, and Kohlin and Melin (1968) reported adult cases." See http://www. Omim. Org/ ...Read more

Is high fructose corn syrup unhealthy?

Is high fructose corn syrup unhealthy?

The real health problem with hfcs is that because of its sugar contents, it is a major contributor to obesity and its consequences such as type ii diabetes. ...Read more
