DescriptionFructose, or fruit sugar, is a simple monosaccharide found in many plants, where it is often covalently linked to glucose to form the disaccharide sucrose. Fructose is one of three common dietary monosaccharides, along with glucose and galactose, that are absorbed directly into the bloodstream during digestion. Fructose is found naturally in many fruits and vegetables and honey. It is frequently derived from sugar cane, sugar beets, and corn. High-fructose corn syrup (HFCS), which is widely used as a sweetener in beverages and foods, is a mixture of glucose and fructose. The primary reason that fructose is used commercially in foods and beverages is because of its low cost and is its high relative sweetness. It is the sweetest of all naturally occurring carbohydrates being 1.73 times as sweet as sucrose. Fructose consumption in the U.S. has more than doubled in the past 30 years. Americans' fructose intake climbed from 15 grams per day in the early 1900s to 55 grams per day in 1994. This increase is largely due to an increase in soft drink consumption.

Toxicity Profile
Route of ExposureIngestion
Mechanism of ToxicityFructose is distinct from other sugars in its ability to cause intracellular ATP depletion, nucleotide turnover, and the generation of uric acid. Uric acid is generated via fructose due to its rapid phosphorylation (to fructose-1-phosphate) in the liver, leading to a rapid drop in free phosphate and ATP. This drop in ATP leads to the stimulation of adenosine monophosphate (AMP) deaminase which deaminates AMP to produce IMP, which is subsequently converted to uric acid (10). Uric acid is normally an anti-oxidant but without sufficient amounts of ascorbic acid (vitamin C) present in the plasma, it functions as a pro-oxidant. Because many soft drinks and foods that are sweetened with high fructose corn syrup do not contain vitamin C, the resulting uric acid can lead to a number of harmful effects, including gout, chronic inflammation, hypertension, increased adiposity, fatty liver disease and obesity (10). Many studies have shown that elevated uric acid levels are associated with several metabolic and cardiovascular conditions, including diabetes and coronary artery disease (10). Elevated serum uric acid has also been shown to be the most reliable predictor for the development of hypertension and incident renal disease (11) as well as fatty liver disease (12). Fructose-induced uric acid generation also causes mitochondrial oxidative stress that stimulates fat accumulation independent of excessive caloric intake (13). Several studies have demonstrated that oxidative stress is one of the earliest phenomena observed in vascular, renal, liver cells and adipocytes exposed to uric acid (11). High fructose consumption is also associated with more severe depletion of liver ATP, which may impair liver "energy balance”. High-fructose beverages have also been shown to lead to lower circulating insulin and leptin levels, and higher ghrelin levels. Since leptin and insulin decrease appetite and ghrelin increases appetite, some researchers suspect that eating large amounts of fructose increases the likelihood of weight gain.
MetabolismFree fructose is absorbed directly by the intestine. When fructose is consumed in the form of sucrose, it is digested (broken down) and then absorbed as free fructose. Fructose absorption occurs on the mucosal membrane via facilitated transport involving GLUT5 and GLUT2 transport proteins. Fructose is phosphorylated in the liver by fructokinase (Km= 0.5 mM). Fructokinase initially produces fructose 1-phosphate, which is split by aldolase B to produce the trioses dihydroxyacetone phosphate (DHAP) and glyceraldehyde. DHAP is then converted to glycerol-3-phophate which stimulates production of triglycerides. Nearly half (45%) of all pure fructose consumed is used up within 3-6 hours by the body for energy. If fructose is consumed with glucose (as it typically is in nature), up to 66% of it is used for energy within the same time frame. Roughly a third (29%) to a half (54%) of all fructose consumed is converted to glucose. Less than 1% of fructose appears to be directly converted to triglycerides.
Toxicity ValuesConsuming more than 100 g a day of pure fructose may lead to a modest but statistically significant rise in body weight of 0.44 kg a week. Consuming 100 g or more of fructose a day also significantly increases fasting levels of serum triglycerides. LD50: 15000 mg/kg (intravenous, rabbit)

Health EffectsAcute consumption of fructose or high fructose corn syrup is essentially non-toxic. Chronic, excess fructose consumption has been shown to be a cause (or indirect cause) of gout, insulin resistance, hypertension, obesity, fatty liver disease, elevated LDL cholesterol and elevated triglycerides, leading to metabolic syndrome. In Wistar rats, a laboratory model of diabetes, 10% fructose feeding as opposed to 10% glucose feeding was found to increase blood triglyceride levels by 86%, whereas the same amount of glucose had no effect on triglycerides. A 2008 study found a substantial risk of incident gout associated with the consumption of fructose or fructose-rich foods. It is suspected that the fructose found in soft drinks (e.g., carbonated beverages) and other sweetened drinks is the primary reason for this increased incidence.
