Fructokinase C has been especially noted to facilitate this fat accumulation in the liver via uric acid generation, a decrease of ATP, and increased nucleotide turnover. Still, there are contradictory findings in some studies that suggest fructose consumed over shorter durations or in lower doses may not express these relationships. An important question is whether chronic fructose ingestion may be responsible for persistent elevations in blood pressure.

Disagreement was resolved by discussion and, if required, by a fourth independent author. We have assessed the clinical and methodological heterogeneity across the studies and, where available, included meta-analyses whenever these have been performed.

Too much sugar during the day can mess with your blood glucose levels and cause energy spikes and crashes. In the evenings, a bowl of ice cream or cookies can pump you with sugar that can wake you up at night. Traditionally, gout prevention strategies have focused on limiting protein-rich foods and alcohol, which can encourage uric acid accumulation in the body.

Adding pineapple to your daily diet may help prevent gout flare-ups and reduce the intensity of your gout symptoms. Aim for one serving of pineapple, which is equal to one cup of fresh pineapple chunks. Avoid sugary drinks containing pineapple, or pineapple desserts. Pineapple is delicious when eaten fresh.

The Lesch–Nyhan syndrome is also associated with extremely high levels of uric acid. The results of the current study suggest that dietary guidelines and consumer choices should not be based on the assumption that all adverse effects from dietary sugars are due to fructose content. It appears that the secretions produced for digestion are the mechanism by which intestinal uric acid excretion occurs. L-glutamine is the preferred fuel for the enterocytes , as well as increasing renal pH, and therefore becomes the treatment of choice to support intestinal tissue health.

"There is an alarming trend of increased rates of obesity, type 2 diabetes and NAFLD in the U.S.," said lead author Dr. Manal Abdelmalek from Duke University Medical Center. "Given the concurrent rise in fructose consumption and metabolic diseases, we need to fully understand the impact of a high-fructose diet on liver function and liver disease." This survey also indicated that sodas without high fructose corn syrup were not associated with serum uric acid. This added support to the belief that the increased consumption of fructose can lead to an excess of uric acid in the blood. The consumption of too much sugar is associated with a number of health conditions such as obesity, heart disease and diabetes.

Although weight gain is largely controlled by overall energy intake, other features of metabolic syndrome can occur independent of weight gain. For example, rats fed fructose develop fatty liver, hypertriglyceridemia, and insulin resistance when compared with rats fed isocaloric glucose or starch-enriched diets . Indeed, hypertriglyceridemia, fatty liver, and type 2 diabetes can be induced in metabolic syndrome–prone rats with caloric restriction provided the diet is high (40%) in sucrose . A recent epidemiological analysis in humans also found an association of diabetes prevalence with sugar availability that was independent of total energy intake .

Several factors are required for cancer growth, including energy source, nucleotide, lipid, and redox balance. Fructose is metabolized through four pathways and contributes to meet the demand for cancer . The use of preparations for lowering SUA should be been clinically viewed primarily as an adjunct to dietary control. The number of clinical studies conducted with the various nutrients and herbals is often limited often to a single study, within a specific group, and this makes it difficult to generalise or predict treatment outcomes. Hopefully this compilation of potential treatments will stimulate further research with these substances, as well as, extending the knowledge base of clinicians.

Experimental studies from the 1950s showed the peculiar ability of fructose to induce insulin resistance in laboratory rats. Today, fructose intake has been shown to induce all features of metabolic syndrome in rats, as well as oxidative stress, endothelial dysfunction, fatty liver, microalbuminuria and kidney disease (rev. in 1). Similar findings can be shown when animals are fed sucrose or high-fructose corn syrup , both which contain fructose . In contrast, administration of glucose or starch results in fewer features of metabolic syndrome when provided equivalent intake . It is our hope that future studies will address the fructose and uric acid hypotheses. Specifically, studies are needed to determine the effectiveness of a low-fructose diet vs. other diets such as DASH or low-carbohydrate diets in the prevention or treatment of obesity and metabolic syndrome.

Precipitation of uric acid crystals, and conversely their dissolution, is known to be dependent on the concentration of uric acid in solution, pH, sodium concentration, and temperature. Weng et al. showed that compared to glucose, fructose was more potent to produce ATP and fatty acids for lung cancers . The causal role of fructose could be also supported for by the fact an increase in GLUT5 expression was associated with poor prognosis in patients with lung adenocarcinoma .

Yet, even this value may be too high, according to a study from Iran, where metabolic syndrome is highly prevalent at 30%. SUA and metabolic syndrome measurements were conducted in a group of untreated participants, where individuals with a history of cardiovascular disease, diabetes, cancer, stroke, kidney disease and gout were excluded. Those classified with metabolic syndrome had a mean SUA of 5.9 ± 1.5 mg/dl while the other participants had a mean SUA of 4.9 ± 1.3 mg/dl .

Eating a diet rich in red meat and shellfish and drinking beverages sweetened with fruit sugar increase levels of uric acid, which increase your risk of gout. Alcohol consumption, especially of beer, also increases the risk of gout. The research suggests intake of sugar sweetened sodas increases the risk of gout bye up to 2.4 times. The study also finds that the risk of gout was significantly increased with increasing intake of fructose – the main ingredient thought to cause the increased risk in sodas. Goncalves et al. investigated the effects of dietary fructose (~3% of total daily caloric intake) in adenomatous polyposis coli mutant mice, which are predisposed to develop intestinal tumors .

As stated above, fructose metabolism is very different compared with the other sugars. When fructose is metabolized, hepatic adenosine triphosphate is depleted, which causes the promotion of uric acid formation as well as the breakdown of nucleotides. Fructose is absorbed in the intestines and undergoes metabolism primarily in the liver but also in the kidneys and adipocytes.
