This contrasts with studies in overweight/obese or insulin-resistant subjects in which metabolic effects from fructose or sucrose are commonly observed [22, 26, 55–58]. One potential explanation may relate to the absorption of fructose, which is known to increase with fructose exposure . Fructose effects are also potentiated by glucose , and most studies have only examined fructose alone.

Several studies have shown that individuals eating cherries or drinking cherry juice had fewer gout attacks than if they didn’t consume them. The compounds found in cherries responsible for reducing gout are anthocyanins and bioflavonoids, both which fight inflammation and help reduce uric acid levels. Eating 10 to 12 cherries a day can result in a 35% lower risk of another gout attack along with drinking tart cherry juice daily may also lower uric acid levels.

Gout that goes untreated can lead to worsening pain and joint damage. Seek medical care immediately if you have a fever and a joint is hot and inflamed, which can be a sign of infection. After the most severe pain subsides, some joint discomfort may last from a few days to a few weeks. An attack of gout can occur suddenly, often waking you up in the middle of the night with the sensation that your big toe is on fire. The affected joint is hot, swollen and so tender that even the weight of the bedsheet on it may seem intolerable. Gout is a common and complex form of arthritis that can affect anyone.

Fructose is rapidly phosphorylated in the hepatocyte by KHK to fructose-1-phosphate (F-1-P), which uses ATP as a phosphate donor. Intracellular phosphate levels decrease, stimulating the activity of AMP deaminase 2 .

Similarly, data from the MRFIT showed that male participants with gout had a 26% increased risk for incident type 2 diabetes . The substantial increase in soft drink and fructose consumption coincided with the increasing trend of serum uric acid and doubling of the disease burden of gout over the past few decades in the US . Fructose is known to induce uric acid production by increasing ATP degradation to AMP, a uric acid precursor and thus, within minutes after fructose infusion, serum uric acid levels rise . Furthermore, de novo purine synthesis is accelerated, further potentiating uric acid production.

Concerns With Animal Studies

In a study of 633 gout sufferers followed for a year, those who had eaten cherries in the past few days were 35% less likely to have an acute gout attack than those who hadn’t. In fact, gout is one of the few treatable and preventable forms of arthritis, an umbrella term for dozens of conditions that cause inflammation in the joints. The challenge is making sure people get the gout care they need and follow through on taking medications.

Why does fructose cause hyperuricemia?

Briefly, fructose metabolism effectively boosts the production of uric acid. It weakens the excretion of uric acid, and the overproduction and underexcretion of uric acid are significant contributors to gout and hyperuricemia [49].

Physicians should be aware of the potential effect of these beverages on the risk of gout, a common and excruciatingly painful arthritis. One paradox is that the acute elevation of serum uric acid by infusion often results in an improvement in endothelial function . However, while uric acid is an antioxidant in the extracellular environment, it has prooxidative effects inside the cell . For example, high-dose allopurinol improves endothelial dysfunction in subjects with heart failure whereas the lowering of uric acid with probenecid was ineffective .

Thus, the potential causal role of serum uric acid on these outcomes remains to be clarified further by future studies. In particular, additional randomized trial data on the effect of various urate-lowering medications (e.g. with or without xanthine oxidase inhibitor related properties) on the prevention or treatment of these outcomes would be valuable. Previous studies have found that high doses of vitamin C supplementation lower serum uric acid via a uricosuric effect (77–81). A double-blinded placebo-controlled randomized trial among 184 non-smoking participants showed that supplementation with 500 mg/day of vitamin C for 2 months reduced serum urate levels by 0.5 mg/dL (95% CI 0.3 to 0.6) . Several observational studies from Taiwan and from the US extended the evidence for the inverse link between Vitamin C intake and the lower risk of hyperuricemia or gout. Fructose is often added to food because it is both cheap and enhances taste.

In this study, 73 patients were randomly assigned to a group to either ingest small or large servings of apples, small or large servings of apple juice, or a sugar-sweetened beverage. The researchers collected blood samples of these individuals at baseline, 30 minutes after consumption, and 60 minutes after consumption. Body mass index was calculated as updated weight in kilograms divided by baseline height in meters squared. In the classical pathway, triglycerides are a direct product of fructose metabolism by the action of multiple enzymes including aldolase B and fatty acid synthase . As a consequence, the ACO2 substrate, citrate, accumulates and is released to the cytosol where it acts as substrate for TG synthesis through the activation of ATP citrate lyase and fatty acid synthase.

Fast on its heels, insulin rushes into your bloodstream to direct glucose traffic and bring your blood sugar back down. Fatty fishes, such as tuna and salmon, are generally considered a healthy, nutritious addition to the diet, mostly due to the heart-healthy omega-3 fatty acids they contain. However, due to their higher purine content, it is currently recommended to limit these foods if you have gout.

In supermarkets across the country, we have access to almost any fruit we want year-round. What if our bodies are not designed to deal with this much sugar all the time? There is something to be said about eating seasonally and listening to our bodies as to what we need when we need it.

Does fructose increase uric acid?

Finally, fructose stimulates the production of uric acid. When ATP is consumed, adenosine monophosphate (AMP) accumulates and stimulates ATP deaminase, which then triggers the production of uric acid, which can induce the accumulation of triglycerides.

The DASH diet is popular in many countries and cookbooks are available in various languages using local foods. Despite the above reports on SUA there is no clear causal link between fructose intake and metabolic disorders such as diabetes, obesity and the metabolic syndrome. Some researchers have suggested that the causal factor may be upregulated XO activity rather than increased SUA while other researchers have suggested that the causal factor may elevated intracellular uric acid . The relationship of elevated uric acid to diabetes has been described since the 1800s.

Gout occurs when urate crystals accumulate in your joint, causing the inflammation and intense pain of a gout attack. Urate crystals can form when you have high levels of uric acid in your blood. Your body produces uric acid when it breaks down purines — substances that are found naturally in your body.

However, there is no reason to believe that these metabolic differences make ordinary amounts of fructose any worse than ordinary amounts of glucose when it comes to ATP reserves, fat production, or uric acid levels. Fructose byproducts are identical to glucose byproducts and can turn into all of the same things that glucose can. Fructose, as well as the high-fructose corn syrup added to some foods, can increase serum uric acid levels. Avoiding or limiting foods high in these sugars may help lessen the symptoms of gout. If increased carbohydrate intake leads to more insulin resistance and insulin resistance seems to cause elevated uric acid levels and gout in patients, then does a reduction in carbohydrates seem to improve the outcome of gout? L-arginine works together with l-glutamine in the small intestine to facilitate cell proliferation, to limit the inflammatory response and apoptosis, and to modulate intermediary metabolism through specific transcription factors .

Before we analyze these studies, it is important to understand the complexity related to their interpretation. First, many clinical studies use fructose alone—and often at relatively high doses—in order to evaluate the effects of fructose per se. This allows one to directly address the effects of fructose, and the use of high doses is a common experimental approach to allow one to identify metabolic effects that could otherwise take much longer periods to show.
