According to Gram Research analysis of a 2026 prospective cohort study of 5,325 people with gout and high uric acid, eating foods that support healthy gut bacteria reduced all-cause mortality risk by 33% and cardiovascular death risk by 45% over 6.5 years. Each one-point increase in the Dietary Index for Gut Microbiota score was associated with an 8% decrease in all-cause mortality and 13% decrease in cardiovascular mortality, suggesting that gut-friendly dietary patterns may significantly improve survival in this high-risk population.
A Gram Research analysis of over 5,300 people with gout and high uric acid found that eating foods that support healthy gut bacteria significantly reduced their risk of dying from any cause and from heart disease. The study tracked participants for about 6.5 years and measured their diets using a scoring system that rates foods based on how they affect gut health. People who scored highest on this gut-friendly diet scale had a 33% lower risk of dying overall and a 45% lower risk of dying from heart problems compared to those who scored lowest. This suggests that making specific dietary changes could be a powerful way to improve survival and heart health for people dealing with gout.

The Quick Take
- What they studied: Whether eating foods that are good for your gut bacteria helps people with gout and high uric acid live longer and healthier lives
- Who participated: 5,325 adults with gout or high uric acid levels who were part of a national health survey conducted between 2007 and 2018
- Key finding: People who ate the most gut-friendly foods had a 33% lower chance of dying from any cause and 45% lower chance of dying from heart disease over 6.5 years, compared to those who ate the least gut-friendly foods
- What it means for you: If you have gout or high uric acid, changing your diet to include more foods that feed good gut bacteria may significantly improve your chances of living longer and avoiding heart problems. However, diet alone isn’t a cure—work with your doctor on a complete treatment plan
The Research Details
Researchers followed 5,325 people with gout or high uric acid for an average of 6.5 years, tracking what they ate and whether they died during that time. They used a special scoring system called the Dietary Index for Gut Microbiota (DI-GM) that rates 14 different food components—10 that are good for gut bacteria and 4 that are harmful. The scores ranged from low to high based on how much of each food component people ate.
The researchers calculated each person’s DI-GM score using detailed food records from a single day, then followed up to see who died and from what cause. They used death records from the National Death Index to track outcomes through the end of 2019. The study carefully adjusted for other factors that affect mortality, like age, smoking, exercise, and existing health conditions, to make sure the diet score itself was responsible for the differences they found.
This approach is powerful because it follows real people over time rather than just comparing groups at one point in time, which helps show whether diet changes can actually predict better health outcomes.
This study design is important because it shows real-world results in people who actually have gout and high uric acid—the exact population that needs help. By following people over years and measuring their actual food intake, researchers can see whether diet really makes a difference in survival. The study also looked at a large, nationally representative group, which means the findings likely apply to many different types of people.
This study has several strengths: it included a large, diverse group of over 5,300 people; it followed them for many years; it adjusted for many other health factors that could affect the results; and the findings stayed consistent when researchers tested them different ways. One limitation is that diet was measured from just one day of food records, which may not represent someone’s typical eating pattern. The study also cannot prove that changing diet will definitely improve outcomes—it only shows an association between better diets and better survival.
What the Results Show
During the 6.5-year follow-up period, 603 people died, including 197 from heart disease. People with the highest DI-GM scores (6 or higher) had a 33% lower risk of dying from any cause compared to those with the lowest scores (4 or lower). Even more impressive, the highest-scoring group had a 45% lower risk of dying specifically from heart disease. For every single point increase in the DI-GM score, people had an 8% lower risk of dying overall and a 13% lower risk of dying from heart problems.
These benefits appeared across all groups tested—the results held true whether researchers looked at men or women, younger or older people, or people with different body weights. The findings also remained strong when researchers tested the data in different ways to make sure the results were reliable. This consistency suggests that the gut-friendly diet pattern genuinely helps protect people with gout and high uric acid, rather than the results being due to chance or other hidden factors.
The study found that the protective effects of the gut-friendly diet were particularly strong in people with heart disease risk factors. The diet’s benefits appeared consistent across different age groups and body types, suggesting it could help a wide range of people with gout. The researchers also found that the relationship between diet quality and survival was dose-dependent, meaning that each improvement in diet quality provided additional protection.
Previous research has shown that gut bacteria play an important role in controlling inflammation and uric acid levels, both of which are problems in gout and high uric acid. This study is one of the first to directly test whether a diet designed to support healthy gut bacteria actually improves survival in people with these conditions. The findings align with earlier research showing that dietary patterns affect heart disease risk, but this study specifically demonstrates the benefit in the gout population, which has been understudied.
The study measured diet from just one day of food records, which may not reflect what people typically eat. The researchers could not randomly assign people to different diets, so they cannot prove that changing diet will definitely improve outcomes—only that better diets are associated with better survival. The study also relied on people remembering what they ate, which can be inaccurate. Additionally, the study cannot explain exactly how the gut-friendly diet works to reduce death risk, though the researchers believe it involves improving gut bacteria and reducing inflammation.
The Bottom Line
If you have gout or high uric acid, consider working with a doctor or dietitian to increase foods that support healthy gut bacteria, such as fiber-rich vegetables, whole grains, legumes, and fermented foods, while reducing processed foods and added sugars. The evidence is strong that this dietary pattern is associated with better health outcomes. However, diet should be part of a complete treatment plan that may include medication and other lifestyle changes prescribed by your doctor.
This research is most relevant to people with gout or high uric acid who want to reduce their risk of heart disease and early death. It may also interest people with family histories of gout or heart disease who want to prevent these conditions. People without gout or high uric acid may still benefit from a gut-friendly diet, but this study specifically tested people with these conditions.
The study followed people for an average of 6.5 years to see mortality benefits, but improvements in inflammation and gut health may begin within weeks to months of dietary changes. You should not expect to feel dramatically different immediately, but consistent dietary improvements over months and years appear to provide significant protection against serious health outcomes.
Frequently Asked Questions
Can changing my diet help me live longer if I have gout?
Research shows that eating foods supporting healthy gut bacteria is associated with a 33% lower risk of death from any cause in people with gout. While diet alone isn’t a cure, it appears to be a powerful tool when combined with medical treatment prescribed by your doctor.
What specific foods should I eat to support my gut bacteria if I have high uric acid?
Focus on whole grains, vegetables, fruits, legumes, nuts, fish, yogurt, cheese, tea, and coffee. Limit red meat, processed meat, sugar-sweetened beverages, and refined grains. These food choices support beneficial gut bacteria that may help reduce inflammation and improve heart health.
How quickly will a gut-friendly diet improve my gout symptoms?
While inflammation markers may improve within weeks to months, the study tracked people for 6.5 years to measure survival benefits. Consistent dietary improvements over months and years appear to provide the most significant protection against serious health outcomes like heart disease.
Does this diet work for people without gout who want to prevent it?
This study specifically tested people with existing gout and high uric acid, so we cannot say for certain it prevents gout in healthy people. However, the same gut-friendly foods support overall heart and digestive health, making them beneficial for anyone regardless of gout status.
Is diet enough to treat gout, or do I still need medication?
Diet should complement, not replace, medical treatment. The study shows diet is associated with better outcomes, but people with gout typically need medication to manage uric acid levels. Work with your doctor to combine dietary changes with appropriate medical therapy.
