A growing body of research has highlighted the potential health benefits of plant-based diets in reducing the risk of gout. According to two major cohort studies recently covered by Medscape, consistently higher dietary intakes of specific lignans—phytoestrogen compounds found abundantly in plant foods—and lignan-rich whole grain foods are associated with a reduced risk of developing gout.
Lignans are natural compounds most commonly found in seeds (especially flaxseed), whole grains, fruits, and vegetables. They are metabolized by gut microflora, which may play a role in modulating inflammation and metabolic processes.
Researchers analyzed dietary intake data from more than 120,000 participants in the Health Professionals Follow-up Study and the Nurses’ Health Study. By regularly collecting food frequency questionnaires over several years, the investigators were able to isolate the effects of different types of plant-based foods and specific lignans on the risk of developing gout:
-
Higher intakes of matairesinol and secoisolariciresinol—two types of lignans found in many whole grains and seeds—were each associated with a 22% lower risk of gout when comparing the highest with the lowest intake groups.
-
Whole grain cold breakfast cereals, cooked oatmeal/oat bran, and added bran were also linked to a significantly reduced risk of gout, while whole wheat bread and other cooked cereals did not show such a strong association.
The results reinforce existing dietary guidelines encouraging the consumption of whole plant foods:
-
such as oats and high-fiber cereals may provide additional protection against gout beyond their known cardiovascular and metabolic benefits.
-
can also help prevent other health complications connected to gout, like obesity and heart disease.
Researchers suggest that the observed impact may, in part, be due to the positive effect of these foods on the gut microbiome, which influences inflammation and uric acid metabolism1.
For individuals concerned about gout, experts recommend:
-
Focusing on whole grains, fruits, vegetables, legumes, and nuts
-
Limiting red meat, organ meats, high-purine seafood, alcohol, and sugar-sweetened beverages
-
Prioritizing weight management and regular physical activity
While whole grains contain moderate levels of purines, studies consistently show their benefits outweigh potential risks for most people—even those with gout.
Conclusion
Emerging evidence supports the notion that incorporating lignan-rich plant foods and whole grains into the daily diet could help lower the risk of gout. This adds another reason to embrace healthy, diverse plant-based eating patterns.

Individuals should consult their healthcare provider before making significant dietary changes, especially if they are at risk for or managing gout or other metabolic conditions.
