According to the National Institutes of Health (NIH), uric acid is not only a waste but also closely related to inflammatory reactions and oxidative stress.
When the body falls into a low-level chronic inflammation, kidney activity declines, reducing the ability to filter and excrete uric acid.
At the same time, oxidative stress stimulates the breakdown of endogenous purines, causing uric acid to continue to increase even if the diet is not too high in protein.
This explains why many people with increased uric acid, although eating "not too much", lack antioxidant micronutrients and minerals to protect the kidneys.
Brazil nuts are famous as the highest natural source of selenium in foods. According to a report by WHO and FAO, only 1-2 Brazil nuts can provide almost enough daily selenium needs for adults.
According to the overview on Nutrients, these nutrients play an important role in reducing inflammation, improving vascular endothelial function and protecting kidney aggregates, key factors related to metabolism and uric acid excretion.
Brazilian seeds are only beneficial when eaten very regularly, as high selenium content can be harmful if abused. Recommendations include:
Only 1-2 grains/day, do not eat continuously in large quantities
Eat whole seeds, not roasted with salt or seasoned
Combine with a diet rich in green vegetables and whole grains
Do not use as "treating food" instead of medicine
People with severe kidney failure, who are supplementing selenium from medication or have thyroid diseases should consult a doctor before using it regularly.
According to an analysis in the American Journal of Clinical Nutrition (2024), a diet rich in nuts and nuts, including Brazil nuts in appropriate amounts, helps reduce chronic inflammation, improve metabolic index and reduce the risk of cardiovascular complications in people with hyperuricemia.
This is an important factor, because gout is not only a joint disease but also closely related to the heart and kidneys.
