Chronic kidney disease affects more and more people
According to The Healthy, chronic kidney disease affects 10% of adults worldwide, causing 1.2 million deaths annually. In Hungary, an estimated 1.5 million people live with this condition—that’s about one in ten Hungarians. What’s especially concerning is that by 2040, it could become the fifth leading cause of death globally.
The study highlights that chronic kidney disease is among the fastest-growing causes of death. Currently, there’s no cure; treatment mainly focuses on slowing kidney damage by managing underlying causes, notes the Mayo Clinic.
Researchers have encouraging news
A new study published in the journal Renal Failure sheds light on a little-explored link: how a diet rich in live microorganisms affects the risk of chronic kidney disease, The Healthy points out. Over 12,000 American adults participated, and the results are surprisingly hopeful.
These foods could be incredibly valuable
Researchers categorized participants’ diets based on how much they consumed foods containing live microorganisms—like certain yogurts, pickles, cheeses, or fermented vegetables.
Those who regularly ate these foods faced a significantly lower risk of developing kidney disease. And you don’t need to eat huge amounts; even moderate consumption brought noticeable benefits.
- a few servings of plain yogurt with live cultures each week,
- occasionally enjoying sauerkraut or fermented vegetables,
- an occasional serving of kefir, kimchi, or kombucha,
- and sometimes eating cheeses with live cultures (like feta, mozzarella, or camembert—if unpasteurized).
This means you don’t have to eat fermented foods daily, but they should appear regularly—at least weekly—in your diet.
The significance of this discovery is underscored by the researchers’ note that this is the first large-scale, population-based study in the U.S. showing that lower rates of chronic kidney disease are linked more to diets rich in live microorganisms than to specific probiotic supplements.
It could mark a new nutritional approach
Experts say these findings suggest that diets rich in live microorganisms offer a fresh dietary strategy for managing kidney disease. In other words, it’s not just about probiotic capsules—you need real, natural fermented foods that have been part of traditional diets for centuries.

How to easily add more to your diet
If you’re ready to bring more live microorganisms into your meals, here’s the good news: small changes can make a big difference, like:
- swap sugary yogurts for plain yogurt with a drizzle of honey or fresh fruit,
- try sauerkraut, kimchi, or fermented veggies—remember, even a few bites count,
- choose cheeses that contain live cultures,
- and if you’re up for it, dive into homemade pickling—a fun and healthy hobby.
The key is to be mindful and remember: small daily habits add up to big health benefits over time—especially when you include delicious foods and drinks rich in live cultures. Just be sure to tailor everything to your body and current health needs!
