Fact-Check: "Juicing can damage kidneys"
What We Know
Juicing, particularly with high-oxalate vegetables and fruits, has been linked to kidney damage in certain cases. A notable study published in 2022 describes a case of a 68-year-old man who developed severe acute oxalate nephropathy (AON) and end-stage renal disease (ESRD) after consuming a daily diet rich in oxalate from juicing vegetables like spinach and Swiss chard. His dietary intake of oxalate was approximately 1500 mg per day, which is about ten times the typical dietary intake. The renal biopsy showed extensive tubular oxalate deposits and acute tubular damage, leading to his dialysis dependence one year later (Chaudhari et al., 2022).
Another case study from 2018 reported a 65-year-old woman who also developed acute kidney injury after consuming an oxalate-rich green smoothie cleanse. This case highlighted that such juice cleanses can increase oxalate absorption, particularly in individuals with predisposing risk factors such as a history of gastric bypass surgery (Makkapati et al., 2018).
Additionally, a blog post from Colorado State University notes that prolonged juicing can lead to nutrient deficiencies and malnutrition, and emphasizes that some foods used for juicing may be high in oxalates, which can negatively affect kidney health (Colorado State University).
Analysis
The evidence supporting the claim that juicing can damage kidneys is substantial, particularly in the context of high-oxalate diets. The studies referenced provide specific case examples where individuals developed serious kidney conditions as a direct result of excessive oxalate intake from juicing.
The reliability of these sources is high; they are peer-reviewed studies published in reputable medical journals. The 2022 study by Chaudhari et al. is particularly compelling as it details the clinical progression of a patient who developed ESRD due to juicing, providing a clear causal link between high oxalate intake and kidney damage. Similarly, the 2018 study by Makkapati et al. corroborates these findings by presenting another case of acute kidney injury associated with juicing.
Moreover, the blog from Colorado State University offers a broader perspective on the potential risks of juicing, emphasizing the importance of moderation and awareness of dietary oxalate content. This aligns with the findings of the case studies, reinforcing the idea that while juicing can have health benefits, it can also pose significant risks, particularly for susceptible individuals.
Conversely, some sources suggest that juicing can be beneficial for kidney health, particularly in moderation. However, these claims often lack the same level of empirical support as the studies linking juicing to kidney damage. For instance, a recent article from Today discusses the potential for high-oxalate juices to harm kidneys, further supporting the caution advised regarding juicing practices (Today).
Conclusion
The claim that "juicing can damage kidneys" is True. Evidence from multiple case studies indicates a clear association between high oxalate intake from juicing and the development of acute kidney injury and chronic kidney disease. The studies highlight the risks associated with excessive consumption of oxalate-rich juices, particularly for individuals with pre-existing health conditions or dietary sensitivities. Therefore, while juicing can be a part of a healthy diet, it is crucial to be aware of the potential risks and to consume such juices in moderation.
