Higher dietary intake of plant protein is tied to lower risk of chronic kidney disease
South Korea: Greater intake of dietary plant protein was shown to be associated with a lower risk of incident chronic kidney disease (CKD) in a large, prospective cohort study published in the American Journal of Kidney Diseases.
Plant-based diets confer various health benefits, including lowering the risk of cardiovascular disease and certain cancers. However, the relationship between plant protein intake and the risk of chronic kidney disease (CKD) remains unclear. This study led by Ga Young Heo aimed to investigate the association between plant protein intake and the development of CKD.
The study included 117,809 participants who completed more than one dietary questionnaire and had an eGFR (estimated glomerular filtration rate) ≥60 ml/min/1.73 m2, a urinary albumin-to-creatinine ratio (UACR) <30 mg/g, and no history of CKD.
Key findings include:
· During a median follow-up of 9.9 years, incident CKD occurred in 3.2% of participants (incidence rate, 3.2 per 1,000 person-years). In a multivariable model, the adjusted hazard ratios (aHRs for the second, third, and highest quartiles of plant protein intake were 0.90, 0.83, and 0.82, respectively, compared with the lowest quartile.
Using the UK biobank study data, the researchers found that participants with a higher plant protein intake had a lower risk of developing CKD. This finding suggests that a higher dietary intake of plant-based protein may be beneficial for kidney health and provide insight into dietary interventions to prevent CKD in primary care settings.
