A healthy dietary pattern may prevent chronic kidney disease (CKD) and albuminuria, according to a new analysis published in the Clinical Journal of the American Society of Nephrology.
Researchers examined data from 18 studies with 630,108 participants without CKD at baseline to evaluate the associations between dietary patterns and the incidence of CKD.
They found a healthy dietary pattern, such as those which were rich in whole grains, vegetables, fruit, legumes, nuts and fish and had a lower intake of red and processed meats, sodium and sugar-sweetened beverages, was associated with a lower incidence of CKD (odds ratio [OR] 0.70; 95% CI 0.60-0.82; I2=51%; eight studies) and incidence of albuminuria (OR 0.77; 95% CI 0.59-0.99; I2=37%); four studies).
There did not appear to be any significant association between healthy dietary patterns and decline in estimated glomerular filtration rate (eGFR).
The authors said the findings add to the accumulating evidence base supporting the benefits of adherence to healthy dietary patterns for chronic conditions.
“On the basis of the findings from this review, a healthy dietary pattern (possibly the Mediterranean diet) and/or interventions testing the effectiveness of dietary guidelines need to be studied in randomised controlled trials,” they concluded.
