Dietary Patterns May Influence Kidney Health

Worse function seen in those whose diets have more red and processed meats, sweets

THURSDAY, Feb. 24 (HealthDay News) -- A diet high in red and processed meats and sweets may lead to microalbuminuria and rapid kidney function decline, but a diet high in fruits, vegetables, and whole grains may protect against rapid estimated glomerular filtration rate (eGFR) decline, according to research published in the February issue of the American Journal of Kidney Diseases.

Julie Lin, M.D., M.P.H., of Harvard Medical School in Boston, and colleagues collected data on dietary patterns and eGFR changes in 3,071 individuals (primarily older white women) to see if there was an association between dietary patterns and microalbuminuria or a decrease in kidney function.

The researchers found the highest association of microalbuminuria and rapid eGFR decline in participants with a Western dietary pattern (more red and processed meats, saturated fats, and sweets). A decreased risk for eGFR decline, but no association with microalbuminuria, was seen in those with a Dietary Approach to Stop Hypertension (DASH) pattern (more vegetables, fruits, and whole grains).

"A Western dietary pattern is associated with a significantly increased odds of microalbuminuria and rapid kidney function decrease, whereas a DASH-style dietary pattern may be protective against rapid eGFR decline," the authors write.
