Dietary Acid Load May Predict Risk of CKD

A recent study found poverty, black race, and being male were significantly linked with an increasing level of estimated net acid excretion (NAEes), a measure of dietary acid load. Analysis of >12,000 adults aged 40 to 60 years in NHANES 1999–2004 noted higher levels of NAEes, which compared to lower levels, were associated with a 1.57 greater odds of albuminuria. Investigators also observed a trend toward greater NAEes with higher risk of low eGFR. The BMC Nephrology findings suggest dietary acid load may be an important target for future interventions in populations at high risk for CKD.
