Increase vegetables, fruits, and legumes; reduce red meat, processed meats, and refined grains. Adjust potassium if there is advanced CKD, under supervision.
In practice
Increase vegetables, fruits, and legumes; reduce red meat, processed meats, and refined grains. Adjust potassium if there is advanced CKD, under supervision.
Precautions
In advanced CKD it can raise serum potassium: requires supervision and blood tests.
Effect by goal · level of evidence
improves Moderate trials (AA)
↑ Bicarbonate without sodium
Reduces the net dietary acid load and improves serum bicarbonate in moderate CKD comparably to oral bicarbonate with less sodium.

↓ Albuminuria
In moderate CKD it reduces albuminuria and acid load; added cardiovascular benefit from less sodium.
