People who get higher levels of omega-3s from seafood are less likely to develop kidney disease. This review of 19 studies from 12 countries covered 25,570 participants, about one in five of whom developed chronic kidney disease (CKD) over 11.3 years of follow-up.
Those who got the most seafood in the diet were 13 percent less likely to develop CKD. All three omega-3s; EPA, DHA, and DPA, had links to better kidney health. Plant-based omega-3s did not influence CKD.
The healthy kidney filters blood to remove waste and extra water to make urine. Doctors determine CKD by monitoring how well kidneys perform the filtration function.
