The 25,570 participants in the studies were between 49 and 77 years of age at the beginning of the study. Overall, 4,944, or 19.3 percent, developed incident chronic kidney disease in subsequent years, according to follow-up research conducted over 11 years. Participants in the studies who had higher levels of seafood-derived omega-3 in their diets had an 8 percent lower risk of developing chronic kidney disease, and those consuming the highest levels of omega-3s found only in seafood had a 13 percent lower risk of developing chronic kidney disease compared to those in the studies who had consumed the lowest levels of seafood-originated omega-3s.
