Because CKD can later progress to kidney failure with its incredibly destructive effects on quality of life, it is important to find simple ways to prevent and treat it.
A new study published in BMJ may have found the simplest of them all.
All you need to do is load up on one type of common food, one that most of us consider a total treat.
A multinational research team led by the George Institute for Global Health and the University of New South Wales wanted to know whether omega-3 polyunsaturated fatty acids circulating in the bloodstream could prevent CKD. They studied both plant and marine-derived omega-3s.
They reviewed data from 19 studies in 12 different countries with 25,570 participants altogether, all between ages 49 and 77.
Of the 25,570 participants, 4,944 (19.3 percent) developed CKD during the 11-year observation period.
The analysis yielded the following results.
-
1. Higher levels of omega-3 fatty acids from marine sources were linked to an 8% lower risk of developing CKD.
2. Compared with those who consumed the least fish, those who consumed the most had 13% reduced CKD risk.
3. Those who ate the most fish and already had CKD experienced a much slower decline in kidney function.
4. Plant-derived omega-3, called alpha-linolenic acid, had no effect on CKD risk or kidney function decline.
