Introducing Omega-3: Your Kidney’s New Best Friend
Omega-3 fatty acids are like the popular kid in school that everyone wants to be friends with – and for good reason!
These friendly fats, particularly those found in seafood, have been linked to a lower risk of chronic kidney disease. They’re also associated with slower kidney function decline.
What’s interesting is that their plant-derived counterparts don’t show the same benefits. So it seems like our kidneys might be seafood lovers!
A Glimpse into Chronic Kidney Disease (CKD)
Chronic Kidney Disease, or CKD, is a worldwide health menace affecting around 700 million people.
Think about it – that’s almost twice the population of the United States! CKD can lead to complete kidney failure and even death, making it a top priority to find ways to prevent and slow down its progress.
Omega-3 and CKD: What’s the Connection?
Previous studies suggested that omega-3 polyunsaturated fatty acids, or n-3 PUFAs, might be good for kidney health. But how good are they? That’s what a team of scientists at The George Institute for Global Health set out to find.
Deep Diving into Data: The Big Omega-3 and CKD Study
In this study, the researchers didn’t just look at a few papers. They reviewed the results of 19 studies from 12 different countries, encompassing more than 25,000 participants!
These studies all measured levels of omega-3 fatty acids, focusing on four types: eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), docosapentaenoic acid (DPA), and alpha-linolenic acid (ALA).
Seafood, like oily fish, is rich in EPA, DHA, and DPA, while ALA is mostly found in plant-based foods like nuts, seeds, and leafy greens.
The Findings: Seafood Omega-3 to the Rescue!
So what did the data reveal? Well, higher levels of seafood-derived omega-3 fatty acids were linked to an 8% lower risk of developing CKD.
That’s not all – people with the highest levels of these fatty acids had a 13% lower risk of CKD compared to those with the lowest levels.
Not just that, higher levels of seafood omega-3s, particularly DHA, were linked to a slower decline in kidney function. However, the plant-based ALA wasn’t found to have a similar effect.
What Does This Mean for You?
The takeaway here is quite simple. If you want to do something good for your kidneys, consider including more seafood in your diet, following the current dietary guidelines.
And as the saying goes, the seafood you eat is likely to be better for your kidneys if it’s replacing less healthy foods.

This research, led by Kwok Leung Ong and the team, is another stepping stone in our understanding of kidney health and was published in The BMJ.
