Chronic kidney disease (CKD) is mostly caused by the western type diet we’re all overexposed to.
You’ve therefore probably received a long list of things to NOT eat. Like too much sugar, salt, potassium, and overall too many calories.
But, instead of telling us what to avoid, a new study in Kidney Medicine now tells us what to load up on to tackle CKD, and it all comes down to a specific type of flesh.
The research, carried out on 3,726 people who were part of the Atherosclerosis Risk in Communities study, set out to explore a fascinating question: can the proteins we consume, from sources like fish, nuts, eggs, and meats, have a direct relationship with our risk of developing (CKD)?
The idea here wasn’t just to measure how much protein their participants ate, but rather to explore and identify specific markers in their blood that could tell researchers about the types of protein they ate.
To find out, they used a technique called untargeted metabolomics, which is the process of scanning for thousands of small molecules (metabolites) in the blood that result from the digestion and processing of the foods we eat.
Together with this blood metabolite scan, they also checked which of their subjects developed CKD, hospitalization or death because of CKD, or end-stage kidney disease.
Out of the six protein sources studied (fish, nuts, legumes, red and processed meats, eggs, and poultry), 30 associations were identified between these foods and specific metabolites in the participants’ blood.
How did these metabolites relate to CKD?
-
1. There was one fish-related metabolite, called 1-docosahexaenoylglycerophosphocholine (22:6n3), which showed a protective effect against CKD.
2. With every increase in the level of this fish-related metabolite, the risk of CKD decreased by 18%.
3. The other protein-related metabolites showed no link with CKD.
This is a very interesting study. The main finding is obviously that fish consumption might prevent the occurrence of CKD.
The researchers concluded that their study supported nutritional guidelines that recommended the Mediterranean diet, since fish is its main source of protein.
Salmon, tuna, mackerel, sardines, herring, sea bass, cod, Sea Bream, and different types of shell fish are all popular options in Mediterranean cuisine.
