Good doctors and medical websites give diet advice.
They mean well… but… what they tell people suffering from chronic kidney disease (CKD) NOT to eat kills millions.
This is according to a new study published in JAMA Network Open.
For years, doctors have recommended limiting protein intake for CKD patients to slow the progression of the disease.
This is because proteins break down into waste products that the kidneys have to filter, which can put extra strain on already weakened kidneys.
However, the authors of this new study wondered whether this was actually correct. After all, older adults naturally need more protein to maintain muscle mass, strength, and energy levels. Not getting enough could lead to malnutrition and frailty, which can compromise the health and survival of elderly CKD patients.
So, they decided to investigate whether total, animal, and plant protein intake had any connection to mortality in older adults with mild or moderate CKD.
They gathered data from 8,543 people over the age of 60, living independently in Spain and Sweden. The participants were followed for up to 10 years, with their diets and protein intake tracked through detailed food questionnaires.
They discovered what they suspected they might:
-
1. Higher total protein intake lowered mortality risk in people with mild to moderate CKD.
2. Both plant and animal proteins offered the same protection, showing no difference in their effects.
So, eating more protein may help you live longer, even if it doesn’t help with CKD (may even be harmful).
The next logical question is: What food reverses CKD?
