Research: Don't Know How to Prevent Kidney Failure, Eat This Way!

A study recently published in the medical journal Renal Failure has found a diet that can help reduce the risk of chronic kidney disease (CKD).

Researchers from the University of Electronic Science and Technology of China analyzed data from the US National Health and Nutrition Examination Survey (NHANES) from 2000 to 2020. A total of 46,742 people were included in the analysis, with an average age of nearly 50 years. Of these, 8,340 were diagnosed with chronic kidney disease, while the remaining 38,402 were disease-free.

The authors evaluated the effects of four diets on the risk of chronic kidney disease.

The results found that the diet that really helps reduce the risk of chronic kidney disease is the "DASH" diet, according to the medical news site Medical Xpress.

Conversely, they also found that the "inflammatory" DII diet not only increased the risk of kidney disease but also made people with kidney disease have a 26.4% higher risk of developing severe disease.

These effects are more pronounced in men, people over 65 years old, and people with high blood pressure.

Why does the DASH diet help protect the kidneys?

The DASH diet is a diet based on fruits, vegetables, whole grains, and low-fat dairy. However, it also has clear benefits for the kidneys. This diet limits sodium, saturated fat, and alcohol, thereby reducing pressure on the glomeruli and reducing endothelial damage; increasing potassium helps increase sodium excretion, helping to protect the glomerular filtration membrane.

The DASH diet, which includes magnesium from nuts and beans, helps reduce inflammation and kidney fibrosis.

The strategy of combining limiting harmful substances and increasing beneficial substances in the DASH diet helps maintain kidney function through many mechanisms: reducing oxidative stress, stabilizing eGFR (glomerular filtration function), and reducing the albumin/creatinine ratio in urine.

The study authors concluded that the DASH diet may help optimize strategies for preventing and treating kidney disease more effectively, according to Medical Xpress.

DASH Diet

Leading health organizations are backing the DASH diet for its health benefits. The National Kidney Foundation; the National Heart, Lung, and Blood Institute; the American Heart Association; and the Dietary Guidelines for Americans all recommend the DASH diet.

However, people with chronic kidney disease should talk to their doctor before starting any new diet. The DASH diet should not be used by people on dialysis.

Inflammatory diet

An inflammatory diet is characterized by foods that tend to increase inflammation in the body. Key factors in an inflammatory diet include high consumption of processed foods, refined carbohydrates, sugary drinks, red meat, processed meats, etc.
