The Claim

Higher consumption of red and processed meat is associated with a 23% increased risk of developing chronic kidney disease over a 23-year period in middle-aged adults with normal kidney function, compared to individuals with the lowest intake.

In plain English

People who eat more red and processed meat over 23 years have a 23% higher chance of developing chronic kidney disease than those who eat the least, even when total protein intake is accounted for.

See the scientific wording

Higher consumption of red and processed meat is associated with a 23% increased risk of developing chronic kidney disease over 23 years in middle-aged adults with normal kidney function, compared to those with the lowest intake, suggesting that dietary protein source may influence long-term kidney health independently of total protein intake.

Why this might work

Eating red and processed meat introduces more acidic compounds and sulfur-containing amino acids into the body. The kidneys respond by filtering blood at a higher rate to remove these substances, which puts extra pressure on the tiny filtering units in the kidneys. Over time, this constant high pressure damages the filtering structures, causing them to scar and lose function, which leads to permanent kidney decline.

  1. Study: Dietary protein sources and risk for incident chronic kidney disease: Results from the Atherosclerosis Risk in Communities (ARIC) Study

    People who ate a lot of red meat and processed meats like bacon were 23% more likely to develop kidney problems over 23 years, even if they ate the same total amount of protein as others. Eating nuts, beans, or low-fat dairy instead was linked to lower risk.
