The Claim

In long-term hemodialysis patients, a dietary omega-6 to omega-3 fatty acid intake ratio in the range of 11.3–17.4 is associated with a 61% higher risk of death over six years compared to a ratio of 1.7–<7.6.

In plain English

Among patients on long-term hemodialysis, those consuming a diet with a higher ratio of omega-6 to omega-3 fatty acids had a 61% higher rate of death over six years than those consuming a lower ratio.

See the scientific wording

In long-term hemodialysis patients, those in the highest quartile of dietary omega-6 to omega-3 intake (11.3–17.4) had a 61% higher risk of death over six years compared to those in the lowest quartile (1.7–<7.6), though this trend did not reach statistical significance (p=0.06).

Why this might work

When a person eats a lot more omega-6 fat than omega-3 fat, their cells use more omega-6 to build cell membranes. This leads to the production of strong inflammatory chemicals that cause blood vessels to narrow, blood to clot more easily, and the liver to release more inflammation markers. Over time, this constant inflammation damages the heart and blood vessels, increasing the chance of death.

    People on long-term dialysis who ate a lot more omega-6 fat than omega-3 fat tended to die more often over six years, though the data wasn’t quite strong enough to be 100% sure. The study also found these diets made inflammation worse, which might explain why they’re riskier.
