In a 5-year prospective cohort of 121 ambulatory patients with newly diagnosed cirrhosis, higher dietary fat intake was dramatically associated with all-cause mortality. Patients in the highest versus lowest tertile of total fat intake faced a nearly 7-fold increased mortality risk (HR = 6.69), while high saturated fatty acid (SFA) intake carried an 8.2-fold risk and elevated omega-6 (PUFA-6) intake a 5.24-fold risk. Notably, MUFA, total PUFA, and omega-3 intake showed no significant associations. Fifty deaths occurred across the 60-month follow-up — a 41.3% mortality rate underscoring the severity of this population's prognosis.
For the broader dietary-fat and liver-disease field, these findings are striking but must be interpreted cautiously. The cohort is small (n=121), and with 50 events and multiple fatty acid sub-analyses, the risk of spurious associations is real — the authors themselves label this exploratory and hypothesis-generating. Importantly, cirrhosis patients are a distinct metabolic population: their impaired lipid metabolism, altered gut microbiome, and systemic inflammation may amplify fat-induced hepatic stress in ways irrelevant to healthy adults. The omega-6 finding adds nuance to debates around vegetable oil consumption, but residual confounding from diet quality overall cannot be excluded. For clinicians managing cirrhotic patients, this reinforces cautious attention to dietary fat composition — a largely underexplored lever in hepatology practice — while larger confirmatory trials remain urgently needed.
