Food jetlag linked to increased cardiovascular risk in men

A study conducted by researchers from Inserm, INRAE, and several French universities has identified a link between ‘food jetlag’ and an increased risk of cardiovascular disease in men. Food jetlag refers to the discrepancy between meal times during the work week and those during weekends or rest days.

Analyzing data from over 100,000 participants in the NutriNet-Santé cohort over a 14-year period, researchers found that for every additional hour of food jetlag, the risk of developing cardiovascular disease in men increases by 14%, while the risk of coronary heart disease increases by 21%. No significant difference was observed in women.

The study suggests that shifts in meal timing, often driven by work schedules that conflict with biological rhythms, may disrupt internal biological clocks and contribute to cardiovascular complications.
