Reduces Brain Size Even in Moderate Amount
Recent research indicates that even moderate alcohol consumption can have adverse effects on brain health. Studies have found that consuming as little as one to two alcoholic drinks per day is associated with reductions in overall brain volume, including both gray and white matter. These structural changes are linked to cognitive impairments and accelerated brain aging. (penntoday.upenn.edu)
Additionally, moderate alcohol intake has been associated with increased iron accumulation in the brain, particularly in regions like the basal ganglia, which are involved in cognitive, emotional, and movement-related functions. Elevated iron levels in these areas correlate with poorer executive function, reduced fluid intelligence, and slower reaction times. (ndph.ox.ac.uk)
