Nutritionist Leyla Muedin delves into the reconsideration of alcohol consumption during the holiday season. With increasing awareness of the effects of alcohol on sleep and overall health, Leyla discusses a study from the European Heart Journal that links excessive alcohol intake to heart arrhythmias, using data from the Munich Beer Related Electrocardiogram Workup Study (MunichBREW). The episode explores the broader cardiovascular impacts of alcohol, such as elevated heart rate, atrial fibrillation, and high blood pressure. By highlighting that alcohol is a mitochondrial poison and neurotoxin, the discussion extends to its role in causing weight gain, liver disease, certain cancers, and mood disorders. Leyla encourages listeners to reevaluate their drinking habits and consider alternatives like alcohol-free beverages to achieve better health outcomes during a season known for indulgence.
