The effect of a moderate level of white wine consumption on the hypothalamic–pituitary–adrenal axis before and after a meal Academic Article uri icon

abstract

  • The nutritional status of the individual at the time of alcohol consumption may mediate the rate of alcohol absorption and metabolism, thus influencing the systemic effect of alcohol on the body. The aim in the present investigation was to assess the effect of moderate white wine consumption on the hypothalamic-pituitary-adrenal (HPA) axis under variable nutritional conditions. Seven males aged between 19 and 22 years participated in all aspects of the current investigation. The experimental procedure for the fasting trial required participants to ingest either 4 standard units of alcohol (40 g) or the equivalent amount of placebo over a 135-min period before consuming food for 45 min. Alternatively, in the feeding trial, food was consumed for 45 min prior to participants ingesting either 4 standard units of alcohol (40 g) or the equivalent amount of placebo over a 135-min period. Blood alcohol, salivary cortisol, and salivary dehydroepiandrosterone sulfate (DHEAS) levels were assessed at 45-min intervals during the 180-min experimental periods. The results demonstrated a significant alcohol-induced decrease in salivary cortisol irrespective of nutritional status and a significant decrease in salivary DHEAS when alcohol is consumed alone under fasting conditions only. It was concluded that moderate white wine consumption may promote a transient alteration in the functioning of the HPA axis.
