Abstract:
Alcohol consumption and the glycemic load (GL) of a meal interact to influence both mood and memory. The authors compared the effects of eating a high GL lunch on mood and memory after consumption of a breakfast high in either rapidly (RAG) or slowly (SAG) available glucose. When less than 4.5 g of alcohol had been drunk the previous evening, the eating of a high RAG meal was associated with better memory later in the morning. In contrast, after more than 4.5 g of alcohol had been drunk the previous evening, the SAG meal resulted in better memory. After lunch, if more than 4.5 g alcohol had been drunk the previous evening, the RAG breakfast, but neither the SAG meal nor fasting, resulted in a more confused feeling.
