Although there are reports that breakfast influences both mood and memory, there has been no attempt to consider whether a subsequent snack is beneficial. One hundred and fifty young female adults either fasted or consumed breakfasts of either 10 or 50 g of carbohydrate (corn flakes). Half received a further 25 g of carbohydrate in the form of corn flakes after 1 1/2 h (snack). Predictably, those who ate breakfast, and/or a snack, reported feeling less hungry. The larger the caloric intake, the less subjects reported hunger. Those who consumed a snack reported a better mood. Eating a larger breakfast was associated with poorer mood later in the morning, an effect reversed by eating a snack. Memory for the word lists was not influenced by eating breakfast, however, 20 but not 60 min after a midmorning snack, more words were recalled. Those who had eaten breakfast, as opposed to fasting, did, however, spend longer trying to recall the words. This finding was interpreted as evidence that eating breakfast was associated with better motivation. On a number of occasions, better memory was associated with lower blood glucose levels. These findings support previous observations that better glucose tolerance was associated with better memory.
