There is some evidence to suggest that eating slowrelease energy foods, or low glycaemic index foods, (foods that keep blood sugar levels stable), may improve general health and sleep quality (as well as helping the individual to lose fat). The idea is that the lower the glycaemic rating of a particular food, the more slowly energy, in the form of glucose, will be released into the body (see Low glycaemic index foods, opposite). Thus glucose and insulin levels are prevented from plummeting during the night, which may be beneficial for sleep. Foods such as turkey and dairy products may also be helpful, as they are high in tryptophan – the amino acid that the body uses to produce the sleep-inducing hormones serotonin and melatonin (see pages 16-17).
