A common therapeutic approach for alleviating insomnia is maintaining sleep hygiene, a part of which involves diet. Sleep hygiene techniques include not eating too much at night and not eating too late into the night. It also includes avoiding or limiting the intake of alcohol, caffeine, and caffeine-containing foods and drinks (e.g., coffee, tea, and chocolate), especially when it is close to bedtime. Following a healthy, nutrient-rich diet (e.g., high in fruits and vegetables, low in refined sugar) is also considered a part of maintaining good sleep hygiene.[1][2][3]
