“…Some found reduced SOL with the consumption of a higher carbohydrate diet (22,23) but others reported a trend for greater SE after an acute intake of a very LC meal (24). The findings from these studies support the idea that dietary carbohydrate intake or pre-bedtime meal also influence sleep architecture, particularly REM and SWS.…”

“…There is a substantial body of evidence to indicate a role of carbohydrate intake on sleep indexes ( Table 1). Both high-carbohydrate (HC) and low-carbohydrate (LC) diets are associated with changes in sleep architecture (20)(21)(22)(23)(24)(25). Carbohydrate manipulation has primarily been shown to affect REM sleep and SWS; however, non-REM (NREM) sleep, SOL, and REM-onset latency have also been affected.…”

“…The glycemic index (GI) of carbohydrates has also been studied as a dietary factor related to sleep architecture. Afaghi et al (23) investigated the effects of both GI and meal timing on sleep architecture in men. Sleep was measured on 3 separate test nights, which differed in the glycemic index of the pre-bedtime meal: either a low-GI (GI = 50) or a high-GI (GI = 109) meal was consumed 4 h before bedtime or a high-GI meal was consumed 1 h before bedtime.…”

There is much emerging information surrounding the impact of sleep duration and quality on food choice and consumption in both children and adults. However, less attention has been paid to the effects of dietary patterns and specific foods on nighttime sleep. Early studies have shown that certain dietary patterns may affect not only daytime alertness but also nighttime sleep. In this review, we surveyed the literature to describe the role of food consumption on sleep. Research has focused on the effects of mixed meal patterns, such as high-carbohydrate plus lowfat or low-carbohydrate diets, over the short term on sleep. Such studies highlight a potential effect of macronutrient intakes on sleep variables, particularly alterations in slow wave sleep and rapid eye movement sleep with changes in carbohydrate and fat intakes. Other studies instead examined the intake of specific foods, consumed at a fixed time relative to sleep, on sleep architecture and quality. Those foods, specifically milk, fatty fish, tart cherry juice, and kiwifruit, are reviewed here. Studies provide some evidence for a role of certain dietary patterns and foods in the promotion of high-quality sleep, but more studies are necessary to confirm those preliminary findings.

“…Some studies indicate an impairment of sleep quality when there is an excessive carbohydrate intake. 17,18 Driver et al, 19 however, comparing the effect of an evening meal on nocturnal sleep in seven healthy men, did not fi nd any effect. Therefore, this study proposes to analyze the correlation between habitual food intake and sleep patterns in healthy individuals.…”

Study Objectives: The purpose of this study was to analyze the relationship between food intake and sleep patterns in healthy individuals. Methods: Fifty-two healthy volunteers (27 women and 25 men) were recruited to participate in the study. Volunteers underwent sleep evaluation through nocturnal polysomnography and completed a 3-day food diary to evaluate food intake. Results S C I E N T I F I C I N V E S T I G A T I O N SO besity is becoming a worldwide epidemic. 1 The etiology of this disease is multifactorial; among the causes are changes in food intake, 2 life style, environment, 2,3 and genetics, 4,5 in addition to physiological 6 and psychological 7 infl uences and, more recently, alterations in sleep patterns. [8][9][10][11] Sleep curtailment has become common due to the demands and opportunities of modern society.12 Recent studies show that alterations in sleep time can infl uence various aspects associated with the nutritional and metabolic balance of the body, such as the control of body mass, 9,11 food intake, 10,13 glycemic levels, 14,15 and the levels of cholesterol and triacylglycerol. 16 Although some studies show that short duration sleep changes the food intake pattern and may cause obesity, 9-11 few studies have analyzed whether the opposite casual sequence also occurs; that is, if food intake promotes alterations in the sleep pattern. Indeed, studies that have examined this matter are controversial and use different methodologies. Some studies indicate an impairment of sleep quality when there is an excessive carbohydrate intake. 17,18 Driver et al.,19 however, comparing the effect of an evening meal on nocturnal sleep in seven healthy men, did not fi nd any effect. Therefore, this study proposes to analyze the correlation between habitual food intake and sleep patterns in healthy individuals. METHODS SampleFifty-two healthy volunteers (27 women and 25 men) between 19 and 45 years old took part in this study. The participants were young adults and were non-obese. They were sedentary and not taking medication. They were all nonsmokers and spent regular times in bed at night (7.5-8.5 h). The subjects did not suffer from sleep disturbances (apnea and hypopnea index [AHI] < 5, and periodic leg movements [PLM] during sleep were < 5, as assessed bRIEF SUMMARY Current Knowledge/Study Rationale: Few studies have analyzed if food intake promotes alterations in the sleep pattern. Therefore, the objective of this study was to analyze the correlation between habitual food intake and sleep patterns in healthy individuals. Study Impact: This study demonstrated that a higher food intake close to the sleeping period is associated with negative aspects of sleep patterns in healthy individuals, especially in women. However, this is an area poorly explored in the literature, and more studies are necessary to elucidate the real infl uence of food intake upon sleep.

“…It is particularly plentiful in chocolate, oats, dried dates, milk, yogurt, cottage cheese, red meat, eggs, fish, poultry, sesame, chickpeas, almonds, sunflower seeds, pumpkin seeds, spirulina, bananas, and peanuts. It has been demonstrated in both animal and human tests that ingestion of a meal rich in carbohydrates triggers release of insulin [13]. Insulin in turn stimulates the uptake of large neutral branched-chain amino acids (BCAA), but not tryptophan into muscle, increasing the ratio of tryptophan to BCAA in the blood stream.…”
