A higher consumption of fruits and vegetables during the day is associated with a less fragmented sleep the following night, according to a study Led with young healthy adults.
An increase of 5 portions of fruits and vegetables per day is linked to an improvement of 16 % of the quality of sleep, objectively measured by activigraphy.
Methodology
- Participants were 34 young adults (average age: 28.3 ± 6.6 years, BMI: 24.1 ± 3.9 kg/m², 82.3 % of men, 50 % ethnic minorities) with a usual period of sleep between 7 and 9 hours per night.
- The food intake was evaluated using the automated food assessment tool over 24 hours (ASA24), with an average of 5.9 ± 1.6 days of paved data power supply to participant.
- The quality of sleep has been objectively measured by wrist activity, with the sleep fragmentation index as the main measure of the sleep disturbance.
- The researchers analyzed 201 Power-Food-Somme Data pairs after exclusion of 17 records for non-plausible food data.
Main results
- A higher consumption of fruits and vegetables during the day was significantly associated with a lower sleep fragmentation index (beta coefficient [CB]−0.60; standard error, 0.29; p = 0.038), indicating a less disturbed sleep.
- The higher carbohydrate intakes were also associated with less fragmented sleep (CB, −0.02; standard error, 0.007; p = 0.022), while added sugar had no significant impact (p = 0,54).
- A tendency to association between a higher consumption of red and transformed meats (p = 0.10) and a more disturbed sleep has been observed.
- Trends to associations between higher fiber contributions (p = 0.08) and in magnesium (p = 0.09) and a less disturbed sleep were also noted.
In practice
Previous observations based on the population had already highlighted the potential role of food as a modulator of the quality of sleep. But so far, clinical intervention studies have mainly focused on controlled laboratory conditions using extreme experimental diets. “” These results suggest that diets rich in complex carbohydrates, fruits and vegetables can promote better sleep health … an increase of 5 portions (from zero) of fruits and vegetables, responding to food recommendations, has been associated with an improvement of 16 % of sleep quality “, Specify the authors.
Main limitations
The main limitations include the relatively modest size of the sample and its predominantly male composition (82.3 %). The data was collected over relatively brief periods, which could limit the evaluation of long -term effects. In addition, participants initially reported good sleep quality and adequate sleep duration, which could have limited the ability to detect greater effects of sleep on sleep.
