Overview

• Participants who consumed at least five cups of fruits and vegetables experienced a 16 per cent improvement in sleep quality within 24 hours compared to those who ate none.
• Researchers tracked 34 healthy adults using a food-logging app and wrist-worn sleep monitors to correlate daily diet with sleep fragmentation and overall rest.
• The boost in rest is attributed to fibre-rich produce fostering beneficial gut bacteria that regulate neurotransmitters such as serotonin and melatonin.
• Higher intake of whole grains also correlated with better sleep, while increased red and processed meat consumption was linked to more disrupted nights.
• Despite NHS advice to eat five portions of fruit and vegetables daily, only a fraction of adults meet the target as rising produce prices raise concerns about access and adherence.
