A nutritionist has suggested that consuming a spoonful of peanut butter before bedtime may help improve sleep quality, citing its potential role in stabilising blood sugar levels and supporting the body’s natural sleep-related biochemical processes. In a recent social media video, nutritionist Deepsikha Jain explained that irregular sleep patterns and frequent night awakenings are often linked to lifestyle factors, including fluctuations in blood sugar levels.

She suggested that small dietary adjustments before bedtime may help some individuals achieve more stable and restful sleep, rather than immediately turning to sleep medications. Jain recommended peanut butter as a simple pre-sleep snack, arguing that its combination of nutrients may contribute to improved sleep quality. She noted that its healthy fat content may help slow down glucose absorption, potentially reducing sudden drops in blood sugar during the night that some people associate with disturbed sleep cycles.

She also highlighted the presence of tryptophan in peanut butter, an amino acid that plays a role in the production of serotonin, a neurotransmitter linked to mood regulation and sleep onset. According to her, this pathway may support relaxation and make it easier for some individuals to fall asleep naturally when consumed in moderation before bedtime.

In addition, she pointed to magnesium as another key nutrient found in peanut butter, which is often associated with muscle relaxation and nervous system regulation. Magnesium is widely studied for its potential role in supporting sleep quality, particularly in individuals with dietary deficiencies, though effects may vary depending on overall nutrition and health status.

However, experts generally note that while foods containing tryptophan and magnesium may support sleep in certain cases, they are not a universal solution for insomnia or chronic sleep disorders. Sleep quality is influenced by multiple factors including stress, environment, and routine, and dietary changes are typically most effective when combined with broader lifestyle adjustments such as consistent sleep schedules and reduced screen exposure before bedtime.
