The Science
Beets provide magnesium and potassium, which can support muscle relaxation and nerve function, potentially aiding sleep quality. However, they also contain 14% DV of sugar per 100g, which may cause blood sugar spikes that could disrupt sleep if eaten close to bedtime. The fiber and folate are beneficial but do not directly address sleep onset or maintenance.
Recommendation
Consume beets earlier in the day or in moderate portions to avoid sugar-related sleep disruption, and pair with a protein or fat source to stabilize blood sugar.
