What to watch with MY FOODBOOK and sleep?

When combining MyFoodbook with sleep tracking, watch for: 1) Meal timing – late heavy meals can disrupt sleep. 2) Nutrients – magnesium, tryptophan, and dietary melatonin may support sleep. 3) Caffeine and alcohol – both impair sleep quality even when consumed earlier. 4) Blood sugar stability – glycemic variability can affect sleep architecture. Evidence is mostly observational; no strong RCTs support personalized diet-sleep recommendations from food diaries alone. Keep a sleep log and food diary to identify patterns. Safety note: Do not make drastic dietary changes without professional guidance, especially if you have medical conditions.
