39. Pumpkin Seeds
Pumpkin seeds, or pepitas, are rich in so many necessary vitamins and minerals we need. In addition to a high tryptophan level, pumpkin seeds are high in magnesium and zinc, which can increase serotonin levels. Increasing your magnesium intake can help regulate your sleep cycle, promote healthy sleep patterns, and leave you feeling well rested when you wake up! Make sure to monitor how many seeds you eat; they are fatty and can be high in sodium.
