38. Edamame
Edamame beans, or soy beans, are high in isoflavones, which increase serotonin production. Consuming two or more servings of soy per day can improve the quality of your sleep. Try cooking them up with garlic and pepper, or snack on them with a small sprinkle of salt (but do not overdo it!). They are rich in fiber and protein too, so they are filling and should quiet the growling in your stomach when you need a snack.
