49. Tofu
While this may not necessarily be a common staple in your fridge, tofu is packed with high-quality protein, calcium, and phytoestrogen. Tofu is also a source of tryptophan a.k.a. “the body clock hormone,” which is an amino acid that increases your serotonin and ultimately, leads to a better night’s sleep. Studies show that a 1 gram increase in tryptophan can produce a significant increase in sleepiness and a decrease in time it takes to fall asleep. 1 gram may seem like nothing, but it’s equivalent to about 12 ounces of poultry – definitely not a small nighttime snack!
