5. Soda
Many a person swears they can’t go a day without their Coke or Pepsi. While you may love the fizzy sweetness, what you’re most likely craving is the caffeine hit. One serving of Coke provides 30 mg of caffeine—enough to give you a nice wake-up jolt but not enough to make you jittery.
A less common reason for soda cravings is a calcium deficiency. The phosphoric acid in carbonated drinks can leach calcium and magnesium from your bones, creating a vicious cycle of depletion and craving.
