The foods you crave, and when you crave them, might just depend on your mood. "Our bodies are designed to fulfill our needs," Dr. Oz says. "The gut and the brain are the two most closely related organs. So it makes perfect sense that the foods we eat change the way our brains function."
And the intersection of food and mood doesn't stop at cravings. It also involves how we can proactively affect our emotions. "If you're depressed, you should take omega-3 fatty acids, especially women who are having babies," Dr. Oz says. "That baby sucks all that healthy fat out of your body and you get depressed after you have this beautiful, brilliant wonderful baby."
