3.Spinach
If this one leaves a bad taste in your mouth, almost any leafy green will do — kale, collard greens, or Swiss chard. The key is the magnesium, which may help you feel calmer. Make sure you get enough of that mineral to help keep things in check.
4.Oatmeal
This is a complex carb — it gets into your system slowly and gives you a steady flow of energy that can help keep you on an even keel. It also can give you a boost of a brain chemical called serotonin that can lift your mood.
