When you are having a mood swing, eating a chocolate bar is not the best solution. Sure, it will elevate your blood sugar in the short term, but refined sugars are only setting you up for a crash later on. There are ways to stabilize your blood sugar to avoid mood swings that are healthier and more effective. Fueling your body with healthy food not only reduces mood swings, it also helps you to perform at your peak mentally so you can knock it out of the park.
