Ditch the sugary pastries like Pop-Tarts. "Pop-Tarts are mostly refined carbohydrates, whether it's the multiple forms of added sugar or the refined flours. While low blood sugar may have driven you to the vending machine, this kind of quick blood sugar pick-me-up isn't worth the spike and crash," says Moon. A better pick? Dark chocolate bar, says Torchia.
"It's better to get a dark chocolate bar (no caramel) just dark chocolate, or dark chocolate with nuts as the dark chocolate has good antioxidant properties, which help with inflammation, and that bit of caffeine it has can also give you boost of brain focus without overpowering it with too much caffeine," she says.
