It’s not lunch yet, but you want to keep your energy level revved up, so while it’s okay to take your usual cup of coffee, here’s a healthier alternative: green tea. It’s packed with antioxidants — in particular epigallocatechin gallate or EGCG, which is known to be helpful in boosting learning and improving one’s memory.
If you’re having some pre-lunch hunger pangs, curb them with a handful of nuts, such as pistachios. They’re made up of healthy fats and fiber to help you stay alert without filling you up too much to want to skip lunch. Other options are berries with string cheese, low-fat Greek yogurt, and whole-wheat toast with avocado.
