【简答题】

We’ve all had a bad feeling soon after a hearty lunch.You can’t stay focused , your energy level falls , and you wish you possessed a warm blanket so you could curl up under your desk for a quick nap.But you have important things to do—like completing that project or leading a team meeting in less than an hour. You don’t have to suffer that _ fate anymore.I have four foods that will get your focus back on track so that you can finish your workday stronger than you started.Keep these products handy in your office , and you’ll never suffer from that 2 pm mental slog ever again. Green Tea While coffee is an important afternoon pick­me­up , green tea should not be overlooked.The unique combination of the amino acid thiamine ( 硫胺素 ) and caffeine has been shown across several studies to improve creativity , ability to multitask , and reaction time.Try some amazing tea recipes to get started. Almonds Almonds are a great afternoon recharger and research from Purdue University shows they will also aid in your weight­loss efforts.This is because almonds provide sustained energy : a mix of fat , fiber , and protein.Those elements allow almonds to offer a convenient snack that gives you a smooth shot of energy that comes from controlling your blood sugar levels.Plus , research shows that people who regularly eat nuts have as much as a 50 percent reduced risk of having a heart attack. Greek Yogurt Research from the University of Missouri shows that protein helps your body into better blood sugar control by stimulating the release of the hormone glucagon ( 胰高血糖素 ) . Aim for a cup that has 20 to 23 grams of protein for your snack. Dark Chocolate Despite often being viewed as a bad dietary food , dark chocolate can help fight off that urge to take a nap in the middle of the day.While dark chocolate does contain small amounts of caffeine , its real power comes from phenethylamine ( 苯乙胺 ) . Research from Middle University in London shows that just smelling chocolate can shift brain activity towards greater attention. 1 .
