The study found that drinking coffee with sugar is more refreshing. Can you believe it?

Are you a loyal consumer of coffee? Some people just like the bitter taste of coffee, but insist on drinking coffee without sugar in order not to get fat. However, a recent discovery by Spanish scientists may help you change your approach. They found that eating coffee and sugar at the same time was more productive than eating coffee alone or sugar alone. Coffee and sugar can promote each other, improving brain functions such as attention and memory of drinkers. So add some sugar to your coffee.
