D

    What can be both red or green, round or sharp, big or small, and more importantly, loved or hated by someone? Yes, the answer is chilies (辣椒).

    Many of us in China enjoy adding chilies to our food, but did you know that this spicy (辣 的)   vegetable could also be dangerous? A 34-year-old US man recently ended up in hospital after eating a Carolina Reaper, the spiciest chili people have known so far. After taking just a single bite of one, the man suffered from serious headaches in the following days, reported BBC News.

    In fact, eating spicy food causes stomachache and headache. But if chilies are harmful, why do people like to eat this vegetable? So what makes people love chilies so much? The human body is influenced by natural chemicals that produce “a sense of happiness”, noted BBC News.

    And chilies do good to people in another way. Scientists found that the death rate of those who eat spicy food once or twice a week is 10 percent lower than those who eat it less than once a week. The death rate is 14 percent lower for those who eat spicy food six to seven times a week. This encourages people to eat more spicy food to improve health and bring less death risk at an early age. So, don't worry if you love spicy food. It seems that chilies are actually good for us.
