问题 　　People who usually chow down on chilli peppers may live for longer and have a significantly reduced risk of dying from cardiovascular disease or cancer, research suggests.
　　Previous studies have found that capsaicin, the【C1】________that gives chilli peppers their【C2】________kick, can have anti-inflammatory, antioxidant and anti-cancer effects when eaten.
　　To further investigate the effects of【C3】________chilli peppers, the researchers gathered together the health and dietary【C4】________of more than 570,000 patients in the US, Italy, China and Iran.
　　They found that those who ate chilli peppers【C5】________had a 26 percent reduction in cardiovascular disease mortality, a 23 percent relative reduction in cancer mortality, and a 25 percent relative reduction in all-cause mortality,【C6】________those who rarely or never ate them.
　　" We were surprised to find that frequent consumption of chilli pepper was【C7】________an overall risk-reduction of all-cause, CVD and cancer mortality. It highlights that dietary factors may play an important role【C8】________overall health," said senior author Dr. Bo Xu, a cardiologist at Cleveland Clinic’s Heart Institute.
　　" The exact reasons and【C9】________that might explain our findings, though, are currently unknown," he added.【C10】________, it is impossible to【C11】________     say that eating more chilli pepper can【C12】________life and reduce deaths. More research, especially evidence from【C13】________controlled studies, is needed to【C14】________these preliminary findings. "
　　Additionally,【C15】________the precise【C16】________and type of chilli pepper consumed varied across the four studies used in the research, it’s【C17】________to determine exactly how much and what type of chilli peppers may provide the health【C18】________.【C19】________, the researchers are continuing to analyse the data【C20】________uncovering more concrete evidence.
