题目

阅读下列短文, 从每题所给的A、B、C、D四个选项中选出最佳选项。 Eating spicy foods frequently may be tied to a slightly lower risk of an earlier death, according to a new study. However, more research is needed to confirm the link, experts say. The researchers found that the people in the study who ate spicy foods one or two days a week were 10 percent less likely to die during the study, compared with those who ate spicy foods less than once a week, according to the study published in the journal The BMJ. Moreover, the people in the study who ate spicy foods three or more days a week were 14 percent less likely to die during the study, compared with those who ate spicy foods less than once a week. However, the study was observational, and so it is too early to tell whether there is a certain relationship between eating spicy foods and lower mortality, _said study author Lu Qi, an associate professor at Harvard School of Public Health in Boston, Massachusetts. "We definitely need more data from other populations, " Qi told Live Science. "The researchers don't know why exactly the consumption of spicy foods may be linked to the drop of early death, but previous research on cells and animals has suggested several possible connections, " Qi said. "It is unclear whether the observed associations are the direct result of spicy foods intake, or whether spicy foods are simply a marker for other beneficial but unmeasured dietary components(成分), " said Nita Forouhi, a nutritional expert. At this point, researchers don't know for sure whether eating spicy foods can have a beneficial effect on human health and mortality, Forouhi wrote. "Future research is needed to make sure whether spicy food consumption has the potential to improve health and reduce mortality directly, or if it is merely a marker of other dietary and lifestyle factors, " she said. （1） Which section of a newspaper is the article probably taken from?
