在最近的一项研究中，研究了多喝咖啡和过长寿之间的相似关系。这项研究也发表在同一期刊上，这项研究将实验人口简化为非白人美国人。这项研究包括了1 85000人的巨大目标人群，他们进行了实验，并发现了结果。人口包括美国原住民、非裔美国人、日裔美国人、夏威夷人以及拉丁美洲人。有趣的是，这项研究表明，这项研究的结果与之前的相似。事实上，喝更多的咖啡确实会增加预期寿命，这也是这项研究的结果。当两项如此大规模的研究表明相同的结果时，很难忽略它们。从这些研究中得出的另一个有趣的结论是，咖啡对不同出身和种族的人的预期寿命的影响是相同的。因此，咖啡的作用深入到人体的生物系统中，并不局限于不同的基因或区域的影响。它影响人体的基本生物组成，因此对世界上不同地区的人产生同样的影响。在这些研究中也研究了适量的咖啡摄入量。研究结果表明，每天喝2 – 4杯咖啡会比不喝咖啡的人减少18%的死亡风险(Freedman et al .，2012)。

尽管这些研究有充分的理由相信喝更多的咖啡会导致更高的预期寿命，但也有不同的研究表明。此外，在这些研究中还没有考虑到许多因素，这些因素在证明饮用更多的咖啡会导致更高的预期寿命时必须考虑。例如，咖啡饮用者比不喝咖啡的人更富有或更健康的因素还没有考虑。这两个因素非常重要，对预测个人的寿命有重大影响。此外，咖啡中的成分导致预期寿命的提高也尚未被发现。研究人员认为，咖啡中咖啡因的含量并不会导致预期寿命的增加，因为咖啡在实验过程中饮用咖啡的人的寿命也会延长。因此，没有科学证据表明在咖啡中发现的物质会导致预期寿命的提高，直到发现这种物质，研究结果将一直是有争议的(约翰逊等人，1992年)。

There was another study conducted in the recent past to study a similar correlation between drinking more coffee and leading a longer life. This study was also published in the same journal as above and this study streamlined the experiment population to non-white Americans. The study included a huge target population of 1,85,000 people on which experiments were conducted and results were noted. The population included a wide range of Native Americans, African-Americans, Japanese-Americans, Hawaiians, and Latinos. What is interesting to note from the study is that the result from this study is similar to the earlier one. Drinking more coffee, indeed, does result in increasing life expectancy, as per the result of this study as well. When two such vast scale studies suggest the same results, it is hard to ignore them. Another interesting conclusion from these studies is that the effect of coffee in increasing life expectancy is the same for people from different origins and ethnicity. Thus, the effect of coffee is deep into the biological system of the human body and is not limited to different genes or regional influences. It effects the basic biological composition of the body and hence its effect is the same on people from different parts of the world. The right amount of coffee intake was also studied in these studies. The results suggest that consuming 2-4 cups of coffee daily will lead to a decrease in the risk of death by as much as eighteen percent than those who do not consume coffee (Freedman et al., 2012).

Although these studies have a good reason to believe the fact that drinking more coffee leads to a higher life expectancy, however, there are various studies that suggest otherwise as well. Besides, there are many factors that have not been considered in these studies which are essential to consider when proving that drinking more coffee leads to a higher life expectancy. For instance, factors such as coffee drinkers who are wealthier or healthier than non-coffee drinkers have not been considered. These two factors are extremely essential and have a significant impact on predicting the life span of an individual. In addition, the components present in coffee which lead to higher life expectancy have also not been discovered yet. Researchers suggest that it is not the caffeine present in coffee which leads to higher life expectancy because the positive results of coffee increasing life expectancy was also exhibited by people in the study who has decaf coffee during the experiments. Thus, there is no scientific evidence of the substance found in coffee that leads to higher life expectancy and until that substance is discovered, the study results will always be debatable (Johansson et al., 1992).
