The health effects of coffee has been a highly debated topic since its inception. However, only recently, a new study has emerged, suggesting that the all-time favorite could be in fact a plus for good health.
The high profile study, involving 200000 women and 50000 men, indicates that drinking coffee actually decreases your risk of mortality. Among non-smoking participants, those who drank less than one cup to three cups of coffee a day had 6-8% lower risk of dying than non-drinkers. In addition, those who consume three to five cups had 12-15% lower death rates.
According to Ming Ding, a doctoral student in the Harvard School of Public Health, and the lead author of the study, these findings are consistent with his hypothesis that coffee consumption is associated with lower risk of type 2 diabetes and heart disease.
Although it is possible that the dietary habits of coffee drinkers contributes to the lower risk of death, the researchers are said to have taken that into account. According to Ming Ding, chemicals in coffee such as lignans and chlorogenic acid can help reduce inflammation and control blood sugar. In addition, coffee drinkers had up to 36% lower suicidal rates.
Still, Ming Ding was unsure if people who drink a lot of coffee have better lifestyle habits that lead to lower deaths, hence the study might be inconclusive. Also, there may not have been sufficient deaths from a specific types of cancer to see a difference.
