Moderate Coffee Drinking Associated With Lower Risk Of Death From Certain Conditions, Including T2D

Moderate Coffee Drinking Associated With Lower Risk Of Death From Certain Conditions, Including T2D


CBS News (11/16, Welch) reports on a study (http://circ.ahajournals.org/content/early/2015/11/10/CIRCULATIONAHA.115.017341.abstract) published in Circulation based on data covering “almost 168,000 women and over 40,000 men,” some of them for up to 30 years, finding that those who drank fewer that five cups of coffee daily “had a lower risk of deaths from cardiovascular disease, neurological diseases, type 2 diabetes [T2D] and suicide.”

NBC News (11/16, Fox) reports that the study found that those “who drink regular, moderate amounts of coffee are less likely to die from a range of diseases, from diabetes to heart disease.” It also found no additional benefit beyond five cups per day and that the benefit appeared whether the coffee was regular or decaffeinated. The study found that people who drank coffee regularly were also more likely to smoke. Coffee drinkers who did not smoke were “between 8 and 15 percent less likely to die,” than non-coffee drinkers. The study did not identify whether coffee drinkers added cream, milk, or sugar to their coffee. The authors suggested that antioxidants may play a role, but said that the chief finding is that coffee drinking is not harmful.

CNN (11/16, Storrs) reports the effect is clear only among those who drink coffee and “never smoked.” Among those, there was a 6% to 8% lower death rate connected to drinking up to 3 cups daily, and a 15% lower rate among those who drank 3 to 5 cups, and a 12% lower rate among those who drank over 5 cups daily. One possibility suggested is that coffee drinkers “drink less soda,” while it is also suggested that the lignans and chlorogenic acid in coffee “could reduce inflammation and help control blood sugar,” and so “reduce the risk of heart disease,” which was 10% lower among coffee drinkers. In addition, coffee drinkers had a 9% to 37% lower rate of death from “neurological diseases such as Parkinson’s and dementia.” They also had “between 20% and 36% lower rates of suicide.”

Reuters (11/16, Doyle) explains that the research did not allow for causal conclusions, but only associations among groups of people who drank varying amounts of coffee.

HealthDay (11/16, Norton) reports the study was funded by the National Institutes of Health. The data set came from surveys of “more than 200,000 US doctors, nurses and other health professionals” carried out over 30 years.
