Dr. Rob van Dam, Assistant Professor in the Department of Nutrition, Harvard School of Public Health suggests that coffee may have some beneficial health effects after all...Research over the past few years suggests that coffee consumption may protect against type 2 diabetes, Parkinson’s disease, liver cancer, and liver cirrhosis. And the latest study on coffee and mortality found that people who regularly drank coffee actually had a somewhat lower risk of death from cardiovascular disease than those who rarely drank coffee; this result needs to be confirmed in further studies, however. So looks like the latest Harvard study on coffee and health seems to offer good news for coffee drinkers.

 

We looked at the relationship between coffee consumption and overall mortality in the Nurses’ Health Study and the Health Professionals Follow-Up Study, which together included about 130,000 study volunteers. (1) At the start of the study, these healthy men and women were in their 40s and 50s. We followed them for 18 to 24 years, to see who died during that period, and to track their diet and lifestyle habits, including coffee consumption. We did not find any relationship between coffee consumption and increased risk of death from any cause, death from cancer, or death from cardiovascular disease. Even people who drank up to six cups of coffee per day were at no higher risk of death. This finding fits into the research picture that has been emerging over the past few years. For the general population, the evidence suggests that coffee drinking doesn't have any serious detrimental health effects.

It’s an important message because people have seen coffee drinking as an unhealthy habit, along the lines of smoking and excessive drinking, and they may make a lot of effort to reduce their coffee consumption or quit drinking it altogether, even if they really enjoy it. Our findings suggest that if you want to improve your health, it’s better to focus on other lifestyle factors, such as increasing your physical activity, quitting smoking, or eating more whole grains.
