Two to five coffees a day reduce the risk of premature death according to a new study coming from the Harvard T.H. Chan School of Public Health.
If you’re among the people who really enjoy their hot cup of coffee in the morning and wouldn’t give it up for anything, you’re in luck. Even if it is caffeinated or decaffeinated, coffee holds the same miraculous benefits on your health. Of course, moderation is key as too much coffee consumption may lead to sleep loss, high blood pressure, a little jittering.
Each individual reacts differently to coffee and the right amount of coffee differs greatly from person to person. However, according to the findings of the newly published study, featuring in the Circulation journal, two to five coffees a day reduce the risk of premature death.
The research team trying to unravel the benefits of coffee went beyond overall mortality and looked specifically at the association between coffee consumption and a lower risk of premature death from diabetes, neurological diseases, cardiovascular disease or suicide.
The study does not establish a cause-effect relationship, nor does it underline the process that makes coffee such an efficient deterrent of diabetes, cardiovascular disease or neurological diseases.
Ming Ding, one of the authors of the study and doctoral student with the Department of Nutrition stated that a possible explanation could be found with the bioactive compounds in coffee. These could efficiently reduce inflammation and insulin resistance. However, more studies should focus on these aspects as the newly published study only establishes the association between coffee consumption and lowering the risk of premature death.
The data analyzed for this study was retrieved from the Nurses’ Health Study 1 and 2, including 74,980 women and 93,054 women respectively. In addition, data on 40,557 men was retrieved from the Health Professionals Follow-up Study. Coffee consumption was assessed via questionnaires every four years during a 30-year timeframe.
Two to five coffees a day was overwhelmingly associated with a lower risk of dying from diabetes, cardiovascular disease or neurological diseases. Other factors that could influence the results were accounted for – smoking, BMI, alcohol consumption, exercising, diet.
Previous studies have pinpointed a wide array of health benefits stemming from moderate coffee consumption. The new study comes to confirm both these benefits and the 2015 Dietary Guidelines Advisory Report concluding that a healthy diet may include moderate coffee consumption.
We should be reminded however that not everyone metabolizes caffeine in the same manner. Thus, moderate coffee consumption is largely subjective and shouldn’t be treated as an indication for those who don’t drink coffee to start doing so.
