Numerous studies have been conducted globally about coffee over the years. Most recently, findings have pointed to coffee drinking being linked to lowering the risk for many health conditions. The long list includes depression, suicide, Parkinson’s disease, melanoma, Type 2 diabetes, and prostate cancer.
All of this comes as a far cry from what used to be said about coffee being a health risk. In fact, it was seen as a possible carcinogen by the World Health Organization in 1991. Now-discredited studies show it was actually smoking (typically hand-in-hand with coffee) that held responsibility for the risk.
Coffee is well-loved all over the world. When the coronavirus pandemic hit, coffee shops with pick-up/take out options and many home brews were one of the few areas to thrive. Aside from the popular chains, local brands thrived as well, from ready-made drinks to a variety of beans.
Amongst the many studies over time, the average finding is that 4 to 5 cups of coffee in eight-ounce cups (equal to around 400 mg of caffeine) daily is linked to lower death rates. A particular study that went on over a 30-year span that comprised over 200,000 participants supports this quite strongly.
Respondents who drank three to five cups of coffee daily (caffeinated and decaffeinated alike) had a 15% less likelihood of dying early from all causes.
The same study also saw a 50% suicide risk reduction among coffee drinkers. This is likely due to a boost in brain chemicals with effects that are antidepressant. A research team at the Harvard School of Public Health recently published a report that found coffee drinking in moderation could play a role in a healthy lifestyle.
