I enjoy coffee every morning. Well, it's more than that; not only do I enjoy it, I require it every morning. A morning without coffee basically adds up to a wasted day. If I don't get my morning fix, I'm spacey and slow for the duration. Coffee after the fact does not solve this problem. I need coffee in the morning to function.
But, I digress. Coffee amounts to billions upon billions of dollars in trade each year. It's safe to say that it's one of the most important crops and commodities in the world. Coffee's most important ingredient and its purpose for existence, caffeine, is a drug. It affects the mind and body, and those effects happen to be, for the most part, positive. (See above paragraph). That said, coffee's influence on society is eerily similar to that of tobacco say, 80 years ago. It seems that every month or so, some new "study" is cited by the major news outlets which describes the health benefits of drinking coffee. These studies postulate that, despite the fact that caffeine is a mind-altering drug, its consumption isn't merely harmless -- it's beneficial. And that the consumption of coffee has side-benefits such as lowering blood pressure, etc.
Again, cigarettes were promoted in the same manner in the 50's. Hell, doctors were featured in ads and were known to prescribe them. My point is this: It wouldn't surprise me at all if in, say, 30 years, coffee was found to be seriously detrimental to our health. Perhaps it could be identified as a cause of Alzheimer's disease or some other nefarious unexplained illness. I know that this postulation sounds the kind of speculation that some conspiracy-minded luddite would spew on a talk "news" show. All I'm going on is a hunch and recognition that things which appear to be harmless to us now can often be wolves in sheep's clothing as medical technology advances. And, quite honestly, the fact that I'm addicted to a drug and depend on it for my day-to-day existence certainly feels wrong.
Will this cause me to quit drinking coffee? Hardly. But, when it's uncovered in 2040 that Starbucks has been fabricating health benefits and hiding the deleterious effects on a drinker's well-being (especially over the course of a lifetime), don't blame me. Instead, join me in the inevitable class action suit filed against Big Coffee.
