German chemist, Friedlieb Ferdinand Runge, first identified caffeine in 1820. It has been estimated that over 120,000 tons of caffeine are consumed globally each year. The most common way of caffeine intake, as many of us know, is coffee. Even though a cup of coffee can really provide that extra “pick-me-up” in the morning, too much caffeine can have very severe and harmful effects on the human body. Certain energy drinks offer large amounts of caffeine in a single serving, which is dangerous for people who consume multiple servings. Another issue with caffeine is the fact that our bodies grow accustomed to it. Some people who have caffeine everyday find that, after a while, coffee or other forms of caffeine do not really help to “wake them up.” The only way to fix this issue is to consume more caffeine, which again, is not always good for the body. Not to mention, coffee can be expensive. In 2011, the average national price for a cup of coffee was $1.38, a figure that has undoubtedly increased since then. And at certain coffee places, a cup of coffee can cost close to $5.
