Caffeine is the most consumes drug in America, and probably in the entire world. In the United States, it is estimated between 85 and 90% of the people, consume some amount of caffeine daily, with the average being about being about 164 mg per day. Over the years caffeine has gone from being bad for you, to being good for you, back to being bad, and now it is considered good for you, again. There are many medical and food sites, that discuss the pro and cons of consuming caffeine. The general consensus is, that for the most part caffeine can help you, more than hurt you. It’s pretty common knowledge, that caffeine affects the brain, and it seems to allow you to concentrate better, and be more alert, about one hour after consumption. The common side affects, are keeping one awake at night, and it might give you some heart palpitations at higher doses. Anyone can go on line and find the information. However I did find some things that were interesting, and surprising, about how the scientific community feels about caffeine, and there is still a lot to learned.
One thing I found that has to with nothing, but is interesting, is caffeine supposedly was discovered by an Ethiopian goat herder, who gave it to his goats, and it seemed to give them more energy. Why you would want goats to have more energy is beyond me. The second new fact, for me anyway, was that there is not a lot of difference between what is safe to drink and what could cause some problems. Taking in about 150 to 300 mg of caffeine per day seems to be very safe. However taking in about 500 mg very quickly can cause some heart and blood pressure problems. So drink that coffee slowly. There is a debate in the scientific community, on whether caffeine is addictive. Some sites say that it definitely is, while other sites say that it does not have all the traits of what constitutes an addictive drug. All I know, is that some people do seem to have withdrawal symptoms from caffeine, if they try to stop taking caffeine abruptly. They can get the shakes, headaches, and will be come more agitated in certain situations. My most surprising finding was that it seems that we are all drinking coffee at the wrong time. It all goes back to that darn circadian rhythm, again. Its seems that when we wake up in the morning, that cortisol levels are at their highest, and therefore we do not need that jolt of caffeine, even though are brains may be telling us something different. It is best to hit the coffee machine about 10 am, when your cortisol is starting to go down, and your body really does need that boost. We seem to cycle back down around 1:30 so another cup will help again. It is best to end the caffeine intake just after 2PM if you want a good nights sleep.
There is no doubt that caffeine is a drug, and the affects of are real. On the whole caffeine can be a benefit, to help and maintain a healthy lifestyle. However, there are more dangers involved than the general media puts forth. After all, the coffee industry is a multi billion dollar business. It goes back to those idiosyncratic responses that so many people have to so many different substances. I know many people that say they can drink one or two cups of coffee at 7 to 8 PM, and sleep like a baby. If I drank one cup at 7 PM, I would be up all night. Caffeine has many health and wellness claims, some more substantiated than others. One claimed benefit is helping to prevent gall stones. The dose for prevention is 400 mg per day and even higher. I think I would take my chances with gall stones. I am going to start drinking my coffee later in the morning, when possible, and see if it makes any difference. It boils down to the same old thing. Please. just listen to your body, it will tell you all you need to know.
