The Truth About Caffeine
How many of you here consider yourself caffeine addicts? How much coffee do you drink in a day? One cup? Two cups? More? How about caffeinated sodas?
Caffeine is pervasive in our society these days and every few months we hear about how a study has shown that it is bad for us or good for us. What are we to believe?
Today, I'd like to give you some of the facts about caffeine and its effects on your body. I may not cause you to change your coffee consumption, but at least you'll be better informed about what you are putting into your body.
Specific purpose: To inform my audience about the effects and health issues of caffeine.
I'm going to talk about the beneficial effects of caffeine, the negative effects and discuss what are considered to be 'safe' levels of caffeine consumption.
Let's start with the good news. Caffeine, which comes from the leaves, seeds and fruits of about 63 different plants, is well known as a stimulant.
It is clear from the information above that caffeine taken consistently can have very dangerous effects. So why is caffeine taken so often? For one, food and drug manufacturers aren’t required to list the amounts of caffeine on their products
, so parents nor adults know what they’re consuming. Caffeine is present in many medications such as
cold combinations, analgesics, and stimulants. Kolephrin, a type of cold combination, has twice the amount of caffeine and is almost equal to the amount of caffeine in instant coffee. In beverages, large amounts of caffeine are present in Black tea, Green tea, Mountain dew, Coca-Cola, Pepsi, Java Water, etc. It is important to note
, that some of the caffeine from the drinks above is natural such as that from Coca-Cola. However, some beverage companies such as Mountain Dew add caffeine so that it becomes slightly addictive
. Children who consume soda on a daily basis often suffer from withdrawal effects because of the lack of caffeine. For these reasons, it is essential the food and drug manufacturers list the amounts of caffeine in their products
That's why people drink it, right?
Caffeine does help you wake up and feel more alert and it has been shown to increase attention spans. This is a beneficial effect for people who are driving long distances and for people who are doing tedious work.
As one can see, the negative effects of caffeine greatly outweigh the positive effects. So why is caffeine so appealing to people? Nutritionists believe that caffeine does not pose a risk to kids and teens when taken in moderation. Adults desire the caffeine because it improves mood
, mental performance, and physical performance. However, if caffeine is consumed in great amounts over short periods of time, it can cause withdrawal effects such as headaches and lead to caffeine dependency, hypertension, ulcers, etc. Because of this, it is necessary for food and drug companies to label the
amounts of caffeine. One can conclude that caffeine when taken in moderation can have pleasing effects on the central nervous system which most
people clearly desire.
Calling this a health benefit may be stretching it, though staying awake while you are driving a car definitely contributes to your well-being!
Caffeine also contains antioxidants, which have been shown to have cancer prevention qualities.
The negative effects of caffeine are largely dependent on how much you consume.
When consumed in small quantities - for example, when you have one cup of coffee or one soda - caffeine can increase your heart rate, cause you to urinate more (which can cause dehydration) and prompt your digestive system to produce more acid.
In larger amounts, caffeine can cause you to have headaches, feel restless and nervous, be unable to sleep, and even - in very large quantities - to have hallucinations. (Don't try that at home!)
When larger amounts of caffeine (over 600 mg per day) are ingested over long periods of time, they can cause sleep problems, depression and digestion issues.
According to a Medline article on the National Institutes of Health website, having caffeine in your diet is not of any benefit to your health, but by the same token moderate consumption is not considered harmful.
They say that having up to 3 eight ounce cups of coffee a day - or 250 mg of caffeine - is considered (quote) "average or moderate". 10 cups of coffee a day is considered excessive. Also, remember that the amount of caffeine per cup can vary greatly depending on the type of beans that are used and the strength of the brew.
Caffeine, above all, should not be mixed with other drugs because caffeine can increase the stimulant effects of other drugs such as appetite suppressants and tranquilizers. Interaction of caffeine with birth control pills or Verapamil can limit the body’s ability to eliminate caffeine causing insomnia and palpitations or rapid heart beats. Hypertension, or high blood pressure, can be another dangerous effect
caused by caffeine when consumed at great amounts. Caffeine can also pose a risk to women because it decreases their chances of getting pregnant and increases the chance of miscarriage. Increased amounts of caffeine consumption can over
stimulate the fetus causing abnormal heart beats before and after birth
. Caffeine, in as little as 2 cups of coffee in postmenopausal women, can cause a great amount of bone loss. Ulcers are also a side effect of caffeine intake because caffeine stimulates secretion of gastric acid causing irritated stomach ulcers and heartburn. Because of the harmful effects of caffeine, it is essential that it be taken in moderation.
Most sodas with caffeine, unless they are specially enhanced, have about 35 mg of caffeine per 8 ounces. This means that you don't have to worry TOO much unless you are drinking several 2 liter bottles per day.

Also, the effect of caffeine on you personally will depend on a number of factors, such as your weight, general health, mood and personal sensitivity to caffeine.
As you can see, caffeine can have both positive and negative effects on our health and well-being. Nevertheless, the bottom line is that if you drink your coffee or sodas in moderation, you don't have to worry too much.
Although caffeine has many positive effects, it also poses many negative effects. After about 3 cups of coffee, your body becomes dependent on caffeine. To demonstrate this, a study was done on a group of volunteers who drank 1-3 cups of coffee who soon developed the main
symptom of caffeine withdrawal or headaches. Depression, anxiousness, feelings of fatigue, and even flu like symptoms were present in ten percent of the volunteers. Not only does caffeine cause trembling hands and insomnia, but too much can lead to diarrhea and excessive urination.
So, the next time you are wondering whether or not you should have that second cup of coffee to perk you up, relax. At least now you know what it will - and won't - do for you!
