Finally, we are receiving more information on labels from soda makers. What a great thing to have another tool that allows us to be aware and in control of how much caffeine we take into our bodies.
But even now that we can see how much of it we are getting, many of us don't know anything about the good, the bad and the ugly when it comes to caffeine. Here is quick breakdown.
First, caffeine is not just found in coffee; it can be found as well in sodas or in chocolate. Also, don't forget they can be found as well in those "pick-you-up" energy drinks and over-the-counter medicine.
The problem is not that you consume caffeine, but rather the amount you consume and your reaction to it.
The good thing about caffeine is that it is a central nervous system stimulant. It increases your basic metabolic rate, which helps you burn more calories (although exercise is still more effective). It temporarily increases your mental clarity, as well as your muscular coordination for activities like typing.
If you are one of many individuals dealing with breathing problems, you should probably also know that caffeine can open up air passages and help to increase respiration rates.
If you have low blood pressure, caffeine can also be a simple way to give it a modest boost. Overall, a dosage of 50 to 100mg of caffeine can have a stimulating effect on your system and increase your daily functions in life.
However, not all of the news is good.
If taken in excess, caffeine can be addictive in a way; to receive the same jolt you get when you first start taking it, you need to gradually increase your dose. Studies have shown that tiredness introduced by caffeine withdrawal can be fixed by additional caffeine intake.
So, you should ask yourself: When you are tired and reaching for your caffeine fix, are you giving yourself energy, or are you managing the withdrawal effect? Studies have shown that the so-called pick-me-up effect is often actually a managing of withdrawal effects springing from addiction to caffeine.
When caffeine is used in excess, your body's own mechanisms do not work as they are intended to. Our hormone levels go out of whack, leading to such symptoms as excess nervousness, irritability, insomnia, dizziness, extreme fatigue, headaches, heartburn, anxiety, hypertension, palpitations. It's enough, frankly, to make you dizzy.
But this is not the whole story.
One of the other issues is the presence of tannic acid, a mild gastrointestinal irritant, in many caffeinated beverages. Get too much of this, and it will hinder the proper absorption of nutrients and minerals that your body needs for proper functioning. These losses most likely will not be replaced with normal nutritional intake.
Many caffeinated beverages also come part and parcel with another stimulant -- sugar. For some, excessive sugar intake can overstimulate the adrenal glands, and persistent usage can even weaken them.
When your adrenal glands do not function well, fatigue sets in. Sugar and caffeine will be little help to help to increase your energy.
A high intake of caffeine is 500 mg daily. A medium intake is between 250 and 500 mg and a low intake is below 250 mg. The following list of beverages and foods, along with the amount of caffeine in each serving, will help you determine the category you fall into:
