Highly Caffeinated Drinks Produce Slower Responses, Scientists Find

December 7, 2010 by  

Highly-caffeinated drinks produce slower responses, scientists findIn the wake of the increasing popularity of energy drinks, researchers from Northern Kentucky University recently conducted a study to examine the effects that these sugary and highly caffeinated drinks have on the younger population — especially college students.

The scientists noted that while moderate consumption of sugary drinks are known to improve behavior control, these benefits can disappear as individuals drink these beverages more often.

For the study, a total of 80 college students between the ages of 18 and 40 were analyzed. Some of the participants were given energy drinks while others consumed soda that contained less caffeine. Another group was considered to be controls, as they did not drink any caffeine.

The subjects each took a computer test approximately 30 minutes after finishing their designated beverages. The researchers also analyzed how mentally tired the participants felt during this time.

While the students who had consumed the energy drinks reported feeling less tired compared to the other groups, the response rates were slower among these individuals.

Cecile A. Marczinski, Ph.D., the study's co-author, said that there needs to be a better understanding "in regard to content labeling and possible health warnings" about highly caffeinated beverages.

According to the Centers for Disease Control and Prevention, 34 percent of individuals who are 18 to 24 years old consume energy drinks.

    If people got proper nutrition, they wouldn’t need energy drinks. Our society has always had the best access to a variety of foods…do we eat them? No. We have become a fat nation that eats only phud, the junk made by scientists and given to us as our daily bread. It’s crap. It does not nourish our bodies. It causes mental sluggishness. It’s like trying to fly a jet using kerosene for fuel. I am appalled at what I see people buying in the store: sugary sweet cereals, processed foods that are so processed they don’t even resemble food, canned this, and boxed that…Most times not a single fresh vegetable or fruit.
    Big agribusiness has depleted our soils of essential minerals so much that the fruits and veggies we do eat are they, themselves depleted. And now S510 is trying to shut down organic and small farms? What the hell is happening to America? They have got people so dumbed down by malnutrition that they are zombies.
    It’s all a scheme…

    Kim, don’t you know? has nobody bothered to talk to you and tell you the truth?

    To answer you question as simply as I can, its the water, the one beverage, the only beverage the body needs, has ever needed, and it is poisoning our mind. Its can’t poison our body and kill it like the real poisons do by its attacks on the liver and kidneys, etc. The water we drink is not H2O in its pure form, no, no, no its laced with some chemcials that the body does not deal with very well, They do not kill the body because the body has a working immune systen that either flushes out unwanted chemicals and substances or it stores them up somewhere in the body for later considerations.
    One chemical we know of and willing allow to have placed in our water by the very Government we should be able to trust to protect and care about us is Fluorine, a by product of yet another manufactured product that we do need and use in out everyday lives.
    For over 50 years Fluoride (Fluorine) has been openly but misguidedly placed in the water of every major and minor city in America to simply get rid of it and more importenly make a extra few million bucks for the Aluminum smelting plants in this world.
    Did you know China is selling bags of deadly Fluorine to Public Works Departments in America to put in the water the people drink under ther care.
    I regress,,, Its a known fact that the IQ of people who have been drinking Fluoridated water all their lives have a lover IQ than people of other nations around the world. Much lower IQs is what happens when the immune system looks for something to do with the Fluorine the body has inguested in the water. Unfortunately it finds a place to dump it in the part of the brain that developes Intelligence and that something the brain does not welcome or need.

    If you find it hard to believe what I say,, well,,, perhapes the Fluoride in the water has done what the Government wanted.

    Has it made you dumber than you should be?
    It did me. But at 73 what the hell do I need a high IQ for.
