Exercise Takes Toll on your Eyes…but Caffeine Restores Them!

Everyone knows that caffeine can help you exercise better and longer, but most of us don’t realize that caffeine can reverse a detrimental effect that endurance exercise can have on your vision.


In a University of Waterloo study, participants experienced an almost 10 per cent reduction in their rapid eye movements after performing endurance exercise.  However, ingesting caffeine reversed the effect entirely!

A group of scientists at the University of Waterloo School of Optometry and Vision Science recently explored the effects of caffeine and endurance exercise on participants’ eyesight.

To do this, they asked 11 well-trained cyclists to ride for three hours at a moderate intensity and then to take a rapid eye movement test afterwards.  Additionally, participants were given either a placebo or caffeine-infused beverage to test for moderating effects.

Cyclists given only the placebo showed an eight per cent decrease in their eye movement speed after performing the exercise session.  The decrease in eye movement is probably caused by a phenomenon known as “central fatigue,” in which the nervous system is unable to coordinate muscle movements effectively.

However, ingesting caffeine (the equivalent of two cups of coffee) was found to counteract the effect entirely.  The members of the group that took caffeine after the workout saw their eye movements increase by nearly 11 per cent following exercise.  Although the exact mechanisms by which caffeine eliminates the effects of exercise-induced fatigue are unknown, the authors suggest that it probably affects the working of of neurotransmitters.

Most runners will agree that they feel more alert and energetic while and even after completing a run or bout of exercise.  These advantages may be especially important for early-morning runners who then drive to work or require a high degree of focus and concentration.

Monster Sues in Federal Court over Caffeine in Energy Drinks

It is astonishing to us, but the brouhaha over the caffeine content of so-called “energy drinks” never seems to end.  We should repeat that an average energy drink contains about 80mg of caffeine, in comparison with 150mg of caffeine in a 6oz cup of Arabica coffee or 400mg of caffeine in an 8oz cup of Robusta coffee.

In other words, a cup of coffee delivers two to five times the amount of the caffeine in an average energy drink! 

Nevertheless, the crusade against energy drinks, because of their “high” caffeine content, goes on and on.  Now, San Francisco has tried to ban these drinks because of their caffeine content.  Monster Beverage Corporation, that makes these energy drinks, has filed suit in federal court to overturn that city’s incomprehensible, oppressive enactment.

Established in 2002, Monster has regularly been targeted by phony lawsuits concerning its products’ caffeine content, and the company was sued in February by five people who falsely allege that their long-term consumption of the company’s drinks caused irreversible and near-fatal health problems, including heart attacks, strokes, and renal failure.

Caffeine paranoia goes on and on and on!

Coffee Beetle Withstands Extremely Toxic Concentrations of Caffeine

Coffee Berry Borer

The coffee berry borer is the most destructive coffee pest in the world.  This coffee beetle, found in most regions where coffee is cultivated, can reduce a crop yield by 80 percent.

This insect is the only coffee pest that uses the coffee beans as its sole source of food.  It bores into the bean and spends most of its life tucked inside, where it’s exposed to what we might think would be an extremely toxic amount of caffeine for its mass:  the equivalent of a 150-pound person drinking 500 shots of espresso.

Caffeine evolved as an insecticide and anti-microbial to protect plants.  But the coffee berry borer relies on the bacteria in its gut to degrade and detoxify caffeine.  Researchers also found the most prevalent of these bacteria boasts a gene that helps break down caffeine.

The war against the coffee berry borer beetle continues.  “Instead of using pesticides, perhaps we could target the coffee berry borer’s gut microbiota.  We could develop a way to disrupt the bacteria and make caffeine as toxic to this pest as it is to other insects,” says Javier Ceja-Navarro, a scientist in Berkeley Lab’s Earth Sciences Division and lead author of the paper.

The scientists analyzed coffee berry borers from seven coffee-producing regions:  Mexico, Guatemala, Puerto Rico, Hawaii, India, Indonesia and Kenya.  They also studied a colony reared at the USDA’s lab in Beltsville, Maryland.

The scientists immersed the gut bacteria in a special medium containing caffeine as the main nutrient, so only the bacteria that degrade caffeine survived. Fourteen bacterial species were isolated, most of which were found in beetles from all seven coffee-producing regions and the laboratory colony.  These bacteria appear to subsist on caffeine as their sole source of carbon and nitrogen.  One of the bacteria, Pseudomonas fulva, was the most prevalent, according to their DNA-based geographic survey.

The research was funded by the U.S. Department of Agriculture, the Laboratory Directed Research and Development program at Berkeley Lab, and Mexico’s National Council for Science and Technology.

Caffeine-Based Gold Compounds May Fight Cancer

It has been known for some time that caffeine can kill cancer cells.  In fact, the therapeutic power of caffeine has been documented for potentially treating brain cancer, head and neck cancer, breast cancer, uterine cancer, liver cancer, skin cancer, oral/pharyngeal cancer, colon cancer, prostate cancer, and even lung cancer.  Now, researchers report in the American Chemical Society journal Inorganic Chemistry that a combination of a caffeine-based compound with a small amount of gold could someday be used as an anticancer agent. Cancer researchers Angela Casini and Michel Picquet and their colleagues note that even though caffeine may serve as a possible anticancer treatment, drinking gallons of coffee, sodas and energy drinks is not practicable.  The reason is that the amount of caffeine in these drinks might start to have harmful effects on healthy cells, too, at the levels necessary to kill cancerous ones.  However, because gold can wipe out cancer cells also, and, like caffeine, it can harm healthy cells, the research team put the two together to see whether the new caffeine-based gold compounds could selectively stop cancer cells from growing without hurting other cells. Researchers made a series of seven new compounds, called caffeine-based gold (I) N-heterocyclic carbenes, in the laboratory and studied them. They found that, at certain concentrations, one of the compounds of the series selectively killed human ovarian cancer cells without harming healthy cells. Breakthroughs like this one support the tremendous value of CHAT, Inc. (Caffeine Health and Therapeutics, Inc.), an organization that is currently being founded as a non-profit corporation to encourage and promote research into and the development of pharmacological derivatives of caffeine that offer improvements over caffeine’s numerous established therapeutic and health benefits.  For information about CHAT, Inc., write to CHAT@WorldofCaffeine.com.

Wake the Dead with Caffeine!

An Englishman was recently was found dead in his West Midlands flat, and, at his inquest, the Black Country Coroner, Mr. Robin Balmain, blamed his death on a “massive overdose of caffeine.”  In fact, the man had consumed a bag of twelve caffeinated Hero Instant Energy Mints containing a total of 500 mg of caffeine.  This is about the amount of caffeine in two 8 oz cups of filter-drip Arabica coffee or of a large cup of Starbucks burned Robusta brew.

This coroner announced he would write to the Department of Health to express concerns over the death of the former painter and decorator.  He said, “This is a potentially very dangerous situation.  The level of caffeine is enormous.”

Still Alive!

The good news is that, if this Englishman really was not exposed to any other cause of death, then he must still be alive!  This is so, because such small amount of caffeine would not kill anyone.  If it could, stretchers would be filled with Starbucks patrons and other coffee drinkers, carrying them to emergency trucks and to the morgue.

Obviously, caffeine paranoia is alive and well!  Reasonable people would do well to sit down, enjoy a cup of caffeinated coffee or a caffeinated energy mint, and recognize that, for most of us, caffeine safely boosts our mood and improves our health.

Judge Converses with Horse

Perhaps you sometimes wonder why our government is run so poorly.  One reason might be the intellectual incapacity of our judges, our legislators, and our President.  And, possibly, if these people would use more caffeine, they just might be a bit smarter and more competent.  This video illustrates the mental weakness of one judge who, obviously, just doesn’t use any caffeine!
