Drink To Your Health

[media id=15 width=500 height=400]

Scientists have found a substance in red wine that is slowing down the aging process in mice. Will it someday lengthen the lives of humans, too? Morley Safer reports.

Ingredients

Generally energy drinks include methylxanthines (including caffeine), vitamin B and herbs. Other common ingredients are guarana, acai, and taurine, plus various forms of ginseng, maltodextrin, carbonated water, inositol, carnitine, creatine, glucuronolactone and ginkgo biloba. Some contain high levels of sugar, and many brands also offer artificially-sweetened ‘diet’ versions. The central ingredient in most energy drinks is caffeine, the same stimulant found in coffee or tea, often in the form of guarana or yerba mate.

The average 237 milliliter (8 fluid ounce) energy drink has about 80 mg of caffeine, with 480 mL (16 fl. oz.) drinks containing around 150 mg.

Desirable effects

A variety of physiological and psychological effects attributed to energy drinks and/or their ingredients have been investigated.

Two studies reported significant improvements in mental and cognitive performances as well as increased subjective alertness. Excess consumption of energy drinks may induce mild to moderate euphoria primarily caused by stimulant properties of caffeine and may also induce agitation, anxiety, irritability and insomnia. During repeated cycling tests in young healthy adults an energy drink significantly increased upper body muscle endurance. It was also suggested that reversal of caffeine withdrawal is a major component of the effects of caffeine on mood and performance.

Restorative properties were shown by a combination of caffeine and the sugar glucose in an energy drink, and some degree of synergy between the cognition-modulating effects of glucose and caffeine was also suggested. In one experiment, a glucose-based energy drink (containing caffeine, taurine and glucuronolactone) was given to eleven tired participants being tested in a driving simulator. Lane drifting and reaction times were measured for two hours post-treatment and showed significant improvement.

Two articles concluded that the improved information processing and other effects could not be explained in terms of the restoration of plasma caffeine levels to normal following caffeine withdrawal.

Adverse effects

Caution is warranted even for healthy adults who choose to consume energy beverages. Consumption of a single energy beverage will not lead to excessive caffeine intake; however, consumption of two or more beverages in a single day can. Other stimulants such as ginseng are often added to energy beverages and may enhance the effects of caffeine, and ingredients such as guarana themselves contain caffeine. Adverse effects associated with caffeine consumption in amounts greater than 400 mg include nervousness, irritability, sleeplessness, increased urination, abnormal heart rhythms (arrhythmia), and stomach upset. The concentration of sugar in a sports drink is recommended to be 6-7% carbohydrate to allow maximum absorption and minimize spikes and crashes in blood sugar. Higher concentrations such as those seen in energy drinks will slow fluid absorption into the blood and energy system, increasing the possibility of dehydration. When a high level of sugar is in the blood stream the body cannot get the water into the cells that it needs because the water is busy trying to dilute concentration of sugar in the blood stream. The actual number of people suffering from adverse effects is difficult to measure since many cases go unreported.

In the United States, energy drinks have been linked with reports of nausea, abnormal heart rhythms and emergency room visits.The drinks may cause seizures due to the “crash” following the energy high that occurs after consumption.Caffeine dosage is not required to be on the product label for food in the United States, unlike drugs, but some advocates are urging the FDA to change this practice.

Until 2008, France banned the popular energy drink Red Bull after the death of eighteen-year-old Irish athlete Ross Cooney, who died as a result of playing a basketball game after consuming four cans of the drink The French Scientific Committee (J.D. Birkel) concluded that Red Bull has excessive amounts of caffeine. Denmark also banned Red Bull. Britain investigated the drink, but only issued a warning against its use by pregnant women and children.

Yoga may decrease age-related dowager’s hump

Are you at risk for dowager’s hump? Findings from a small study suggest you may want to try yoga to decrease this age-related curve of the upper spine.

Among a group of elderly study participants, those who did yoga for six months saw their upper spine curve lowered by about 5 percent compared to those who did no yoga, Dr. Gail Greendale, at the University of California at Los Angeles, and colleagues report in the Journal of the American Geriatrics Society.

Those with greater spinal flexibility showed a 6 percent improvement in their upper spine curve, which suggests yoga “when the spine is relatively more malleable” may be most effective, Greendale said.

“Men and women with more flexible spines at the start of the study got even more benefit from the yoga,” Greendale told Reuters Health in an email.

Greendale’s team took regular measurements of the upper spine curvature of 118 otherwise healthy individuals with indicators of moderate hyperkyphosis – the medical term for dowager’s hump.

The study group was mostly — 81 percent — female, about 75 years old on average, and reported almost no physical limitations. However, about three-quarters reported body pain during the 4 weeks prior to study entry, and 60 percent said their pain was frequent or daily.

On 3 days each week for 6 months, 58 individuals took yoga classes using breathing techniques and poses to increase awareness, flexibility, and strength of their back muscles. The remaining 60 participants (the control group) attended 6 monthly informational luncheons.

Compared with spinal curve measures at study entry, the yoga group showed decrease spinal curvature, while the control group had increased curvature, after 6 months.

Newton’s Apple

Myth: Newton devised his universal law of gravity when an apple fell on his head from the tree under which he was sitting

It is always exciting to think of a great discovery happening in the blink of an eye due to a coincidental event – we consider that if it were not for the right person being in the right place at the right time, man would have lost an incredibly significant piece of knowledge. For this reason people have clung to the idea that Newton devised his universal law of gravity because of an apple hitting him on the head. But in fact the first mention of an apple in relation to Newton came 60 years after his death: “Whilst he was musing in a garden it came into his thought that the power of gravity (which brought an apple from the tree to the ground) was not limited to a certain distance from the earth but that this power must extend much further.” (John Conduitt)

Interesting Fact: Though he is better known for his love of science, the Bible was Sir Isaac Newton’s greatest passion. He devoted more time to the study of Scripture than to science, and he said, “I have a fundamental belief in the Bible as the Word of God, written by those who were inspired. I study the Bible daily.” He spent a great deal of time trying to discover hidden messages within the Bible.
