Interesting Facts About Water

Ask Men has a feature, "5 Things You Didn't Know About Water" that has some interesting and obvious benefits to the clear, tasteless stuff. Here's a summary of the 5 Things:

Improves mental performance: Water helps the brain move enzymes and nutrients around, and clears out free radicals that can damage cells. Clinical tests show dehydration can impair your short-term memory.

Can prevent critical ailments: Surprise, surprise! Water flushes toxins which helps prevent "minor bugs," and can "decrease the chance of developing cancer." It also helps keep joints lubricated, and flushes excessive salt from your system (which can be hard on the heart).

Keeps you trim: Water is a "proven appetite suppressant," and it speeds up your metabolism. A lot. By 30 percent, according to the piece. This equals up to 5.3lbs of fat per year.

Fights cavities: Saliva neutralizes the acids in your mouth that prevent tooth decay, and has "special minerals that aid in tooth repair. Stay hydrated to keep the saliva coming.

Don't overdo it: Too much water can lead to "digestive problems, seizures or even coma." But to get to that point, you would have to regularly consume two gallons of water per day. And I doubt that's even close to likely for 99 percent of the people that are reading this. So, "I'm trying to avoid a coma," is not a reasonable excuse for passing on a glass of water. Drink up!

Coffee Consumption: Is Heavy Healthier?

Well, since a lot of my coffee posts are about how great it can be for you, I thought it was high time for coverage of a story that says coffee may not be so great.

Over at
ABC News' health portal, I just caught a video that suggests moderate coffee drinkers are at greater risk for a heart attack when they pick up a mug full of the black stuff. (If the video is already gone, check out the story at WebMD.)

According to a Costa Rican study, light coffee drinkers (one cup daily or less) were four times more likely to suffer a heart attack an hour after drinking a cup of coffee. Lack of exercise and other factors may have been at play.

"While doctors can't say that one cup of coffee can cause heart attacks, researchers say it might increase your risk if that java jolt isn't something you're used to," reported ABC News.

Pro Athletes Saving The Placenta

A report I found at Dubai's 7DAYS (via Wired's biotech blog) describes a bizarre new trend where pro soccer players are saving tissue from their newborn's placenta. So far, "eight premiership players in the past year are said to have frozen the stem cells taken from the umbilical cord blood of their newborn," reads the story. Why? The potential use of umbilical cord blood cells for creating new cartilage or ligaments, of course.

Say you're an aging soccer pro and you're knees have gone bad because the cartilage has worn down. They ache and burn, and it's getting harder to keep up with the young bucks in the league. Well, if you've saved your kid's cord blood cells, and the procedure is perfected by researchers, they can grow new cartilage for you from those cells. According to the report, the new tissue, "exactly matches a person’s own, thereby offering opportunities to replace bad cells and reduce the risk of rejection in the event of a transplant."

For the newborn, their future health may be secure as the cord blood cells, "could help rebuild organs, muscles and other damaged tissue if his child needs treatment for a life-threatening illnesses."

11,000 UK parents have already taken the expensive step of banking their children's cord blood cells, reports 7DAYS. But it's still a gamble as the use of cord blood cells for curing ailments, "may be a long way off."

A Suicidal Cure For Cancer?

Suicide is the normal way that cells end their lives. After they've outlived their usefulness, "internal mechanisms kick in and the cell automatically perishes," according to Scientific American. This process, called apoptosis is mysteriously absent in cancer cells. And that what makes them so deadly. But according to a new report by Scientific American, scientists have learned a way to restore the suicidal tendency of cancer cells via chemistry.

Cancer cells are packed with a chemical called procaspase-3, which when activated by a special enzyme turns into caspase-3, or what the Scientific American piece refers to as "an executioner enzyme."

The problem is, the catalyst for transforming porcaspase into nature's little cellular executioner is missing. And that's where modern science comes in. Using a chemical called PAC-1, researchers have been able to coax cancer cells into suicide. The beauty is that cancer cells, with elevated levels of procapase-3, are more sensitive to PAC-1 than healthy cells, so by applying this stuff, you're not forcing the good cells to die premature, self-inflicted deaths.

Viruses To Be Used as Food Additive

Believe it. The FDA has approved a cocktail of six bacteria-killing viruses (bacteriophages) to be sprayed on meat, reports the AP (by way of Wired News).

The viruses will be added to prepared meats like cold cuts, hot dogs and sausages, and kill strains of Listeria monocytogenes bacterium, which makes 2,500 people "seriously ill" each year. An FDA spokesperson told the AP that these meats are vulnerable because they're usually not cooked after being purchased.

According to the FDA, adding specific viruses to food is safe. The viruses being used do not attack human or plant cells, just bacteria harmful to people. However, there is the potential that the helpful viruses may "contain toxic residues associated with the bacteria." But testing has assuaged these concerns.

My question for medical science: when can we expect the first bacteriaphages to be approved for fighting illness? In other words, when will we have the unique opportunity in human history to take viruses to make us better?

Science Replaces Science, Makes a Better Pacemaker

Irregular heartbeats affect more than 2 million Americans. According to our friends at Wikipedia, about 300,000 people die from this condition each year. To fight back, science developed the electronic pacemaker, which 250,000 Americans have implanted each year. But some scientists are working on a new, organic solution.

Researchers from around the world -- UC Davis, Hong Kong, Johns Hopkins University and others -- are working on a bioengineering process that can restore the heart's natural pace-making abilities, reports
ScienceDaily.

The heart loses rhythm when its natural pacemaker, a clump of nerve cells called the sinoatrial (SA) node, is damaged by aging or disease. The new process being developed by researchers may restore damaged SA nodes by delivering a gene which encodes a "bioengineered cell-surface protein" to regular heart cells. This process transforms the regular cells into artificial SA nodes by replicating proteins called HCN ion channels, which keep your heart beating regularly.

Successful tests of this process have already been carried out on animals as large as pigs.

How the Sun Sets on Your Age of Adventure

Is there an age when we all become crotchety old men or stubborn old women that simmer when a teenager cranks up their favorite music, or that turn up our noses when some exotic new food is offered to us? For about 95 percent of us, yes.

The other day, a colleague of mine directed me to an NPR feature, "Does Age Quash Our Spirit of Adventure?" by correspondent Robert Krulwich. In it, they featured the recent studies of Stanford neuroscientist Robert Sapolsky who sought to investigate whether or not our minds are a little less open (to new things) when we're older.

What Sapolsky found it that yes, there is a window when we humans pass "from the adventure novelty stage to the routine and the comfortable and the familiar." This window is extends from age 23 to 39, and affects different preferences in different ways.

For example, according to Sapolsky's investigation, our willingness to listen to new music closes when we're 35. After the age of 23, if you don't already have a body piercing, there's just a five percent chance that you ever will. And if by age 39 you haven't tried a new food like sushi or escargot, there's a 95 percent chance that you never will.

Through the NPR report, I also learned those most resistant to change spend a long time at their jobs, and they're really good at what they do, they become "eminent." In other words, they're comfortable in their ways because they've received positive enforcement, success rewards and so forth. So the key is to change jobs regularly and once you've mastered a profession, position or craft, make a change.

This phenomena, where one's window for trying new things closes, affects other species as well. In one example, a troop of baboons was forced to move from its original habitat. Following the move, the older primates wouldn't touch unfamiliar food sources, but the younger ones would.

What's going on here? Continuity brings stability and, in the case of an old song, can bring us back to the good ol' days. "The familiar makes an older person feel stronger," said NPR's Krulwich.

However, "while continuity may make us feel comfortable, it's when you dare to do that new thing, that's when you grow."

Air Conditioning May Cause Weight Gain

I can't remember exactly when, but a few weeks back I read something about air conditioning contributing to the obesity epidemic in the United States. I remember thinking that was pretty sensational, and probably wrong. Maybe the journalist who wrote that was just trying to come up with an extra excuse for America's bulging waistline to round out a list, and they knew it was a stretch.

Alas, I read at ABC News today that yes, there is a scientific reason for air conditioning (AC) contributing to obesity. According to the report, AC keeps our bodies in the "thermoneutral zone." When in this zone, our body doesn't have to expend energy to make us warmer or cool us down. It's basically a free ride, so our body stores the excess energy as fat.

I know what you're thinking. This is ridiculous! How many excuses do we need to come up with when we know the one answer is, "eat less and exercise more?" Well, think of it this way. The more causes we can identify for gaining weight, no matter how small or trivial, the more ways we can optimize our lives for maximum calorie expenditure.

Scientific American: What Causes A Fever

Over at ScientificAmerican.com, they have a feature called "Ask the Experts," where rubes like myself can go in and learn answers to the biting mysteries in life like, "Why is the sun's corona the hottest layer when it is farther from the sun's core than other layers are." (Get the answer here.) Also, if you're curious about what butterflies do when it ranis, they have an answer for that, too.

Recently, I stumbled across some health related questions. One of which, I'll share with you here.

How Fevers Work
Your body's temperature usually hovers around 98 degrees. That's a prime temperature for bacteria to move in and viruses to reproduce. However, should you crank up the thermostat a couple of degrees, it's suddenly tough for bacteria and viruses to do their business.

Enter the hypothalamus, your body's own thermostat. The hypothalamus monitors body chemistry for "floating biochemical substances called pyrogens," explains Peter Nalin, an Indiana University physician, the Scientific American "Ask the Experts" section. Pyrogens are produced by your body's tissue when it fights disease or by pathogens themselves. So, when pyrogen levels are elevated, the hypothalamus turns up the heat.

By the way, Dr. Nalin confirms that you should indeed, "starve a fever." Basically, turning on your digestive system by eating causes stress and complicates your body's chemistry. Both of these factors have the potential of sending signals to the hypothalamus that encourage it to turn the heat up even further.

Coffee More Healthy Than Fruit Juice?

According to a column at the New York Times, "a typical serving of coffee contains more antioxidants than typical servings of grape juice, blueberries, raspberries and oranges." The piece also explores how coffee consumption can reduce the risk of diabetes, heart disease and cirrhosis of the liver.

In addition to antioxidants, coffee is packed with "phenols, volatile aroma compounds and oxazoles," reports the times. Note that caffeine isn't on the list of beneficial substances. In fact, people that drank decaffeinated coffee, in some studies, got the same benefit as people that drank regular.

The antioxidants in coffee seem to have anti-inflammatory properties as well as control cell damage. Both of these positives can protect against diabetes, heart disease and liver cancer.

However, in the Times piece, they point out that recent studies show caffeine appears to reduce blood flow to the heart. So coffee may not be the best choice for people with heart problems. "I wouldn’t advise people to increase their consumption of coffee in order to lower their risk of disease,” one doctor told the Times, “but the evidence is that for most people without specific conditions, coffee is not detrimental to health."

A Fascinating New Angle on Obesity

It's rare, but occasionally an article comes along that completely flips my way of thinking upside down. Today, I read one of those pieces. It's a feature from the New York Times titled, "Fat Factors," and it investigates the possible link between microbes in the human body and obesity.

Microbes inside me? But I don't feel sick.
According to the Times article, the human body contains trillions of cells, "at least 10 times as many cells… as there are stars in the Milky Way." Astonishingly, 90 percent of these cells are microbes like bacteria, fungi, protozoa and archaea. "Because there are so many trillions of microbes in the gut, the vast majority of the genes that a person carries around are more microbial than human," read the Times article. In total, there are between 395 to 500 different species of microbe in your body right now.

Of course, not all microbes make you sick, or otherwise do harm. In fact, the community of microbes in your body, known as the microflora, does a lot of good. According to the Times feature, "It helps create the capillaries that line and nourish the intestines. It produces vitamins, in particular thiamine, pyroxidine and vitamin K. It provides the enzymes necessary to metabolize cholesterol and bile acid. It digests complex plant polysaccharides, the fiber found in grains, fruits and vegetables that would otherwise be indigestible."

The symbiotic relationship between microbe and man is perfectly natural and lasts from before the cradle until after you're in the grave.

"Microbes colonize our body surfaces from the moment of our birth… they are with us throughout our lives, and at the moment of our death they consume us,” Jeffrey Gordoon of the Center for Genome Sciences at Washington University, told the Times.

The majority of microbes, reported the Times, are in our guts. The thriving culture of microbes in your gut (all 10 to 100 trillion) are called the gut microflora.

So what's the link to obesity?
The gut microflora, according to the Times, "helps extract calories from the food we eat and helps store those calories in fat cells for later use -- which gives them, in effect, a role in determining whether our diets will make us fat or thin."

In theory, the role the microflora play is largely determined by the balance between species of microbes that help you burn calories and microbes that help you store calories. For example, if your gut is thriving with microbes that help you extract lots of calories from food, you're more likely to gain wait.

Does this mean that some people get more calories from, say, a piece of bread, than others? It's possible. Two people with different gut microflora could sit down to a meal of 1000 calories, and one could absorb 750 while the other absorbs 975.

In one experiment described by the Times, mice that were raised in "sterile isolators," and had no microbes, had 60 percent less fat than typical ones despite eating 30 percent more food. When microbes were added to these mice, "they were just as fat as ordinary mice" within two weeks.

Someday, by manipulating the microbes in our body, we may be able to alter the way that we process calories and ultimately store fat. We could take antimicrobial medications to kill a specific type of microbe that makes our body extract more calories from food. After wiping these guys out, voila! We'll all look handsome and gorgeous as movie stars.

But that won't be for a long time. For today, "whatever the reason for any one individual’s tendency to gain weight, the only way to lose the weight is to eat less and exercise more," read the Times column.

Exercise: It's More Than Burning Calories

I constantly hear people complaining about how few calories are burned when exercising. For example, a 190-pound male running (at 5mph) for 30 minutes only torches 200 calories. That's about two slices of toast. To check in on how many calories you can burn doing other activities -- like backpacking, swing dancing or gardening -- visit this great calorie calculator.

No matter what you look into, you're bound to be let down. Thirty minutes of basketball only burns 250 calories. Bicycling only kills 280 calories in half-an-hour. Fifteen minutes of vigorous sex? Just 65 calories.

But there's more to exercise than burning calories. For example, a new research presented at a convention of the American Psychological Association, and
reported by WebMD, shows that "exercise has short- and long-term beneficial effects in improving brain function, slowing age-related cognitive decline, and reducing the risk of dementia."

And it doesn't take much exercise to get these benefits. In one study, just 15-30 minutes of exercise, three times a week, is all it took to protect against Alzheimer's disease.

Surprise, Surprise: TV Health Coverage Sucks

If you're like me, you find that most local news coverage is shallow (to put it kindly). But can you blame them? They're dealing with a very short amount of time, and people's attention spans seem shorter than ever. Whatever the reasons, a new study published in the American Journal of Managed care finds that television health coverage, in particular, is terrible.

In the study,
reported by Forbes, three doctors watched 2,795 full-length news broadcasts and found that health features averaged just 33 seconds. The most heavily covered topics were breast cancer and West Nile Virus. And the doctors concluded that, "few of the newscasts actually provided useful information, while some of the stories were factually incorrect."

Another doctor, not involved with the test, tried to rationalize the coverage. "It's not that the information on the news isn't accurate… but the media tend to go for the medical news that's most exciting or most interesting, and too often most alarming."

One of the survey's authors pointed out that, after sounding the alarm, newscasts often move on to other stories without providing solutions. The example given was West Nile Virus. Newscasts will tell you that West Nile is a killer, but they won't tell you how to protect yourself from mosquito bites.

Isn't that brilliant? Bear in mind, people tune in when they're terrified. So long as you report on a problem without solutions, people will keep coming back for the latest developments.

Finally! Good News for Smokers

Researchers at the Parkinson's Institute have found that nicotine may protect against Parkinson's disease, according to a press release at EurekAlert.

What's Parkinson's again?
Parkinson's disease is "a progressive, neurodegenerative disease caused by the death of small clusters of cells in the midbrain," read the Parkinson's Institute release.
According to Wikipedia, "[Parkinson's] is often characterized by muscle rigidity, tremor, [and] a slowing of physical movement… the primary symptoms are due to excessive muscle contraction, normally caused by the insufficient formation and action of dopamine."

Lucky for smokers, results of the Parkinson's Institute study suggests that nicotine reduces the loss of dopamine-containing brain cells by up to 50 percent.

And now the bad news.
According to the CDC, smoking is the leading cause of preventable death in this country, and it kills about 440,000 people annually.

100-Calorie Snack Packs Take Off

Have you seen those 100-calorie snack packs of cookies, chips and other junk food at the store? Ever wonder who's buying those? Well, according to a Newsweek report, there are a lot of people buying these things.

The 100-calorie packages were launched by Kraft in 2004. In the first year alone, the food giant took in $100 million on these small snack packages. This is a sales record that "fewer than one percent of new packaged-good products in the past decade have achieved," one expert told Newsweek.

Of course, with sales like theses, this is just the beginning. In the first half of this year, 42 more 100-calorie products have hit shelves. By contrast, it took all of last year for that many 100-caorie products to be released.

My question: are people really eating less? Are they stopping themselves at a single 100-calorie bag of wheat thins, instead of eating 500-calories worth straight from the box. Or are they eating five of those little 100-calorie bags, and gaining as much weight as ever?

Call me a pessimist, but my bet is that one snack equals about five 100-calorie pouches, the same as someone would have eaten if they had a conventional-sized package.

In Brief: Obesity Vaccine, 'Scorpion Venom' Does Good

Interesting new developments in health science show promise for ending obesity with a shot and killing tumors with synthetic scorpion venom.

Obesity vaccine
Earlier, I posted on research at Yale that identified an
enzyme in your body linked to obesity. This got me to thinking of a day when doctors may prescribe a fat pill to make us slimmer. Well, new research from the Scripps Research Institute in California suggests that day may be closer than I thought.

According to
a report at the BBC, Scripps researchers have come up with a vaccine that "prompts the body to produce antibodies against ghrelin, a hormone that stimulates hunger and weight gain." While the vaccine may curb hunger, rats on the drug that ate normally still lost more weight than non-medicated rats, suggesting that ghrelin has an affect on metabolism as well.

While the study's results are intriguing, I think it sounds too good to be true. And more tests are sure to come. One professor told the BBC, "Since ghrelin is present in the brain you might start an immune system response against the brain. It's not necessarily a very safe thing to do."

Another innovative tumor treatment
Recently, I described an
innovative treatment for tumors that involves choking tumors with bubbles. And I just read at the BBC that another unlikely hero in the fight against tumors has arisen: synthetic scorpion venom. In the BBC article, we learn that TM-601, "a synthetic version of a peptide that naturally occurs in the venom of the giant yellow Israeli scorpion," can pass through the bloodstream and bind to the cells of a particularly nasty form of cancer: glioma brain tumors. Just eight percent of patients survive this disease. The good news: the synthetic-venom treatment is already being tested on patients at Cedars-Sinai Medical Center in California.

Bikini With Computer Chip for Sale, Sun kills…

According to the World Health Organization (WHO), 60,000 people die each year from skin cancer caused by overexposure to the sun's rays, according to a CNN report. Of course, sunlight helps your body produce vitamin D, which has a surprising number of potential benefits. (See a complete posting on vitamin D here.) But if you overdo the sun, you're at risk of being one of the thousands that die from skin cancer.

The WHO report recommends that you stay out of the sun as much as possible, use a sunscreen with an SPF rating of 15 or more, and "stay out of tanning salons," according to the CNN story.

But if you simply must frolic in the sun wearing as little clothing as possible, say dressed in a bikini, then a Canadian company, Solestrom, has a product for you.
According to another CNN report, Solestrom is selling a $190 bikini with a computer chip that sounds an alarm when UV intensity reaches dangerous levels.

Solestrom is aiming for a cut of the $811 million bikini market. U.S. sales of bikinis jumped almost 19 percent over the last year to reach 33.6 million, reports CNN.

Vitamins: Another One B-ites the Dust

This has been a rough year for foods and vitamins that we once thought were extremely helpful for our bodies. When I started this blog in May, three of the first 12 posts were about health favorites like green tea, soy and multivitamins turning out to be not-so-healthy. They're still good for you, just not as good as we once thought.

And now, just a few weeks later, there's another health superstar to knock down a peg: vitamin B.

Why has vitamin B been bumped to the B list? So far this year, we've learned that vitamin B does not appear to lower the risk of heart attacks, strokes or improve memory as once thought.

Previously, it was suggested that vitamin B could help maintain memory in our Golden Years. However, a study reported by CNN finds that, "B vitamin pills failed to help keep elderly people's brains and memories sharp in the longest study yet to test this approach."

Also, the Washington Post reports that B vitamins, "do not appear to lower the risk of heart attack and stroke," as once thought.

The same Washington Post link also pointed out that new study's show echinacea does not appear to fight the common cold, multivitamins are not a silver bullet against chronic diseases and calcium supplements are not a very good way to protect against brittle bones.

Science may come up with a pill, or two, or five hundred (if pharmaceutical companies have anything to say about it) that act as silver bullets against disease and disorders. But for now, it seems like healthy diets and exercise are your best defenses.

How Salt Can Harm

You hear a lot about how salt is bad for you, but you also hear that doctors disagree on how harmful it is. Also, I noticed you almost never hear exactly how salt is bad for you. They just tell you salt is bad, not how it's bad. So I decided to investigate.

What got me going on this salt topic is a story at the Washington Post: "
Rx for Salt: Cut It Out." In this article, there are some pretty sad statistics. For example, if you're over 55, you have a 90 percent chance of developing high blood pressure. Thirty percent, or 65 million Americans already have this problem. Thus, as the Post points out, the AMA is on a campaign to reduce the salt in our food. They're calling for a 50 percent cut in the sodium that goes into processed foods, and for the FDA to "revoke salt's status as a food ingredient 'generally recognized as safe,'" reports the Post.

Also in the Post report, they point out that a number of factors lead to high blood pressure: inactivity, obesity, alcohol consumption and, of course, salt. But instead of calling for people to get up and exercise, eat less food or cut out the alcohol, the article goes on to single out salt as the one villain to be defeated. Why is that? I'm not sure. But I did decide to get the facts on salt, and
I found them at the BBC News' Medical Notes section.

First, here's why you need salt
Salt does three main things for you. "Sodium helps to maintain the concentration of body fluids at correct levels. It also plays a central role in the transmission of electrical impulses in the nerves, and helps cells to take up nutrients," reports the BBC.

But in large amounts, salt can harm
If you eat too much salt, your body can retain too much water and other bodily fluids. Excess bodily fluid may put a strain on your system. For example, too much fluid in the brain can lead to weakness in its blood vessels, which can cause stroke. And a greater volume of blood means your heart is working harder, which may lead to heart disease.

Alas, there is some disagreement over the link between salt, heart disease and stroke. I'm sure it's hard to isolate salt as the single factor when people with heart disease may also be overweight, inactive and consuming a lot of alcohol. My unprofessional advice? Occasionally indulge in salty foods, alcohol and a good, fun junk food binge. But please, don't make it a habit. Instead, make exercise a habit. As much of a pain in the butt as that can be, make like Nike and just do it.

Advances in Science May Make Us Slimmer, Tougher

After reading a couple of headlines at ScienceDaily.com, it occurred to me that we're closer than ever to a future where scientists can program our bodies to burn more fat, turn off pain and resist heart disease.

Boosting metabolism
At Yale, researchers isolated an enzyme, MKP-1, which appears linked to obesity in mice. When the rodents were bred without MKP-1, they were, "resistant to weight gain despite consuming high fat foods and eating more than control mice," read the ScienceDaily report. Scientists aren't sure exactly how MKP-1 affects the body's metabolism, but when they do, fad diets could be a thing of the past.


Making pain go away
Over at Columbia University, scientists have found "a protein in nerve cells that acts as a switch for chronic pain,"
reports ScienceDaily. They've applied for a patent for drugs that will turn this switch off. What makes this potential class of drugs different is that they focus on "first order" neurons, which are the neurons at the source of pain (for example, your thigh or fingers). Traditional pain medications focus on heading off pain signals at "second order" neurons, which are in your spinal cord.

Lowering the risk for heart disease
In your blood is a protein (SecA) that "enables bacteria outside the human body to travel through the blood stream and infect organs such as the heart,"
according to a ScienceDaily column. But what if you could regulate this protein? That's exactly what a team of Rutgers-Newark scientists are working on. One scientist told ScienceDaily, "by identifying the way this motor protein works, at some point we will be able to develop drugs that can block the secretion of these proteins or limit the activity of SecA causing the bacteria to die before it can reach its destination."

About Me

My photo
I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
