Last Song Syndrome? Why Catchy Songs Get Stuck In Your Head, Plus How To Get Rid Of Earworm

Leave a comment

Many of us have experienced last song syndrome: We get in the car, turn on the radio, and hear the same top 40 songs on repeat every hour. Suddenly, we catch ourselves humming the melody of a song, and hear it play on a continuous loop in our heads. So, what makes some songs catchier than others?

Researchers at Durham University suggest some songs are more likely to stay with us based on their melodic content.

“These musically sticky songs seem to have quite a fast tempo along with a common melodic shape and unusual intervals or repetitions like we can hear in the opening riff of Smoke On The Water by Deep Purple or in the chorus of Bad Romance by Lady Gaga” said Dr. Kelly Jakubowski, lead author of the study from the Department of Music at Durham University, in a statement.

About 90 percent of us experience an earworm at least once a week, with some of us having them more than others, according to Jakubowski. It normally happens at times when the brain is not doing much, such as being in the shower, walking, or doing chores.

In the study, published in Psychology of Aesthetics, Creativity and the Arts, researchers identified three distinct characteristics that make up an earworm: pace, shape of the melody, and a few unique intervals.

In terms of pace, earworms are faster and more upbeat in tempo and have rhythm people could move to. For example, previous research has found songs on a running or workout playlist tend to transport athletes into a state known as “flow,” which is when people are completely immersed in what they’re doing and feel as if they’re functioning on autopilot. Typically, a workout playlist will start with warmup and stretching music, and then transition to cardio songs, which gradually increase in intensity. The playlist migrates to strength-training tunes, and then concludes with mellow cool-down songs.

These songs are also more likely to be earworms, because of their gradual increase in intensity, followed by a decrease, and increase in between.

A song’s melodic contour, or musical shape determines whether it’s an earworm. These songs are simple in structure, but possess a rhythmic pattern. For example, the nursery rhyme “Twinkle, Twinkle, Little Star” rises in pitch, but it goes back down low and then rises again as a partner. This easy-to-remember melody makes a song an inevitable earworm.

A more recent example is Maroon 5’s opening riff of “Moves Like Jagger,” one of the top-named earworm tunes in the study. It follows a common contour pattern of rising then falling in pitch.

Lastly, an earworm song possesses unusual interval structure, such as some unexpected leaps or more repeated notes than we would hear in the “average pop song.” The instrumental riff of The Knack’s “My Sharona” contains an unusual interval structure.

To obtain this data, the researchers used an online survey to ask 3,000 people for their most frequent earworm tunes. They compared them to tunes that had never been named as earworms in the database, but were a match in terms of popularity, and how often they were in the UK Music Charts. Melodic features of earworm and non-earworm tunes were analyzed and compared. The songs were limited to popular music genres, such as pop, rock, rap, rhythm & blues. (R&B).

The most frequently named earworms included:

Bad Romance – Lady Gaga

Can’t Get You Out Of My Head – Kylie Minogue

Don’t Stop Believing – Journey

Somebody That I Used To Know – Gotye

Moves Like Jagger – Maroon 5

California Gurls – Katy Perry

Bohemian Rhapsody – Queen

Alejandro – Lady Gaga

Poker Face – Lady Gaga

“We now also know that, regardless of the chart success of a song, there are certain features of the melody that make it more prone to getting stuck in people’s heads like some sort of private musical screensaver,” said Jakubowski.

So, how do we get these earworms out of our heads?

A 2015 study in the Quarterly Journal of Experimental Psychology claims that chewing gum provides a simple solution. In a series of experiments, participants who were given gum to chew reported fewer earworms than those who weren’t. The researchers hypothesize since our vocal apparatus is involved in singing, when our jaws are otherwise engaged, our ability to imagine music is impaired.

At least we have a better understanding why we still can’t get Kylie Minogue’s 2002 hit song “Can’t Get You Out of My Head” out of our heads.

THE 9 BEST WAYS TO GET RID OF MUSCLE CRAMPS

Leave a comment

You’ve probably been stopped in your tracks by a spasm the size of a golf ball in your calf, a charley horse, or a tremor that constricts your hamstrings. Like side stitches, muscle cramps are a reality for many runners, lifters, cyclists, and swimmers alike.

The main difference between side stitches and cramps is that the latter occurs in smooth involuntary muscle (more specifically, your diaphragm) while more common muscle cramps occur in large skeletal muscle that’s under your voluntary control (i.e. your leg muscles). The cramps are sudden, painful, and can really throw off a workout (or your sleep). Of course, you know this if you’re prone to muscle cramping. So, why do they happen in the first place?

“Cramps are not well understood, but there is research to show that cramps occur from changes in motor neuron excitability or random discharges of motor nerves that cause sudden—sometimes very painful—involuntary contraction of a muscle,” says Marni Sumbal, MS, RD, CSSD, LD/N, endurance athlete and owner of Trimarni Coaching and Nutrition.

“Athletes who experience cramps may experience them during exercise (exercise-induced cramping) due to muscular fatigue or shortened muscle contraction (a.k.a. tight muscles and limited range of motion),” Sumbal says.

For expert-backed tips on preventing muscle cramps, alleviating pain when they strike, and keeping them from happening again, read on.

1. Do a proper warmup

Always warm up with a combination of dynamic and static stretching(Read: Warmup Tips: How to Use Static and Dynamic Stretching to Become a Better Athlete). When you incorporate both types of stretching into a full warmup routine with aerobic components and drills, you optimize your exercise performance and reduce your chances of straining muscles. Plus, by priming your major muscle groups—flooding the areas with blood—you prepare them for higher intensity movements. In short, you’re not shocking your system and causing muscles to lock or tighten due to stress.

2. Keep carbs handy—and hydrate!

Sumbal says to stay well hydrated during the day before you work out, during the workout (if you’re logging a good distance—and even more so if it’s hot), and after. Dehydration can play a role in muscle cramps because when you lose fluids and electrolytes like like sodium and potassium, you disrupt the balance of fluids in your body. In turn, this increases the excitability of your nerves and prompts your muscles to spasm. You should also consider drinking an electrolyte-carb beverage for workouts over 75 minutes, she says.

“You need to use sport nutrition (carbohydrate-based products) during long workouts when fatigue is most likely to occur,” Sumbal says. This isn’t necessary for a 5 or 10K, but if you’re logging 10+ miles, consider storing these foods and performance products to boost your energy and power you through the finish line. This is especially important for triathletes or people competing in endurance events like IRONMAN or Ragnar races who want to avoid the muscle cramping, stomach pain, and exhaustion symptomatic of bonking.

“We not only lose fluids when we sweat—which can be replaced with beverages—but the levels of several electrolytes that are essential to fluid balance and neuromuscular functioning also decrease—especially sodium,” says Beatriz Lara, a lead researcher from the Exercise Physiology Laboratory at Camilo José Cela University. Her research suggests endurance athletes like marathoners can lose liters of fluids during a race, and if those fluids aren’t replenished, the excessive electrolyte loss can cause a condition called hyponatraemia. When your sodium concentration is less than 135 mmol/L in the blood it can lead to decreased or loss of consciousness—and worse. (That could make those muscle cramps seem like a walk in the park, huh?)

3. Improve your range of motion

“Work on mobility to improve your range of motion—especially if you’re commuting a lot or working a desk job,” Sumbal says. Mobility drills really help open up tightness so you can settle into movements that might otherwise strain your muscles—causing them to spasm and cramp.

If you’re looking for a routine that will build muscle, improve mobility, and bulletproof your joints, try The Perfect Workout. If you want fitness experts’ secrets on improving total body mobility, read The Fit 5: Better Body Mobility.

4. Relax your body

It’s difficult during high-intensity movements like sprinting, but try to relax your body when you’re training. Mid-run try to think about relaxing your face, unclenching your jaw, and keeping your fingers from forming a fist. It may seem nit-picky, but you’re wasting energy and putting unnecessary force on small and large muscles throughout your body. “Many newbie swimmers suffer from hamstring and calf cramps from being too tense in the water,” Sumbal adds. “Yoga may help with this,” she says, since the practice teaches you to zero in on tasks that challenge your strength and flexibility all while keeping that mind-body connection. .

5. Take it slow

“Progress slowly with your training,” Sumbal suggests. If you’re training for a marathon, you can’t jump from logging three miles a day to 12. Your muscles won’t have the time to cope, so you can expect straining and cramps. “Don’t take any shortcuts and progress your training gradually so you adapt overtime.”

6. Foam roll before and after workouts

“Most athletes will benefit from light foam rolling and mobility work before and afterworkouts,” Sumbal says. Loosen up your hip flexors, which are notoriously tight, and break up any knots in your hamstrings, quads, and calves. You’ll be markedly more comfortable and relaxed by taking the time to roll out tightness and soreness beforehand, and even more benefits if you do it after as well.
7. Massage the muscle

“If a cramp occurs during a workout, stop immediately and try to relax,” Sumbal recommends. Never try to push through the cramp because you’ll only aggravate it more. “You can lightly massage the muscles to relax the contraction,” she adds. Light stretching will help, too. Just don’t over-do it since that can cause the onset of new cramps.

8. Strengthen your small and large muscles

“Strength training is important; you can strengthen the muscles so they do not fatigue as quickly,” Sumbal says. “Don’t just target the major muscle groups, though,” she adds. Foot strength is super important and causes a whole slew of problems—from the ground up. Work on picking up marbles with your toes or grabbing a towel and picking it up and dropping it down from side to side.

9. Check out breaking science

Sumbal says to check out the latest on a sports beverage that targets the nervous system called It’s the Nerve. It’s not yet released but is in development by Rod MacKinnon M.D., Nobel Prize winning neuroscientist and endurance athlete. MacKinnon set out to create a solution to muscle cramps after suffering a bout while kayaking. According to his site, “When under stressful conditions—such as fatigue, heat, severe electrolyte loss, reduced blood flow—nerve function can deteriorate and cause an excessive firing of motor neurons, which ultimately causes muscles to cramp. Our product’s blend helps stabilize the activity of the motor neurons and thereby prevents muscle cramps.”  (Though we’re not sure yet what the “blend” is, all of the active ingredients are included on the FDA’s list of ingredients that are Generally Recognized As Safe (GRAS).)

Mitochondria, Telomeres, Strength Training & What It Means For Something To Qualify As An “Anti-Aging” Activity

Leave a comment

 

In his excellent article series on anti-aging, anti-aging fitness expert Clarence Bass highlights this study showing that six months of progressive resistance training made the gene expression pattern of aging mitochondria appear significantly younger. 

Muscles can become smaller and weaker with age (a process known as sarcopenia), and evidence suggests that a key part of the decline occurs in a component of muscle cells called the mitochondria, the primary engine of energy production.

From the study, which was done on men at an average age of 70 years old, researchers reported that “…the older individuals were able to improve strength by approximately 50%, to levels that were only 38% less than that of young individuals…”. This means that seniors engaged in weight training closed the strength gap between themselves and their counterparts who were nearly 40 years younger from 59% to 38%, which is an improvement of almost 36% in a mere six months of the study.

Muscle biopsies from the study showed “a remarkable reversal of the expression profile of 179 genes associated with age and exercise training…Genes that were down-regulated with age were correspondingly up-regulated with exercise, while genes that were up-regulated with age, were down-regulated with exercise.”

The researchers summed things up by reporting that “healthy older adults show a gene expression profile in skeletal muscle consistent with mitochondrial dysfunction and associated processes such as cell death, as compared with young individuals. Moreover, following a period of resistance exercise training in older adults, we found that age-associated transcriptome expression changes were reversed, implying a restoration of a youthful expression profile.”

So when it comes to mitochondria, weight training reversed nearly 40 years of aging!

But exercise doesn’t only affect mitochondria.  Two more studies show how exercise protects DNA from the wear and tear of aging, and how the addition of fast-twitch muscle fibers precipitate fat loss and improve metabolic function – primarily by acting on telomeres.

Telomeres cap the DNA chromosomes in your cells and protect these chromosomes from damage. As you age, telomeres progressively wear and shorten from repeated cell division, oxidative stress, inflammation, and other metabolic processes, eventually leaving the cell’s chromosomes unprotected. When the caps are completely eroded or disappear, the wear and tear begins to cut into your genes, causing cells to become damaged and discarded as you grow older.

In this next study, scientists measured telomeres in twins to gauge the effect of exercise on aging, hypothesizing that “telomere dynamics might chronicle the cumulative burden of oxidative stress and inflammation and, as such, serve as an index of biological age” and that “physical activity level may have an [independent] effect on telomere attrition”.

They studied 2401 twins (2152 women and 249 men, aged 18 to 81), used questionnaires on physical activity level, smoking status, disease status, and socioeconomic status, and extracted DNA from blood samples.

So what did they find in this study on twins?

Telomere length decreased with age. No surprises there. But both the women and men who were physically active had longer telomeres than those who were sedentary, even after adjusting for the influence of age, weight, disease, socioeconomic status, and smoking.

In addition, the study participants who spent more than 3 hours each week engaged in vigorous physical activity (such as lifting weights) had longer telomeres than subjects 10 years younger, suggesting that individuals who eschew placing a vigorous load on their body may wind up biologically older by 10 years.

Obviously, since they were studying twins, these differences weren’t due to genes, but rather due to the lifestyle factor of exercise. When one twin exercised significantly more than the other, they had longer, more durable telomeres.

In the next study, researchers found that replacing slow-twitch type I muscle fibers with stronger and faster type II muscle fibers produced a significant reduction of fat mass and insulin resistance. Endurance training develops slow-twitch fibers, but strength training builds fast-twitch fibers.

For this study, researchers used a genetically engineered mouse that contained a muscle-growth regulating gene called Akt1 that could be turned on and off by the researchers. Activating Akt1 caused the mice to grow type II fibers, without exercise (important to note, since mice don’t really lift weights that well, even when commanded to by scientists in white lab coats). When the Akt1 gene was turned on, the mice took on the characteristics of a lean and powerful sprinter or weight lifter, and when the gene was turned off, the mice reverted to a predominance of type I muscle fibers, along with becoming more obese and insulin resistant (notably, this was without an actual change in diet!).

The researchers reported that “remarkably, type II muscle growth was associated with an overall reduction in body mass, due to a large decrease in fat mass. In addition, blood tests showed that these mice became metabolically normal [with no insulin resistance]. This work shows that type 2 muscle just doesn’t allow you to pick up heavy objects, it is also important in controlling whole body metabolism. It appears that the increase in type 2 muscle fiber orchestrates changes in the body through its ability to communicate with other tissues”.

Beyond the age of 30, we lose approximately six pounds of muscle mass per decade, and these findings indicate that interventions designed to increase skeletal muscle mass (such as weight training) may prove to be critical weapons in the fight against obesity and obesity-related ailments, including diabetes, heart disease, stroke, hypertension, and cancer.

The key point here of course is that weight training, due to it’s recruitment of type II muscle fibers, appears to be more effective than cardio, endurance and aerobics for fat loss, weight control, essentially converting the cells into a fat-burning machine.

Finally, yet another study on strength training effects on telomere length in human skeletal muscle looked into reports of a phenomenon of abnormally short telomeres in skeletal muscle of athletes who had overtraining and exercise-associated fatigue. This important study looked into the question of whether long-term hard exercise might have deleterious effects on muscle telomeres. So, using muscle biopsies, the researchers compared telomere length of a group of power lifters who had trained for an average of eight years against that of a group of healthy, active subjects who had no history of strength training.

There was absolutely no abnormal shortening of telomeres in the power lifters. As a matter of fact, telomere lengths in the power lifters were significantly higher than those of the control group, and telomere length was positively correlated to the power lifters’ individual records in the squat and deadlift!

These results show for the first time that long-term weight training is not associated with an abnormal shortening of skeletal muscle telomere length, and that the heavier the load you put on your muscles, the longer your telomeres will tend to be.

Male birth control shot found effective, but side effects cut study short

Leave a comment

Both men and women are responsible for pregnancy, yet the burden of preventing it often falls on one gender. Women can choose from a variety of options to control fertility while for generations, men have been limited to withdrawal, condoms and sterilization. But someday soon, a new method may allow men to shoulder a greater share of responsibility.

A new hormonal birth control shot for men effectively prevented pregnancy in female partners, a new study found.
The study, co-sponsored by the United Nations and published Thursday in the Journal of Clinical Endocrinology and Metabolism, tested the safety and effectiveness of a contraceptive shot in 320 healthy men in monogamous relationships with female partners. Conducted at health centers around the world, enrollment began on a rolling basis in September 2008. The men, who ranged in age from 18 to 45, underwent testing to ensure that they had a normal sperm count at the start.
The injection, given every eight weeks, consisted of 1,000 milligrams of a synthetic form of testosterone and 200 milligrams of norethisterone enanthate, essentially a derivative of the female hormones progesterone and estrogen referred to as “progestin” in the synthetic form.
According to Dr. Seth Cohen, a urologist at NYU Langone Medical Center, when a man is given a shot of testosterone, “basically, the brain assumes the body is getting enough,” so the body shuts down its own production of testosterone — specifically “the testicle’s production of testosterone as well as the testicle’s production of sperm.”
The progestin “further drives the brain malfunction, so it stops the testicle’s production of both testosterone and sperm,” explained Cohen, who was not involved in the new study.
The researchers used a combination of hormones in order to reduce the testosterone dose to a level that they believed, based on previous studies, would effectively lower fertility yet still be safe.

Study terminated early

During the ramp-up pre-efficacy stage of the study, the couples were instructed to use non-hormonal birth control methods, while the men participants received shots and provided semen samples until their sperm counts dropped to less than 1 million per milliliter in two consecutive tests. At that point, couples relied on the injections as contraception.
Throughout the study, the men provided semen samples to ensure that their sperm counts stayed low. Once the participants stopped receiving the injections, they were monitored to see whether and how quickly their sperm counts recovered to levels described as “fertile” by the World Health Organization.
The researchers discovered that the shot effectively held the sperm count at 1 million per milliliter or less within 24 weeks for 274 of the participants. The contraceptive method was effective in nearly 96% of continuing users.
Four pregnancies (resulting in three live births) occurred among the men’s partners, all during the phase where other contraception was required. All the babies were normal, noted Doug Colvard, co-author of the study and deputy director for programs at the nonprofit research organization CONRAD, Eastern Virginia Medical School, a co-sponsor of the study.
Serious negative effects resulting from the shots included one case of depression and one experience of an abnormally fast and irregular heartbeat after the injections stopped. The researchers considered one intentional overdose of acetaminophen possibly related.
“It is possible that the fluctuations in the circulating progestin following bimonthly injections could haveresulted in the reported or observed mood swings, such as occurs in women, whether on a hormonal contraceptive or not,” Colvard speculated.
Overall, 20 men dropped out early due to side effects. A total of 1,491 adverse events were reported by participants, including injection site pain, muscle pain, increased libido and acne. The researchers say that nearly 39% of these symptoms — including one death by suicide — were unrelated to the shots.
However, due to side effects, particularly depression and other mood disorders, the researchers decided in March 2011 to stop the study earlier than planned, with the final participants completing in 2012.
“I immediately thought of the recent findings on female birth control,” Elisabeth Lloyd said of a study published last month in the journal JAMA Psychiatry. A faculty scholar at the Kinsey Institute, she is a professor of biology and an adjunct professor of philosophy at Indiana University Bloomington.
The study she refers to found an association between the use of hormonal birth control and depression. It looked at prescriptions filled during an 18-year period by more than 1 million women included in Denmark’s national registry.
According to the lead author, Dr. Øjvind Lidegaard of the University of Copenhagen, among women both with and without a psychiatric history who were using hormonal contraceptives, about 10% to 15% got a prescription for an antidepressant during a five-year period.
Annually, the risk of antidepressant use among the youngest group of women taking hormonal contraception amounts to between 2% and 3%. Two or three out of every 100 women between 15 and 19 years old who take hormonal contraceptives will become depressed over the course of a year. “Adolescents seemed more vulnerable to this risk than women 20 to 34 years old,” the researchers noted in their study.
Lidegaard said doctors need to tell women about the benefits and risks of hormonal contraceptive products when deciding which birth control to use.

Effects on fertility

After the men stopped receiving shots, most returned to fertility during a recovery period.
“The minimum recovery time was about 12 weeks after the last injection, and the average time was about 26 weeks,” said Colvard.
Still, there were problems. After 52 weeks in recovery, eight participants had not returned to fertility. The researchers continued to follow these men individually, and five eventually regained normal sperm counts over a longer period of time. One volunteer did not fully recover within four years, though he did “partially recover, so whether he is actually fertile is not known,” Colvard said.
“It shows that it’s a risk, a low-probability risk of it, and it’s not to be sneezed at as a risk of it, surely,” said Lloyd, who is unaffiliated with the new study.
Lloyd said, adding that this risk needs to be compared with those involved in hormonal birth control for women, such as potentially fatal strokes and blood clots.
“These risks of fertility damage are not fatal risks like the women endure with their birth control,” said Lloyd. “You have to compare what women are doing in terms of taking hormones with what men are doing in terms of taking hormones. Are they taking their life in their hands when they take the hormones? Women are. And that needs to be put right up in front when considering the risk.”
Colvard and his co-authors say more research is needed as they work to perfect their cocktail of hormonal contraceptives in an attempt to reduce the risk of side effects, including depression, increased sex drive and acne.
Despite the side effects of the male birth control shot, more than 75% of participants reported being willing to use this method of contraception at the conclusion of the study.
Cohen believes at least part of the reason for this is that they were getting testosterone.

Looking to the future

“Testosterone makes men feel pretty good,” Cohen said. “Testosterone is not a stimulant per se, but it is a steroid, and like a lot of steroids, it can give you a boost of energy. It can give you a boost of muscle mass. It can help with weight loss. It can help with mentation,” or mental activity.
Lloyd believes that if 75% of the men said they’d be interested in getting the shot if it were available, there’s real interest in the product. “That’s unbelievable. That’s fabulous. I’m very very impressed with that number,” she said.
Cohen, who says he he sees patients who face infertility or other hormonal problems, worries about the safety of this method. “Let’s just say, when I read it, I was highly alarmed,” he said, explaining that putting men on testosterone who have normal testosterone levels is not safe and amounts to a violation of the “ethical clinical practice guidelines.”
However, Lloyd thinks this product is a long time coming.
“It’s been a long time since people have been talking about male birth control. This goes back to the 1950s at least.” When scientists first began talking about hormonal birth control for women, they also discussed the same for men, explained Lloyd, but hormonal contraceptives for men were not acted on or investigated.
Cohen questions the general safety of hormonal birth control — for anyone.
“We’re talking about young people, and the scary thing is messing around with young people’s hormones, and that can be detrimental for the rest of their life, right?” Cohen said. “You take an 18-year-old girl or a 20-year-old boy and mess around with their hormones, you’ve really altered possibly how they go through their life.
“If anything, this may wake us up to finding out better hormonal contraceptives for women, right? Because certainly, I know that a lot of young women don’t get the type of counseling that maybe they deserve when it comes to contraception,” Cohen said. “Just a (prescription) and a visit to Duane Reade is all they get, and that may not be enough.”

The Products that Make Men Grow Breasts, Linked to Cancers of the Prostate and Liver

Leave a comment

Owned by Unilever, the Axe brand includes a range of men’s grooming products with many of the ingredients never even tested for safety according to the C.I.R. – Cosmetic Ingredient Review.

Endocrine Disrupting Chemicals

Axe products are loaded with endocrine disrupting chemicals. Endocrine disruptorsare exogenous, synthetic chemicals that have hormone-like effects on both humans and wild-life and interfere with the endocrine system by either mimicking or blocking our natural hormones and disrupting their respective body functions.
Member scientists of the Endocrine Society issued a report in which they claim:

“We present the evidence that endocrine disruptors have effects on male and female reproduction, breast development and cancer, prostrate cancer, neuroendocrinology, thyroid, metabolism and obesity, and cardiovascular endocrinology.”

New studies are also revealing that these harmful chemicals may be causing physical feminization in males. A study published by the International Journal of Andrology found that feminization of boys can now be seen through their play habits.

Medical experts are now wondering whether exposure to years of these toxic chemicals is part of the reason so many older men are low on testosterone and experiencing erectile dysfunction. So they take a little blue pill and get exposed to even more chemicals and the cycle continues.

Aluminum Zirconium Tetrachlorohydrex Gly

Aluminum zirconium tetrachlorohydrex gly is the active ingredient in Axe deodorant products. One or more animal studies show kidney or renal system effects at very low doses, mammalian cells show positive mutation results, animal studies show reproductive effects at moderate doses.

Aluminum was first recognized as a human neurotoxin in 1886, before being used as an antiperspirant. A neurotoxin is a substance that causes damage to nerves or nerve tissue.

 

COCAMIDOPROPYL BETAINE

COCAMIDOPROPYL BETAINE is a very toxic ingredient which has been linked to cancer in animal tests. The biggest danger of using a product with cocamidopropyl betaine is its potential contamination with nitrosamines.

Nitrosamines are created when nitrosating agents are combined with amines.  Nitrosamines have been identified as one of the most potent classes of carcinogens, having caused cancer in more than 40 different animal species as well as in humans.

PPG-14 Butyl Ether

PPG stands for popypropylene glycol, which is made from a completely artificial petroleum product, methyl oxirane. Another name for that is propylene oxide (which is a probable human carcinogen). Propylene oxide is also an irritant and highly flammable. Butyl ethers are in the paraben family, and they are toluene derivatives (toxic petrochemical compounds).  Toluene has proven to have a harmful affect on the reproductive system while parabens have been linked to cancer.

 

PEG-8 Distearate

According to a report in the International Journal of Toxicology by the Cosmetic Ingredient Review (CIR) committee, impurities found in various PEG compounds include ethylene oxide; 1,4-dioxane; polycyclic aromatic compounds; and heavy metals such as lead, iron, cobalt, nickel, cadmium, and arsenic. Many of these impurities are linked to cancer.

BHT

There have been many studies which demonstrate that BHT accumulates over time in the body, having a toxic impact on the lungs, liver and kidneys amongst other negative effects. A study by Gann in 1984 showed that BHT was capable of promoting chemically-induced forestomach and bladder cancer in male rats.

A 1988 Swedish study by Thompson looked at both BHT and BHA. They found that both were toxic and tumour promoting.  Both antioxidants were observed to be cytotoxic in a concentration-dependent manner at concentrations ranging from 100 to 750 microM. At equimolar concentrations BHT was more cytotoxic than BHA.

Low levels of the DHEA prohormone predict coronary heart disease

Leave a comment

Men with low levels of DHEA in the blood run an increased risk of developing coronary heart disease events. The Sahlgrenska Academy study has been published in the Journal of the American College of Cardiology.

The term prohormone refers to the precursor of a hormone. DHEA is a prohormone that is produced by the adrenal glands and can be converted to active sex hormones. While the tendency of DHEA levels to fall with age was discovered long ago, the biological role of the prohormone is largely unknown.

Researchers at Sahlgrenska Academy, University of Gothenburg, have now shown that elderly men with low levels of DHEA in the blood run an increased risk of developing coronary heart disease events.

Lower level – greater risk

The study–which monitored 2,614 men age 69-80 in Gothenburg, Uppsala and Malmö for five years–assessed DHEA levels. The findings demonstrated that the lower the DHEA level at the study start, the greater the risk of coronary heart disease events during the five-year follow-up.

“Endogenous production of DHEA appears to be a protective factor against coronary heart disease,” says Åsa Tivesten, who coordinated the study. “High DHEA levels may also be a biomarker of generally good health in elderly men.”

Clear correlation

According to Professor Claes Ohlsson, “While the study establishes a clear correlation between DHEA in the blood and coronary heart disease, the discovery does not indicate whether or not treatment with DHEA will reduce the risk in individual patients.”

###

“Dehydroepiandrosterone and its Sulfate Predict the 5-Year Risk of Coronary Heart Disease Events in Elderly Men” was published in the Journal of the American College of Cardiology on October 28.

WHAT ALOE VERA DOES IN YOUR BODY: WHY EGYPTIANS CALLED IT THE PLANT OF IMMORTALITY

Leave a comment

Known to the Egyptians as the plant of immortality and to Native Americans as the wand of heaven, aloe vera comes with a wide array of amazing healing properties — some of which you may already be aware. You might even have your own aloe vera plant in your home for those small emergencies like scrapes, cuts, and burns, but did you know that aloe vera is not only limited to topical use and is actually even more beneficial to your body when taken internally?

Aloe vera contains over 200 biologically active, naturally occurring constituents which include polysaccharides, vitamins, enzymes, amino acids, and minerals that promote nutrient absorption.

According to The Journal of Environmental Science and Health, aloe vera also possesses anti-bacterial, anti-viral, and anti-fungal properties that assist the immune system in cleansing the body of toxins and invading pathogens. But that isn’t all aloe vera juice/gel has to offer.[1]

Minerals

Aloe vera has loads of minerals including calcium, magnesium, zinc, chromium, selenium, sodium, iron, potassium, copper, and manganese. These minerals work together to boost metabolic pathways.

Enzymes

Aloe Vera contains important enzymes like amylase and lipase which can aid in digestion by breaking down fat and sugar molecules. One molecule in particular, Bradykinase, helps to reduce inflammation.

Vitamins

One study  showed that aloe vera actually contains vitamin B12, which is required for the production of red blood cells. That would be great news for vegetarians and vegans in particular, who often do not get adequate amounts of B12 through their regular diet. Keep in mind however, that was just one instance and you shouldn’t rely on aloe alone for your daily requirements of b12.

Other studies have shown that taking aloe can assist with the bioavailability of vitamin B12, meaning the body can more easily to absorb and utilize it which can prevent deficiency. Aloe vera is also a source of vitamins A, C,E, folic acid, choline, B1, B2, B3 (niacin), and B6. While it’s tough to say whether we could rely on Aloe as a source of B12, it can be used in conjunction with a supplement to help increase uptake.

Amino Acids

Aloe vera contains 20 of the 22 essential amino acids that are required by the human body. It also contains salicylic acid, which fights inflammation and bacteria.

Other Uses For Aloe

Aside from being an excellent body cleanser, removing toxic matter from the stomach, kidneys, spleen, bladder, liver, and colon, aloe can also offer effective relief from more immediate ailments, such as indigestion, upset stomach, ulcers, and inflammation in the gut. It also strengthens the digestive tract and alleviates joint inflammation, making it a great option for arthritis sufferers.

One study found that aloe vera juice, when taken the same way as a mouthwash, was just as effective at removing plaque as the common mouthwash and its active ingredient, chlorhexidine. This is a much better alternative because it is all-natural, unlike the typical chemical-laden options found in stores.

Aloe vera gel has also been found to effectively heal mouth ulcers, which are more commonly known as canker sores.

How To Take Aloe?

Aloe can be consumed straight from the plant, but the easiest and most palatable option is probably aloe juice, which you can find in most health food stores. You can also buy the leaves from many common grocery stores, or harvest your own, and juice them yourself.

You can buy the juice and mix it into your juices and smoothies or just drink it straight up. Make sure you are buying pure aloe juice/gel which is either of the whole leaf or just the inner filet. It does have a somewhat bitter taste though, so you may want to include other things. On the bottle you can find specific dosing instructions, but it would be wise to talk to a natural health expert or do some research into the matter to find instructions on specific dosing.
