Dr. Oz Proves This Fruit Juice Can be Toxic


Inorganic arsenic, the form most likely to cause cancer, occurs naturally in the earth and is released into ground water that travels through rocks and soil. The U.S. Environmental Protection Agency (EPA) limits the amount of trace arsenic allowable in drinking water to 10 parts per billion (ppb).
However, arsenic has also been found in other drinks and foods, for which no safety limit has been set, raising concerns about overexposure through the diet.

Juices and Foods Tainted with Arsenic

This past summer, the U.S. Food and Drug Administration (FDA) announced a "voluntary suspension" of the arsenic-laced drug Roxarsone, which has been widely used on chickens raised in CAFOs (Confined Animal Feeding Operations) to control an intestinal parasite.
More recently, an investigation into arsenic and lead levels in apple- and grape juice prompted Consumer Reports to call for government standards to limit consumer exposure.
Ten percent of the 88 juice samples tested by Consumer Reports had arsenic levels exceeding the U.S. federal drinking-water standard. A quarter of them also had lead levels higher than the 5 ppb limit set for bottled water.
"The investigation included an analysis of the National Center for Health Statistics' National Health and Nutrition Examination Survey (NHANES) database from 2003 to 2008.
The results of that analysis suggest that these juices may be an important contributor to dietary arsenic exposure.
Through interviews with physicians and authors of peer-reviewed studies, Consumer Reports also found mounting scientific evidence suggesting that chronic exposure to arsenic and lead even at levels below federal standards for water can result in serious health problems, especially for those who are exposed in the womb or during early childhood. FDA data and other research reveal that arsenic has been detected at disturbing levels in other foods as well.
… In addition to juice, foods including chicken, rice, and even baby food have been found to contain arsenic -- sometimes at higher levels than the amounts found in juice ..."

Vitamin D rejuvenates aging eyes in laboratory study


Vitamin D rejuvenates aging eyes in laboratory study

Friday, January 20, 2012. An article published online on January 2, 2012 in the journal Neurobiology of Aging reports an eye-rejuvenating benefit for a short course of vitamin D supplementation in aged mice.

Professor Glen Jeffery and his associates at the Institute of Ophthalmology at University College London supplemented old mice with vitamin D3 for six weeks while an untreated group served as controls. In addition to improved vision, the team found a reduction in number and changes in the configuration of retinal macrophages—immune cells that can sometimes cause excessive inflammatory damage—in animals that received the vitamin, as well as a decrease in retinal amyloid beta accumulation, which is a marker of aging. In humans, inflammation and amyloid beta accumulation are associated with an increased risk of age-related macular degeneration, a leading cause of blindness.

"In the back of the eyes of mammals, like mice and humans, is a layer of tissue called the retina," explained Dr Jeffery. "Cells in the retina detect light as it comes into the eyes and then send messages to the brain, which is how we see. This is a demanding job, and the retina actually requires proportionally more energy than any other tissue in the body, so it has to have a good supply of blood. However, with aging the high energy demand produces debris and there is progressive inflammation even in normal animals. In humans this can result in a decline of up to 30% in the numbers of light receptive cells in the eye by the time we are 70 and so lead to poorer vision."

Scoliosis Exercises - New Concepts Involving Training The Brain May Have Impact


Scoliosis exercises come in many shapes and sizes, however very few of them are worth the time and effort when it comes to this complicated spinal condition. Many attempts to treat an "idiopathic" (unknown cause) condition would be a frustrating experience for the patient and physician alike and treatment for Idiopathic scoliosis is no exception. For literally thousands of years, doctors, religious leaders, and the various "wise men" of the day have attempted to "crack the scoliosis treatment code" without success.
Devices that provide artificial correction of the spine have been developed and used since the beginning of recorded history and the first metal scoliosis brace was developed in 1575. To date, none of these devices have been able to reduce the steadily increasing rate of scoliosis surgery, nor alter the natural course of the condition.
Attempts to surgically "correct" idiopathic scoliosis have been utilized since 1865 and, while having improved dramatically since that time, still remain a highly invasive procedure with many complications and a poor long-term success rate.

10 Diets That May Do More Harm Than Good


Trying to shed that beer gut? Want to fit in to that little black dress? Be it hundreds of pounds or just a few ounces, most people are trying, in some form or fashion, to shed some extra weight. The formula is simple: the number of calories taken in should be less than the calories out. Couple that with a healthy lifestyle that includes plenty of water and some exercise, and almost anyone can look and feel great. Unfortunately, some people are willing to try anything. Whether it's gorging on Twinkies or swallowing sleeping pills, dangerous diets abound. Often nutrition deficient — or just plain weird — these weight-loss plans can do much more harm to the body than good. These ten diets are ones you shouldn't try, and after reading this list, probably won't want to.
  1. THE CIGARETTE-POPCORN-WHISKEY DIET

    In his 2006 autobiography, My Life In and Out of the Rough, be-gutted PGA golfer John Daly lost 65 pounds in less than a year on a diet of cigarettes, popcorn, and whiskey.
    Why It Works: Dieters, rejoice! Drunkenly smoking and snacking on the golf course for ten hours a day is exactly the cure for the woes of your weight! Completely deficient in nutrients of any sort, this diet of corn, air, and potentially deadly toxins could be just the ticket to a sexy new you.
    Drawbacks: Cancer. Life-wrecking addiction problems. Decreased golf course prowess. DWIs. Jail. Probable death.
  2. THE TWINKIE DIET

    Sounds too good to be true, right? Believe it or not, this diet has gained some widespread media attention. After a nutrition professor ate nothing but processed, sugary foods for ten weeks and lost 27 pounds, eyebrows raised worldwide about the Twinkie diet.
    Why It Works: The diet was originally performed as an experiment in basic mathematics. If the number of calories burned is higher than the number of calories consumed, weight loss is possible and will occur.
    Drawbacks: Processed foods are fake foods; they contain many preservatives and chemical elements that do not occur naturally in fresh foods and, in large quantities, could be harmful to the body. Plus, Twinkies taste good, powdered donuts even better. Limiting yourself to a net caloric deficiency could be nearly impossible, especially for those with a sweet tooth.
  3. THE CABBAGE SOUP DIET

    An extremely popular liquid diet, the cabbage soup diet has been around for decades. Every soccer mom and potential supermodel you know has likely gone through a "cabbage soup" phase. On this plan, dieters eat mostly cabbage soup (obviously), and are promised to shed several pounds quickly.
    Why It Works: This diet is essentially a liquid diet, and is highly restrictive in terms of calorie intake. This diet is only designed for short term weight loss goals, and usually only lasts for about a week.
    Drawbacks: All you eat is cabbage soup. Dieters essentially lose only water weight, and usually gain back their losses shortly after ditching the plan. Theyalways ditch the plan.
  4. THE MASTER CLEANSE

    This diet is perceived to be highly popular with celebrities as a means of detoxing their bodies and shedding those few extra pounds that they probably didn't have in the first place. As such, the Master Cleanse diet has received lots of press, both good and bad. Essentially, the dieter drinks a concoction of lemonade, cayenne pepper, and maple sugar, and foregoes most other forms of sustenance.
    Why It Works: This diet is a liquid-only diet that creates a calorie deficit in its adopter, as well as spurring loss of water weight. If it worked for Beyonce, it'll work for you, right?
    Drawbacks: Doing a Master Cleanse usually involves lots of talking about doing a Master Cleanse. Be prepared to annoy your friends and loved ones, and be reliant on celebrity news outlets for tips and tricks on how to starve yourself with spicy lemonade.

When is Scoliosis Surgery Necessary?


To date, the bulk of the information you will find related to Adolescent Idiopathic Scoliosis (AIS) on the Internet supports the use of back bracing and scoliosis surgery. Initially, treatment from a medical doctor consists of "observation only", until the Cobb angle progresses to 25 degrees, at which point the patient is placed in a scoliosis brace. When back bracing is unsuccessful in stabilizing the progression of the disease, which is frequently the case, scoliosis surgery is the only other option that the medical community has to offer.
Due to the complicated nature of idiopathic scoliosis and the difficulty in understanding and treating this condition, the development of a surgical method of treating idiopathic scoliosis by Dr. Harrington was understandable. However, science, & long term research agree that this procedure does not cure idiopathic scoliosis, but rather replaces one deformity (a flexible, curved spine) with another (a straighter, fused spine).
A majority of people we see, who have been treated with scoliosis surgery, report after the operation that their pain levels either stayed the same or worsened, leading to long term use of stronger and stronger pain medication. "On average, 16 years after surgery, 40% of surgery patient are permanently handicapped for the rest of their lives" (Long-term results of quality of life in patients with idiopathic scoliosis after Harrington instrumentation and their relevance for expert evidence. Gotze C, Slomka A, Gotze HG, Potsl W, Liljenqvist U, Stienbeck J. Z Orthop Ihre Grensgeb 2002 Sep-Oct, 140(5): 492-8).

Surgical Techniques Affect Outcome in Scoliosis Surgery


For patients with adolescent idiopathic scoliosis, eight factors correlate significantly with maintenance of kyphosis, according to a study published online Jan. 5 in Spine.

(HealthDay News) — For patients with adolescent idiopathic scoliosis (AIS), eight factors correlate significantly with maintenance of kyphosis, according to a study published online Jan. 5 in Spine.
Baron S. Lonner, M.D., from the New York University Hospital for Joint Diseases in New York City, and colleagues investigated the surgical and radiographic factors in AIS surgery that affect kyphosis maintenance, in a retrospective multicenter study of 269 patients. Participants had kyphosis of less than 22 degrees. Operative data were recorded, and a complete radiographic series was obtained for each patient before surgery, immediately after surgery, and at two years after surgery.
In multivariate analysis, the investigators found that maintenance of kyphosis at two years post-surgery was significantly associated with eight variables. Increased kyphosis at follow-up correlated significantly with anterior approach, elevated thoracic coronal curve, and a greater percentage of hooks in the construct. Hypokyphosis correlated with a larger number of levels fused, preoperative kyphosis, the percentage of screws in the construct, use of stainless steel rods, and percent decrease in the thoracic curve.
"Our multivariate analysis demonstrates that in patients with AIS who have thoracic hypokyphosis as part of their deformity, anterior approach, fusing as few levels as possible, and using a hybrid construct are associated with improved thoracic sagittal contour," the authors conclude.
The study was supported by corporate/industry funding; one or more authors disclosed financial ties to a commercial entity related directly or indirectly to the study.

Neck pain study reinforces use of chiropractic, other conservative options


January 6, 2012 — A new studypublished this month in the Annals of Internal Medicine finds spinal manipulative therapy (SMT) and exercise more effective at relieving neck pain than pain medication. The research reinforces the use of conservative care options like chiropractic as a first line of defense against pain, according to the American Chiropractic Association (ACA).

The study divided participants into three groups that received either SMT from a doctor of chiropractic (DC), pain medication (over-the-counter pain relievers, narcotics, and muscle relaxants) or exercise recommendations.

After 12 weeks, about 57 percent of those who met with DCs and 48 percent who exercised reported at least a 75 percent reduction in pain, compared to 33 percent of the people in the medication group.

After one year, approximately 53 percent of the drug-free groups still reported at least a 75 percent reduction in pain; compared to just 38 percent pain reduction among those who took medication.

The study also found that despite experiencing limited pain relief, people in the drug group continued using a higher amount of medication more frequently throughout the follow-up period. This finding underscores concerns raised in an April 2011 government report that indicated prescription drug abuse in the U.S. has reached crisis level.

"Doctors of chiropractic have long cautioned against the overuse of medication to treat musculoskeletal pain," said ACA President Keith Overland, DC. "We continue to promote drug-free, conservative interventions for neck pain patients before referral for medical management that may result in side effects. Patients deserve to know that there are natural, drug-free options when it comes to pain relief."

Why you should eat more (not less) cholesterol


For decades now, the general American population has been neurotically avoiding cholesterol-rich foods for fear of developing heart disease, thanks to the promulgation of the unfortunate Diet-Heart hypothesis. (1)
Those of us that follow a paleo diet are well aware by now thatdietary cholesterol does not significantly affect cholesterol levels in the blood or risk for heart disease, and that there is no reason to avoid whole foods with naturally high levels of cholesterol.
However, beyond just ‘not avoiding’ high cholesterol foods, there is a significant reason for us to make a special effort to include many high cholesterol foods in our diet.

Exercise May Encourage Healthy Eating Via Brain Changes

Exercise may encourage healthy eating by changing parts of the brain that influence impulsive behaviour, according to a new review of the available literature by researchers from Spain and the US published in Obesity Reviews. The researchers conclude that in a society where we are surrounded by temptations and triggers that facilitate over-eating and excess, the part of the brain responsible for "inhibitory control" undergoes "relentless strain" (they note it has limited capacity anyway), and doing exercise on a regular basis enhances it. 

"By enhancing the resources that facilitate 'top-down' inhibitory control, increased physical activity may help compensate and suppress the hedonic drive to over-eat," they write. 

Obesity has been rising at an alarming rate in Spain in recent years, so much so that in some parts of Spain, the proportion of the population that is obese is higher than that in many parts of the United States, the country traditionally considered as having the highest obesity rates in the western world. 

Also, in line with other countries in the Mediterranean, Spain has one of the highest rates of childhood obesity in Europe.
