CDC and ADA Now Advise to Avoid Using Fluoride

[amazon_link asins=’B00006FXPB,B01CDA3A5Q,B01MY0XNZT,B01M3UB8IM,B01N6A7O05′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’06622f52-f59c-11e6-a06f-49d7f942a43e’]

It was 2007 when the American Dental Association (ADA) first warned that parents of infants younger than a year old “should consider using water that has no or low levels of fluoride” when mixing baby formula, due to concerns about fluorosis.

Now the Journal of the American Dental Association has published a study that found increased fluorosis risk among infants who were fed infant formula reconstituted with fluoride-containing water, as well as used fluoridated toothpastes.

A new study in the Journal of the American Dental Association finds once again that, contrary to what most people have been told, fluoride is actually bad for teeth.

Exposure to high levels of fluoride results in a condition known as fluorosis, in which tooth enamel becomes discolored. The condition can eventually lead to badly damaged teeth. The new study found that fluoride intake during a child’s first few years of life is significantly associated with fluorosis, and warned against using fluoridated water in infant formula.

The Centers for Disease Control and Prevention (CDC) is of a similar opinion. According to their website:

“Recent evidence suggests that mixing powdered or liquid infant formula concentrate with fluoridated water on a regular basis may increase the chance of a child developing … enamel fluorosis.”

How Scientific Is Modern Medicine Really?

[amazon_link asins=’0812692896,0763731366,0385720319,0854049290,B06XR81939,B01IUM13K0,B01N2ANRBX’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’1b98d2b6-6f10-11e8-92c6-33832ca25990′]

Doctors today commonly assert that they practice “scientific medicine,” and patients think that the medical treatments they receive are “scientifically proven.” However, this ideal is a dream, not reality, and a clever and profitable marketing ruse, not fact.

CLICK & SEE

John Ioannidis is one of the world’s most important experts on the credibility of medical research. He and his team of researchers have repeatedly shown that many of the conclusions biomedical researchers arrive at in their published studies are exaggerated or flat-out wrong.

However, these studies are what doctors use to prescribe drugs or recommend surgery. Ioannidis asserts that as much as 90 percent of the published medical information relied on by doctors is flawed or incorrect.

The Atlantic reports:
“His work has been widely accepted by the medical community … Yet for all his influence, he worries that the field of medical research is so pervasively flawed, and so riddled with conflicts of interest, that it might be chronically resistant to change — or even to publicly admitting that there’s a problem.”

Further, it is commonly believed that modern medical treatments, including drugs, are “scientifically proven.” In reality, this is a “profitable marketing ruse,” according to a Huffington Post article by Dana Ullman. He reports:

“The British Medical Journal‘s “Clinical Evidence” analyzed common medical treatments to evaluate which are supported by sufficient reliable evidence (BMJ, 2007). They reviewed approximately 2,500 treatments and found:

•13 percent were found to be beneficial
•23 percent were likely to be beneficial
•Eight percent were as likely to be harmful as beneficial
•Six percent were unlikely to be beneficial
•Four percent were likely to be harmful or ineffective.
•46 percent were unknown whether they were efficacious or harmful”

Get Busy if You Want to Beat the Middle-age Spread

[amazon_link asins=’B0011Z76GE,B004CAY21W,B0011Z3CGM,B071D5T5QG,B002UT64W2,006222526X,B00F0TT3A4,B002UT9YVA,B077F4TNZP’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’9115c1bb-def7-11e7-b9c0-956f429daa3e’]

Is there any way to fight the dreaded middle-age spread?

CLICK & SEE
Yes, according to research, the only way to combat the dreaded middle-age spread is to get physical. Many people start gaining a pound a year during midlife — often because they have become less active as they age.

In addition, you start to lose muscle mass at age 40, and will continue to lose more each year unless you take steps to preserve it. This explains in part why many people today suffer from “sarcopenic obesity” — they are overweight or obese and have suffered a progressive loss of muscle mass.

USA Today reports:

“There are people who don’t gain weight, including athletes and people who maintain their physical activity level, eat a healthy diet with plenty of fruits and vegetables and lean protein.”

Avoid Swimming After Exercise to Drop Weight Gain

A study conducted by Australian researchers concluded that cooling off with a dip in the pool after a good work-out may make exercisers more likely to eat than those who don’t go for a swim after exercising.  …..click  & see

According to the Chicago Tribune:

“Test subjects ate more after (two different types of) water immersions than they did after sitting in a chair.

Average calorie intake per person after the cold water immersion was about 489, and about 517 after the tepid water immersion. After resting in a chair, average calorie intake was about 409.

Researchers found lower levels of leptin and higher levels of ghrelin after both water immersion experiments. Following water immersion more carbs and protein were eaten as well.”

Since the study included only 10 participants, researchers suggested that further studies be done with larger sample sizes. The study was published in the Medicine & Science in Sports & Exercise.

Avoid Feeding Your Child Drinking Water contains excessive Manganese

[amazon_link asins=’B00I0ZGOZM,B00HRHHFPW,B01G01T6NO,B003XELTTG,B01G0VIUJU,B00SGGT14Q,B01M0UZUTA,B01N7T81JZ,B00FZ2HAY2′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’1a54cf71-2ce8-11e7-9418-5755786deeba’]

According to a report in Science Daily, a new Canadian study shows that children exposed to high concentrations of manganese in drinking water performed worse on tests of intellectual functioning than children with lower exposures.
CLICK & SEE
The results were published in an article in Environmental Health Perspectives.

While manganese is naturally occurring in soil and groundwater around the world, some of Canada’s groundwater contains an unusually high amount of it, giving the researchers an opportunity to study whether excessive manganese can adversely affect human health.

“We found significant deficits in the intelligence quotient (IQ) of children exposed to higher concentration of manganese in drinking water,” said lead author Maryse Bouchard.

Yet, some areas where lower IQs were reported also registered concentrations below current guidelines. In response to the study, some of the affected municipalities have already decided to install special filtration systems.
