Fluoride Decreases Bone Strength


Community water fluoridation has long been touted as a safe and effective means to reduce dental caries in a population, yet data on the long-term safety of low levels of systemic fluoride exposure on the myriad of body systems are either inconclusive or completely lacking. Ingested fluoride is incorporated into the bones, suggesting that exposure over a lifetime, even to the relatively low levels experienced via fluoridated water, may affect the structural or mechanical properties of bone. Chachra et al. (2010) compared bone specimens from residents of fluoridated Toronto to those of non-fluoridated Montreal, with the hypothesis that these populations would reveal patterns consistent with differences in long-term fluoride exposure. The fluoride content of bones from the fluoridated area was significantly higher than those from the non-fluoridated area. Bone from Toronto residents showed greater mean strain at ultimate compressive stress (UCS, an indicator of fracture risk) and greater energy absorbed to failure than bone from Montreal residents. However, the authors failed to control for age, which was greater for those residents in non-fluoridated Montreal. Bones typically weaken with age, and thus the effects of a more elderly population in Montreal may have obscured the full effect of fluoride on the Toronto population. A more relevant finding is that UCS and yield stress declined with increasing fluoride content of bone, indicating that bone strength decreases with increasing bone fluoride level. While similar animal studies have been performed, this is the first human epidemiological study to utilize such an analysis to study fluoride levels and risk of bone fracture, and thus should be seriously considered by public health officials when performing evidence-based risk assessments for fluoride exposures for the whole of the population.

Prevent Illness Before it Hits Home



With kids going back to school, most parents know that this means more colds and flu- likely for everyone in the household. So just how do we arm our children with the best means to protect themselves from these pesky germs?

The key to keeping kids healthy as they head back into the classroom is to bolster their immune systems. By re-balancing their immune systems to a normal and natural state, they will be more likely to fight off any pesky invaders they come in contact with.

Germs spread quickly and easily in classrooms because kids tend to touch each other and communal objects—toys, balls and desks—often, and then bring their hands back to facial openings such as their mouth, nose and eyes. If germs are present, this is how they enter the body.

The first line of defense is teaching children to avoid hand-to-face contact. This may work with older children who tend to be somewhat less spontaneous, but with younger ones this is not always practical.

According to naturopathic physician Dr. Dick Thom of the BambĂș Clinic in Portland, Oregon, there are a number of key steps that should be implemented to keep kids at their peak health.

One of the primary considerations is to eliminate any food allergies or sensitivities that the child may have, since they continuously put stress on the immune system without parents or the child even being aware this is happening. The most commonly undetected sensitivities are to foods such as dairy, wheat, corn, soy and even fruits such as oranges.

To help support a strong immune system, children should regularly consume a fish oil supplement. Dr. Thom recommends the use of quality cod liver oil, as it contains both the essential fatty acids (Omega-3 fatty acids) and vitamin D, which research is showing most North American children are deficient in. Vitamin D is a key player in immunity.

Probiotics, or good bacteria, are also vital to the body's ability to protect itself. These beneficial bacteria help to fight infection by stimulating the body's ability to create antibodies—our defense against harmful bacteria and viruses. Probiotics can be found in specific cultured and fermented foods, including some yogurts, as well as in supplement form.

In terms of lifestyle, sleep is often an undervalued need. A large number of today's children are not sleeping properly and thus are not able to give their bodies the time and rest they need to fully recuperate. Adding insult to injury, they often wake up late and then skip breakfast, later turning to sugary foods to give them an artificial energy boost. Dr. Thom believes this extra sugar encourages hypoglycemic reactions in the body, which further weakens immunity.

Regular exercise also helps. Exercise stimulates the movement of lymph fluid in the body. Lymph fluid contains lymphocytes—vital white blood cells that fight illness-causing pathogens—making it an active part of the immune system. Cardio exercise of any kind keeps lymph circulating, enabling the immune system to perform better.

When your child does fall ill, Dr. Thom believes the best remedy is to support your child's body in its quest to heal itself. That means lots of rest, liquids such as water and homemade soup, and if desired, Epsom salt baths.

"The best is to not to give children anything, especially something to lower a fever," says Dr. Thom. "A fever is the best defense the body has to fight infections. Everyone worries about febrile seizures but research shows they are not a problem."

By following some of these sensible and effective strategies for keeping your child healthy, you can take some of the stress out of the back to school season. And as we all know, an ounce of prevention really is worth a pound of cure.

Dr. Boyd adds that the article overlooked the importance of a healthy spine and nervous system free of interference. Your body knows what to do... the brain controls all the systems of the body and sends its instructions to the other systems of the body and those systems in turn send information back to the brain, telling the brain what they are doing. It is when there is nervous system interference caused by subluxation or misalignment or vertebra that cause the body dis-case and not to function at 100% that lowers our immune system and that is when we get run down, tired and sick.

He is right on the mark about not giving anything to lower a mild fever. Diseases invade our body when we get run down and they like to live at 98.6 degrees. So our immune system naturally raises our body temperature to fight off and kill these invaders. Parents don't like to see their kids sick and want to do something to help them feel better so they might give a fever reducer but as we have seen, that inhibits the bodies own natural defense mechanism and can actually lengthen the child's illness. One colleague of mine said, "under 103 bring them to me 104 out the door"; so 103 hold tight and keep your kids cool and comfortable and hydrated, at 104 it's time to consult your pediatrician.
