Did you know that fluoride in our water supplies is the only chemical added for a specific medical purpose, i.e. to prevent tooth decay? All other chemicals are added for treatment purposes, to improve the quality and safety of tap water. And an expert has voiced his concerns over the potential negative impact of fluoride in drinking water on the health of fetuses and infants.

Dr Vyvyan Howard is a medical pathologist and toxicologist, and also President of the International Society of Doctors for the Environment. In a short video clip put together by the Fluoride Action Network, he expressed his concern over the use of fluoride in our water supplies.

About Dr Howard

Over the last two to three decades, Dr Howard's research has centered on the effects of toxic substances on the development of fetuses and infants. This, of course, is a period of life whereby one is particularly vulnerable to certain external effects.

So, how was Dr Howard's attention first drawn to fluoride? According to him, it was the "very very low levels" of the chemical found in human breast milk. This, he said, is due to a mechanism developed in the course of evolution, specifically for keeping the substance away from developing infants.

"Nature has devised a system for keeping fluoride away from the infant, and we are circumventing that by putting fluoride into drinking water, and I think there are consequences," he said.

What consequences? According to Dr Howard, fluoride is a developmental toxin. More specifically, it is a neurotoxin, and it may also affect the intelligence of the child. While the evidence may not yet be clear-cut, there do seem to be strong indications.

Further, Dr Howard said that other studies have shown the possible ability of fluoride to affect hormonal systems and endocrine systems. In particular, it can influence thyroid levels, and that can have an impact on the IQ in children who are in the development phase.

When thyroid levels are measured in the mother, being at the upper limit of the normal range of thyroid and being at the lower limit of the normal range brings about a difference in intelligence in the offspring. Where thyroid levels are concerned, we are thus "tinkering with quite a sensitive system".

About Water Fluoridation

Should fluoride be added to our water supplies? Dr Howard was quite clear about what he felt.

"So, the evidence is out there for us to have to say that we got to be very careful. And my opinion is that there isn't a satisfactory one dose fits all solution through treating our population via tap water. There are going to be some members of that population which will be more disadvantaged than others, and they will obviously include the fetus and the infant, but at the other end of life, people who have got marginal kidney function will be more susceptible. And therefore, I don't think, on a precautionary basis, that we should be continuing the fluoridation of drinking water supplies," he said.

And he had some strong words regarding the authorities who continue adding fluoride to water supplies, too.

"If governments don't have ways of making sure that people in the areas that are fluoridated who are susceptible, like bottled fed babies, are actually stopped from being exposed in that way, then they have no right, really, to be using a mass medication like this," he added.

According to the video clip, Dr Howard is one of over 1,750 professionals from various communities - medical, scientific, and environmental - to sign a statement "calling for an end to water fluoridation worldwide".

Worried about the Teeth?

There may be some of us who are worried about how removing fluoride from our drinking water might affect our teeth. But we may not need to be.

An increasing number of studies have cast doubts on the benefits which water fluoridation can bring to the teeth. According to statistics from the World Health Organization, the tooth decay rates of countries which do not fluoridate their water supplies are just as low, or even lower, than those countries which do.

Further, several studies published since 2000 have reported that there has been no increase in tooth decay rates noted in communities which ended water fluoridation.

And we should also note that, in November 2006, the American Dental Association actually advised parents to avoid giving fluoridated water to babies.

Babies who are exposed to fluoride have a higher risk of getting dental fluorosis, which is a permanent tooth defect arising when fluoride damages the cells which form the teeth.

Fluoride's benefits result from topical contact with the teeth, and swallowing or ingesting it brings minimal benefit. According to the Centers for Disease Control and Prevention, fluoride's "predominant effect is posteruptive and topical". Posteruptive means "occurring or forming after eruption (as of the teeth)".

Removing Fluoride from Our Water

In fact, ingesting fluoride comes with many health risks. Besides affecting the brain and the thyroid gland, the bones and kidneys can also be negatively impacted.

For those of us who are genuinely concerned about our health, and especially the health of our little ones, removing fluoride from our drinking water is imperative.

Unfortunately, unlike for chlorine, boiling does not do the trick. An installation of a reverse osmosis filter, or carrying out of water distillation, may thus be necessary.

你知道，在我们的自来水中添加氟化学为了医疗目的，即防止蛀牙？所有其他化学品是增加了xx目的，以提高质量和安全的自来水。并有专家表示了对潜在的负面影响的“氟”，饮水对胎儿和婴幼儿的健康问题。

霍华德博士Vyvyan是一个医学病理学家和毒物学家，也是国际的医生学会会长环境。在一个短片提出的氟化物联系在一起，他表示他对食水供应的氟化物的情况表示关注。

关于霍华德博士

在过去二，三十年间，霍华德博士的研究曾就对胎儿和婴幼儿发展中的有毒物质影响的中心。这当然是一个生命的宽限期，即一个特别容易受到某些外部影响。

因此，医生是如何霍华德首次提请注意氟？据他介绍，这是“非常非常低的水平化学”在人类母乳中找到。这一点，他说，是由于在进化过程中形成一种机制，专门为来自发展中国家的婴儿保持物质以外。

“大自然已制订了不让婴儿的氟以外的系统，我们绕开以为把成饮用水氟，我认为有后果，”他说。

什么后果？据霍华德博士，氟化物是一种发育毒素。更具体地说，它是一种神经毒素，它也可能影响儿童的智力。虽然证据可能尚未明确，但这样做似乎是强大的迹象。

此外，医生霍华德说，其他研究显示可能的氟化物能影响xxx系统和内分泌系统。特别是，它可以影响甲状腺的水平，而且可能对儿童的智商谁在开发阶段的影响。

当甲状腺水平衡量的母亲，是在甲状腺正常范围上限，在正常范围的下限是一名在情报的后代带来的差异。如甲状腺水平而言，我们因此“与一个颇为敏感的系统的修修补补”。

关于水加氟

如果氟化物加入我们的水供应？霍华德博士很什么，他感到清楚。

“因此，证据就在那里我们必须说，我们到了必须非常小心。而我的看法是，没有一个令人满意的一剂适合通过自来水处理通过我们的人口的解决办法。将有是人口将会比其他弱势的一些成员，他们当然会包括胎儿和婴儿，但在生命的另一端，人们谁也得到边际肾功能将更加容易。因此，我不'吨认为，在预防的基础上，我们应该继续实施饮用水供应的氟，“他说。

和他有强烈的话谁有关当局继续加氟水供应，也。

“如果政府没有作出肯定的是，在氟谁很容易受到如瓶装喂养的婴儿，地区的人们，实际上是阻止暴露方式以这种方式，他们没有权利，真的，将使用像这样大规模的xx，“他补充说。

据视频剪辑，霍华德博士是1,750多来自不同社区的专业 - 医学，科学和环境 - 签署一项声明，“一个全球水氟呼吁结束”。

对牙齿担心？

有可能是我们中的一些谁担心如何xx香港水氟会影响我们的牙齿。但是，我们可能不需要。

一个越来越多的研究投下的好处是在水中加氟可以给牙齿疑虑。据世界卫生组织，国家的蛀牙率不加氟的水供应统计数字只是为低，甚至更低，比不少国家。

此外，一些研究公布自2000年以来报告说，已经没有蛀牙率上升注意到在社区，在水中加氟结束。

此外，我们也应当看到，在2006年11月，美国牙医协会实际上是建议家长避免让婴儿含氟水。

谁接触到氟宝宝有氟斑牙的获得较高的风险，这是一个{yj}性的牙齿缺损时因氟化物破坏了细胞构成的牙齿。

氟的好处，从局部与牙齿接触的结果，吞咽或摄入带来最小的好处。据美国疾病控制和预防中心，氟化物的“主要作用是posteruptive和专题”。 Posteruptive意味着“爆发后发生的或（如牙齿的）”形成。

从我们的氟化物去除水

事实上，摄入氟附带了许多健康风险。除了影响到大脑和甲状腺，骨骼和肾脏也受到负面影响。

对于我们这些谁是真正关心健康的人群，特别是我们的小孩子的健康，xx饮用水的氟是必不可少的。

不幸的是，不同的氯，把水烧开也不可能成功。一个反渗透过滤器，或进行水蒸馏出来的安装，因此可能是必要的。
