小心：你喝的水安全吗？

在临床上工作这段时间，我惊奇地发现，在这里有甲状腺问题，特别是甲状腺功能低下的病人出乎意料的多，其中犹于中年女性居多。很多来就诊的患者，即使血液检查数据在正常范围，但也有着很多甲低的临床表现，例如：疲倦、体重不明原因增加、甲状腺肿大、脱发、性欲低下、不孕、四肢发冷等等，这使我觉得非常奇怪。

今天与一个同行，也是我的病人之一讨论这个问题，才知道问题的症结所在。她在临床中也注意到有太多的甲状腺功能异常病人，而她自己也长期受到疲倦、精力不足等问题的困扰（其实我也一样），后来偶然间她发现我们本地用水是经过氟化处理的（fluorinate)。这种情况从1955年开始，至今已有55年之久。于是她开始服用碘剂，各样症状立刻得到改善。

长期以来，人们都只是注意氟化物对牙齿和骨骼的影响，而其对软组织特别是甲状腺功能的影响近年来才引起注意。虽然其作用机制尚在研究中，但有人认为氟化物与氯化物都会严重影响甲状腺对碘的摄取，影响甲状腺素的生成而导致甲状腺功能紊乱。

从上世纪初开始，北美很多地方的用水都是经过氟化处理（而且是用的工业用氟化物），以预防蛀牙，目前有的地区已经停止，有的地区依然使用。想到村中广大朋友的健康，特写此文与大家分享，希望大家最好注意一下当地的生活用水情况（可以查看水费账单或打电话去询问），若是经过氟化处理的，最好多吃海带制品，并去检查一下体内碘的含量，若过低则可适当使用碘剂以增加碘的摄入，以免对我们的健康造成损害。氟化物对儿童的健康成长危害很大。虽然饮用水中的浓度不大，但它会在体内留存，长期摄入在一定程度上会影响人们的健康。

此文并非科学论文，只是一个观察了解，欢迎大家讨论，若有相关资料更加欢迎，因为我准备做进一步的研究了解并加入这里的一个group去说服供水公司将氟从我们的生活用水中去掉。

另附几篇有关氟对人体甲状腺以及身体其它系统的影响的论文，有兴趣者可以查考，谢谢！！

我看有一篇文章,说豆奖已经是转基因食品了,女性吃多了,好象甲状腺也容易出现问题,请看这个:
朋友告诉我美国的豆浆多是转基因的，吃了会引起甲状腺问题。看了他给的链接，实在可怕。似乎黄豆是不能吃的啦！这是其中一段：
Why All Organic Soy is NOT the Answer Either

All of that said, even if you were fortunate enough to find organic soy,
there are still several other significant concerns with unfermented soy
that make it far from attractive from a health standpoint.

Soy contains a number of problematic components that can wreak havoc
with your health, such as:

Goitrogens – Goitrogens, found in all unfermented soy whether it's
organic or not, are substances that block the synthesis of thyroid
hormones and interfere with iodine metabolism, thereby interfering with
your thyroid function.

One common source of soy is soy milk. Many consume it as an alternative
to milk or one of their primary beverages. Soy milk is a significant
contributor to thyroid dysfunction or hypothyroidism in women in the US.

So if you're a woman struggling with low thyroid function and you're
consuming soy milk, that's a giant clue you need to stop drinking it
immediately.

Isoflavones: genistein and daidzein – Isoflavones are a type of
phytoestrogen, which is a plant compound resembling human estrogen,
which is why some recommend using soy therapeutically to treat symptoms
of menopause. I believe the evidence is highly controversial and doubt
it works.

Typically, most of us are exposed to too much estrogen compounds and
have a lower testosterone level than ideal, so it really is important to
limit exposure to feminizing phytoestrogens.

Even more importantly, there's evidence it may disturb endocrine
function, cause infertility, and promote breast cancer, which is
definitely a significant concern.

Drinking two glasses of soy milk daily for just one month provides
enough of these compounds to alter your menstrual cycle. Although the
FDA regulates estrogen-containing products, no warnings exist on soy.

Phytic acid -- Phytates (phytic acid) bind to metal ions, preventing the
absorption of certain minerals, including calcium, magnesium, iron, and
zinc -- all of which are co-factors for optimal biochemistry in your
body. This is particularly problematic for vegetarians, because eating
meat reduces the mineral-blocking effects of these phytates.

Sometimes it can be beneficial, especially in postmenopausal women and
in most adult men because we tend to have levels of iron that are too
high which can be a very potent oxidant and cause biological
stress.However, phytic acid does not necessarily selectively inhibit
just iron absorption; it inhibits all minerals. This is very important
to remember, as many already suffer from mineral deficiencies from
inadequate diets.

The soybean has one of the highest phytate levels of any grain or
legume, and the phytates in soy are highly resistant to normal phytate-
reducing techniques such as long, slow cooking. Only a long period of
fermentation will significantly reduce the phytate content of soybeans.

Natural toxins known as "anti-nutrients" -- Soy also contains other
anti-nutritional factors such as saponins, soyatoxin, protease
inhibitors, and oxalates. Some of these factors interfere with the
enzymes you need to digest protein. While a small amount of anti-
nutrients would not likely cause a problem, the amount of soy that many
Americans are now eating is extremely high.
Hemagglutinin -- Hemagglutinin is a clot-promoting substance that causes
your red blood cells to clump together. These clumped cells are unable
to properly absorb and distribute oxygen to your tissues.

这里有一篇文章，解释得比较全面

谢谢补充，但问题是水中的氟会影响甲状腺对碘的吸收，长期如此则有可能导致甲状腺功能异常。

我的病人几乎70-80都有甲状腺问题，不管是因为什么原因来就诊。这比例实在太高了。

这里还有个体差异，不是每个人都会受影响，如果有症状就去查一下，没有也不必紧张。

你的资料不够全面，牙膏里面也有氟，而影响甲状腺功能很多情况下未必是氟的原因，有很多因素可以影响甲状腺功能，按您的逻辑，这些吃了氟化水地区的人就不应该有甲亢，但事实是，甲亢病人也不少。
只有流行病学调查才能得出正确的结论，需要把饮用氟化水和非饮用氟化水地区的相同年龄、性别、生活习惯（比如使用含氟牙膏、吃碘盐、吃海产品习惯、土地含氟量等等）进行分组，如果发现在这些影响因素相同的情况下，饮用氟化水人群甲低，才能得出您文章的结论。

完全同意你的观点。

我只是说氟会影响碘的吸收而有可能导致甲低，而并未做任何结论，因为如你所说那是要进一步调查才行。

我刚查到一篇文章，请你看看。

http://www.rense.com/general57/FLUR.HTM

There are 141 million Europeans are at risk; only 5 European countries are iodine sufficient. UK now falls into the marginal and focal category. Professor Hume recently produced figures to show that 40% of pregnant women in the Tayside region of Scotland were deficient by at least half of the iodine required for a normal pregnancy. A relatively high level of missing, decayed, filled teeth was noted in this non-fluoridated area, suggesting that the iodine deficiency was causing early hypothyroidism which interferes with the health of teeth. Dare one speculate on the result of now fluoridating the water?

Displaces iodine in the body

These figures would be worrying enough, since they mean that iodine deficiency, which results in hypothyroidism (thyroid hormone cannot be manufactured without iodine) is likely to affect huge numbers of people. What makes it infinitely worse, is that fluorine, being a halogen (chemically related to iodine), but very much more active, displaces iodine. So that the uptake of iodine is compromised by the ejection, as it were, of the iodine by fluorine. To condemn the entire population, already having marginal levels of iodine, to inevitable progressive failure of their thyroid system by fluoridating the water, borders on criminal lunacy.
I would like to place a scenario in front of those colleagues who favour fluoridation. A new pill is marketed. Some trials not all together satisfactory, nevertheless, show a striking improvement in dental caries. Unfortunately, it has been found to be thyrotoxic, mutagenic, immunosuppressive, cause arthritis and infertility in comparatively small doses over a relatively short period of time.

Do you think it should be marketed?
Fluoridation of the nation's water supply will do little for our dental health; but will have catastrophic effects on our general health. We cannot, must not, dare not, subject our nation to this appalling risk.
