吃富含鎂食物 或可防中風

路透紐約16日電）1篇涵括約25萬名對象的國際分析研究指出，食用許多綠葉蔬菜、堅果和豆子等富含鎂食物的人較不容易中風。
不過這篇刊登於「美國臨床營養雜誌」（AmericanJournal of Clinical Nutrition）上的研究報告作者，並未建議人們每日攝取含鎂營養品，因為研究分析聚焦於食物中的鎂，而且可能是這些食物的另一個成分與研究發現有關。
研究報告主筆、瑞典斯德哥爾摩的卡洛林斯卡研究所（Karolinska Institutet）教授拉森（SusannaLarsson）說：「從飲食攝取鎂的量，和中風風險成反比，特別是缺血性中風。」
她說，研究結果建議人們攝取「綠葉蔬菜、堅果、豆子、五穀雜糧等富含鎂的食物」。
拉森和同事爬梳過去45年研究資料庫，找出調查研究對象攝取多少鎂，並追蹤他們多年後中風情形的相關研究。
過去14年發表的7篇研究，追蹤美國、歐洲和亞洲約25萬人平均11.5年。其中約3%研究對象在追蹤期間內中風，即約6500人。
1個人每天只要多攝取100毫克鎂，缺血性中風風險就下降9%。缺血性中風是最常見的中風，血塊為典型病因。
根據分析，美國公民每天平均攝取242毫克鎂。美國建議超過31歲男女每天分別攝取420毫克、320毫克鎂。中央社（翻譯）

抗生素永久破壞腸道菌群平衡

發表於 2012 年 01 月 16 日 由 nnadmin

過度使用抗生素已經廣泛被認為是促使抗藥性超級細菌出現、破壞腸道益菌且因此造成消化等健康問題的元兇；現在一項新的評論又指出，腸道益菌的破壞甚至可能是永久性的。

紐約大學朗格尼醫學中心 (Langone Medical Center) 的馬丁‧布萊瑟教授 (Martin Blaser) 一直在研究抗生素對腸道益菌的長期影響，並且已經證實抗生素與消化系統中的益菌瓦解有關。這項研究似乎還證實了這些干擾可能是永久性的 (至少對於一些人而言)，會造成終生的健康問題。
布萊瑟教授在評論中表示，在其實驗室中早期的證據已經顯示受到破壞的腸道益菌將不會完全恢復，這些體內益菌長期的改變甚至可能增加受到感染和疾病侵 擾的可能性。過度使用抗生素將可能促使肥胖、第一型糖尿病、腸胃炎、過敏及氣喘等病症的發生率大幅增加，而且可能增加不只 1 倍。
布萊瑟教授建議當務之急應該是限制幼童及懷孕女性過度使用抗生素的現況，因為這可能是造成新生兒體內益菌較過去減少的主因。如果抗生素確實是造成一些人體內腸道微生物永久性失衡的原因，這些人可能需要終生補充益菌，以維持正常健康的益菌平衡。
現在，大幅減少所有年齡層使用抗生素是當務之急，特別是幼童及懷孕女性。養殖業使用生長激素及抗生素也應該一併禁止，因為最終這些肉類都會成為人類每天食用的產品。

The Link Between Processed Meat and Cancer

Mike Barrett
Activist Post

A recent study conducted by Swedish researchers has shown a further link between processed meats such as sausage or bacon and an increased risk of pancreatic cancer. This kind of connection is not necessarily new, but the study provides further evidence that indulging in processed meats may not be the greatest decision for your health. 

Processed Meats Increases Pancreatic Cancer Risk

The study, published in the British Journal of Cancer, analyzed data from 11 clinical trials which involved 6,643 individuals struck with pancreatic cancer. What they found was that eating processed meats such as bacon, sausage, salami, pepperoni and hotdogs increases your risk of developing pancreatic cancer by 19 percent for every 50g of processed meat consumed. What may sound startling is that you only need to consume one sausage to meet the 50g.

Processed meats are those preserved by smoking, curing or salting, or using chemical additives. What makes the meats so problematic is the nitrates which are added for preservation such as coloring and flavoring. The nitrates are converted into nitrosamines, which have been linked to a number of cancers.

Although the research calls for the reduced consumption of processed meat, this is only one more reason to avoid processed meats altogether. Many processed meats increase your risk of diabetes, negatively impact lung function, and increase your risk of chronic obstructive pulmonary disease.

Processed meats have also been shown to increase your risk of:

• Colon cancer by 50 percent
• Bladder cancer by 59 percent
• Stomach cancer by 38 percent
• Pancreatic cancer by 67 percent

Of course processed meats aren’t the only thing to look out for. Foods which have undergone processing measures will seldom be found in a healthy selection of foods. What may interest you is the fact that fatty processed foods have been shown to trigger addiction and lead to brain damage, which is one explanation as to why people want so much of them. In fact, growing evidence finds processed foods and sugary drinks are as addictive as cocaine.

The solution? Simply limit your consumption of processed meats and processed foods in general. It may seem difficult, as these foods have probably been around your entire life.  However, making this necessary change will not only dramatically improve your health, but also prove that you have the power and self-control to make what may seem like a drastic change to your diet.

Can Fluoride Calcify Your Arteries?

Sayer Ji, Contributing Writer
Activist Post

New research reveals a startling new finding: fluoride is likely contributing to the epidemic of cardiovascular disease by stimulating calcification of the vascular system, including the coronary arteries.

In a study published in the journal Nuclear Medicine Communications this month (Jan. 2012), researchers assessed fluoride uptake and calcification in the major arteries of 61 patients who were administered sodium fluoride, the active ingredient in most fluoridated toothpastes. The study revealed:

"The coronary fluoride uptake value in patients with cardiovascular events was significantly higher than in patients without cardiovascular events."

They also found that there was a significant correlation between fluoride uptake and calcification observed in most of the arterial walls, indicating that the fluoride itself likely stimulates the precipitation of calcium within the arteries.

It is already well-known that vascular calcification is highly correlated with cardiovascular disease mortality. The hardening of the arteries associated with atherosclerosis is in part due to the calcification of plaque which subsequently becomes brittle and susceptible to breaking off into an artery-obstructing clot.

Even taking elemental calcium supplements (sourced from limestone, bone meal or oyster shell), at doses as low* as 500 mg a day, was shown in two meta-analyses last year to increase the risk of heart attack by up to 27%.

What is novel about this new study is that it indicates how cardiovascular calcification may be occurring. Beyond the excessive consumption of inorganic calcium, fluoride may be an essential factor in mediating calcium's contribution to enhanced cardiovascular morbidity and mortality. Fluoride exposure is now ubiquitous, thanks to the fluoridation of public drinking water, medications like Prozac (fluoxetine), non-stick cookware, to name but a few common routes of exposure.

Fluoride-induced calcification is not a new finding. Back in 2001, autopsies on cadavers revealed that fluoride accumulation in the pineal gland is associated with enhanced calcification of that endocrine organ. 

GreenMedInfo.com contains research on natural substances which may attenuate Fluoride Toxicity and Ectopic Calcification.

*The National Osteoporosis Foundation, whose corporate sponsors include elemental calcium supplement manufacturers Oscal and Citracal, recommend 1200 mg a day for women over 40.

Revealed: Doctors Routinely Cheating Exams in Uncovered Scandal

Anthony Gucciardi
Activist Post

Utilizing an extensive data bank of answers recorded by those who have taken the test, radiology doctors around the nation from prestigious and little-known programs alike have been cheating the exam system for a very long time.

With exam officials openly admitting that the cheating has been going on for a ‘long time’, the information sheds light on the fact that many radiology doctors may actually be completely unqualified to be dosing up patients with damaging radiation.

Doctors around the country have setup very complex banks of information known as ‘recalls’, which have been setup by doctors who have previously memorized test questions and shared them for public viewing.

With each question meticulously documented and archived by radiology residents, the answers cover just about every program in the county — including the highly prestigious.

This system makes even the most respected exam completely worthless in determining the knowledge base of the doctors. 

Extensive Cheating Puts Unqualified Doctors in Control of Your Health

The cheating is so widespread that even the executive director of the American Board of Radiology (ABR) has brought the issue to the public eye. As an overseer of the exam that certified the radiologists, Dr. Gary Becker expressed his knowledge of the ongoing cheating process that has existed for years:

'It’s been going on a long time, I know, but I can’t give you a date,' said Becker. 'We would call it cheating, and our exam security policy would call it cheating.'

What’s more is that radiology residents taking the test actually are required to sign a document agreeing not to share material on the test, but the report shows that the document is widely ignored. In fact, when interviewed by CNN dozens of radiology students stated that they promised fellow residents to write down the questions from the tests immediately. These are the doctors that are responsible for dosing up children with ‘safe’ levels of radiation.
