Brazil nuts are rich in selenium

Selenium reduces the risk of bladder cancer:

When analyzing the nails nearly 121,000 adults, Dutch scientists accidentally discovered that a diet rich in selenium help prevent bladder cancer. This effect is particularly evident in those who smoke.

While blood tests only reflect the content of mineral salts into the body in the near future, the hidden nails contain information about the minerals are absorbed from long before that. Measured the concentration of selenium in the toenails.

They found that many user groups most selenium reduction was 1 / 3 bladder cancer risk compared with use of this material at least. In particular, if the object were former smokers, the risk of bladder cancer decreased by 70%.

The previous study showed that high levels of selenium may reduce the risk of lung cancer, colon and prostate.

Selenium supply is important for the body as meat, fish, cereals, dairy products and eggs. Some nuts, especially Brazil nuts, are also rich in selenium.

Anthrax bacteria:

Sending anthrax through the mail is not easy?

To be able to instilling anthrax in the mail, first of all, people have grown than spores. Then be dried and crushed into fine powder. This powder must be fine enough to be inhaled into the bottom of my lungs. Another important thing is to preserve the activity of bacteria.

This is a very difficult task, even for professionals experienced microbiology. In most cases, bacteria often become useless after the last stage of "processing".

Each day, firefighters in the Hialeah, a suburb of Miami, received an average of 20 calls reported about the possibility of being attacked by anthrax bacteria.

Since the early weeks, many public buildings or commercial establishments have been evacuated, after detecting the envelope containing white powder believed to be biological weapons by terrorists sent.

Millions of Americans are obsessed with the question: People can get anthrax by mail are not? Experts agree that this is possible but very difficult technically. The implementation must be very experienced and are prepared very meticulously.

However, the question how the anthrax back to the AMI building, where the victim worked, remains unsolved.

Normal blood pressure is not ... normal

Need to monitor blood pressure regularly:

A recent study of U.S. shows, in the subjects blood pressure is considered normal, people with this index in the high-normal (above the normal threshold) or cardiovascular disease than the 1.5

* 2.5 times higher than those with optimal blood pressure.

By definition, people with high blood pressure over 140/90 mmHg is considered high blood pressure. Among those with normal blood pressure, we distinguish:

* Optimal blood pressure: 120/80.

* High-normal blood pressure: 130-139/85-89.

Research conducted on 7,000 people during 10 years showed that high-normal blood pressure is susceptible to heart attacks, heart failure and stroke than those with optimal blood pressure. This causes people to rethink the definition of hypertension. Can be selected current threshold is too high.

Although no clinical trials have shown that high-normal blood pressure will lead to lower risk of heart disease, doctors believe that lifestyle changes can help these people improve health, prevent problems related to blood pressure and not using antihypertensive drugs.

Improvement in lifestyle including weight loss (through diet and exercise), reduce salt intake and alcohol consumption in moderation. A further measure is also quite effective fat loss, increased vegetables, fruits, protein and some other important minerals.
