The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruits and green vegetables. It is only when people try to live on a very restricted diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins.
An example of the dangers of a restricted diet may be seen in the disease known as “beri-beri”, which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted（传播）by a germ（病菌）. He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain. It was thought this would be easier for weak and sick people to digest.
Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients’ plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain.
Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice（糙米）somehow prevented or cured beri-beri — even that a lack of some ingredient（成分）in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.

Doctors have known for a long time that extremely loud noises can cause hearing damage or loss.The no
ise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little mire than one second to be affected.
An American scientist has found that using aspirin (阿斯匹林) increase the temporary (暂时的)hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great.
The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise.

A new survey finds that more than eighty percent of Internet users in the United States search for health information online. The survey found that searching online is one of the leading ways that people look for a second opinion though doctors are still the main source of health information.
Forty-four percent of people are actually looking for doctors or other providers when they search for health information online. Another finding of the survey: Two-thirds of Internet users look online for information about a specific disease or medical condition.
The Internet has also become an important source of emotional support for people with health problems. Susannah Fox says one in five Internet users has gone online to find other people who have the same condition. It was more popular among people with more serious health issues—one in four people living with chronic diseases (慢性病). And it was basically off the charts with people living with rare disease. They are so eager to find other people online who share their health concerns.
A disease is considered rare if it affects fewer than two hundred thousand people worldwide. The rise of social networking has made it easier for people with rare diseases to connect with each other and feel less alone. Social networking is also changing the way some doctors and patients communicate with each other. Dr. Jeff Livingston operates a medical center for women in Irving, Texas. His office uses password-protected software to share information with patients.
“We provide the patient full access to their medical care. Anything I can see, the patient can see. All of their notes, all of their doctor visits are right there. All of their lab work is right there.” Dr. Livingston says the software has increased efficiency, reduced costs and improved relations with patients.
