Filthy ate no scientific basis for disease in do?

A number of studies have shown that fewer children living in rural areas suffer from allergies, asthma and eczema and other diseases. This may be because they have a greater chance of exposure to toxic substances. Cats, dogs and other pets, children who appear to have stronger resistance.

"Hygiene hypothesis" can also be explanations of the reasons for the rising risk of cancer.


　　Filthy to eat to be disease -　Have some scientific basis for


Everyone knows that we should pay attention to keep clean, but the excessive pursuit of clean and healthy may be harmful to human health. This theory is what scientists call "hygiene hypothesis." British "Daily Mail" 21 days, scientists now believe that "hygiene hypothesis" may explain why the incidence of cancer is now the British 70 years than in the mid-20th century, an increase of 25%.


　　The more clean, the easier it is allergies?


There is a saying that the early exposure in life a certain amount of bacteria and dust will start the body's immune system against threats to prepare for the future.


It is reported that last year, reached the British to buy cleaning products total 610 million pounds, the spending in the past five years, an increase of 16%. But supported the "hygiene hypothesis," who says, keen to cleaning a result of the rising risk of allergies. Data show that the British are the world's high level of risk of allergy, with an average of about 6,000 people each year due to a serious animal allergies, bee bites, food allergy treatment.


In addition, a number of studies have shown that fewer children living in rural areas suffer from allergies, asthma and eczema and other diseases. This may be because they have a greater chance of exposure to toxic substances, or drinking unpasteurized milk containing the bacteria. Cats, dogs and other pets, children who appear to have stronger resistance.


　　Exposure to bacteria could be cancer?


Scientists believe that "hygiene hypothesis" can also be explanations of the reasons for the rising risk of cancer. According to the theoretical hypothesis, constant contact with allergens, bacteria or certain toxins the immune system can always maintain a high degree of vigilance, so that early stage in the formation of cancer cells to be curtailed.


There are numerous examples of bacteria against cancer, "New Scientist" magazine has reported that the 20th century 70's, it was discovered that cotton textile practitioners risk of lung cancer than other industries. The researchers believe that the mystery of a cotton and carry dust pollution, bacterial toxin can stimulate the immune system on high alert.


Some experts believe that if put in a few weeks after birth and send them to nursery school, children are unlikely to have contracted leukemia among children. Because in the nursery, the babies cough, drooling, sucking, they are formed by the immune system has been placed in an environment containing a variety of bacteria. In this way, the immune system is always in an active state, the body resistance is enhanced. But experts point out that a year old, the infant immune system reaction to the bacteria become too strong. Leukemia Research Foundation Clinical Expert Kenkanbeier said: "If the first contact with bacteria too late, but will greatly increased risk of disease."


Campbell also stressed that "hygiene hypothesis" is applicable to cancer treatment has not been confirmed. He cautioned parents, or should be adopted to maintain a clean living environment, prevention of childhood leukemia
