In our daily life, we often see such a phenomenon, two people are at the same age and in the same working environment, but their appearance seems to be more than ten years different. Such a premature aging phenomenon is caused by a variety of reasons, and one of the most important reasons is eating some kinds of food which may easily cause premature senility. Here we will introduce some typical kinds of the foods which may make you grow old much faster.

First, foods containing
Lead will greatly reduce the content of norepinephrine, dopamine and 5-HT in the brain, resulting in nervous conduction block, causing memory loss, dementia, mental retardation and so on. Excessive intake of lead in the body will also directly damage the function of DNA--the genetic material in the nerve cells. It will not only make people easily suffer from dementia, but also will make people look gray and grow old prematurely.

Second, pickled foods
In the process of preserving fish, meat or vegetables, the salt added is easily changed into nitrite. Under the catalytic action of the enzyme in the body, nitrite will easily interact with various kinds of materials in the body, and produce some carcinogens such as imines. If people take in too much imines, they will be more susceptible to cancer and premature aging.

Third, mildewed foods
When the grains, oil, peanuts, beans, meat, or fish become mildewed, they will produce a lot of bacteria and aflatoxin. Once these mildewed materials are eaten by human body, it will cause diarrhea, vomiting, dizziness, vertigo, irritability, enteritis, hearing loss, general weakness and other symptoms. What's worse, it may lead to cancer and premature aging.

Fourth, incrustation
When the tea set or water set have been used for a long time, there will be a lot of incrustation accumulated inside the sets. If it hasn't been cleaned in time, it will cause various diseases in the digestive, nervous, urinary, blood and circulation systems, and thus leading to aging. This is because the incrustation contains a lot of harmful metallic elements such as cadmium, mercury, arsenic and aluminum.

Fifth, alcoholic beverages
Large or frequent drinking liquor in daily life will lead to alcohol poisoning and cause the inflammation and swelling of the liver. What's more, it will result in abnormal sperm, the decline of sexual function and impotence on the men; while women will suffer from irregular menstruation, cessation of ovulation, and some premature aging phenomena such as loss of libido.
