Vitamins and
minerals can help us to defend ourselves from the everyday stresses and
disturbances that lead to deadly and degenerative diseases. Minimum dose that
prevent the emergence of deficits are much higher than officially set dose,
especially for those vitamins that protect the body from stress and
environmental pollutants that day because we are increasingly exposed.
Because of
that increase occurred degenerative diseases such as cancer and cardiovascular
disease, compared to the past. In addition, there are many environmental and
health circumstances that require a greater amount of certain vitamins and
other food ingredients to help the body be protected and if they do not provide
that amount comes to the deficit. These circumstances include stress, exposure
to hazardous and noxious substances, dealing with severe mental and physical
labor, sports, older age, pregnancy, lactation, and many diseases such as
diabetes, cancer, infection, heart disease, vascular diseases and surgical
procedures .
Studies show
that vitamin A stimulates virtually all cells of the body's defense system,
protects the body against viruses and bacteria, neutralizes toxins, stimulate
the body's defense system and has a direct impact on many types of cancer. The
reason is not only that it improves the work of many defensive cells, sometimes
up to 60%, but also affects the proliferation and differentiation of cells in
the presence of tumors and cancers poremećeno.Veza between vitamin A and cancer
was discovered in the 1926th when a team of scientists found that in laboratory
animals leads to gastric cancer if fed food that lacks vitamin A.
Consuming
extra vitamin A can prevent pretkarcinogenih and cancer cells. It has been
found that people who do not have enough vitamin A in the body bear several
times higher risk of developing tumors. The reason why the use of vitamin A in
the treatment of cancer has not spread is its relative toxicity when
administered in large doses. However, it should be noted that people with
cancer are much more tolerant of large amounts of vitamin D than healthy
people.
Niacin
therapy can also prevent or significantly reduce the occurrence of cancer,
especially in the secondary, which occurs after the initial cure rate using
chemotherapy. The people who consume niacin in higher doses than recommended
occurrence of primary cancer was also reduced.
In the
treatment of cancer and vitamin B6 proved useful, and then folic acid. The
research results show that folic acid may protect against some cancers and even
therapeutic value. There is a positive proportional relationship between the
status of this vitamin in the body and cervical cancer, and colorectal.
That is why
this vitamin sometimes used in medical practice and prevention of cancer. The
doses given are usually very large, but folic acid is not toxic, so there is no
risk of negative side effects.
Exposure to
harmful substances in the workplace can cause harmful changes in chromosome
structure and thus lead to an increased risk of cancer. When workers exposed to
halogenated ethers provides vitamin C, the rate of destruction of their
chromosomes is significantly reduced. This example applies to the coal miners.
Ascorbic acid or vitamin C is good antimutagenic agent.
Nitrosamines
present in processed foods, and also present in cigarette smoke are
carcinogenic. Vitamin C prevents their formation. Epidemiological studies have
shown that the occurrence of cancer in the digestive system directly
proportional relation with the amount of nitrite levels in food and drinking
water. In some countries, vitamin C is added to cured meats to prevent them in
the formation of harmful nitrosamines.
It was
estimated then that smokers should consume at least 1000-3000 mg of vitamin C
per day to meet the basic needs for this vitamin. vitamin C protects the body
by participating in the formation and maintenance of collagen and the body's
defense system. Ascorbic acid readily creates combinations with some metals and
thus actually ejected from the circulation and the body. Thereby reducing the
amount of lead, mercury, nickel and vanadium, which are very harmful.
In the
treatment of some forms of cancer also applies to D vitamin . Proved to be
effective in preventing some forms of metastatic lung cancer and prostate
cancer. A good vitamin D status is also inversely proportional linked with
breast cancer and colon cancer.
Vitamin E
effectively prevents the formation of some rises and their activity in the
body, especially of breast cancer because it improves the poor relationship between
progesterone and estradiol, two important hormones in the body. Although
vitamins are not drugs, it appears that their presence in the body is
sufficiently significant impact on slowing down the development of some of the
most malignant diseases of today.
