Currently, the world's been many different studies on the relation of certain foods or nutrients to increase or decrease the risk of cancer.
The results of studies of cancer cells in the laboratory and in animals sometimes showed that some substances may be carcinogenic (or, conversely, to have antitumor activity).
With a few exceptions, studies on human populations have not yet proved conclusively that any of our food component causes or prevents cancer.
Sometimes the results of epidemiological studies that compared the diets of people with cancer and without them, we showed that people who are suffering and ill oncology, vary in their daily diet power.
However, these results show only that a particular food product associated with a different risk of cancer, but does not prove that this product directly affects the risk of cancer or causes crayfish.
For example, study participants with cancer and without it, may have other more significant among themselves differences, apart from their diet, and it is possible that these differences explain differences in morbidity.
To an epidemiological study proved that the food product is associated with cancer risk, it is necessary to conduct a randomized trial.
This means that the analysis of the relationship of cancer risk and food must be carried out in randomly to take a group of people who They differ in their dietary habits, but do not differ on other risk factors for cancer diseases.
Such studies are very few.
However, scientists and physicians have learned many dietary supplements, nutrients and other food products for possible association with cancer risk.
These include:
acrylamide
Acrylamide - a chemical found in tobacco smoke and various foods.
It can be produced by heating certain vegetables, such as potatoes, to a high temperature (chips, French fries).
Studies in animal models have shown that exposure to acrylamide increases the risk of developing several types of cancer.
However, there is no convincing evidence that the presence of akrilomida in food due to the risk of any type of cancer in humans.
Alcohol
Despite the fact that red wine is suspected of reducing the risk of cancer, there is no scientific evidence of such an association. On the other hand, the alcohol is a known and proven cause of cancer.
Heavy or regular consumption of alcohol increases the risk of developing oral cancer (except mouth), pharynx (throat), larynx (vocal cords), esophagus, liver, breast, colon and direct intestine.

The risk of cancer is directly related to the amount of alcohol that a person consumes.
antioxidants
Antioxidants - are chemicals which block the activity of other chemicals known as free radicals that can damage your cells.
Laboratory studies and animal studies have shown that external antioxidants (Employed in the form of nutritional supplements) can help prevent cell damage associated with the emergence of cancer.
But studies in humans have not yet received convincing evidence that taking antioxidant supplements can help reduce the risk of cancer or prolong the life of those who are already ill.
artificial sweeteners
Safety studies of several artificial sweeteners, including saccharin, aspartame, acesulfame potassium, sucralose, neotame, and cyclamate, found no obvious evidence that these substances are associated with the risk of cancer people.
Calcium
Calcium is an essential trace element of many food products and food additives.
The results of studies generally support a relationship between a higher calcium intake and reduced risk of colorectal cancer, but the results of different studies are not always clearly convincing.
It is unclear whether there is a link between higher calcium intake and reduced risk of other cancers, such as breast cancer and ovarian cancer.
A number of studies have shown that high calcium intake may increase the risk of developing prostate cancer.
Heavily fried meat
Certain chemicals such as heterocyclic amines and polycyclic aromatic hydrocarbons formed when meat, including beef, pork, fish and poultry, prepared using high modes.
These substances are carcinogenic, as confirmed by studies in animals.
However, there is still no conclusive evidence that these factors are the cause of cancer in humans.
Cruciferous vegetables (Chinese cabbage, broccoli, Brussels sprouts, turnip, etc.).
Cruciferous vegetables contain chemical substances known as glucosinolates disintegrating the body for several compounds that have been studied and are being studied as anti-cancer substances.
Some of these compounds showed an anticarcinogenic effect on animal studies, but the results of studies with humans have not yet given a clear answer about their use.
Fluoride
Fluoride (fluorine compound) present in water and help to prevent tooth decay even stop.
Many studies, both in humans and in animals have shown no link between fluoridated water and cancer risk.
Garlic
Some studies have shown that eating garlic can reduce the risk of developing several types of cancer, especially cancers of the gastrointestinal tract.
However, the available evidence and recommendations are not final.
Tea
Tea contains polyphenolic compounds, in particular catechins, which are antioxidants.
Results of epidemiological studies examining the link between tea consumption and cancer risk have been inconclusive.
There have been several clinical trials of tea consumption and cancer prevention, and the results did not show convincing evidence.
An exception should be considered as positive effects of green tea extract to reduce the risk of progression of chronic lymphocytic leukemia.
vitamin D
Vitamin D helps the body absorb calcium and phosphorus for strong bones and teeth.
Vitamin D is produced mostly when exposed to sunlight on the skin but it can also be obtained from some foods and food additives.
Epidemiological studies in humans suggest that higher doses of vitamin D or a higher level of vitamin D in the blood may be associated with a reduced risk of colorectal cancer, but the results of randomized trials are again inconclusive.
