Cancer – vegetables and fruit protect it best
The diet influenced the development of cancer – this is today undisputed. Approximately one-third of all cancer cases are related to eating habits. Of course, other factors such as cancer-causing substances from the environment (for example, Smoking), heredity, or infection play a role.
Scientists could now clearly make cancer-causing food ingredients (Carcinogens) such as Benzpyrene in Grilled or black-smoked, as well as aflatoxins in moldy food. In addition, cancer-promoting factors (promoters) were determined, for example, alcohol and cancer protective factors (anti-promoters) such as, for example, Vitamin C. However, no person eats alone of Grilled or Vitamin C. The DGE has therefore examined the question of whether there is a food or diet that can protect disease before the most cancer. These include epidemiological studies about the connection between diet and cancer were reviewed and scientifically evaluated.
A lot of vegetables and fruits, whole grain products and a low-fat diet emerged in this study as the best cancer protective foods. The protective effect of many nutrients and active ingredients are: Vitamin E and C, carotenoids, trace elements (for example, selenium), phytochemicals, and fiber. The exploration of their Anti-cancer effect is still at the beginning. It is very likely that not a single food factors, but their Interaction in the total diet has a protective effect.
Diet and colon cancer
Colon cancer in women in Germany, the second most common cancer in men and the third most common. An estimated 24 000 men and 28 000 women are diagnosed annually. Eating habits are decisive for the emergence of tumors in the colon responsible, but also low physical activity. If you prefer a low-fat diet with plenty of vegetables, fruits, whole grain products and fish and sporty lives, can protect against colorectal diseases. Vegetables – both raw and cooked – of all foods, the best protective effect. Conversely, vegetables haters and lovers of a diet with plenty of grilled or roasted pork, beef and lamb meat of life, as well as with a lot of alcohol, white flour and sugar, may also be a lot of Egg and fat, dangerous. Studies about what kind of vegetable is especially good against colon cancer protects, yet show no clear result. So far, the best protection was determined effect for tomatoes and legumes. Green vegetables and salad seem to be but also effective.
What are the ingredients of the food act protectively or to cause cancer?
This is not yet finally clarified. Dietary fiber from whole grain cereals and carotenoids from vegetables are discussed as potential protective factors. The effect of selenium and Calcium is still controversial. As was shown in a study that a higher intake of Calcium is normalized with a low-fat dairy products, the cell growth rate of the cells of the colon wall. This protective effect is probably due rather to the reduced fat content of the milk. A fat-rich diet promotes may as well as plenty of animal fats (fatty meat, sausages) the emergence of colon cancer. Omega-3 fatty acids from fish and vegetable Oils (e.g. rapeseed oil) have been detected as a potentially protective.
Food ingredients and stomach cancer
Risk factors for diet-related stomach cancer and salt-rich foods (salted meat or fish), as well as the frequent consumption of grilled meat or fish. Protecting a high vegetable and fruit consumption, is likely Vitamin work against C-rich foods and, possibly, also a carotenoid-rich food, whole-grain cereals and green tea. Nitrates, which have been discussed earlier as a trigger, according to recent studies, probably has no effect on the development of stomach cancer. Whether nitrosamines actually increase the risk, needs to be further investigated.
Breast cancer: most common form of cancer in women
Approximately 46 000 women are diagnosed each year in Germany. The development of breast cancer is influenced by many things: predisposition, hormones, the beginning of the menstrual period, age at first pregnancy and birth, as well as nutritional factors. Obesity and increased alcohol consumption the risk of breast cancer is likely to increase; fruit and vegetable – rich diet protects likely. Some scientific studies suggest that a high consumption of red meat (pork, beef, lamb) increases the risk may Vitamin C, carotenoids, and dietary fiber reduce the risk of cancer. This must also be studied, such as the evidence for a protective effect of Vitamin E and certain plant constituents, called phytoestrogens.
DGE-tip: fruits and vegetables for health
Fruit and vegetables protect against all types of cancer, including those that are not considered to be food supported, such as, for example, lung cancer. In all countries in which very much the fruit and vegetables are eaten, these disorders are significantly less common than in Germany, Austria and Switzerland. Therefore, the Council of the DGE is as follows: eat five servings of fruit and vegetables! Source: German nutrition society (DGE)
