- Delicious carcinogens: These five foods promote disease
- Cancer: the nutrition plays an important role in its formation
- Those are them most harmful foods: Three out of five are animal
Diet plays a crucial role in the development of cancer. An estimated 35 percent of all cancers go back to diet. Every third cancer is caused by excessive The World Health Organization (WHO) estimates that the consumption of unhealthy foods is decreasing. Five products are suspected cancer cells literally to “feed”. These are results of surveys by the authority.
Tasty but carcinogenic: These foods “feed” cancer cells
Research on the subject of nutrition and health keeps coming up new insights. Due to the large number of studies, it is sometimes difficult to keep track. Also, there is some contradicting results.
the Stiftung Warentest categorizes five popular foods suspected of promoting cancer. However, not all of them are clear to what extent they actually promote cancer. For example, the effect of milk is controversial (see below). Still worrying: All five end up on the plate or in the glass of many people every day.
- Processed meat (sausage)
- (Red meat
WHO warns: Certain foods can cause cancer
The WHO is involved worldwide in the fight against cancer. the “International Agency for Research on Cancer” (IARC) the WHO and the “European Food Safety Authority” classify the cancer risks long-term studies a. On this basis, the experts calculate the probability of an illness.
However, they expressly point out that cancer not just through an unhealthy lifestyle can be caused.
A large proportion of the substances considered carcinogenic are not food, but substances that are released elsewhere (e.g. in the chemical industry, in construction or in traffic).
Vegetarian and vegan diet – therefore it prevents cancer
Also family predisposition, previous illnesses or cells mutated by chance lead to a disease. But: “According to estimates, the risk of cancer decreases in people who mainly eat food vegetable origin, by 11 percent,” explains the “WHO”. A meta-analysis of seven studies found that the risk of cancer (all tumor types) about 18 percent lower for vegetarians than the omnivorous comparison groups, according to a scientific article in the Journal of Complementary Medicine.
It goes on to say that at vegetarians (=no meat) compared to meat eaters there was a seven percent lower risk of developing cancer. For tumors of the digestive tract, their risk was 24 percent lower. vegans (=no meat, dairy products and eggs) indicated for aall cancers a 34 percent lower risk of and a 34 percent lower risk of female-specific cancers.
The reason for this is simple: Plant-based diets provide many antioxidants, secondary plant substances and fiber. This counteracts the risk of cancer. Vegetarian and vegan people usually automatically consume more of it.
Delicious and carcinogenic: It is better to avoid certain foods
The IARC shares possible carcinogenic substances in four categories on. In total there will be over 1000 potentially carcinogens categorized by IARC and listed online.
- carcinogenic (1)
- probably carcinogenic (2A)
- possibly carcinogenic (2 B)
- not yet classified with certainty (3)
However, in order to keep the probability of this as low as possible, the scientists recommend avoiding certain foods – including meat, sausage, ham and the like.
1. Processed meat: highest cancer risk level
The results are particularly startling too processed meat: The “WHO” classifies sausage, ham, cured, smoked and salted meat products even on the highest cancer risk level 1 one – and thus on a level with the tobacco smoking. Although the risk of dying as a result of smoking is 175 times higher, processed meat is said to 34,000 deaths to be responsible.
The WHO therefore recommends, if possible little sausage to eat because this promotes cancer formation. “Frequent daily consumption of more than 50 grams can already increase the risk of colon cancer by 18 percent,” it says test.de. The recommendation for red meat is as little as possible up to a maximum of 500 grams per week. So steak and ground beef are also carcinogenic?
The findings of the “International Agency for Cancer Research” are not quite as clear here, which is why Red meat classified as “probably carcinogenic” (category 2A). However, there is also a connection here Colon, pancreatic and prostate cancer possible. According to current assessments, poultry, game and offal are not of concern.
2. Milk: causes and prevents cancer
The results for milk are particularly interesting: While small amounts, i.e. 0.2 to 0.8 liters, can protect against colon cancer, consumption in large quantities is said to increase the risk of cancer. The calcium from dairy products can do that in men Increase risk of prostate canceraccording to the “German Society for Nutrition”.
In women, on the other hand, small amounts of milk may be present breast cancer protection.
One looks in vain for milk on the list of the WHO or the IARC. This does not mean that milk cannot be carcinogenic in certain cases. However, the current research situation does not allow milk to be clearly classified as carcinogenic.
3. Alcohol and Sugar: directly and indirectly carcinogenic
According to the WHO, the influence of alcohol is clearer: “Alcohol in any amount increases the risk of cancer.” The IARC assigns Category 1 alcohol. This means that just complete abstinence eliminates the negative effects of alcohol. However, the more you drink, the higher the risk. It also doesn’t matter which type of alcohol: each is considered a risk factor for various types of cancer in the oral cavity, esophagus, throat, liver, colon and breast.
If you don’t want to do without, you should follow this rule of thumb: women should only have one drink a day and men should have a maximum of two drinks a day, experts advise. A drink is already 0.1 liters of wine or 0.3 liters of beer.
You should be just as economical when consuming sugar, because that too can indirectly cause cancer. “Indirectly” in that it can lead to obesity – and obesity is considered the third-biggest factor in cancer. According to the WHO, the risk of 13 different types of cancer is increased here.
Important here is the body mass index (BMI), a guide value based on height, age and weight. From a BMI over 25, the probability of the disease increases according to the experts.
Conclusion: A healthy diet has a major impact on the development of cancer
It is advisable to follow the recommendations of Stiftung Warentest and WHO, and the only consume small amounts of the foods mentioned or even to remove it completely from the menu. A balanced and healthy diet with lots of fruit, vegetables and legumes makes more sense.
However, the risk of developing cancer can never be completely eliminated. Even if you completely avoid the foods mentioned, do a lot of sport and eat healthily, you can still get a malignant tumor.
