Meat and sausage: harmless enjoyment or risky temptation?

Meat and sausage: harmless enjoyment or risky temptation?

Meat and meat products supposedly cause colon cancer. Are sausages and nuts harmful? We looked at the facts.

Question: Does regular consumption of red meat or processed meat increase the risk of colon cancer?
Answer: probably that
explanation: People who regularly eat a lot of red meat or processed meat products such as sausages, ham and bacon will probably be less likely to have colon cancer than people who eat less meat.

Sausages, nuts and pork chops are among the favorite Austrian dishes. However, meat and meat products encourage colon cancer. The background is an overview of WHO World Health Organization in 2015 [4].

Processed meat products, such as smoked or cured meat products, WHO is classified as unique "Causes of Cancer" he; For example, it means sausage, ham and bacon. Red meat – all meat except poultry – is called "Possible Carcinogenicity" text.

But what is the danger? Medizin- Transparent.at investigated.

Risk increased slightly

It is likely that a diet rich in fiber increases the risk of colon cancer. This is not just about the analysis of the WHO in 2015. A recent review, summarizing the results of the previous studies, comes to this conclusion. [1]People who regularly eat a lot of meat in these researches have become more sensitive to colorectal cancer than those with low meat diet.

Is meat consumption associated with other types of cancer can not be answered in the review article. The combined results of other studies, however, show that meat lovers die before people who hardly consume meat [2].

Cancer risk in numbers

How high the risks are, the authors calculated the European survey. As a result, the risk of cancer increases by 12 percent with each additional daily serving of 100 grams of red meat (beef, pork, lamb, goat, game) [1]But what does it really mean in numbers?

Men in Austria daily consume 140 grams of red meat and meat products [7].
With this average diet (140 grams per day), 35 out of every 1,000 males develop colon cancer throughout their lives [6].
For men who eat more than 100 grams of meat (240 grams a day), 39 out of every 1000 suffer from colon cancer throughout their lives.
On the other hand, if they eat 100 grams of less meat a day (40 grams a day), 31 out of every 1,000 will suffer from colon cancer.
The daily extra of 100 grams results in a difference of 4 cancers per 1000 males.

Women are less likely to develop colon cancer than men [6], In Austria women eat 70 grams of meat and meat products daily [7].
At this average diet (70 grams a day), 21 out of every 1,000 women develop colon cancer throughout their lives [6].
If you eat 100 grams of meat a day (170 grams a day), between 23 and 24 out of every 1000 will develop colon cancer throughout your life.
For every additional 100 grams daily, the difference is 2 to 3 cancers per 1000 women.

Something more for processed meat

For sausages, ham, bacon and other smoked, dried or otherwise processed meat products, the risk of colon cancer is slightly higher. Combined results of previous studies show that the likelihood of colorectal cancer increases by 17 percent from every 50 g of additional share [1].

Awarded to the Austrian population means additional 50 grams of processed meat per day:
In men, instead of 35 of 1,000 Austrians, 41 out of every 1,000 would develop colorectal cancer during their lifetime.
In women, instead of 21 out of 1,000 Austrians, 25 out of 1,000 would develop colorectal cancer during their lifetime.

Vegetarianism as the only option?

How large is the average amount of meat, which increases the risk of colon cancer, study analysis [1] do not answer.

Whether total abstinence can further reduce the risk of cancer, the analyzed studies have not been investigated [1], The authors investigated only two groups: those with the lowest and those with the highest consumption of meat.

As medicine has already reported transparently (see Vegetarian Life: Healthier Without Meat?), Vegetarians are less inclined to get cancer and cardiovascular disease than people who eat meat. It is unclear whether a poor diet of meat is associated with a higher risk of colon cancer than full diet.

Risk factor among many

Although it is likely: clear evidence that meat or meat products are causing cancer, previous research results, despite all probabilities [1] does not deliver. Because there are other explanations that can imagine that more meat consumption is associated with increased risk of colon cancer.

For example, people who eat a lot of meat are less inclined to look after their health than those who occasionally consume meat. They may already have a relatively large health burden, for example because of unfavorable income and the situation in education. For example, the risk of colon cancer has increased in people with severe weight, moving or drinking a lot of alcohol [8].

If known, such factors can be taken into account in nutritional studies and calculated from the results. That is not always possible. In addition, other unknown risk factors may affect the results of the research.

Prevention of colon cancer

The risk of colon cancer increases with age. Colon cancer is very rare in persons younger than 50 years, and most are older than 75 years. About two out of three people with this diagnosis can cure cancer [9].

Colon cancer has developed over many years since the precursor, so-called. Intestinal polyps. Intestinal polyps are common, occurring in about one third of adults over 55 [9]However, most warts never produce cancer.

One way of preventing colon cancer or having a low-priced early detection scan is – even if you feel healthy and there are no objections. By using a chair or colonoscopy test, polyps or cancer are early recognized and can be early removed [9].

More information on colon cancer and its early detection methods is provided by the independent portal portal health information.de.

More detailed studies

For a system overview [1] The German-Austrian-Belgian research group wanted to find out how big the risk of colon cancer is actually the result of red meat and processed meat (sausage, ham, bacon, etc.). In April 2017, they sought all the studies that were published so far [1].

In total, 31 cohort studies were found. For these studies, researchers initially interviewed a large number of healthy volunteers about their eating habits. They then noticed how many participants in the next few years had colorectal cancer. At the end of the study they compared: Was it among the people who, according to their own information, ate a bit of meat, they rarely came to cancer but among those who often ate meat?

The results of these cohort studies finally complied with the authors of the meta-analysis. It became clear that the risk of colon cancer increases with the amount of consumed meat.

To be sure, they only analyzed those studies that were very high quality for comparison – with the same robust score.

Since the review is very well done, we evaluate that the results are reliable. As mentioned above, studies can not prove that colon cancer actually benefits from high meat consumption. Since cohort studies can never rule out that other unknown factors are the real cause of the disease.

WHO gap analysis

WHO published a short version of the study's study in 2015 [3]However, this did not have any important details to understand the conclusions of the World Health Organization. Therefore, we could not use this paper for our assessment. 2018 followed a detailed long version [4], But even in this, there is too little information to be able to clearly understand the choice of analyzed studies.
