The World Health Organization lists 116 cancer-causing agents and activities

The World Health Organization, also known as WHO, has compiled a list of 101 things that can cause cancer -and the list may surprise you.

LOS ANGELES, CA (Catholic Online) - WHO officials claim 50 grams of processed meat each day, which amounts to less than a single breakfast sausage, can increase the risk of colorectal cancer by 18 percent.

The report classified red meat as "probably carcinogenic," but also reported it has nutritional benefits. Though WHO did use the word "probably" in their report, experts have already started to urge the public to avoid processed meats whenever possible and have suggested they substitute a steak salad with a bean salad for a nice amount of protein.

The problem with processed meat is that it has been preserved through various means including smoking, the use of chemical additives, drying and the use of an exorbitant amount of salt.

Experts believe the substances added during processing meats, such as nitrate and nitrite preservatives, is what causes cancer.  WHO categorized fresh red meat a single level below processed meat and described it as being "probably carcinogenic" as well, but fresh red meats also provide a substantial amount of protein, iron and vitamin B12, which can prevent lethargy and infections.

Twenty-two experts from 10 different countries at WHO's International Agency for Research on Cancer reviewed over 800 studies that investigated the links between red meat and processed meat and various different types of cancer.

The cancer linked to red and processed meats is colorectal, or bowel, cancer as well as pancreatic and prostate cancers.

Dr. Kurt Straif, the head of the IARC Monographs Programme, said, "For an individual, the risk of developing colorectal cancer because of their consumption of processed meat remains small, but this risk increases with the amount of meat consumed. In view of the large number of people who consume processed meat, the global impact on cancer incidence is of public health importance."

Dr. Christopher Wild, director of IARC, said, "These findings further support current public health recommendations to limit intake of meat. At the same time, red meat has nutritional value. Therefore, these results are important in enabling governments and international regulatory agencies to conduct risk assessments, in order to balance the risks and benefits of eating red meat and processed meat and to provide the best possible dietary recommendations."
