Eating a moderate amount of red or processed meat is associated with an increased risk of colorectal cancer (bowel), according to a
new study
published Wednesday.
People who eat 76 grams of red and processed meat a day – this is consistent with current guidelines and
pretty much the same as a quarter-pound beef hamburger

r –– were 20% more likely to develop colorectal cancer than the others, who ate about 21 grams a day, the equivalent of one
slice of ham
, according to research.
The study also found that processed meat, such as sausages and bacon, was at a higher risk than red meat, with the risk of colorectal cancer increasing by 20% with 25 grams of processed meat (roughly Equivalent of a thin slice of bacon) and 19% with every 50 grams of red meat (a thick slice of roast beef or the edible piece of a lamb chop) .
"A small amount of processed meat seems to have the same effect as a large amount of red meat," said Professor Tim Key, co-author of the study and deputy director of the D & D unit. Cancer epidemiology of Oxford University.
According to the National Health Service (NHS) of the United Kingdom, a slice of ham contains 23 grams of processed meat, while a grilled steak contains 163 grams of red meat.
Cancer Research UK, which partly funded the research, said the current NHS guidelines state that people who consume more than 90 grams (cooked weight) of red and processed meat a day should reduce that number to 70 grams – the amount average consumed per day Britain.
The study, published in the International Journal of Epidemiology, tracked the diet of nearly half a million British adults aged 40 to 69, and their diets were studied over an average period five years. During this period, 2,609 of the participants developed colorectal cancer.
Evidence increasing
This latest research adds to a body of evidence linking red and processed meats to an increased risk of colorectal cancer.
"Our results strongly suggest that people who consume red meat and processed at least four times a week are at a higher risk of developing bowel cancer than those who consume red meat and processed less than two. times a week, "said Key.
He said that previous research had focused on people in the 90s, but that "diets have changed dramatically since then, so our study gives a more current insight that is relevant to meat consumption today." , he said in a press release.
Research has found that alcohol is another factor in increasing the risk of colorectal cancer. The study also indicated that bread fiber and breakfast cereal was linked to a reduced risk of colorectal cancer, which starts in the colon or rectum.
In the United States, it is the third most important cancer, excluding skin cancers, and about
51,020
Colorectal cancer is expected to cause death in 2019, according to the American Cancer Society.
In the United Kingdom, colorectal cancer is the
third most common cancer
in men and women, according to Cancer Research UK.
World Health Organization concluded in 2015
According to the authors of the study, there is sufficient evidence to qualify processed meat as "carcinogenic to humans". the
WHO
classified red meat as "probably carcinogenic to humans."
Dr. Gunter Kuhnle, associate professor of nutrition and health at the University of Reading in the UK, said it was "the largest study ever undertaken in the UK".
Kuhnle, who did not participate in the research, said the findings "confirm earlier findings that consumption of red and processed meat increases the risk of colorectal cancer".
Dr. Julie Sharp, Chief Health Information Officer at Cancer Research UK, said the government's guidelines for red and processed meat are "a general health council and this study is a reminder that more you could reduce your intake, plus reduce your chances of developing bowel cancer. "
She suggests cutting red and processed meat by trying meatless Mondays or chicken and fresh fish recipes.
