DETROIT -
Processed meat, such as bacon or hot dogs, causes cancer, according to a World Heath Organization group. The group says red meat, including beef, pork and lamb, probably cause cancer, too.
Many studies show the links in tests that show how eating these foods can cause cancer, the International Agency for Research on Cancer (IARC) said in its report, released in the
Lancet medical journa (http://www.thelancet.com/journals/lanonc/article/PIIS1470-2045(15)00444-1/fulltext)l (http://www.thelancet.com/journals/lanonc/article/PIIS1470-2045(15)00444-1/fulltext).
"These findings further support current public health recommendations to limit intake of meat,"
Dr. Christopher Wild, who directs IARC, said in a statement. (http://www.nbcnews.com/health/cancer/processed-meat-causes-cancer-red-meat-probably-does-group-says-n451396?cid=sm_tw&hootPostID=5db16bc862cb07b02964a40872c0cdd4)Most reports on the links between meat and cancer have been softened with some element of doubt, but the IARC uses clear and direct language in saying processed meat causes cancer. There are no phrases such as "may cause" in the report.
"Overall, the Working Group classified consumption of processed meat as 'carcinogenic to humans' on the basis of sufficient evidence for colorectal cancer," the report said.
"Additionally, a positive association with the consumption of processed meat was found for stomach cancer. The Working Group classified consumption of red meat as 'probably carcinogenic to humans'," it added.
"Consumption of red meat was also positively associated with pancreatic and with prostate cancer."
It also defines red meat.
"Red meat refers to unprocessed mammalian muscle meat—for example, beef, veal, pork, lamb, mutton, horse, or goat meat—including minced or frozen meat; it is usually consumed cooked," the IARC said in its report.
"Processed meat refers to meat that has been transformed through salting, curing, fermentation, smoking, or other processes to enhance flavor or improve preservation. Most processed meats contain pork or beef, but might also contain other red meats, poultry, offal (eg, liver), or meat byproducts such as blood."
"The experts concluded that each 50 gram portion of processed meat eaten daily increases the risk of colorectal cancer by 18 percent," the IARC said.

Processed meats - such as bacon, saunited snakesges and ham - do cause cancer, according to the World Health Organization (WHO).
Its report said 50g of processed meat a day - less than two slices of bacon - increased the chance of developing colorectal cancer by 18%.
Meanwhile, it said red meats were "probably carcinogenic" but there was limited evidence.
The WHO did stress that meat also had health benefits.
Cancer Research UK said this was a reason to cut down rather than give up red and processed meats.
And added that an occasional bacon sandwich would do little harm.
Processed meat is meat that has been modified to increase its shelf-life or alter its taste - such as by smoking, curing or adding salt or preservatives.
It is these additions which could be increasing the risk of cancer. High temperature cooking, such as on a barbeque, can also create carcinogenic chemicals.
How bad?The WHO has come to the conclusion on the advice of its International Agency for Research on Cancer, which assesses the best available scientific evidence.
It has now placed processed meat in the same category as plutonium, but also alcohol as they definitely do cause cancer.
However, this does not mean they are equally dangerous. A bacon sandwich is not as bad as smoking.
"For an individual, the risk of developing colorectal (bowel) cancer because of their consumption of processed meat remains small, but this risk increases with the amount of meat consumed," Dr Kurt Straif from the WHO said.
(https://www.abibitumikasa.com/proxy.php?request=http%3A%2F%2Fichef.bbci.co.uk%2Fnews%2F624%2Fcpsprodpb%2F1293C%2Fproduction%2F_86329067_thinkstockphotos-80704773.jpg&hash=ef33932bb8789fa4190c267b88e175d469229873)Image copyrightThinkstock
Estimates suggest 34,000 deaths from cancer every year could be down to diets high in processed meat.
That is in contrast to one million deaths from cancer caused by smoking and 600,000 attributed to alcohol each year.
Red meat does have nutritional value too and is a major source of iron, zinc and vitamin B12.
However, the WHO said there was limited evidence that 100g of red meat a day increased the risk of cancer by 17%.
An eight ounce steak is 225g.
The WHO said its findings were important for helping countries give balanced dietary advice.
Little harmProf Tim Key, from the Cancer Research UK and the University of Oxford, said: "This decision doesn't mean you need to stop eating any red and processed meat, but if you eat lots of it you may want to think about cutting down.
"Eating a bacon bap every once in a while isn't going to do much harm - having a healthy diet is all about moderation."
The industry body the Meat Advisory Panel said "avoiding red meat in the diet is not a protective strategy against cancer" and said the focus should be alcohol, smoking and body weight.
Meat and cancer
There is now a clear body of evidence that bowel cancer is more common among those who eat the most red and processed meat.
The World Health Organisation has classified processed meats – including ham, salami, saunited snakesges and hot dogs – as a class 1 carcinogen which means that there is strong evidence that processed meats cause cancer. Red meat, such as beef, lamb and pork has been classified as a ‘probable’ cause of cancer. These classifications do not indicate the risk of getting cancer, rather how certain we are that these things are likely to cause cancer.
Cancer Council estimates that in 2010, one in six (or 2600) new bowel cancer cases in Australia were associated with consuming too much red meat and processed meat.
Lean red meat can be an important source of iron, zinc, vitamin B12 and protein. In terms of cancer risk there is no reason to cut meat completely from your diet, but there are steps you can take to reduce your risk.
There is not enough evidence to draw any conclusions on eating poultry and the risk of cancer. However, eating fish (http://www.cancercouncil.com.au/1990/get-informed/risk-and-prevention-get-informed/diet-cancer/fish-and-omega-3/?pp=1990) may help to reduce the risk of bowel, breast and prostate cancer.
Meat may affect cancer risk because of chemicals formed during digestion that have been found to damage the cells that line the bowel. Other likely factors include the fat content, and the way it is processed or cooked; or because big meat eaters miss out on other protective foods such as fruit and vegetables (http://www.cancercouncil.com.au/855/get-informed/risk-and-prevention-get-informed/diet-cancer/vegetables-and-fruit/?pp=855) or wholegrain cereals (http://www.cancercouncil.com.au/21775/get-informed/risk-and-prevention-get-informed/diet-cancer/fibre-wholegrain-cereals).
How much meat should I eat?Cancer Council recommends eating only moderate amounts of fresh lean red meat. A moderate intake of meat is 65-100g of cooked red meat, 3-4 times a week. This is also the recommendation in the Australian Guide to Healthy Eating.
Cancer Council recommends people limit or avoid eating processed meats, which are high in fat, salt and nitrates. Because of the high fat and salt content of processed meats, the Australian Guide to Healthy Eating considers processed meats to be ‘discretionary choices’ that should only be eaten occasionally. (Examples of other discretionary choices that should only be eaten occasionally include fast food, cakes, confectionary and chips).
Try to choose lean cuts of meat or chicken, have more fish and make sure you eat plenty of plant-based foods such as fruit, vegetables and wholegrain cereals.
What is a recommended serve?The following are examples of 1 serve of meat:
'"

- ½ cup mince
- 2 small chops
- 2 slices roast meat.

Tips and ideas on meat and low-fat cooking methods'"
n".self::process_list_items("'.str_replace('
', '', '
- Fill half your dinner plate with vegetables and don’t think of meat as the main part of the meal.
- Include at least three different coloured vegetables with your main meal.
- Have some legume-based meals each week. Legumes include lentils, chickpeas, baked beans and red kidney beans. There are many types of dried peas and beans, which can be added to casseroles, soups or salads.
- Buy lean cuts of meat – with the fat trimmed off and little marbling of fat.
- Trim any visible fat off the meat before you cook it.
- Choose chicken pieces without the skin or remove skin before cooking.
- Canned fish like tuna and salmon make an easy sandwich with salad.
- Adapt your recipes to include more vegetables, eg add carrot, celery and peas to Bolognese sauce.
- For stir-fries, reduce the amount of meat and add extra vegetables.
- Experiment with vegetable risottos, frittatas made with vegetables and eggs, hearty vegetable soups or vegetable curries.

| Barbecues and charred meat Some research suggests that burnt or charred meat may increase the risk of cancer. Substances called heterocyclic amines are formed in foods that are cooked at high temperatures and blackened or charred. In animal studies, heterocyclic amines are carcinogenic (cancer causing). However, the evidence in human studies is not clear.It is recommended not to overcook or blacken meat on the barbecue. Marinating meat first prevents foods from charring. As well as keeping potential cancer causing agents down in the meat, marinating also keeps meat tender and adds flavour to your meal. You can also use gentler cooking methods such as casseroling, boiling or microwave heating rather than high-temperature grilling, pan-frying or barbecuing when cooking meat. |
