Bacon Causes Cancer

I wonder if that includes the pre-cooked stuff you can get at Costco?

mean we should all become vegetarians?

In an announcement that has alarmed bacon lovers and sent the beef industry into a furor, the World Health
Organization's cancer research arm on Monday declared processed meat a carcinogen, like tobacco, and said red
meat is probably one, too.
Here's what experts have to say about what this new warning means for your diet:
What meats are they talking about exactly?
The International Agency for Research on Cancer's definitions of processed meat and red meat are very
wide. Processed meats encompass any meats that have been "transformed through salting, curing, fermentation,
smoking, or other processes to enhance flavor or improve preservation." This would include sausages, corned beef,
hot dogs, beef jerky, canned meat, meatbased preparations and sauces, turkey and chicken cold cuts, as well as
bacon.
Red meat refers to "all types of mammalian muscle meat," such as beef, veal, pork, lamb, mutton, horse — even goat.
What kind of cancers did the scientists look at?
For processed meat, the carcinogen label was given based on studies about colorectal cancer. They also found an
association between processed meat and stomach cancer. For red meat, the data pointed to associations with
colorectal, pancreatic and prostate cancers.
Why do they think these are dangerous to our health?
Scientists think that something bad happens to meat during the process of salting, curing or other treatment that
causes the build up of carcinogenic chemicals such as Nnitrosocompounds (NOC) and polycyclic aromatic
hydrocarbons (PAH) in the food. In red meat, cooking can also produce suspected carcinogens — in this case
heterocyclic aromatic amines (HAA) and PAH. The IARC's report, published in Lancet Oncology, notes that "hightemperature
cooking by panfrying, grilling or barbecuing generally produces the highest amounts of these
chemicals."
Oh oh. I eat a lot of meat. What do I do now?
The IARC's director, Christopher Wild, said that the group's findings support recommendations to "limit" intake of
meat. But Wild also hedged a bit saying that red meat has "nutritional value."
The American Cancer Society's Susan Gapsur recommends that people who do eat meat begin to cut back on the
amount of red meat they consume and "really limit" their intake of processed meat. Gapsur, a vice president for
epidemiology, said people should be moving toward a more plantbased diet and choose fruits, vegetables, and
beans as alternatives to meat.
Marion Nestle, a professor of nutrition, food studies and public health at New York University, said her
recommendation on processed meat and red meat the same: Eat less. But Nestle stops short of recommending
everyone should become a vegetarian.
"Some people are interpreting it as don’t eat meat at all. I don’t know if that's reasonable," she said. "The evidence
against processed meat is very strong, but it's very hard to consider giving up. A BLT is really a wonderful thing."
She said that a number of the studies that link meat to risk of cancers involve individuals who eat meat
multiple times a week, if not at every meal, rather than occasional consumers of meat. These people may have other
unhealthy habits like exercising less that elevate their risk of cancer. Nestle emphasized that "you don’t need a
special diet for cancer."
"The same healthy diet that is good for heart disease is also good for cancer: a largely—but not necessarily
exclusively—plantbased diet," she said.
That's helpful, but what I really need to know is the bottom line. What's a safe level of meat
consumption? Is it okay for me to eat a hamburger with bacon twice a week? Once a week? Once a
month?
While scientists have come up with those sorts of general recommendation for alcohol consumption (one drink a
day), none exists for meat. A person's individual biology is complex and a safe level for one person may not be safe
for another. It depends on what the rest of your diet looks like, how often you exercise, your genes and a whole slew
of other factors.
U.S. dietary guidelines recommend that Americans eat diets rich in fruits and vegetables, whole grains, seafood,
legumes and dairy and stay away from red meat but they don't offer any specific numbers. The World Cancer
Research Fund International comes the closest — suggesting that people who eat red meat consume less than 500
grams (18 oz) a week and very little if any processed meat.
But American Cancer Society's Gapsur emphasized in an interview that "we don’t know if there is any perfectly safe
level."
"The risk increases with the amount consumed," she said. "The best we can recommend is decreasing your
consumption."
The IARC's report that came out this week says that if you eat 50 grams of processed meat (the equivalent of a few
slices of bacon) every day — or a total of 350 grams a week — your risk of colon cancer goes up by 18 percent. That's
a lot.
