    WASHINGTON (Reuters) - People who eat a lot of red meat and processed meats have a higher risk of several types of cancer, including lung cancer and colorectal cancer, U.S. researchers reported on Monday.

    The work is the first big study to show a link between meat and lung cancer. It also shows that people who eat a lot of meat have a higher risk of liver and esophageal cancer and that men raise their risk of pancreatic cancer by eating red meat.

    "A decrease in the consumption of red and processed meat could reduce the incidence of cancer at multiple sites," Dr. Amanda Cross and colleagues at the U.S. National Cancer Institute wrote in their report, published in the Public Library of Science journal PLoS Medicine.

    The researchers studied 500,000 people aged 50 to 71 who took part in a diet and health study done in conjunction with the AARP, formerly the American Association for Retired Persons.

    After eight years, 53,396 cases of cancer were diagnosed.

    "Statistically significant elevated risks (ranging from 20 percent to 60 percent) were evident for esophageal, colorectal, liver, and lung cancer, comparing individuals in the highest with those in the lowest quintile of red meat intake," the researchers wrote.

    The people in the top 20 percent of eating processed meat had a 20 percent higher risk of colorectal cancer -- mostly rectal cancer -- and a 16 percent higher risk for lung cancer.

    "Furthermore, red meat intake was associated with an elevated risk for cancers of the esophagus and liver," the researchers wrote.

    These differences held even when smoking was accounted for.

    "Red meat intake was not associated with gastric or bladder cancer, leukemia, lymphoma, or melanoma," added the researchers, whose study is freely available on the Internet at doi=10.1371/journal.pmed.0040325.

    Red meat was defined as all types of beef, pork and lamb. Processed meat included bacon, red meat sausage, poultry sausage, luncheon meats, cold cuts, ham and most types of hot dogs including turkey dogs.

    Meats can cause cancer by several routes, the researchers noted. "For example, they are both sources of saturated fat and iron, which have independently been associated with carcinogenesis," the researchers wrote.

    Meat is also a source of several chemicals known to cause DNA mutations, including N-nitroso compounds (NOCs), heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs).

    Jeanine Genkinger of Georgetown University in Washington, D.C., and Anita Koushik of the University of Montreal said the findings fit in with other research.

    "Meat consumption in relation to cancer risk has been reported in over a hundred epidemiological studies from many countries with diverse diets," they wrote in a commentary.

  2. I am so shocked by this! I was vegan for 5 years (had to stop for health reasons) but now rarely eat red meat (just chicken and fish). Although I have know about hormones and chemicals in meat this is just appauling.
  3. i read something like this every week. even tofu has been linked to dementia. the key is to have everything in moderation. 2 of my uncles on different sides of my family were vegans. one died from stomach cancer and the other colon cancer. genes play a major role as well as exercise and keeping your weight under control.
  4. boo!!!! what next!!!! :tdown:
  5. first red meat is good for us, and now its not?

    im going to eat whatever i want, we are all not going to live forever anyway
  6. I haven't eaten red meat or pork for years because I don't like the taste. I eat a lot of seafood though.
  7. It's just a matter of not eating a T-bone steak every night. (Well, that's not the best idea anyway, because it's detrimental to heart health.)

    I just stick to skinless chicken (with barbecue sauce).
  8. If my diet don't kill me, the 36 years I've smoked will.

    Gotta die of something.
  9. It's funny how the news will have a story saying that "something" is bad for you and then awhile later, that same "something" is now good for you according to another study.

    Everything is good and then everything is bad... you just can't win... I guess the key is moderation!! (But, I do love a good steak!!)

  10. EXACTLY....people are to eat everything in moderation.
  11. yikes! but they say that they have issues with the chicken over here in Asia more meat for me I guess...
  12. That's right. :drinks:
  13. My great-grandmother lived to be 105. She ate red meat everyday, put butter on everything, and never exercised a day in her life. I'm pretty much banking on the fact that I inherited those genes. ;)
  14. Pretty soon everything we eat will be linked to something.
  15. Just don't eat the pork from that pig farmer in Canada, LOLOL.
