How To Safely Eat Red Meat

If you’re a paleo fan or Atkins diet devotee — or simply a die-hard carnivore — you may be putting your life at risk, a new study reveals.

Eating processed meats like bacon, ham, hot dogs and sausage puts you at risk of getting cancer, according to a report released Monday by the World Health Organization. The WHO put processed meats — defined as meats that have been transformed through salting, curing, fermentation, smoking, or other processes to enhance flavor or improve preservation — in the highest of five categories in terms of their cancer-causing potential, along with cigarettes, arsenic, plutonium and asbestos.

What’s more, the organization says red meat is “probably carcinogenic to humans,” though this was based on more limited evidence. To reach these conclusions, the WHO reviewed more than 800 studies that investigated the association between more than a dozen types of cancer and the consumption of red meat or processed meat in many different countries.

The North American Meat Institute, in a statement issued today, said “scientific evidence shows cancer is a complex disease not caused by single foods and that a balanced diet and healthy lifestyle choices are essential to good health.”

Still, for meat devotees, the WHO report is, no doubt, disturbing. The good news: You don’t have to ditch those meat-filled backyard barbeques just yet.

The main thing you can do to cut the cancer risks of red meat is to eat less of it, as “risk increases with the amount of meat consumed,” Kurt Straif, head of the WHO’s International Agency for Research on Cancer’s Monographs program, notes in the report. The WHO report found that eating just 50 grams of processed meat each day (that’s less than two pieces of bacon) increases the risk of colorectal (bowel) cancer by 18%. For red meat, 100 grams per day (that’s a piece of meat roughly the size of a deck of playing cards) was associated with a 17% increased cancer risk.

So how much is OK to eat? The World Cancer Research Fund recommends that you eat no more than 500 grams (that’s 18 ounces) of red meat a week; that’s about three regular-sized burgers. Harvard Health, a blog published by the Harvard Medical School, recommends that red meat should only make an appearance in your diet only every “now and then,” and that instead, you should eat fruits, veggies, whole grains, beans nuts and seeds each day, along with small portions of cheese, yogurt, fish poultry or eggs each day.

The type of meat matters as well. The WCRF advises that “very little if any” of the red meat you eat should be processed, and the WHO report classifies the processed meats as more dangerous than fresh red meat.

Consumers should also avoid searing their meat at high temperatures, says Jayson Calton, who holds a PhD in human nutrition and co-authored the book “The Micronutrient Miracle: The 28-Day Plan to Lose Weight, Increase Your Energy and Reduce Disease”. This searing, he says, has been shown to cause cancer — a finding that research backs up. (The reason: Two chemicals, heterocyclic amines and polycyclic aromatic hydrocarbons, form on meat cooked at high temperatures, such as when you pan fry or grill directly over an open flame; both have been shown to cause changes in DNA that may increase the risk of cancer.) To avoid this, Calton recommends that you turn down the heat to less than 300 degrees Fahrenheit, turn meat with tongs (since forks can puncture the meat, which causes the flame to flare up), flip meat frequently and avoid overcooking.

There is also some evidence that grass-fed beef has cancer-fighting properties. A study published in the Nutrition Journal, which examined three decades of research on grass-fed versus grain-fed beef, found that grass-fed beef has twice the level of conjugated linoleic acids (which may have cancer-fighting abilities) than does grain-fed beef (as well as a host of other perks like lower levels of unhealthy fats and higher levels of omega-3 fatty acids, vitamins A and E, antioxidants). But despite that, it’s not clear that those perks have much impact on human health.
