Science: Beef Good, Bacon Not So Bad

A new European study claims an increase in processed-meat consumption raises the risk of early death. But the real news? Red meat won't kill you.

Earlier this month, researchers announced the results of a big new nutritional study in Europe that seemed to yield more evidence that processed meats like bacon and sausage can lead to an early grave. The media responded with the usual "Death by Salami" headlines. What news outlets downplayed about the study, though, is that despite their best efforts, the EU researchers couldn't find any evidence that red meat will kill you. In fact, the study shows that not eating red meat is a risk factor for an early demise.

After correcting some measurement errors, the researchers in Europe had to conclude that not only was red meat intake "no longer associated with mortality" but "all-cause mortality was higher among participants with very low or no red meat consumption."

The government, public health advocates, and the American Heart Association have long warned Americans that overconsumption of red meat can lead to heart disease and other ailments. Yet the scientific evidence supporting this hypothesis has always been weak. And in fact, this month's study isn't the first to fly in the face of these assumptions. A large study in Japan also found no increase in heart disease deaths from moderate meat consumption as well.

And last year, Harvard researchers published another similar large study. The media reporting on the study declared that researchers had found that "adding an extra portion of unprocessed red meat to someone's daily diet would increase the risk of death by 13%. The figures for processed meat were higher, 20% for overall mortality." But the Harvard data also showed that meat consumption had a protective effect for a lot of people. Up to a certain point, people who ate more of it fared better than those who ate little or none. The source of some of this confusion is simple: People who eat junk food are unhealthy in myriad ways that make it nearly impossible to zero in on a single food item as the source of their health woes.

To see what I mean, let's take a closer look at the EU study. Known as the European Prospective Investigation in Cancer and Nutrition (EPIC), it included more than half a million people from 10 European countries who were queried on a host of different factors, from how much and what they ate to their levels of education, their age, their weight, and whether they'd ever smoked. The study indicated that people who eat a lot of processed meats are also more likely to smoke, eat few fruits and vegetables, and have lower levels of education. They're much fatter and exercise less than the rest of the sample. And men in this category are also serious boozers. Oh, and the heavy meat eaters were older, too—so many of them were well into their 70s by the time they suffered the consequences of too many sausage rolls.

And the people who ate the most processed meat—which the study qualifies as more than 160 grams per day (about six sausage links' worth)—didn't only die of cardiovascular diseases and cancer, the things we associate with a bad diet; they also died of lots of "other causes," a category that includes car crashes, accidental injuries, and other non-food-related causes. (The study's big chicken eaters, on the other hand, were the Girl Scouts of the data pool: They don't smoke much, they eat lots of vegetables, exercise, go to college, and no doubt brush their teeth, wear seatbelts, and get regular checkups.)

The researchers did try to adjust for the booze and smoking, education, and even sugar consumption, but they couldn't completely factor those things out or there would be very few people left in the study. Out of 127,000 or so male participants, a mere 619 were heavy processed-meat eaters who'd never smoked. And as it turns out, the scientists couldn't find a significant association between heavy processed-meat consumers and nonsmokers, only former or current smokers—a finding they acknowledge is "compatible with residual confounding by smoking." Which begs the question: Is it the bacon or is the cigarettes that's killing these people? Concluding that it's only the bacon that's the culprit here seems like a stretch.

What's more, not even 1 percent of of the people who died during the 12 years of the study were among those who ate the most processed meat. Zoe Harcombe, a British obesity researcher (and a participant in the EPIC study), points out that the researchers had to group the participants in an unusual way, so that the number of people in the high-processed-meat consumption category was very small. (There were so few women in this category that the association with processed meats and mortality wasn't statistically significant for them.) She writes, "This is like doing a survey about alcoholism and mortality and making the top group so small that it includes Billie Holiday and George Best and making headlines on this basis."

Of course there are plenty of good health reasons to avoid processed meats—think pink slime or listeria—not to mention environmental ones like factory farming and climate change. The EU researchers also point to salt, extra fat, and carcinogens like nitrite that are found in processed food as potential culprits that should make any health nut wary. But not all processed meat is created equal, either. The difference between some nice Italian prosciutto and that Spam-like stuff in Lunchables is vast (and perhaps one reason why Italians have a longer life expectancy than Americans).

In the final equation, eating some bacon for breakfast now and then probably isn't going to kill you, and eating a nice (grass-fed) steak once in a while might even extend your life.

I can haz cheezburger ?

I only eat tossed salads anyway.

I thought the point of the EU study was that the preservative elements of processed meat, particularly sodium nitrate, were the real killers rather than the meat itself.

I cut down the carbs, went up on the protein, and my health hasn't been better. A lot of shit that's put out there is false, like the low-fat craze. That was total bullshit. You have people doing low-cal, and they're still enormous. Atkins was right -- even though he wasn't the one who came up with the whole high protein idea. People get off of insulin, blood pressure medication, and other pills when they start doing low-carb. People are so stubborn to accept reality. They still stick to that ludicrous food pyramid.

Would you like some iced tea with that salad?

r4 - What do you do to combat the Satanic breath that an Atkins-type diet creates? I would rather kiss my dog after she's eaten cat poop than be stuck in an elevator with someone with high protein breath.

r6, my breath is fine. Thanks for your concern.

Now wouldn't you have vegetables with your meats, R6? Aren't the carbs we eliminate complex carbs like breads and pastas? So unless people don't brush their teeth, or just literally eat meat all the time, their mouths should be fine?

I stopped eating breads and pastas, so I eat steamed vegetables and a mix of white and red meat, brush my teeth twice a day and floss, and I smell ok.

R4, Atkins stresses going down on carbs and up on fat. Some increased protein comes along for the ride. You've been reading biased media reports. And adding more green and yellow veggies is OK as well. Just lay off the pasta, sweets, bread, etc.

r8 - No, eating a few vegetables doesn't help. Rancid, rancid breath that toothpaste does not touch. After a week of it, I couldn't stand it. Perhaps it improves over time though.

R5, I think you missed the joke.
