My Beef with Beef

I can’t tell you how furious I am about what I feel is the meat industry’s blatant disregard for human health. While I’m no vegetarian, I saw this study in the Archives of Internal Medicine, and let’s just say, I’m not buying the “Happy Cows” line.

The researchers looked at 90,000 women. That’s a huge study. They compared US and UK women, and here’s what they found:

Eating more than 1.5 servings of meat daily doubles a young woman’s risk of breast cancer. What concerns me is the type of cancer which had double the risk: hormone receptor-positive breast cancer. To me, that says something pretty sobering about the meat industry’s production habits.

Both the study, and the BBC News article that covered it, are cautious to merely “suggest” a link between eating red meat and increasing – doubling – the risk of breast cancer. It doesn’t take much to read between the lines here.

The reason I think this study is really important to highlight is not because I hope to bandy a statistic like “double the risk!” about. (Remember the Statistics Game: always consider context and relative risk or results.) It’s important because the women who ate high amounts of red meat had double the risk of hormone receptor-positive breast cancer. That is a big issue, namely, because the American meat industry uses growth hormone like it’s manna from Heaven. Growth hormone helps the animals get bigger, faster, which translates more profit – but I’m pretty skeptical about how this practice could possibly be in the interest of public health. I just wonder how these people sleep at night knowing their profits come at the expense of other human beings.

Personally, I believe it’s clear that human physiology supports being omnivorous. No culture anywhere at any time has done without some sort of animal flesh, whether it’s fish, beef or reindeer. So I’m not “anti-meat”. However, I am strongly opposed to the way meat is produced in this country: quickly, unethically, with little regard for the animals or the people eating the animals. That’s why I only buy meat that is free-range, local, organic and definitely hormone-free.

The researchers were careful not to draw any ultimate conclusions. I think we can probably begin to draw our own, with some additional critical considerations:

1) Processed meats generally contain a chemical known as heterocyclic acid, which has been shown to cause cancer;

2) Red meat, of course, contains iron, which can sometimes encourage the growth of some types of tumors (though this isn’t a significant concern, likely);

3) The standard line: “The biggest risk factors for breast cancer remain gender and increasing age.” This from specialist Maria Leadbeater, quoted in the BBC article. Fair enough.

You want comments? We got comments:

Imagine you’re George Clooney. Take a moment to admire your grooming and wit. Okay, now imagine someone walks up to you and asks, “What’s your name?” You say, “I’m George Clooney.” Or maybe you say, “I’m the Clooninator!” You don’t say “I’m George of George Clooney Sells Movies Blog” and you certainly don’t say, “I’m Clooney Weight Loss Plan”. So while spam is technically meat, it ain’t anywhere near Primal. Please nickname yourself something your friends would call you.
