Food Babe – Stop Giving Cancer Advice. It Makes You Seem Reckless.


Disclaimer: I’m no expert on cancer. Still, when I put my name to assertions, they’re based in solid science. I have a high-level understanding of how cancers work, which is leagues more than Food Babe can claim. Furthermore, arguing for consensus requires far less expertise than spouting idiocy does. Extraordinary claims require extraordinary evidence.

If you’re a regular reader of mine, you’ve undoubtedly noticed that I frequently pick on Food Babe. As I’ve said before, my primary motivation in criticizing Food Babe, Dr. Oz, Mercola, Vandana Shiva, and other quacks is that they represent everything disgraceful about unscientific fear mongering.


Case in point:  This is an old post that a friend brought to my attention. This friend has a BRCA mutation, so it hits close to home for her.

I was stunned. Talking about an entire scientific field of study that you clearly know zilch about is astounding. I responded as follows on my Facebook fan page:

“This is why ignorance from people like Food Babe makes me so angry. Spouting so called “puzzlement” and “concern” about cancer while you obviously have no idea what you’re talking about is deplorable. First of all, one doesn’t test “positive for the BRCA gene.” *Everyone* has BRCA1 and BRCA2 genes. Both of these genes code for tumor suppressor proteins. When there is a defective mutant allele in certain region of these genes, the tumor suppressor proteins aren’t produced, or don’t function correctly. Still, everyone has a copy of these genes inherited from each parent, so the un-mutated copy produces the proper proteins, thus compensating for the deleterious mutation on the other copy. The problem is it’s much more likely, almost certain that a mutation will occur in one cell on the “good” version, so now both copies are messed up eventually leading to cancer. For someone without one of these inherited mutations, a somatic mutation would have to occur on *both* copies of the gene in the same cell. Statistically, it’s very unlikely that this will happen, so this specific, nasty form of breast cancer will not occur in a person without a mutation inherited from mom or dad. So statistically, a person that has inherited one of these problem alleles is pretty much screwed. (This is a very simplified explanation.) Sorry Food Babe, all the organic kale and healthy smoothies in the world don’t change that. Shame on you. Stick with what you know. And no, you don’t “know” anything about agriculture, chemistry, or biology worth the sugar in my toxic morning coffee.”

To put it simply, there are two main types of genes associated with cancer: Proto-oncogenes and tumor suppressor genes. Proto-oncogenes code for proteins that regulate cell growth. When these proteins are synthesized properly, some tell cells when they should grow (e.g. during fetal development.) Other proto-oncogenes help synthesize proteins that tell cells when to take one for the team and die. Certain mutations in these genes can lead to cells growing out of control, AKA cancer.

BRCA genes are tumor suppressor genes. The relevant deleterious mutations in BRCA1 and BRCA2 demonstrate the “two-hit” tumor suppressor carcinogenesis model, also known as the Knudson Hypothesis. We each get two copies of all twenty-two somatic chromosomes, one from each parent, plus one sex chromosome from each parent, an X from mom, and an X or Y from dad. We inherit two copies of every gene, including BRCA1 and BRCA2. These genes produce proteins that help repair a specific type of DNA damage. The likelihood of both copies sustaining deleterious mutations in the same cell (two somatic hits) is relatively low.

Let’s say one of the copies you got from either parent is mutated in a way that makes this protein either not work, or not get synthesized at all. (A mutation you get from a parent is called a “germline” mutation; germ cells make sperm and egg cells. Mutations that happen in your body after you’re conceived are called “somatic.”) In this case, you’re born with one hit in every single cell already. All it takes is for the second copy to get mutated anywhere (along with other complex events I won’t describe today,) and you’re well on your way to cancer. Thus, when someone is born with one of these BRCA mutations, s/he is far more likely to develop breast or ovarian cancer – up to a 65% or more lifetime chance or breast cancer. In addition, a parent with an inherited mutation has a 50% chance of passing it to each offspring.

Imagine a situation in which most people get to roll two dice, and rolling two 3s means a likely cancer sentence. People born with these mutations have two dice, but one of them has 3s on all sides.

You see Food Babe, there is much that scientists have to learn about cancer. But there is much that science already knows. While my explanation is extremely abridged, it is embarrassingly obvious that you DON’T UNDERSTAND WHAT YOU’RE TALKING ABOUT. It’s painfully clear that you are “puzzled.” Not for the snarky reason you imply, but because you have no idea how these type of cancers happen. If you did, you would realize that eating the “best foods” or avoiding toxins won’t “prevent cancer naturally.”

Yes, cancers are immeasurably more complex than I’ve described them here. Yes, healthy diet and lifestyle are important. But what you deem “healthy” and what experts deem healthy are vastly different. Environmental factors that cause cancer include smoking, obesity, certain viral infections, and radon gas. Factors that don’t cause cancer include GMO foods, vaccines, sugar, and caramel coloring in lattes. Things that don’t prevent or treat cancer include organic foods, herbal remedies, or green juice. What you’re doing boils down to victim-blaming and fear-mongering.

In case you haven’t noticed, the pro-science community has had enough. Extraordinary claims require extraordinary evidence. Put up or shut up.

  1. HI Kavin – new subscriber here, and I am very glad to have found your website. As a dentist, I often deal with quack beliefs (although not nearly as many as physicians have to do), but I’ve recently been confronted more frequently with patients referencing Food Babe, “Drs” Mercola and Oz, etc., and so my frustration level has been rising. Therefore, I’ve been looking for more resources to reference when trying to reason (however unsuccessfully or fruitlessly it often seems) with people who mistakenly follow those people. So for the moment, I’d just like to say “Thank You” for putting all the time and effort into these articles, and you’ll probably see me around commenting and sharing your articles. 🙂

    1. Hi Charles. Thanks for following! I’m glad to be a resource for you with your patients. “Drs” Mercola and Oz are also on my list of frustrations. Have you read Science Based Medicine and Genetic Literacy Project? Both are good resources (and I contribute at Genetic Lit Project.)

      1. Kavin, I had seen Science Based Medicine but not spent much time on it yet, but I’ve definitely spent some time on the Genetic Literacy Project site. Excellent resources, indeed.

        I’m in the midst of several projects for my office, and it’s also our busiest time of year, so I”m a bit swamped currently, but I hope to start writing a series of articles on my personal blog ( and on my dental office website ( in 2015. One of the biggest challenges I personally face, however, is trying to write about these topics in a way that most of my patients and readers can understand. Perhaps you can offer some suggestions on how to “translate” these issues into language that the general public can grasp? In addition, since women are so involved in making all medical/dental decisions and appointments, I have to write for women, but you know, well….I’m a guy and that’s kinda hard! LOL

        So basically, any resources or suggestions/tips on how to write on these topics in the most approachable manner, without coming across as condescending, would be much appreciated. Thanks!

  2. Food Bimbo is also frequently “shocked.” Hopefully, posting facts will influence her, but not likely., She has no clue whatsoever what those are. They would confuse and slow her down too much. She and her “co-conspirators” are seriously deluding their lemmings. One, of them, Dr. Josh Axe is now saying that “pulled coconut oil” cures cavities and prevents just about everything else. He’s a chiropractor claiming skills of a physician. I’m an extensively trained, experience electronics repair technician, including microwave radio transmission. I should, thus be as qualified as the is to spew blather about food, vaccines, chemicals and other subjects unrelated to my experience. I’ll try to be even more wrong about the subject than Food Bimbo. I doubt that’s possible, though.
