Cancer diet

Anybody else see this article about a journalist who gets cancer and starts praising nutribabble? The description really says it all: After beating cancer, Scott DeSimon rediscovered his appetite—and lost his skepticism for wellness and nutrition trends. Meet the superfoods that guided him back to health.”

The gist is that the author gets cancer, goes through conventional treatment, loses a bunch of weight, finishes the treatment and attempts to regain the weight. Eschewing what he sees as healthy eating (“I know what constitutes a healthy diet: lots of vegetables, meat mainly as a flavoring, no processed foods”) he goes for quantity over quality and calories over micronutrients in an effort to regain the weight he lost during radiation. Unsurprisingly, he makes himself sick by ingesting copious quantities of fast food and restaurant food. So, he turns to a professional. Sadly, not a dietitian nor any sort of cancer specialist. Instead, he goes to Dr Lipman who has devotees such as Gwyneth Paltrow, as if that’s a selling point. Dr Lipman is a big fan of superfoods, cleanses, supplements, and has a website with testimonials. All of which are red flags of quackery and basically amount to a red sail, or whatever you want to picture for an oversized red flag. There are testimonials from actors and fellow quacks like Mark Hyman and Christiane Northrup.

Once the author goes on the extremely restrictive diet prescribed by Lipman, he magically feels much better and he slowly starts to regain weight. While he claims to be skeptical about the regimen, it comes across as hollow to me. It’s like I rolled my eyes but threw away all of my food as started living off cashew milk and chia seeds. Of course he’s going to feel better, he’s finished radiation treatment, regained his tastebuds, and started eating again (1). I’m not saying that the diet Lipman put him on is bad, I’m just saying that there are some pretty significant confounders here and correlation does not imply causation. It’s quite likely that he would have started to feel better on a much more relaxed diet and that the strict diet is falsely being credited with his recovery.

I don’t think that anyone with cancer should feel like they have to give-up gluten or sugar or coffee. They also shouldn’t feel as if they have to subsist off expensive “superfoods” and supplements. Healthy eating, whether you have cancer or not, does not have to be a complicated or costly endeavour.

Can you cure cancer by cutting sugar?

After a conversation with a reader about ludicrous nutrition advice he was given after receiving a cancer diagnosis I felt the need to address the issue. I can’t tell you how many times I’ve been told by people that cancer cells feed on sugar so people with cancer shouldn’t eat sugar. There are so many things wrong with this.

Sure, cancer cells use sugar in the same way that ALL cells in your body do. Sugar, in the form of glucose, is the energy source for all of your cells. If you have cancer and eat sugar you are not “feeding” the cancer. Conversely, if you stop eating sugar, you’re not going to be able to starve your cancer to death. You get glucose from more sources than table sugar and sugary snacks and if you’re not consuming enough glucose to fuel your body it will start making it for you.

I’m sure that most people who believe that consuming sugar helps cancer grow are simply well-meaning misguided individuals. Unfortunately, there’s a whole industry built on preying on people’s desperation. When someone is diagnosed with cancer, in many cases they’ll turn to whatever cure or treatment they can. As food is “natural” it’s not surprising that people would want to look for dietary treatments. That’s where the predatory wellness warriors come in telling people to cut all sugar from their diets amongst other nutritional “cures’ with absolutely no scientific basis.

A google search for “food cure for cancer” yielded the following results:

Vegetables Juices. The RAW vegetables you should focus on are carrots, cabbage, green asparagus, broccoli, red beets (i.e. beetroot), beet tops, cauliflower and related vegetables. Peppers also have cancer-fighting substances. The spice turmeric can be added as well.

Brussels sprouts, bok choy, Chinese cabbage, broccoli, and cauliflower all contain sulforaphane and indole-3-carbinols (I3Cs), two potent anticancer molecules. These molecules help the body detoxify certain carcinogenic substances and can help prevent precancerous cells from developing into malignant tumors.

It’s all bullshit. If cancer could be miraculously cured by eating “superfoods” or “raw food” or having intravenous mega-doses of vitamins no one would be dying of cancer anymore. Scientists would have stopped researching cancer cures years ago.

Nutrition and your overall diet certainly play a role in cancer risk but it’s not the only risk factor. If you have cancer, I recommend working with a dietitian who specializes in nutrition for cancer patients to optimize your nutrition while you undergo appropriate treatment overseen by an oncologist.
