Due to some scheduling freedom, I’ve lately become a bit nocturnal, and I’ve found myself watching a lot of late-night/early-morning TV. This has given me the opportunity to reflect on the ridiculous ads that companies save until we are maximally sleep-deprived and hopefully stupid enough to believe the crap that they are shoveling. Frankly, it is unbelievable.

I wanted to write something all about Dr. Frank’s No Pain Spray, because I’ve seen about nine zillion commercials for that. But once you get over the fact that it’s an oral spray that looks like a breath freshener but that’s supposed to provide all the way up to post-surgery level pain relief (no, I’ll take the Percocet, please), the fact that it claims not one but ten different homeopathic ingredients (slightly increasing the probability that a single non-water molecule might exist in the spray), and the fact that it’s only advertised at 3 AM (not a good sign for credibility), there’s really not a lot more to mock. Borrr-ing. Besides, someone else has done it more thoroughly than I would care to.

However, I think it’s important to say something about a more general problem I have with this class of advertisements. All these diet pills, “male enhancement” tablets, and so on make their claims of widespread success, then display the tiny text: “This product has not been evaluated by the FDA.” Is that enough to meet our legal standard for truth in advertising?

The Federal Trade Commission has this very clear FAQ about false advertising on their website. In particular I think it’s worth highlighting this one.

What makes an advertisement deceptive?
According to the FTC’s Deception Policy Statement, an ad is deceptive if it contains a statement - or omits information - that:

— Is likely to mislead consumers acting reasonably under the circumstances; and
— Is “material” - that is, important to a consumer’s decision to buy or use the product.

It goes on to explain the process the FTC uses to investigate claims of false advertising, and uses the particular example of a mouthwash that claims to prevent colds. The FTC looks from the point of view of a “reasonable consumer” and evaluates both “express and implied claims,” checking to see if the advertiser has enough proof to back them up. In the particular example of medical or other scientific claims, the advertiser is expected to have “competent and reliable scientific evidence.”

I also found a page on the FTC’s website called Dietary Supplements: An Advertising Guide for Industry. It has a lot of important and relevant information, and in particular in section II.C.3 mentions the Dietary Supplement Health and Education Act (DSHEA) disclaimer, “that the statement has not been evaluated by FDA and that the product is not intended to ‘diagnose, treat, cure or prevent any disease.’” DSHEA doesn’t explicitly apply to advertisements, but this document does say that it’s a good idea to include the disclaimer “to prevent consumers from being misled about the nature of the product and the extent to which its efficacy and safety have been reviewed by regulatory authorities.” I was glad to see this example used to illustrate the issue:

Example 34: An advertisement for an herbal supplement includes strong, unqualified claims that the product will effectively treat or prevent diabetes, heart disease, and various circulatory ailments. The advertiser does not have adequate substantiation for this claim, but includes the DSHEA disclaimer prominently in the ad. In face of the strong contradictory message in the ad, the inclusion of the DSHEA disclaimer is not likely to negate the explicit disease claims made in the ad, and will not cure the fact that the claims are not substantiated.

This is a good standard to have. There are two prongs to the DSHEA disclaimer; I’ve usually only seen the first half used (in small and hard-to-read print, no less). The second half, that the product is not intended to provide any actual medical service, would seem ridiculous when compared to the explicit claims of medical service made over and over again in the ad. Of course it’s intended to diagnose, treat, prevent, or cure something! The first half of the disclaimer, though, is even less effective at offsetting the false advertising. The lies may not have been evaluated by a regulatory agency, but that doesn’t make it okay to lie. It’s the advertiser’s job to make sure what’s in the ads is true, and this feeble attempt to displace blame is laughable.

The problem, then, is not that we don’t have a good standard delineating what’s false advertising, bur rather that the standard is not being enforced. These advertisements aren’t just stupid, they’re nefarious — they’re lies told only when viewers are expected to be at their weakest emotionally and blurriest rationally.The FTC needs to step it up and get these cranks off the air.

The New York Times recently ran a story about how best to prepare vegetables. It turns out that raw foods and vegetables aren’t necessarily better for you than they would be if you cooked them — and sometimes they’re worse. Tara Parker-Pope writes:

The amount and type of nutrients that eventually end up in the vegetables are affected by a number of factors before they reach the plate, including where and how they were grown, processed and stored before being bought. Then, it’s up to you. No single cooking or preparation method is best. Water-soluble nutrients like vitamins C and B and a group of nutrients called polyphenolics are often lost in processing. …

Fat-soluble compounds like vitamins A, D, E and K and the antioxidant compounds called carotenoids are less likely to leach out in water. Cooking also breaks down the thick cell walls of plants, releasing the contents for the body to use. That is why processed tomato products have higher lycopene content than fresh tomatoes.

In January, a report in The Journal of Agriculture and Food Chemistry concluded that over all, boiling was better for carrots, zucchini and broccoli than steaming, frying or serving them raw. Frying was by far the worst.

Surely it’s a good idea to make an effort to include some raw vegetables in our daily consumption. It’s interesting to note, though, that the conventional wisdom that raw is better is not true in all cases. Some people, however, take that supposed wisdom to an unhealthy extreme. The “raw food diet”, typically also vegan, is about the strictest interpretation of all-natural eating. As this About.com summary explains, followers of this diet avoid eating anything heated to over 116° F (47° C).

On face it seems a little silly to me that in the search for the most supposedly natural lifestyle, some people have chosen to go back to before the discovery of fire. But then, even About.com has filed this article in the alternative medicine category, along with articles about acupuncture (equally effective when you’re pretending to do it) and homeopathic remedies (which are based in part upon the premise that diluting something makes it more potent).

Of course, even those of us who don’t follow extreme diets like this one fall prey to this simplistic sort of thinking all the time. Grocery stores can charge higher prices for organic food because so many of us assume that if it’s organic it must be worth the extra cost. And sure, pesticides and other chemicals used on food can be dangerous in large quantities, but worm-filled or mold-covered food isn’t exactly healthy either. (I’m reminded of the Vital Signs podcast from last February that described the case of an infant who contracted botulism from some natural honey.) The healthiest lifestyle is actually a happy medium between limiting the “unnatural” chemicals we consume and avoiding the all-too-natural ways of getting sick.

I believe this highlights a major fallacy in the popular conception of health: that things are better for you if they’re more natural. First of all, “natural” isn’t even an adjective that can be clearly defined, given that we can’t exactly return to some sort of Hobbesian state of nature to look around and take notes. But also, many things commonly viewed as “unnatural” such as technological and chemical advances have actually vastly improved our lives. I’m happy to live in a world with telephones, penicillin, electricity, printing presses, the wheel… and I’m also glad we have pasteurized and vitamin-fortified milk, irradiated meat, and rice genetically modified to have 20 times the beta carotene.

At the end of the day, I think we just have to remember that the story is always more complicated than it seems at first. It’s appealing to think there are clear cut rules for how to live the healthiest life, but following a rule like “natural equals good for you” can actually be detrimental to your health. A little bit of critical thinking can go a long way.
