A number of readers have sent me links (thanks, readers) to a new study coming out of the UK that raised some eyebrows all across the Internet earlier this week. The headlines seemed to scream from everywhere “Do High Fat Diets Make Us Stupid and Lazy?” That, in turn, made me scream, so I took a look at this paper in the Federation of American Societies for Experimental Biology: Deterioration of physical performance and cognitive function in rats with short-term high-fat feeding
What I found was a less-than-impressive short-term study on rat performance that told me what I already knew: that it takes a while for new gene expression to really kick in when you radically shift diets. Just like some of you are seeing in the 30-day challenge. So what?
I thought I’d forgo my regularly scheduled “Dear Mark” Monday post (or “Dear Readers” as the case may be) for a subject very near and dear to my heart: the constantly-evolving, ever-confusing ways of the food rating labelers. Whether it’s the AHA-approved red “Heart Healthy” stamps that implore overweight diabetics to stuff themselves with “healthy” whole grains or the mention of antioxidant and fiber content somehow making that sugary breakfast cereal good for your kids, packaged food distributors seem to love making outlandish claims that bear little to no fruit. It’s incredibly effective, though, for the same reason people will believe anything they hear on TV or uttered by someone with an official title. We’ve already got a far-reaching bunch of bureaucrats at the FDA deciding which macronutrients to highlight and which to demonize on the official nutritional labels that adorn the back of every packaged food item, so the natural next step is a mishmash of extraneous labeling that tries to make nutritional recommendations based on the FDA data (which is itself based on flawed, misguided, or even blatantly false science).
As you may know, I’m not a huge fan of sunscreen lotion. I just don’t think it’s all that necessary. If you’ve had enough Vitamin D skin production for one day, and you’re worried about burning up, using physical barriers – like shirts, hats, umbrellas – to impede the sunlight is better than slathering your skin with powerful chemicals. Still, in the event that the only thing standing between you and a second-degree sunburn is the application of some lotion, have at it. Just be aware that, according to a recent NY Times piece, there is some seriously misleading marketing lingo circulating in regards to SPF counts.
It’s a headline you’ve probably seen by now splashed all over the news sites and channels – “Eating More Red Meat Ups Mortality Risk.” (Red meat once again wears the black hat: surprise, surprise.) Actually, millions of readers/viewers have likely stumbled across the caption and unfortunately taken it at face value. But you know us by now. It’s just too much fun being the merry skeptics when it comes to these sound bites of misinformation.
Last month we brought you news (and humble perspective) on the pharmaceutical industry’s off-label marketing practices. Just a couple weeks after the fact, what before our wondering eyes should appear? News that a glaucoma drug (Lumigan) was just approved by the FDA for off-label use as an eyelash enhancer. Call us suckers, we know, but we couldn’t resist taking the bite. Finding new uses for existing poor selling drugs has become a cottage industry. Reminds me of the old SNL skit, “Shimmer. It’s a dessert topping AND a floor wax!”
