There are few aspects of daily existence, particularly in modern society, that are more pervasive than advice on what we should eat. Everyone, including friends, family, strangers on Twitter and self-proclaimed experts in nutrition and health, seems to have an opinion on how to eat in order to improve and prolong our lives. Even legitimate organizations dedicated to the health and well-being of the population add to the cacophony of recommendations on diet.
Readers of Science-Based Medicine should be well aware of the current popularity of avoiding gluten, even absent the diagnosis of celiac disease or thoughtful evaluation for another related condition. Gluten, we are told by gurus and authors of books like Wheat Belly and Grain Brain, is the one true cause of a host of medical complaints, even autism. Avoid gluten at all costs, they say, and watch the pounds melt away or experience the clearing of your “brain fog.” (more…)
Happy New Year! Today’s post was some old material, dusted off, repackaged, and updated for 2015.
New Year, New You, right? We’re just into 2015, and you’ve resolved to finally get serious about your health. Starting today. But first need to cleanse yourself, eliminating last year’s lifestyle and dietary sins. You’ve seen the ads and the Facebook links, all suggesting you need a “detox”, “cleanse” or “flush” to be healthy. Supplements, tea, homeopathy, coffee enemas, ear candles, and footbaths promise you a detoxified body. Amazon has entire detox and cleansing categories in supplements and books. The descriptions all suggest detoxing will deliver a renewed body and better health — it’s only seven days and $49.95 away. Dr. Oz has several detox plans — you just need to decide which one. The local naturopath sells detoxification protocols, including vitamin drips and chelation. Even your pharmacy probably has a wall of products for sale. Wouldn’t a purification from your sins of 2014 be a good idea to start the year? Unfortunately, there’s something very important that detox promoters aren’t telling you. (more…)
Even though yesterday was Easter, and, as unreligious as I am, I was still thinking of taking it easy, there was one target that popped up that I just couldn’t resist. My wife and I were sitting around yesterday reading the Sunday papers and perusing the Internet (as is frequently our wont on Sunday mornings), when I heard a contemptuous harrumph coming from her direction. She then pointed me to an article in our local newspaper entitled Gluten-free beauty products in demand among some customers. Now, I must admit that I haven’t been keeping up with the gluten-free trend, other than how easily it fits within the niche of “autism biomed” quackery, where, apparently, nearly every “biomed” protocol for autistic children demands that gluten be stripped completely from their diets, lest the evil molecule continue to infect them with the dreaded autism. I’ve kept an eye the literature, but haven’t really written about gluten. That’s why I could immediately tell why my wife had called my attention to the article:
Amy Soergel’s lip gloss was making her sick. The problem, she realized, was gluten — hydrologized wheat protein, to be exact. Then she went to the hairdresser who used a shampoo that made her neck burn. Again, it contained gluten.
“There’s hidden gluten in many places you may not consider,” including stamp and envelope glues, toothpaste and lip balms, said Soergel, who has a store, Naturally Soergel’s, near Pittsburgh that caters to people with allergies. Indeed, for people with celiac disease, a bit of gluten that might get swallowed from a lipstick or a stream of shampoo in the shower can be enough to cause illness.
A slew of gluten-free skin care products have come on the market, including items from well-known companies such as Murad, Dr. Hauschka, EO, MyChelle, Suntegrity, Acure and derma-e. Many are sold in Whole Foods and other health food stores. If they’ve been certified by a third-party agency, an icon usually appears on the packaging.
Whole Foods. Of course, it had to be Whole Foods (among others). Let’s take a look at the whole gluten-free movement and then at the end I’ll revisit the question of gluten-free cosmetics and skin products.
Much of the therapeutics I was taught as part of my pharmacy degree is now of historical interest only. New evidence emerges, and clinical practice change. New treatments replace old ones – sometimes because they’re demonstrably better, and sometimes because marketing trumps evidence. The same changes occurs in the over-the-counter section of the pharmacy, but it’s here marketing seems to completely dominate. There continues to be no lack of interest in vitamin supplements, despite a growing body of evidence that suggests either no benefit, or possible harm, with many products. Yet it’s the perception that these products are beneficial seem to be seem to continue to drive sales. Nowhere is this more apparent than in areas where it’s felt medical needs are not being met. I covered one aspect a few weeks ago in a post on IgG food intolerance blood tests which are clinically useless but sold widely. The diagnosis of celiac disease came up in the comments, which merits a more thorough discussion: particularly, the growing fears over gluten consumption. It reminds me of another dietary fad that seems to have peaked and faded: the fear of Candida.
It wasn’t until I left pharmacy school and started speaking with real patients that I learned we are all filled with Candida – yeast. Most chronic diseases could be traced back to candida, I was told. And it wasn’t just the customers who believed it. One particular pharmacy sold several different kits that purported to eliminate yeast in the body. But these didn’t contain antifungal drugs – most were combinations of laxative and purgatives, combined with psyllium and bentonite clay, all promising to sponge up toxins and candida and restore you to an Enhanced State of Wellness™. There was a strict diet to be followed, too: No sugar, no bread – anything it was thought the yeast would consume. While you can still find these kits for sale, the enthusiasm for them seems to have waned. Whether consumers have caught on that these kits are useless, or have abandoned them because they don’t actually treat any underlying medical issues, isn’t clear.
The trend (which admittedly is hard to quantify) seems to have shifted, now that there’s a new dietary orthodoxy to question. Yeast is out. The real enemy is gluten: consume it at your own risk. There’s a growing demand for gluten labeling, and food producers are bringing out an expanding array of gluten-free (GF) foods. This is fantastic news for those with celiac disease, an immune reaction to gluten, where total gluten avoidance is essential. Only in the past decade or so has the true prevalence of celiac disease has become clear: about 1 in 100 have the disease. With the more frequent diagnosis of celiac disease, the awareness of gluten, and the harm it can cause to some, has soared. But going gluten free isn’t just for those with celiac disease. Tennis star Novak Djokovic doesn’t have celiac disease, but went on a GF diet. Headlines like “Djokovic switched to gluten-free diet, now he’s unstoppable on court” followed. Among children, there’s the pervasive but unfounded linkage of gluten consumption with autism, popularized by Jenny McCarthy and others. Even in the absence of any undesirable symptoms, gluten is being perceived as something to be avoided. (more…)
