Homeopathy is one of the most enduring forms of snake oil available to consumers; it has been duping people since 1814. But the United States government only recently decided to clamp down on these bogus treatments, with a new policy from the Federal Trade Commission.
The FTC’s policy statement explains that the agency will now ask that the makers of homeopathic drugs present reliable scientific evidence for their health claims if they want to sell them to consumers on the US market.
Mustering that evidence is likely to be difficult given that homeopathy is a pseudoscience.
The main idea behind homeopathy is that an animal or plant extract that causes symptoms similar to the ones a person is suffering from can cure the symptoms. An example: Because onions make eyes tear and noses run, diluted onion extract is thought to cure cold and hay fever. So homeopathic remedies on the market are just extremely diluted versions of plant or animal extracts believed to bring relief to symptoms.
The trouble is that whenever researchers have looked at the homeopathic treatments, they find they do not actually contain traceable amounts of the original plant or animal material they were supposedly diluting.
The galvanic skin response
I was recently asked to look into a product called Zyto technology. This is an electronic device that you place your palm on top of so that it can read your “galvanic skin response” (GSR) to specific stimuli. It then uses your responses to prescribe a specific treatment.
It seems nearly all your friends are doing special cleansing diets. Should you do one too?
Transcript via inFact:
Cleansing diets are a food fad that’s been around for decades, from the Hollywood 48-Hour Miracle Diet, to lemon & maple syrup concoctions, to today’s absurdly overpriced high-sugar fruit smoothie drinks that you buy an in impressively multi-colored, day-specific pack.
Notice that accredited healthcare providers like medical doctors and dietitians never recommend that you buy these cleansing products — they recommend the most basic (and free) health advice of all: eat right and get some exercise. It’s only the unaccredited, unlicensed tradespeople like nutritionists and yoga teachers who will advise you to buy cleansing products — and not surprisingly, will often sell them to you themselves.
Why don’t doctors advise cleansing for general health? Because there is no such thing in medical or dietetic science. The idea that toxic substances from a normal diet build up in your body and cause health problems is a fantasy invented by marketers. Proof: Humans and animals all exist fine, and have for millions of years, without these products. We have perfectly functioning systems already built in: kidneys and livers. The technical medical terms for detoxification are “poop” and “pee”.
The Huffington Post recently published an article by Dr. Neal Barnard, MD. It is titled “New Study explodes the Eskimo Myth” and it makes some very salient points about the development of the supplement fish oil, its historical roots, and subsequent evaluations of its benefits. This was a pleasure to read—a rare science-based examination by the Huffington Post. Dr. Barnard points out that the original conclusions from investigating fish oil appear to be tainted by researcher error. The seminal 1976 survey had demonstrated abnormally low rates of heart disease among Inuit despite a high fat diet. But further research has shown that the original study was in fact poorly done and did not properly evaluate the true health history of the Inuit. A recent study in the Canadian Journal of Cardiology reviewed the original 1976 research and outlined its major flaws. In 2003 and 2009 follow-up studies demonstrated higher levels of cardiovascular disease among the Inuit peoples, essentially invalidating the hypotheses. If Inuit diets are not cardio-protective what does that say about diets high in Omega-3 fatty acids overall? What does this mean to fish oil supplementation?
Fish oil was developed out of the so-called “Eskimo Anomaly”: the observation that Inuit consumed a relatively high-fat diet rich in blubber and fatty fish, yet also appeared to have low rates of heart disease. As with the “French Paradox,” scientists proposed a possible cardiovascular protective benefit from diets high in Omega-3 fatty acids, a proposition that has formed the basis of fish oil supplementation. The idea that fish oil can help prevent heart disease is has now become entrenched conventional wisdom. But if the original study has been invalidated, we must reconsider whether or not fish oil is actually beneficial. Is the discovery of fish oil a lucky accident or is it just snake oil?
It would seem highly improbable that an incorrect guess about the Inuit’s health would lead to an effective cardiovascular treatment, but it’s not impossible. Science is filled with happy accidents. The fact that fish oil was discovered due to an erroneous evaluation actually says nothing about the effectiveness of the treatment. Fish oil is one of the very few supplements in the United States to have been developed into a prescription drug, called Lovaza. Its active ingredient is Omega-3-acid ethyl esters, which are metabolized by the body into Omega-3 fatty acids. This drug is prescribed to lower serum triglycerides. Randomized, controlled research does show that it seems to be of moderate benefit for hypertriglyceridemia, a condition that predisposes people to cardiovascular disease and prancreatitis.
Unfortunately, proponents of complementary and alternative medicine (CAM) often suggest that fish oil treats a variety of related and unrelated illness. In CAM, the uses for supplements seem to always exceed the evidence; fish oil is no different for them, and has been recommended to treat everything from cancer to headaches. Despite the large amount of research surrounding fish oil, CAM proponents always seem to find areas that haven’t been studied, using what I call the “drug of the gaps argument” and using what we don’t know about supplements to make wild speculation about benefits. In other words, if we haven’t done any studies for fish oil’s effect on stubbed toes, their assumption is that it will probably cure stubbed toes. Fish oil has tons of research, a lot is known about it and it is safe to say that we have a good grasp of what it can and cannot do. I think it is useful to review what is currently known about the supplement, highlighting what it is most commonly purported to treat as well as its problems.
