Given the concern over bacterial resistance to medically-important antibiotics, it is vital that we find alternatives. Yet they also must have a biologically sound mode of action and be proven to be effective. It is difficult to conceive how a solution so dilute that not one molecule of active ingredient remains, where the premise of the mode of action depends on water having a “memory” of the ingredient (as opposed to all the other contaminants within that water), can possibly have any verifiable impact on disease. Indeed, there are no studies to date that show positive, replicable effects of homeopathy compared to conventional treatment.
Personally, I have no issue with any alternative therapy has been shown to be an effective alternative to conventional drugs (note that homeopathy does not fall into this category). When I underwent chemotherapy for breast cancer, I had some reiki sessions. Did I believe that energy was being channeled by the reiki healer and making me better? Honestly, no. Would I have ever considered giving up the chemotherapy? Absolutely not. But the focused breathing and relaxation certainly helped with pre-chemo anxiety. Would taking Rescue Remedy or a similar homeopathic preparation have helped? If I’d believed that it would – yes, probably. But that is biased by the placebo effect – it’s not the same as the treatment being independently effective. One of the claims made for using homeopathic treatments in animals is that they are independent of the placebo effect – they don’t have the expectation that the tincture administered is going to cure their lameness or mastitis. Yet when we assess the results, it’s not the animal who’s reporting the success or failure of the homeopathic treatment, it’s the farmer.
So let’s examine a scenario. A farmer has two mildly sick cows (e.g. slightly lame, or unwilling to eat with a raised temperature) within the herd. Both are moved to the hospital pen, given fresh bedding, water and feed plus a homeopathic remedy. Cow A gets better – hoorah for homeopathy! Cow B doesn’t and has to be treated with antibiotics – boo! Does this mean homeopathy works in 50% of cases? No. There’s no control treatment here, no evidence that Cow A wouldn’t have got better without homeopathy – some diseases just need time, TLC and the cow’s own immune system for recovery. Did the farmer cut antibiotic use? Yes – Cow A didn’t receive it. Yet again there is no evidence that this is due to the homeopathic treatment. How many times have we as humans debated whether to go to the doctor because of a minor ailment, then have found that it’s cleared up without medical treatment? It’s not miraculous, it’s simply our immune systems functioning as they are intended to.
In the absence of controlled experiments that compare homeopathic treatments to both conventional antibiotics and no veterinary treatment (save for good animal husbandry), it is disingenuous to claim that homeopathy is successful in treating bacterial disease or can effectively be used to replace antibiotics. We need to look to veterinarians and scientists when making decisions about animal care and treatment rather than relying on anecdotal data from those with royal connections. After all, HRH Prince Charles may have reduced antibiotic use on his farm, but I can also claim to have reduced antibiotic use in my household through dairy consumption – my toddler has a serious cheese addiction and has never had to take antibiotics. Hoorah – cheese is the new homeopathy!!*
(*obviously I am being sarcastic here for those who missed it, though the extent of cheese consumption and fact that she’s never had antibiotics are both entirely true)
My Twitter feed is being taken over by two things: 1) arguments and 2) comments that are going to cause arguments. Almost every tweet appears to draw a contrary comment – I’m tempted to post “Elephants have four legs and one trunk” just to see how many people reply “No, there’s an elephant in South Africa called Minnie who only has three legs but has two trunks…”
The latest discussions (debates? arguments? long drawn-out 140-character battles?) have related to the safety of GMOs. Without exception, the argument from the nay-sayers comes down to “We don’t know what the long-term effects are, so we should ban them until we can conclude that they’re safe.”
In other words, we’re trying to prove a negative – show me that there’s no adverse effects whatsoever and I’ll believe it’s ok. Utterly impossible. Can you be absolutely sure that the screen you’re reading this on isn’t causing constant, minute but irreparable damage to your eyes? Water, that essential nutrient without which humans, animals and plants would die, can kill through drowning or intoxication. Even oxygen, without which brain cells are irretrievably damaged in just 10 minutes, causes seizures and death when inhaled at high pressures. Should we ban these, just in case?
Perhaps we should take a long-term approach to all new technologies. iPhones were only introduced seven years ago, yet many of us spend considerable amounts of time typing on them, or holding them to our ears when they’re not in our pockets – what health-damaging consequences could these shiny new toys confer? What about the now-ubiquitous hand sanitizer? Once only the province of hospitals and germophobes, it’s now sloshed around by the gallon. Touted to kill 99.9% of harmful bacteria – what harm could those chemicals be doing to our fragile physiology?
I’ve yet to meet anybody who, when scheduled for quadruple bypass surgery, demanded that the surgeon only used techniques developed in 1964; or a type I diabetes sufferer who would only use insulin produced from pigs, as it was originally in 1923. When I was treated for breast cancer, I jumped at the chance to be part of a clinical trial involving a new monoclonal antibody treatment, regardless of the very slight risk of heart damage. In medicine, we seem happy to trust that science has the answers – not surprisingly, we prefer to survive today and take our changes with side-effects tomorrow.
With regards to food however, the opposite appears to be the case. The first commercial GMO (the Flavr Savr tomato) was introduced in 1994, GM corn and soy were commercialized in 1996, and not one death or disease has been attributed to any of these crops. Yet the “what are the long-term effects?” concern still persists. So how long-term is long enough? 10 years? 20? 50? Should we keep researching and testing these crops for another 80+ years before allowing them onto the market around the year 2100?
If your answer is yes, just pause for a moment and ask your parents, grandparents or even great-grandparents what life was like during the Great Depression in the USA, or World War II in Europe. Consider what life was like when food was scarce or rationed, when, for example, a British adult was only allowed to buy 4 oz of bacon, 8 oz ground beef, 2 oz each of butter and cheese, 1 fresh egg and 3 pints of milk per week. Those quantities of meat and cheese would only be enough to make two modern bacon cheeseburgers.
By 2050, the global population is predicted to be over 9 billion people. I don’t relish the idea of explaining to my grandchildren that they live with food scarcity, civil unrest (food shortages are one of the major causes of conflict) and malnutrition because public paranoia regarding GMOs meant that a major tool for helping us to improve food production was removed from use. In the developed world we have the luxury of choosing between conventional, natural, local, organic and many other production systems. However, we’re in danger of forgetting that not everybody has the same economic, physical or political freedom to choose. If you gave a basket of food to a family in sub-Saharan Africa subsisting on the equivalent of $30 per week, would they refuse it on the basis that the quinoa wasn’t from Whole Foods, the meat wasn’t organic and the tofu wasn’t labeled GMO-free?
When we have sufficient food being supplied to everybody in the world to allow them to be healthy and productive, we can then start refining the food system. Until then, the emphasis should be on finding solutions to world hunger, not forcing food system paranoia onto those who don’t have a choice.
