Hello everyone! Thank you for taking some time out of your busy schedule today and stopping by our blog! Before you begin to read this post, please visit our friends over at theCountyfare.net. They’re a lovely, family-orientated nutrition-based site fully supporting and supplying everyone with evidence-based nutrition advice. They wrote this fantastic article on Gluten-Free (GF) diets last week that prompted us to write a response… only it turns out we actually had a lot to say!
Which is exactly what’s brought you to our blog today; this post shows our views and mutual agreements with thecountyfare concerning gluten-free diets.
Before we continue, we would like to quote thecountyfare regarding this topic “…I want to make very clear that one’s being incorrect on or unaware of the underlying science does not make him a bad person or a dumb person….I hope no one will take this article as a personal criticism – I’m attempting to criticize an idea here.”
Now that we have gotten that out of the way, let’s get chatting!
Firstly, we would like to say what an outstanding post guys! To sum it up in one word… Agreed! For non-coeliac sufferers, the ‘gluten free diet’ is a fad.
You only need to enter the search terms: gluten free diet + weight loss into an internet browser to see how out of control another fad diet has become. Is it unprecedented? …No.
When it comes to nutrition people seem to think that just because we all eat, we can all be experts and everybody has an opinion and sometimes strong convictions. Unfortunately these opinions can be born out of ignorance and misinformation which is often the result of cyclic promotion amongst outspoken individuals, who resort to the online equivalent of playground yelling with their dime a dozen SEO snippets.
The truth of the matter is that there are too many people supplying us with unregulated health advice.
Gluten Free Diets And Weight Loss
Anyone opting for a ‘gluten free diet’ as a weight loss tool will ultimately lose weight by reducing kcals. Here’s what the British Dietetic Association (BDA) says in their article entitled “Top 5 Worst Celebrity Diets To Avoid in 2014” in which Gluten free Diet was number 3 “While important for those with coeliac disease … there is no credible published research showing that a gluten-free diet per se leads to weight loss in those without.”
What a gluten free diet can do is make it easier to lose weight because it can be very restrictive; but this isn’t a good thing:
1. A lot of people will cut out staple carbohydrate sources going down this path, e.g. pasta, breads, cereals etc. but do not find suitable replacements…possibly because they think they need to buy like-for-like (but GF products are pricy, so they don’t)…however, legumes, pulses, potatoes, millet, buckwheat, rice etc. are all naturally GF folks.
2. People typically end up cutting out a lot of processed foods in the process, e.g. all of their usual take-aways, cakes, biscuits and doughnuts etc. become off limits; empty calories that would normally expand anyone’s waistline become a thing of the past. However, there are always exceptions; people might substitute cakes for GF ones or make GF / ‘Paleo desserts’ themselves, some of which are full of coconut flour and sugar (this completely contradicts the Paleo diet in the first place!). We’re adamant that you wouldn’t see any cave men hunting ‘cakes’ or grinding up coconuts into flour and refining sugar in order to bake a cake in their imaginary ovens!
3. For reasons mentioned above! This new restrictive diet can be a tool for those with disordered eating behaviours (and possibly a full blown eating disorder) to fashionably lose weight under the pretence that they have gluten intolerance. Apart from medical professionals, who is willing or capable of challenging their views and diet? As one of these medical professionals I can tell you it’s not easy.
Responding To thecountyfare’s Article
Nutrition Is A Science…
(One that we have both studied) and it needs to be respected. We need to refer to evidence and studies to form relevant arguments and points as is made clear in the article by thecountyfare.
Frustratingly, even with the structured evidence that science provides, people will continue to have polarised views on what’s healthy and how they should live their lives; shutting down conversations that make them uncomfortable and/or where they are unable to back up their views with anything substantial and/or relevant.
Some people will unfortunately always argue science, even when it’s in black and white; a lot of people do not like facing change. As mentioned, science isn’t perfect, nor does it have all the answers…but some people (when approached with new concepts) will always react as if there is some conspiracy taking place.
Most people are perfectly happy to use prescribed medications, despite the fact that almost all the research on them has been carried out by the companies that intend to sell them to us. So calling into question the ethics of researchers in nutritional subjects is a little hypocritical; whatever happened to approaching things carte blanche?
Understandably we should question the motives of the researchers and investigate possible vested interests, but it would be grossly unfair to dismiss out of hand decades of research just because of who may or may not have picked up the cheque.
‘Weight Loss And Feeling Better’
The ‘Paleo guy’ would have undoubtedly lost weight on a diet that was low kcal, low-fat, high protein and low G.I, and we’re sure he would have felt better (losing 60lbs would do that!). However, the concept of feeling better than 10 years ago is such an ambiguous and subjective statement that it’s rendered almost meaningless; with the foibles that memory has, you can’t compare the state of your mind in this way over the course of one month let alone a decade. This is one reason why subjective measurements in research are always considered second rate to physiological measurements, i.e. blood tests. This is linked to the ‘nocebo effect’ that was discussed.
‘I’m Getting Everything I Need’
thecountyfare makes another good point, unless this guy has blood tests or strictly monitors and analyses his diet, he cannot evaluate his overall diet/health with confidence- no one can. In the UK, the National Health Service (NHS) will only request vitamin and mineral analysis on an ‘as needs basis’ and only if you can convince your GP, so the majority of people will not have these types of tests; you’ll be lucky if they go for routine blood tests. Unfortunately people seem to take matters into their own hands and do their best to avoid healthcare professionals and needles!
Now some people may use nutritional databases such as the USDA one here and calculate their nutritional intake, but this is very time consuming and to further complicate matters there is the issue of bioavailability and optimal absorption; put simply, this is how well micronutrients are digested and made available for use.
The body tightly regulates the absorption of some to prevent toxicity, which can mean high dose supplementation is a waste of money. Even from food sources micronutrient absorption can be impaired by competing micronutrients and other foodstuffs, not to mention that some micronutrients come in different forms depending on the food they are found in and these forms are absorbed at different rates. To call the matter complex is an understatement but it does highlight why you can’t be blasé when claiming ‘to get all you need’.
Gluten Free Promotion
The science is there to support why people need to be GF (as a coeliac) but not as a ‘gluten free fad’. As it stands, people’s lives seem to be governed by GF propaganda and overpriced GF products; there is no need for this. As thecountyfare mentioned, there seems to be a monopoly over who sells what. It’s ridiculous how many GF products are now available; it’s true, companies saw a market and now they are cashing in… on people’s concerns and laziness.
These companies have also started producing products that are not only GF but dairy free (DF), egg free (EF) and/or Vegan (V) as well, in the hope that their products will ‘appear’ even healthier. Unfortunately some of us might not realise that something that is GF, DF, EF and/or V can still be unhealthy and inappropriate. This can confuse the matter and adds to these ‘diet trends’.
Living in ignorance about your health isn’t bliss and nor is pretending you have all the answers. For example, a simple blood test for coeliac disease could provide a diagnosis (if someone has enough antibodies), but the gold standard is still a bowel biopsy (at least in the UK).
For those that have symptoms and are concerned, the worst course of action (as with all health conditions) is to self-diagnose and self-treat, due to the risk of misdiagnosis, e.g. putting yourself on a GF diet for six months and then paying a visit to your doctor to request blood tests. This would be an exercise in futility; blood tests would show a skewed result because there would be fewer antibodies present, giving you a false negative; this might result in you having a more cavalier approach to a GF diet, rather than the total exclusion required.
We’re not saying gluten intolerances do not exist and the studies mentioned in the article raise some interesting points (especially regarding FODMAPs), people just need to seek their healthcare professional’s advice. Unfortunately, using Google (other search engines are also available!), fad diet books or your own hypochondria to base health decisions on is not a great idea. We agree that it’s incredibly irritating and potentially harmful if these people start spreading their misguided information regarding nutrition; this is where fads of eating 100 bananas a day come from. We wish people would stop producing ‘trendy diets’ and that celebrities could make do with one less wheelbarrow full of cash and stop endorsing them!
Coeliac disease is a complex topic, and one we won’t go into now; we plan to write about it on our own blog in the future.
Our Closing Thoughts
We would like to mention that we have never advocated a trending ‘gluten free diet’, but we do offer it as a choice through our recipes because as we have mentioned, coeliac disease is a very real condition. The quality of GF products haven’t been the best in the past and everyone should be encouraged to bake/cook from scratch (these are essential life skills for a healthy lifestyle/healthy living) whether you have a food allergy or not.
Adapting any alternative lifestyle (especially going WFPB) requires you to plan ahead; making sure your diet is nutritionally adequate. People need to reflect on the choices they make; are they making informed ones? …What is influencing their decisions?
Every pill, supplement or diet going isn’t necessary going to produce the life-changing results they desire, it may also be inappropriate and isn’t necessarily backed by scientific evidence; although companies like to take snippets from studies sometimes out of context to sell products.
So thecountyfare is right folks, tread with caution indeed.
