That’s Not A Methylation Issue…

This is. 

 I think we’re all going to scream when the next patient says, ‘I’ve got an MTHFR’, right?!

Congratulations, I want to say, because you would be in much more serious trouble if you didn’t have a copy…

‘Oh, sorry, you mean you have a mutation on at least one allele encoding for the MTHFR enzyme…Oh, I hate to tell you but contrary to popular (online) belief, you’re not special.’

I’ve Had a Gut Full of Glutamine!

“I always give some Glutamine to heal their leaky gut”

Cue pained expression on my face.  No, I’m not a fan.  I take that back, I have no problem with the amino acid itself and I’m still in awe of its incredible multifaceted role in the gut.  What I do have a giant issue with is the mismatch between everything we are being told Glutamine is going to help our patients with, and the dosages that apparently will do that, and the reality.   I know, I’m attacking the Holy Grail of Gut Health 101….right? But it’s time to set the record straight. Firstly, where’s the evidence at in terms of Glutamine interventions in GIT pathology, particularly in relation to reducing excessive intestinal permeability and improving lining integrity  Well if you’re a rat – Good news!  Rats’ GITs have a greater dependence on Glutamine than ours, a deficiency of this amino produces clear reproducible negative effects and supplementation fixes these brilliantly!

But if you’re treating humans not rats – well – the evidence & the case for Glutamine for the Gut is not so straight forward or impressive. (more…)

Iodine – Questions & Confusion Need Clearing Up!

That’s me…always questioning the ‘status quo’ and Iodine is  the perfect example!  The interview I did on this important subject with Andrew Whitfield-Cook from FxMedicine, covers a lot of key areas of confusion & underscores why it’s so critical all health practitioners get clarity on this topic. ‘It’s just a matter of geography’.

You know, I say to people, we can make vitamins ourselves, we can get all sorts of  other organisms including animals, bacteria and plants to make vitamins for us, and then eat those…but minerals…our source of minerals…well it all comes down to the rocks and the soil our food itself is grown or fed on.  And iodine is profoundly influenced by these factors. (more…)

Batmania here I come…

No, I haven’t gone crazy for the ‘caped crusader’… but I thought that would get your attention…. oh look it did! 😉
I’m off to Melbourne for the ACNEM Conference May 5-6th and Batmania was one of the interim names of this very cool and happenin’ town before it became known as Melbourne in 1837! Things have certainly changed in nutrition and the environment since then and as practitioners we now need to address sometimes very complex dynamics between genes, gut, nutrition and environmental health.  Which, luckily enough this conference is all about!
This year’s theme for ACNEM is Health for Life – Mastering the Integrated Approach. 
I am fortunate to be included in the exceptional speaker line-up (thanks for lovely sentiments many of you have expressed so far about that 🙂 ) I am presenting on ageing..which many of you know that I am suddenly now very interested in…getting old and all.


Iodine Deficiency May Impair Ability to Conceive…Who’d Have Thought!

“Researchers followed more than 500 women trying to conceive over about five years and found that, overall, those with moderate to severe iodine deficiency had 46% lower odds, per cycle, of becoming pregnant.”

All researchers dream of generating the kind of results that are ground-breaking but sometimes you read about the latest study’s findings and you  think, ‘Really, you spent all your time & cleverness for years on this and that’s all you have to show for it!’ Like the study that finally confirmed dog’s can feel empathy (at last thank goodness …phew…cos I had my doubts until they crunched the numbers!)

So too a study published this month on the possibility that iodine deficiency is common in women trying to conceive in developed countries and may be connected to increasing fertility issues.

Stop press!  I know…that made you spill your coffee! (more…)

Breaking Wind News – Tracked Straight to Your Phone!

Is this the way of the future for health practitioners interested in patients’ digestion…?

“The team developed an ingestible electronic capsule to monitor gas levels in the human gut. When it’s paired with a pocket-sized receiver and a mobile phone app, the pill reports tail-wind conditions in real time as it passes from the stomach to the colon…The authors are optimistic that the capsule’s gas readings can help clear the air over the inner workings of our intricate innards and the multitudes of microbes they contain. Such fume data could clarify the conditions of each section of the gut, what microbes are up to, and which foods may cause problems in the system. “ (more…)

Is Your GP Doing it Tough Right Now?

If you receive the free Medical Observer newsfeeds you’ll know what I’m talking about.  Here are some recent headlines:

I stand accused of rorting Medicare.  This is what it’s like

A GP is sued after doing everything right — except her notes 

After-hours funding shakeup

‘We’re becoming unviable,’ says GP hit with $22K e-PIP repayment

This Christmas I wish for doctors to feel valued again

So the answer is, probably.  Tales direct from the trenches that I hear from GPs, suggest it is increasingly difficult to make a living without adhering to a crazy volume of <10min appts, without being sued (too often) or dragged in front of AMA or APRHA. I hear them and know that the increased pressure is coming from multiple angles and I think it is very sad that previously such a respected and valued role in society appears to be ‘losing its value’.  Don’t get me wrong, I don’t agree with the old ‘Doctor as God’ model and think it ‘s very unhealthy actually for patients, but I feel like GPs with all their extensive training, knowledge and expertise are in urgent need of an Oprahesque ‘new dawn’!  (more…)

The Rachel Arthur Mentorship Program Honour Roll for 2017

Recognise your own name or someone else’s on this list?

Dear 2017 Group Minties aka Mentees.   I have always struggled with the term, ‘mentees’…seems too American or something and this morning when I was out walking, I had a light-bulb moment – I am proposing a re-branding to something much closer to home (!)… I propose we rename you Minties!! Because you are always fresh and you give me & your fellow Minties always something; cases, questions, clinical conundrums, ethical dilemmas,  every month to seriously get our teeth stuck into!  Cheesy but true 😉

Congratulations on completing your full year of group mentoring – and if this is your 2nd, your 3rd even your 4th year then I bow to you even more deeply.

Thank you for including me on your support team and entrusting me with helping you grow & develop as exceptional practitioners.

You should  be celebrated for your commitment to your own learning & your endeavour to always improve your knowledge and skills. (more…)

So You Think You Know How to Treat Iron Deficiency?

And then you don’t, right? Because if my experience is anything to go by, there are some patients that just don’t respond to the usual iron repletion strategies. Depending on how low their ferritin is, this can then precipitate ‘practitioner panic’ (we’ve all had it right?!) where we’re inclined to go higher & higher with the dose and number of doses per day. Typically, this also fails. I hear about this from other practitioners all the time and I see the ‘normal’ doses of iron sneaking up and up.  Remember the days when we couldn’t get a non-pharmacy supplement with over 5mg elemental iron in it and now we have > 20mg?  But still, I hear you say, this fades into insignificance when you think about the standard medical model for iron correction which provides 100-200mg/day and you’re right. 

Gee… after hundreds of years of knowing about this deficiency and being the most common deficiency word-wide, you’d think we had our supplemental regime nailed.  

But that’s where you’d be wrong. (more…)

Sunshine Doesn’t Come In A Capsule..Last Time I Checked

Have you been a bit vitamin D trigger happy?  Does a patient’s low blood 25(OH)D test result have you reaching for a vitamin D supplement like the rest of us?  Yes…you might need to listen up then. Sunshine doesn’t come in a bottle.  That’s right, if your patient’s problem stems from inadequate sun exposure, have a guess what the best remedy is.  I’m not meaning to sound flippant but I think in all my ‘complex highbrow nutritional understanding’, occasionally (ahem), I have lost sight of the simple truths. (more…)

The Vindication Vibes


I’ve been known to give calcium more attention than most and now I feel vindicated. Serum calcium, of course is not a reflection of your calcium intake, calcium losses nor overall calcium status. In this regard it is totally useless.  But my fixation is about what even slight variations away from healthy levels of this mineral can reveal.

You’ve probably heard me openly scorn the parathyroid glands

“How hard can it be?  These glands have just 1 job: keep the blood calcium in range! Snort!”

And that is exactly why it is so meaningful when this appears to be a ‘big ask’ and the serum calcium slips under 2.2 mmol/L or over 2.45 mmol/L & so potent given the huge chain of physiological reactions that follow from such a small shift – producing profoundly negative effects on vascular dynamics, neurological function etc. (more…)

Are you feeling your AGE?

Saggy skin

Ever got to the end of a day or a week and felt like this?  Or woken up to find your skin looking like this?! Just quietly, me too.  When my son was about 3 he was sitting in the back of my car with my mum (she would have been in her early 70s) and he asked how people get wrinkles.  We told him it was from having a fun life with lots of laughter, to which he replied out loud while still staring intently at my mother’s face, ‘Wow Grandma! You must have had the best life ever!’ I digress.

I personally am not a crusader of anti-ageing (seen my pics recently?!!) but my recent research into effectively reducing Advanced Glycation End-products (AGE) via the diet, to in turn potentially lower both my risk of tuckshop arms AND just about every other disease you can name (cardiometabolic, neurodegenerative, psychiatric, malignant, you name it), got me sitting up and paying attention!

This is Why I Love My Job!

Untitled design

On Sunday there were deafening bells going off in my brain. By Monday they were going off in 11 others.

Alessandra: “Holy s#*t this has just ticked so many boxes for a couple of Rx resistant patients. Thank you!”

Tess: “Me too – finally the gut and pain connection explained” 

Let’s Stop Normalising Abnormal Breasts

Breast boxer

Let’s play a little word association game:

I say ‘Fibroids’ – you say, ‘Oestrogen’.  

I say ‘Cyclic Breast Pain’ and you say, ‘Ouch!’ [because it just slipped out] but then you say, ‘Prolactin’, right?  Me too. 

Prolactin driven breast pain’s most characteristic form is the premenstrual ‘oh my goodness get these off me!!’ kind, with patients experiencing anything from burning, aching, bruised feelings and acute hypersensitivity to touch, which builds in intensity for days leading up to their bleed. Of course cyclic mastalgia can progress to being full-time mastalgia in women whose breasts start to exhibit structural tissue change in the form of cysts, fibrosis and ultimately fibrocystic breast disease.  If you’ve ever experienced even a day of mastalgia it is truly hard to conceive there are so many women (about 50% of premenopausal women!!) living with it daily.

Adding to our concerns about this so-called ‘benign breast disease’ (BBD) is that researchers are now certain it’s a significant risk factor for breast cancer, with women with any form of BBD experiencing at least a doubling of risk of a subsequent breast cancer diagnosis, while those women with proliferative BBD exhibiting a risk of 3.5X that of women without BBD.  Castells et al 2015  (more…)

Who Me….Ageing???

Ageing hand

My partner and I have a well rehearsed script whenever he is suffering from man flu, he says, “Am I going to die?” and I say “Yes, just not today.” First world peoples tend to specialise in the denial of several absolutes: like time & death.  As Professor David Cameron-Smith, from the University of Auckland says, ‘old’ is something we always define as ‘other’.  We are not old but we know people who are!  I personally used to define ‘old’ as over 50 until that became rather close and uncomfortable at which point I noticed a completely unconscious increase in the lower limit! Now old is over 75 yrs…and stay tuned for more updates 😉

Similarly none of us are ageing, right? (more…)

Seriously..this $%*# is still happening

Milk the word

Setting: Local cafe

Scenario: Run into friends of friends who join us in the sunshine for a cuppa & we’re discussing the finer details of chai (western version V the real streets of Delhi stuff), tumeric lattes etc etc. as you do.  I comment on how unpleasantly strong I found the cow’s milk in those downtown Delhi chais we had when we were there.

50 something man: Oh I LOVE that – I just LOVE cow’s milk. I drink loads of the stuff.  I used to drink 2L a day but now it’s more like 1L a day.

Me: Seriously?

50 something man:  Absolutely.  Then there’s the cheese as well – I would eat at least 1kg of that a week.  But it’s good for my bones, right?  I have that thing, you know, before osteoporosis…brittle bones. (more…)

Can You Diagnose This Deficiency?

scurvy rash

While I did diagnose this one correctly, I didn’t get 100% in this quiz – Can you? Speaking of the devil, Medscape, has this great little visual quiz to test your knowledge about physical signs & other hidden clues of nutritional deficiencies.

While we all know there can be a lack of specificity when it comes to some deficiency signs…like glossitis…eyeyiyi..naming a nutritional deficiency that doesn’t include this sign would be a tougher question 😉 but what a great reminder of some quirky things you may have forgotten or in fact deficiency features you may not have even known about.

A gem I love and apply frequently, is about zinc the ALP levels…watch out for the that later in the slideshow quiz.

Also note the distinct difference in opinion when it comes to vitamin D adequacy – with Medscape citing blood vitamin D result < 75 nmol/L unequivocally associated with osteoporotic change…in contrast to the …’anything over 50 nmol/L is a bonus’ line we’re being fed here in Aus and NZ! While we may not ever see some of these severe deficiency presentations walking through our doors – you can’t be so sure…given the reported resurfacing of scurvy in good ol’ Sydney just last year!

Is it just me?  I love going back to nutrition 101.  So tomorrow with your cuppa…test yourself and then let us know how you go 😉

No Patch on Iodine Testing



  Whenever I talk to practitioners about thyroid health, like I recently did at MINDD, I can guarantee I’m going to get 2 questions:

  1. Shouldn’t we aim for the high iodine intake of Japanese?
  2. Can we use the patch test for testing iodine levels in our patients?

I am so glad you asked.  The answers are no and no.

I am a nutter for minerals and iodine just won’t go away right now.  Too little = a problem, too much = often the same problems. To boot we are faced with radically contrasting views on assessment and dosage and just about everything iodine related. It’s not you – it’s iodine.  Trust me it’s a complex little mineral that requires some extra thought and caution.  If you imagine the Japanese have no thyroid problems – correct that big myth right now by reading this scientific paper that refers to health problems that result from too much dietary iodine.  It also explains that the typical first step in treating hypothyroidism in Japan is to reduce their iodine intake!

Joining the Campfire Conversation


So you’ve heard part of that BIMA story…now here’s the rest. To be honest, I was pretty surprised to win anything given I’ve spent the last 20 years ‘agitating’, challenging the misinformation and strongholds of the big companies etc. Funnily enough, in my post award ceremony interview, my interviewer dished up the biggest compliment of the evening when he said, “Rachel, we all know you can’t be bought!” 

Nutritional & naturopathic medicine is an exciting dynamic field that is growing its evidence base every day but we need to be vigilant about our sources of information, their credibility etc.  I know that what motivates me the most to share what I know is the desperate need for independent voices, free from commercial bias that can help us move our medicine forward on solid ground.  (more…)
