Last year, I wrote a blog post about Morgellons Disease, now called Unexplained Dermopathy by the CDC. I wrote the post in response to a study that had just been published by the Mayo Clinic saying that they had found no evidence of infection or infestation in 107 self-diagnosed Morgellons sufferers, and were thus concluding that Morgellons was not an infectious disease, despite claims to the contrary. This week, the CDC has released a report on the subject, likewise concluding that no infective agent could be identified in person suffering from Morgellons-like symptoms.
Despite the findings of the study, it's unlikely that we've heard the last about Morgellons, as many providers working with Morgellons and patients suffering from Morgellons may view the report with some suspicion. Many Morgellons sufferers feel that the medical establishment is dismissive of their symptoms, and are thus unlikely to interpret the study results as anything but more dismissal.
I myself, however, was heartened by some of the interviews the reporters gave. Study co-author Felicia Goldstein has said, 'The absence of evidence is not evidence of absence,' and Mark Eberhard, director of the division of parasitic diseases and malaria at the CDC, has said, 'It's a negative, but it really limits and narrows down the field of possibilities. By removing a couple of the big players - infections and the environment - that still leaves some wide open territory about what could be the causes.' Clearly, people are suffering - the question is, 'From what?' As a naturopathic physician, I believe it is important to acknowledge the legitimate suffering of our patients, listen openly, and help to relieve that suffering.

What is Strontium?
Strontium is probably the most-heavily studied mineral
treatment for osteoporosis that you’ve never heard of, unless you’re a
naturopathic doctor or a geriatrician. In the discussion of osteoporosis
prevention and treatment, we hear a lot about calcium, magnesium, vitamin D,
and vitamin K, but rarely do we hear about strontium – most of us probably
couldn’t even find it on a periodic table if we had to. Even so, strontium has
a pretty extensive amount of research behind it, and has been shown to not only
improve bone density (as measured on a DXA scan), but it has also been shown to
help reduce the risk of fracture, which, when you’re dealing with osteoporosis,
is the most important thing to see.
So to start with, what is strontium? Strontium is a trace
mineral that occurs naturally in the diet, albeit in small amounts, typically
about 1-3 mg/day. Typical sources of strontium are whole grains, leafy greens,
and root vegetables, i.e. all the usual suspects. As a supplement, however,
strontium is typically dosed at a much higher level, in a range of 450mg to 2g
per day. Any time a nutrient is dosed at a level much higher than it would
occur in the diet naturally, science studies it extensively, to verify that
it’s both safe and effective, and strontium is no exception.
Some older articles seemed to suggest some safety issues
about strontium, suggesting that strontium might contribute to bone growth
disorders. In one case, young rats fed a high strontium diet developed bone mineralization defects, and in another, children living in a part of Turkey
with high levels of strontium in the soil (and thus food) demonstrated
higher-than-normal incidence of rickets. In both situations, however, the bone
disorders seem to have been related to the respective diets’ relatively low
levels of calcium. Since then, multiple studies have confirmed that patients
taking high doses of strontium, who are eating otherwise balanced diets or
taking supplemental calcium, do not develop bone disorders. Indeed, patients
taking high levels of strontium for the prevention or treatment of osteoporosis
have normal bone structure.
So what about it’s efficacy? In the early 2000’s, two major
studies were undertaken to assess whether strontium renalate (a prescription
form of strontium used in several European research studies) was an effective
treatment for osteoporosis, including its ability to increase bone mineral
density (as measured on a DXA scan) as well as its ability to reduce incidence
of fractures. The Spinal Osteoporosis Therapeutic Intervention (SOTI) trial and
the Treatment of Peripheral Osteoporosis (TROPOS) trials both found that
strontium renalate increased bone mineral density and reduced fracture risk in
postmenopausal women with osteoporosis, with some of the greatest treatment
effect noted in women over 80 years of age (1, 2, 3), who are at the greatest risk of
fracture. Data from these studies and other sources prompted the Cochrane Review to award strontium renalate with silver level evidence in the prevention of vertebral and nonvertebral fractures, as well increasing bone mineral density. These two studies demonstrated positive results over relatively short
periods of time (three and five years, respectively), and so questions remained
about their long-term efficacy. This last year, however, an extension study of
women involved in the SOTI and TROPOS studies indicated that strontium renalate
continued to support increases in bone mineral density and a strong reduction in risk of fracture over a ten-year period with minimal side effects, thus
establishing it’s safety and efficacy over long periods of time.
Sounds great right? Well, here’s the catch. Strontium
renalate is not currently approved for use in the United States. The biochemist
in me would believe that strontium should be active in forms other than this
one – i.e. that strontium chelate, strontium citrate, and other would have
similar activity. However, this being science, we need evidence, and
unfortunately, there’s not a lot out there on other forms of strontium. I found
one study stating that dietary strontium increased bone mineral density in an animal model, suggesting that other forms of strontium may have beneficial
effects. On the other hand, I found another study which showed that
strontium renalate was far more effective than strontium chloride at delivering
strontium to the bone; while this doesn’t tell us for sure about strontium
citrate, chelate, etc, it certainly suggests that strontium’s efficacy depends
highly on the form it is delivered in.
So the take-home message is this: strontium renalate is
effective in the treatment of osteoporosis, but other forms may not be. The
paucity of evidence regarding other forms of strontium makes it very hard to
make any statements about their effects, beyond speculation or educated guesses
– I had my druthers, I’d be calling for research into strontium citrate,
strontium chelate, and other forms. If you’re a health care consumer and have
been diagnosed with osteoporosis or osteopenia, make sure you’re getting
regular DXA scans – other forms of strontium may be effective, but the ultimate
test is going to be your own bone density. Continue to follow the tried and
true prevention methods, such as calcium and vitamin D supplementation, and
engaging in weight-bearing exercise.

Getting Sleepy With Dr Oz
In my practice in Oakland, it seemed as though none of my patients was sleeping enough. Most were getting under six hours a night, many as few as four. I would often joke that I could base my practice entirely around two things - explaining to people what the labs their other doctors have ordered actually mean, and helping people to get some sleep.
Here in Washington DC, where I shadow a cardiologist, we discuss sleep apnea with nearly everyone, as it's rampant in cardiac patients, where it contributes to high blood pressure, obesity, and other chronic problems.
Most of what I would tell my patients involved eating dinner earlier in the evening, turning the computer/TV off at least 45 minutes before bed, keeping the bedroom clear of distractions, and other 'sleep hygiene' practices. This week, Dr Oz, that naturopathic doctor in a medical doctor's clothing, has written an article outlining recommendations for getting better sleep. It's comprehensive, clear, and I daresay I couldn't have done a better job myself. If you're having trouble getting enough sleep, or if anyone you know is, I highly recommend this article. Read on, dear readers, and sleep peacefully.

A Tale of Two Diets, Part 4: The Conclusions
Tom
You’d be hard-pressed to find anyone who didn’t know that
McDonald’s and other fast food is bad for you, but we rarely recognize the
scope of the problem. In writing this piece, I tried to imagine reasonable
portion sizes – if you look back, Tom doesn’t do anything outlandish like eat a
second Big Mac, or a whole large pizza, and yet he clocks in at over 4000
calories for the day. If anything, this should tell us how unhealthy the food
at fast food chains is.
As I pointed out, the nutritional content of the food is
heavily weighted to saturated fat, sugar, sodium and excessive protein. And
yet, despite the profusion of these types of nutrients, Tom’s diet is almost
totally bereft of fiber, not to mention most vitamins and minerals.
I’ve also tried to show that a diet like this presents
health problems in both the short term and the long term. The long term effects
of diet, like diabetes, hypertension, heart attack, cancers, etc, sometimes
seem distant and unreal, and so it’s not always on the forefront of our minds
when we make meal choices. The short term effects, however, are also present –
we just don’t always link the causes with their effects. (I once had a patient
who had digestive complaints and insomnia, but couldn’t seem to figure it out –
when we asked about his diet, he said he ate consumed mainly Hot Pockets and
Mountain Dew.) As you can see in this story, Tom’s high intake of refined sugar
and caffeine causes his energy to spike and plummet throughout the day,
ultimately leaving him exhausted but unable to sleep. I hope this has helped to bring home the problems with a
poor diet.
Paul
So let’s talk about Paul’s diet. Paul is eating a very well
balanced diet – it’s low in saturated fat, low in sugar, high in fiber, high in
protein, and it favors health-promoting unsaturated fats. He clocks in at just
under 2000 calories for the day, and as estimating his caloric intake was a
little more challenging than Tom’s, I think he’s pretty much right on the money
with the amount of food he’s eating throughout the day, and the balance he’s
chosen.
His intake of micronutrients is excellent, and Paul’s
getting a full spectrum of vitamins and minerals. I didn’t focus heavily on
these throughout the discussion, but Paul’s plant-based diet puts him in very
good standing to meet his daily needs. Additionally, his consumption of
non-nutrient health promoting compounds is high – things like probiotics,
plant-based antioxidants, sulfurophane, etc. While these are not technically
nutrients, they have excellent health-promoting actions. In all, Paul is eating
a well-rounded diet that is helping him to live a happy life in the present and
is also working to prevent future disease. Paul should be very pleased with himself.

A Tale of Two Diets, Part 3: Dinner and Evening
We now return to our story, already in progress. You may
recall that Tom has been eating largely fast food all day, whereas Paul has
been eating a pretty varied diet, supplying him with a whole host of nutrients
and health-boosting compounds.
4:30pm – The end of
the workday is approaching, and both men are starting to get a bit hungry.
Paul has packed hummus and carrots and snacks on them as he
winds down at work.
- The
combination of unsaturated fats and fiber in hummus makes it a great snack
choice. On the one hand, it’s very healthy, as it contains significant amounts
of both of these components, and on the other, it’s satisfying, with the
combination of fat and fiber creating a sense of satiety that lasts.
- And of course, let’s not forget the carrots! Carrots are best known for their
beta-carotene content, but also supply some fiber and a reasonable amount of
minerals.
Tom decides to power through the late afternoon. He’s fairly
stressed out, due in part to the caffeine he’s consumed throughout the day, but
also due to his blood sugar, which is dropping yet again, and quickly.
The tally after a late afternoon snack:
Paul – Calories: 1295, Saturated fat: 11.4g, Sugar: 45.1g,
Sodium: 637mg, Fiber: 28.7g, Protein: 47g
Tom – Calories: 2410, Saturated fat: 29.5g, Sugar: 122g,
Sodium: 2610mg, Fiber: 12g, Protein: 68g
7:00pm – It’s dinner
time, and our heroes sit down for their respective meals.
Tom is tired after work, and so has ordered a large pepperoni
pizza from Pizza Hut. He sits down in front of the TV, opens a Budweiser and
prepares to chill out. He’s not eating the whole pizza, of course, but he’s
feeling hungry and in need of something filling, so he eats half of it, finishing the first three slices quickly, and going back for the fourth a little later on in the evening. Over
the course of the next few hours, he has another beer before calling it an
evening.
- Of
course, the same issues with sugar, saturated fat, and sodium still apply, but
let’s move beyond that and talk about variety in Tom’s diet. Each of Tom’s
meals today has consisted of a variation on the theme of bread and meat, with
cheese being added to both lunch and dinner. While there is certainly a place
in the world for each one of these things, when they comprise the backbone of
every meal, we start to run into issues. As we’ll see when the tally is
counted, Tom’s diet continues to be weighted heavily towards lots of calories,
saturated fat, and sugar, at the expense of fiber, vitamins and minerals.
- Additionally, though protein is an
important part of the diet, especially early in the day, Tom’s diet is
extremely high in protein, almost to a fault. A diet this high in protein
starts to tax the kidneys quite heavily, as they are the part of the body that
eliminates nitrogen, an element that primarily enters the diet through protein.
This evening’s pizza in particular doubled his day’s protein intake, putting
his total protein intake at a whopping 130g (the FDA recommends 50g per day).
Paul has headed home, likewise tired, but feeling alright.
He’s not feeling up to making much in the way of dinner tonight, as he made
curry last night, so on his way home, he picks up a salmon fillet (which he
will grill on his trusty George Foreman), a bunch of broccoli (which he’ll
steam), some soy-ginger dressing for the broccoli, and a bottle of red wine (of
which he’ll have a glass). Paul’s dinner is remarkably easy, yet nutritious.
- Fish,
and in particular salmon, is a great source of omega-3 fatty acids, a group of
very healthy unsaturated fats that help protect the heart, and are
anti-inflammatory. The heat from grilling damages these fats somewhat, but
their benefit is still present, and they’re a far sight better than saturated
fat. Sushi is probably the healthiest way to eat fish, but Paul doesn’t feel
like sushi tonight.
- The
broccoli provides the ever-popular fiber, but also provides a variety of
compounds that help the liver detoxify efficiently. Sulforaphane, a component
of broccoli, not only encourages the liver to produce detoxifying enzymes, but
it also has been shown to have a direct cancer-preventing/tumor-suppressing
activity. All other members of the Brassica species, including cabbage, kale,
cauliflower and Brussels sprouts have this same activity.
- Paul
decides to buy the salad dressing to make the broccoli a bit more interesting,
and because Paul reads the nutrition labels on the back of the food he buys, he
finds one that is comparatively low in saturated fat and sodium, though they’re
it’s still a significant source of sodium for Paul today.
- Finally,
the wine. Unlike the Budweiser that Tom is drinking, which is low in nutrients,
but high in calories, the red wine that Paul opts for is rich in antioxidants,
just like the green tea he had with breakfast. Consumed in moderation, red wine
provides some notable health benefits, and can be part of a healthy diet, not
to mention the fact that Paul’s appreciation of good wine enriches his life, as
it’s stimulated an interest in traveling to Sonoma Valley as well as Italy, to
learn more about the wineries of the world.
- Paul’s
eating quite a lot of protein today, but as he eats a varied diet, there is not
a lot of concern about this. Additionally, as Paul bikes to and from work, this
extra protein is being put to good use, being broken down for fuel, and being
used to build muscle.
The final count:
Paul – Calories: 1909, Saturated fat: 15.4, Sugar: 56,
Sodium: 1306, Fiber: 32.7, Protein: 97g
Tom – Calories: 4022, Saturated fat: 53.5g, Sugar: 142g,
Sodium: 6272mg, Fiber: 20g, Protein: 130g
10:30pm – Paul heads
to bed, having spent the last hour reading last weekend’s newspaper and
drinking chamomile tea. Paul drifts off within a few minutes and sleep soundly
throughout the night.
Tom, however, tries to sleep, but tosses and turns, his mind
racing. He’s exhausted, but he just can’t get to sleep. If we look back on his
day, this shouldn’t surprise us – he’s had two 16 oz lattes and a similarly
sized Coke! While we’ve been talking a lot about the long-term effects of Tom’s
diet, regarding the likelihood that he’ll develop diabetes, heart disease and
other diseases, it’s causing him problems in the short term, preventing him
from sleeping. Tom won’t get to sleep until after midnight tonight, so when
he’s up tomorrow morning, he’ll be groggy, just as he was today.
Tune in again tomorrow to hear me wrap this all up. Until
then…

A Tale of Two Diets, Part 2: Lunch
Welcome to part two of a weeklong series about two men and their radically divergent diets. If you missed last time, you can find it here.
1:00pm – Lunchtime rolls around and both men have an hour to
eat.
Paul has brought his own lunch, and begins to tuck in.
Today, he’s eating leftovers from last night – a bowl of curried lentils and
rice. He’s also brought along an apple and a small salad of lettuce with olive
oil and vinegar dressing, and is washing everything down with water he’s
drinking from the metal canteen he keeps at his desk. Paul’s meal isn’t
elaborate for sure, but it’s filling.
- The
curry dish and apple both supply fiber, which, as I mentioned before, will help
keep Paul feeling full, and will slow the absorption of dietary sugars, thus
keeping his blood sugar steady throughout the afternoon.
- Additionally,
the combination of lentils and rice in the curry dish provides a complete
protein. Here’s what that means – protein is
made up of 20 ‘essential’ amino acids, substances the body needs to
function, but can’t make itself, and which can only come from the diet.
The foods we eat vary in the amount of these amino acids they provide; most
animal products contain all 20 essential amino acids, but many plants provide
only a portion of these amino acids. The combination of beans or lentils and
rice provides all 20 essential amino acids, making it a staple of any
vegetarian diet.
- Though
the lettuce provides little nutritional value itself, the dressing – olive oil
and vinegar – is important. Olive oil is an excellent source of unsaturated
fat (specifically omega-9 fatty acids). Though there’s been an obsession with low-fat foods for some time, there’s
now an increasing trend towards healthier fats, i.e. away from saturated fats towards unsaturated fats. These unsaturated fats have many health benefits, but are
probably best known for helping to prevent heart disease.
- Finally,
let’s talk about the spices in Paul’s curry. You might not know it, but Paul’s
curry is a veritable powerhouse of anti-inflammatory agents. First and foremost
in that category is turmeric, which was long known just for lending the yellow
color to curry, but has since been shown to be a strong inhibitor of the
inflammation-causing COX-2 enzyme, and has been researched for just about
everything from cancer to rheumatoid arthritis. Other curry spices include
ginger, also a COX-2 inhibitor, and cinnamon, which has been shown to help the
body maintain a steady blood sugar level. Many of the other spices promote
healthy digestion, in addition to tasting good.
Additionally, because he’s brought his own lunch, Paul can
eat more slowly, and has plenty of time to digest his meal before returning to
work.
Tom, on the other hand, is going to his usual – McDonald’s.
We’d all like Tom not to go to McDonald’s, but as I said yesterday, Tom likes
his routine. The McDonald’s is busy during lunch hour, so Tom has to wait in
line to get his order taken and has to wait again to get it filled. Between the
walk and the wait, it’s 10:30 before Tom starts eating.
- He
was hungry before walking in, having let his blood sugar drop yet again,
and between the wait and the pressure to get back to work in time, he’s pretty
stressed out when he eats. As a result, Tom’s sympathetic nervous system is
dominant at the moment. The sympathetic nervous system (SNS) is the division of
our nervous system that puts us in a fight or flight mode – when it is
dominant, it increases blood sugar, increases heart rate, and impairs
digestion, all of which are necessary to, for example, run away from a bear or
play a game of soccer. However, as I said, it impairs GI activity, making
digestion and absorption of nutrients more difficult. The parasympathetic
nervous system, the SNS’s counterpart, is best known for promoting a ‘rest and
digest’ mode. If you’re wondering what a parasympathetic state looks like, imagine Paul right now.
- Without
going into great detail about Tom’s lunch, it’s essentially more of the same –
more saturated fat, more sugar, and more sodium.
For lunch, Tom’s having a Big Mac, medium fries, and medium Coke. He leaves
still feeling a little hungry, and so he grabs a small bag of chips on the way
back to the office, which he’ll eat over the course of the afternoon.
At lunchtime, the score is:
Paul – Calories: 1042, Saturated fat: 9.9g, Sugar: 42.1g,
Sodium: 300mg, Fiber: 20.7, Protein: 40g
Tom – Calories: 2410, Saturated fat: 29.5g, Sugar: 122g,
Sodium: 2610mg, Fiber: 12g, Protein: 68g
So we could almost stop now. Tom is already well above and
beyond a recommended daily caloric intake and sodium intake, has hit a full
150% of the recommended saturated fat intake, and has consumed about three
times as much sugar as Paul. Meanwhile, Paul has gotten antioxidants,
probiotics, anti-inflammatory herbs, fiber and all sorts of other good things
in his diet. I’m going to carry on and talk about the evening because Paul has
a few more things to teach us as we head towards the end of the day, and we
still have yet to explain why Tom woke so groggy this morning… Tune in next
time!

A Tale of Two Diets, Part 1: Breakfast
This week, I’m presenting a serialized version of a talk I’m
giving this weekend, a talk that will compare two diets and their
health-promoting and health-defeating properties. The talk will follow two men,
Paul and Tom, throughout their day, cataloguing what they eat and how their
days go. While I generally am not a big advocate of calorie counting, I’m going
to do some basic number crunching this week in order to make a point; mainly,
however, I’m going to focus on the nutritional content of the food each of
these men is eating throughout the day.
I hope you enjoy this little creative endeavor.
7:00 am – Tom wakes up feeling groggy – to understand why
he’s groggy, you’ll have to wait until later in the story. Fortunately, today,
he didn’t hit the snooze alarm too many times. Tom has a fairly regular
regimen, and he does the same thing more or less every day. He’s a pretty
consistent guy and he isn’t a big fan of change. He wanders, bleary-eyed, to
the shower and hopes the water will wake him up a bit.
Paul wakes up at around the same time feeling refreshed
after 8 hours of sleep. He’s also got a pretty consistent routine, and while he
doesn’t spring out of bed, he feels up to taking a 20-minute jog before
breakfast.
8:00 am – Both men are showered and ready to eat.
Paul has a small bowl of yogurt (1/2 cup), almonds (1/2 cup)
and berries (1/2 cup), and washes it down with a cup of green tea. In this
meal, Paul is getting a whole host of health-supporting compounds, starting
with probiotics.
- Probiotics
will help keep Paul’s digestive system working properly, helping him to digest
and absorb his food all day, and helping him fight off anything that might have
come in on his food.
- The
fiber in the nuts and berries will help keep Paul feeling full longer, so he’s
less hungry throughout the day, and, in the long run, will help keep Paul’s
cholesterol down.
- Antioxidants,
found in the berries and the green tea, will help Paul’s liver to breakdown
toxins he might encounter in his environment, will help his immune system fight
off viruses and bacteria, and will help keep his body in good cardiovascular
health.
- Finally,
the substantial serving of protein he’s getting will help him maintain a steady
blood sugar through the morning, so he’ll have enough energy to get through
work without dozing off.
Tom, on the other hand, doesn’t have any food on hand to eat
at home, so he’s going to have to make the first of several trips to McDonald’s
that he’ll make today. Because he’s got a bit of extra time, he’s going for the
hotcakes and sausage this morning, washing it down with a glass of orange juice
and a medium nonfat latte.
- Though
they may taste good initially, the saturated fats in the hotcakes and sausage
will predispose Tom to high cholesterol, obesity and high blood pressure in the
long run.
- The
sugar in the hotcakes and especially the syrup make Tom more likely to develop
diabetes later in life, and will cause Tom more immediate problems later on
today.
- The
sodium in the meal, of course, contributes to Tom developing high blood
pressure.
- And
finally, Tom’s gotten nearly no antioxidants! This is going to make it
especially hard for Tom’s body to deal with the stresses he’s going to suffer
as a result of this breakfast.
A plus for Tom’s meal is that he is getting a good amount of
protein in his meal, but it’s outweighed by the massive amounts of fat, sugar
and sodium.
The tally so far:
Paul – Calories: 410, Saturated fat: 5.8g, Sugar: 20g,
Sodium: 174mg, Fiber: 7.2g, Protein: 26g
Tom – Calories: 1000, Saturated fat: 10g, Sugar: 60g,
Sodium: 1160mg, Fiber: 3g, Protein: 27g
9:00am – Both men arrive at work. Paul is relaxed and
motivated, having biked to work. Tom arrives feeling pretty amped up and ready
to go, having finished his morning coffee.
11:30am – Tom is a little worse for wear. The pancakes and
coffee that he had for breakfast caused his blood sugar to rise very rapidly,
which made him feel great in the short run, but a few hours later, his blood
sugar is plummeting. He’s starting to feel restless and is having difficultly
paying attention to his work. He’s got a big report due this afternoon, and so
when someone at the office says they’re going on a coffee run, he’s first in
line with his order – another latte.
Paul is also starting to feel a bit peckish, but his blood
sugar has remained relatively steady this morning, so he doesn’t need to eat
quite as much, and happily eats a handful of almonds.
The continuing tally:
Paul – Calories: 575, Saturated fat: 6.9g, Sugar: 21.1g,
Sodium: 174mg, Fiber: 10.7g, Protein: 33g
Tom – Calories: 1180, Saturated fat: 16g, Sugar: 73g,
Sodium: 1290mg, Fiber: 3g, Protein: 37g
So that’s the morning! As you can see, Tom hit 1000 calories
at breakfast alone. While most Americans eat more than 2000 calories in a day,
2000-2500 is a good benchmark to assess an average ‘healthy’ American diet.
Additionally troubling is that, at 16g of saturated fat, Tom is already at 80%
of the recommended daily intake. Though there is no defined daily intake of
sugar itself, you can see here that Tom has consumed nearly four times as much
sugar as Paul, and about a quarter as much fiber.
