The Benefits of a Gluten Free Diet

Is gluten really Public Enemy #1?  Many seem to regard it as a toxic agent that causes a variety of symptoms.  Restaurants and supermarkets offer a wide variety of gluten-free foods.  Years ago, physicians advised a gluten-free diet only for individuals who had celiac disease (CD), which is an autoimmune disease that largely affects the small intestine.  If a celiac patient wades back into gluten territory, then his or her intestine will revolt.  I care for a few of these folks, but they are but a slim fraction of my patients who are shunning gluten.  

Gluten are proteins contained in wheat and other grains.   Many adherents of a gluten-free diet believe that avoiding gluten is a more healthful dietary choice.   There is no actual test to confirm gluten intolerance, but many patients feel better on this diet. . Why should it matter if an individual chooses to avoid gluten?  After all, there’s no risk here?  In fact, avoiding gluten can lead to vitamin deficiencies and increased exposure to arsenic and mercury.  I’m not suggesting that glutenphobes are at risk of poisoning themselves, but they should make sure that they remain nutritionally sound.


Amber Waves of Grain

  
There are 3 conditions with scientific support for avoiding gluten.

Celiac Disease:  Without question, gluten is the enemy

Gluten Intolerance (GI): A murkier condition that likely exists but may be over-diagnosed.  The relationship between gluten and the symptoms attributed to GI, such as abdominal pain, brain fog, bloating, fatigue, headaches and bowel irregularity, is tenuous.   Many other medical conditions beyond gluten exposure might be responsible.  There is no accurate test for GI.

Wheat Allergy:  This is a food allergy.   True food allergies (not intolerances) are very rare, although many patients mistakenly believe they are suffering from them..  Allergic features include hives, wheezing, itching and difficulty breathing. 

Most gluten avoiders do not fall within the above categories.  They avoid gluten because they feel better on the diet or believe that it is serving their health interests.  We all do stuff that we believe benefits us, even if there is no scientific support.  If you feel better avoiding a food item, then of course you should do so.

We are a free country and we have the right to be gluten-free.   But, let’s make sure that we separate fact from myth, or put another way, separate the wheat from the chaff.

  1. I feel better eating less gluten. I think our American diet is too high in gluten but is somewhat hard to cut back and maintain ( for me)

Becoming a Part-Time Physician

Next month my schedule will change.  I will henceforth be off on Fridays with my work week truncated to Monday through Thursday.   I am excited to be enjoying a long weekend every weekend.  And while the schedule change is relatively minor, this event does feel like an important career moment for me.  It is the first step on a journey that will ultimately lead beyond my professional career.  It is this recognition that makes this modest schedule modification more significant than one would think it deserves.  As some readers know,   my current employed position has been a dream job for me.   Prior to this, I was in a small private practice, which I loved, but was much more challenging professionally and personally.   My partner and I ran the business.   Working nights, weekends and holidays were routine for decades.   On an on-call night, if I slept  through until morning, I felt as if I had won the lottery.   And w...

When Should Doctors Retire?

I am asked with some regularity whether I am aiming to retire in the near term.  Years ago, I never received such inquiries.  Why now?   Might it be because my coiffure and goatee – although finely-manicured – has long entered the gray area?  Could it be because many other even younger physicians have given up their stethoscopes for lives of leisure? (Hopefully, my inquiring patients are not suspecting me of professional performance lapses!) Interestingly, a nurse in my office recently approached me and asked me sotto voce that she heard I was retiring.    “Interesting,” I remarked.   Since I was unaware of this retirement news, I asked her when would be my last day at work.   I have no idea where this erroneous rumor originated from.   I requested that my nurse-friend contact her flawed intel source and set him or her straight.   Retirement might seem tempting to me as I have so many other interests.   Indeed, reading and ...

Will Smarter Lawyers End Frivolous Lawsuits?

How do you know if a lawyer is any good?  Of course, they've all passed the bar, but now their profession is lowering it.  While most of us strive for excellence, and raise our children to value this virtue, prominent legal educators are establishing a new quality intitiative for their profession.  Who says that lawyers can't reform themselves?  Perhaps, we physicians can follow their bold example and raise the credentials of our pre-medical students.  I’ll present the facts. You be the judge. I have written a dozen posts on tort reform on this blog, which always generate spirited and adversarial retorts from attorneys and their supporters. They accuse me and other tort reform advocates of carrying water for insurance companies. They repeatedly point out that I know nothing about the legal system and are unqualified to opine on its flaws. They deride me when I argue that effective tort reform would reduce the practice of defensive medicine, despite the re...
