How To Painlessly Pass A Primary Care Dietary Screening with Flying Colors...

 



Every year when I go in for my annual primary care visit – they give me the 2-item test for fruit and vegetable consumption.  It asks for an estimate of how many servings of fruit and vegetables are consumed every day. I can’t recall the breakpoints my health plan uses but the scale runs from zero servings per day up to ≥ 5.  If you research these screenings, some studies will use half measures (like 2.5 servings if consumption varies between 2 or 3).  Other studies will get very specific about what constitutes a serving.  That can vary from “one small apple” to “one cup of apples” to “a baseball sized portion.”.  My goal with this post is to illustrate how you can pass this screen by eating one complicated but easy to make salad a day.  I will also illustrate how to record recipes easily using a system invented by an engineer.

I have to add the usual disclaimers that I am not advising you to make and eat this salad like I do – only showing what is possible for educational purposes. If you are a vegetarian for example, I expect that you would easily exceed the upper end of the scale.  There are two additional advantages to the salad I eat almost every day – first it is designed to be palatable for people like me who generally do not like the taste of vegetables.  Second, it minimizes spoilage. The only ingredient susceptible is tri-color slaw and carrots and they are usually consumed by the expiration date on the bag.  The other ingredients are either frozen (berries) or have a long shelf life (apples). 

I stopped trying to use lettuce of any type because it often spoiled before the expiration date.  The paternal side of my family were cabbage (and potato) eaters from central Europe.  It took me a while to figure out why – but then it dawned on me – they could preserve barrels of cabbage as sauerkraut and not need any refrigeration.  Cabbage also has endogenous antioxidants and that is also probably why it lasts longer than lettuce.   Sauerkraut also fundamentally changes the taste of cabbage, leading me to think that many of those relatives may have had the same aversion to vegetables that I do.  As an example, I remember my father eating overcooked boiled potatoes as his main vegetable staple while the rest of us were supposed to be eating a broader selection.

There is a taste receptor specific and non-specific genetic component to taste and it has been studied for both vegetables and food-liking or food fussiness.  Cabbage makes the list in several categories.

 

Gene / variant

What it detects

Functional effect

Consequence for vegetables / diet

TAS2R38 — PAV ("taster")

Glucosinolates/isothiocyanates in Brassica (broccoli, sprouts, cabbage, kale); PROP/PTC

High bitter sensitivity; more PAV mRNA expressed in taste cells correlates with stronger perceived bitterness

Greater bitterness → vegetable avoidance; may shift toward sweeter/fattier foods; "tasters" decreased vegetable intake under minimal dietary counseling

TAS2R38 — AVI ("non-taster")

Same compounds

Low/absent bitter perception

Less aversion; largest increases in vegetable intake with intervention

TAS2R38 — heterozygote (PAV/AVI)

Same compounds

Intermediate sensitivity, widest perceptual range

Variable acceptance; intermediate vegetable intake response

TAS2R16

Bitter β-glucosides (broad glycoside ligands)

Two-faced binding pocket giving high specificity across diverse glycosides

Modulates perception of bitter plant glycosides, contributing to bitter-food preference

TAS2R19

Bitter glycosides (e.g., in grapefruit, other plant foods)

Clusters genetically with bitter-food liking traits

Associated with liking of bitter vegetables/foods

Multiple TAS2R loci (GWAS)

Various bitter compounds

Polygenic influence on bitter-taste pathways

Collectively shape bitter-food preferences and metabolic/sensory pathways

Food-fussiness / food-liking heritability

Not receptor-specific

~50% heritable; genetic correlation ~−0.65 between fussiness and vegetable liking

Some children genetically predisposed to reject vegetables independent of a single gene

The implications of the above table seem fairly clear.  If you are one of these folks who prefers fats and sugars to vegetables it seems logical that disguising that taste would make these foods more palatable.  Salt, pepper, sugar and other condiments are commonly used as well as butter.  There are numerous forms of coleslaw made with this shredded slaw mix that add fat, vinegar, and sweetener.  Just a few years ago, I had my first salad with blueberries and that was an eye opener.  I typically use salad dressing to disguise the vegetable taste, but blueberries worked very well.  That is one of the driving forces for the salad I will reveal below.

The other driving force is also genetics.  Several years ago, I learned that I have a risk genotype for pancreatic cancer as well as being in the 100th percentile for polygenic risk for amyotrophic lateral sclerosis (ALS).  I would like to try to avoid both of those illnesses if possible.  How and whether or not either of those genotypes get expressed is still a research question.  The answer can only be approximated by epidemiological studies and the results are conflicting.  In terms of exercise, it probably reduces cancer risk but the ALS risk is an open question.  Contact sports and in some cases high exertion athletics can increase risk.  In other cases, non-contact exercise at any level does not seem to have an impact.  Dietary effects on cancer and cardiovascular disease are more well known and the source of recommendations for non-processed fruits and vegetables.  In terms of ALS – higher premorbid intake of fat, trans fat, and cholesterol were higher in a group who developed ALS. Fruit and vegetable intake reduced the risk by 34%.  In a Mendelian randomization study (genotype risk concentration) oily fish, fresh fruit, coffee intake reduced the risk.  There is no definitive prevention path suggested by the studies done so far only the recommendation for larger intervention-based studies.  With current genotyping methods those studies can be done on a pool of subjects with concentrated ALS risk.

At any rate, general dietary guidelines suggest that fruits and vegetables are a critical component of the diet with certain other common components (high added sugar, high saturated fat, trans fat, cholesterol, alcohol) - red flagged.   The dietary landscape has been more confused than ever over the past 2 years based on political misinformation. Against that backdrop I present my personal solution (again not a recommendation to you or medical advice) that allows me to both pass my primary care physician’s fruit and vegetable screening and reassure myself that I can ingest a palatable meal that is probably good for my health.  The salad is also designed to be cost effective since one of the main concerns with fresh produce is how long it will last before it is discarded.

The blueberry salad that started all of this was mixed salad greens, blueberries, and a vinaigrette dressing.  I have not had much luck with mixed greens or even lettuce in my refrigerator.  They generally deteriorate well before the best by date and rapidly discolor.  I decided to substitute mixed slaw (red cabbage, green cabbage, carrots).  Apples last longer and I decided to add that to the mix.   The recipe is presented in graphic form below.  As you can see this is a combination of 3 vegetables and 4 fruits for a total of 7 per day – all in one bowl. 

 


 


That is my salad that I eat most days of the week.  I don't know if there is a gene that allows for eating the exact same food every day - but if it exists I definitely have it.  The cumulative number of fruits and vegetables at the end of the year is impressive and any spoilage is minimal.  A summary of the possible nutritional benefits is listed in the table below.

Note:  In the above table TEAC, FRAP, and ORAC are all antioxidant assays.

 

The table illustrates this this salad adds fruit and vegetable components that are not generally available form other sources. It is complementary rather than complete nutrition because it lacks protein, several vitamins (B-6, B-12, D, E), minerals (Ca, I Zn, Fe, Se), fats and omega-3 FFA, and caloric density.  Some of these deficiencies can be made up by the additional components of the salad (olive oil in vinaigrette, additional nuts, etc). and additional food groups.  This salad is a niche player in the overall diet – but an important one in supplying necessary antioxidants, fiber, and phytochemicals that are not available elsewhere.  It is designed to avoid processed foods and food wasting.

Psychiatrists and the Nobel Prize

 


The verdict came in a week ago and the Nobel Prize in Physiology or Medicine was awarded to Karl Diesseroth, MD, PhD, Peter Hegemann, PhD and Georg Nagel, PhD.  The award for the discovery and implementation of optogenetics in neuroscience.  This technique is a revolutionary one for neuroscience and this award was expected for some time for these researchers.  Since the Prize was publicized there has been an explosion of images, videos, and social media posts featuring Diesseroth, his colleagues, and family members.  In this age of social media, there are an army of influencers using the story to get views.  For my part, I will just say congratulations.  The story I want to tell here is more about psychiatrists and the Nobel Prize.

Many years ago, when I worked at an acute care hospital, I was the department member who presented unusual grand rounds.  I gave one on the mathematicians Paul Erdös and Kurt Gödel reviewing their accomplishments, creativity, and eccentricities.  I followed it up with a grand rounds on the first psychiatrist to receive a Nobel Prize in 1927 – Julius Wagner-Jauregg.  He discovered the treatment of dementia paralytica (late-stage neurosyphilis) with malaria.  It is important to recall that this form of neurosyphilis made up 10-20% of all asylum care at the time, this was a pre-antibiotic era and at the time late-stage neurosyphilis (or General Paresis of the Insane/GPI) was a uniformly fatal illness. An estimated 30% of this population recovered with malaria inoculation and subsequent treatment of the malaria with quinine.

The downside to the treatment and controversy was the fact that 10-15% of patients died as a result of the malaria. This therapy did not disappear with the advent of the antibiotic era in the 1940s.  Patients were being treated as recently as 1969 with malaria fever therapy (12).

Wagner-Jauregg is described as a psychiatrist, but the training in those days was not standardized. After medical school he trained with a histopathologist, then in a psychiatric clinic for 4 years, and eventually headed a psychiatric clinic at the University of Graz in Austria.  His academic focus there was on goiter, cretinism, and iodine.  He produced 80 publications during his academic career and succeeded two highly regarded psychiatrists in clinics. 

His career was not without controversy.  First, he was a Nazi sympathizer.  His application to that party was denied because his first wife was Jewish.  Second, he promoted eugenics.  Third, he administered electric shocks to soldiers for “malingering” and several of them died leading to a formal inquest.  Fourth, some did not find the malaria therapy of neurosyphilis that impressive probably because the cure was also fatal to a significant number of patients. Like any infectious disease, outcomes depend on host factors and neurosyphilis lead to significant physiological compromise and deconditioning.  Fifth, he was also credited with calling for the iodination of salt to prevent goiter based on his thyroid studies, but subsequent work determined there was no direct connection to that policy being adopted in Austria as it occurred decades after his research and at least 2 other research groups were credited.  He had a problematic personality and believed that the usual rules did not apply to him. Although I find century old personality critiques stretching credibility – I agree with several authors that his accomplishments were overshadowed by the controversies.  The best proof of overshadowing is that most people are not aware of his name or accomplishments – even though he won the Nobel and Freud did not, Freud is more widely known and studied to this day.    

Wagner-Jauregg and Freud were contemporaries.  Freud was 1 year older and at times they influenced each other’s career. Wagner-Jauregg was called upon to write a critique of Freud’s work for an academic appointment and Freud provided expert testimony in a hearing where Wagner-Jauregg was accused of killing shell shocked soldiers with some type of electrotherapy.    From 1925-1938, Freud was nominated 12 times for the Nobel Prize in Physiology or Medicine and once for the Nobel Prize in Literature in 1936 but never won the award. In his biography, Peter Gay writes that Freud thought about the award constantly, hoped to get it, and was disappointed when he did not.

Depending on the author, both Freud and Wagner-Jauregg are written about as neurologists or psychiatrists and Freud is occasionally called a psychologist.  This is because of a lack of uniformity in training and credentialling in the 19th and early 20th century.  When you read about many of these prominent figures you will find that they head neurology and psychiatry clinics interchangeably and in many cases were also neuropathologists, neuroanatomists, and histologists.  A good example if the photo at the top of this post.  It is a photo of Alois Alzheimer (back row 6th from the left) with his colleagues in neurology clinic (title Nervenklinik 1910-1911).  The strict translation is “psychiatric clinic or mental hospital”.  At the time this was in the Munich Psychiatric Clinic headed by Emil Kraepelin.

If we think of criteria to apply to determine if a researcher is a psychiatrist or not dating back to that time, I suggest the following:

1) Physicians who made major contributions to neuropsychiatry prior to the formal establishment of the fields of psychiatry and neurology.   Charcot, Wernicke, Alzheimer, Kraepelin, and Freud practiced across both domains.

2) neuropathologists or neurologists who were also psychiatrists or had a major interest in psychiatry; note that Freud was a Privadozent in neuropathology and Adolph Meyer came to the US to work as a neuropathologist.   António Egas Moniz is typically cited as a neurologist who practiced psychiatry.

3) physicians trained in both neurology and psychiatry.  There were really 2 waves of neuropsychiatry.  In the US practically all psychiatrists before 1935 practiced both and it was revived for military psychiatry in WWII. After graduating from medical school in 1901 von Economo spent a year working in an internal medicine clinic and over the next four years worked at various clinics in Europe with Marie, Kraepelin, Alzheimer, and Oppenheim learning psychiatry, neurology, and hypnosis. He returned to the University of Vienna in 1906 and was appointed Professor of Neurology and Psychiatry in 1921.

4) physicians board certified in psychiatry by the ABPN – modern standard – can occur even if the psychiatrist does not practice or see patients.

5)  physicians who headed psychiatric clinics or hospitals – many prominent examples like Franz Nissl who did research with Alzheimer and Kraepelin and is known for histopathological discovery but he eventually replaced Kraepelin as Professor of Psychiatry and Director of the Psychiatric Clinic at the University of Heidelberg.

6) attending physician in psychiatry.

7) physicians trained by self-identified psychiatrists.

With those expanded criteria – we can look at additional Nobel Laureates in the table below:

Looking at the table of Nobel laureates Only Wagner-Jauregg and Deisseroth practiced clinical psychiatry.  Kandel was trained and board certified as a psychiatrist but worked as a basic science researcher. I would count all three as psychiatrists. 

Of the remaining laureates the following completed medical degrees Camillo Golgi (University of Pavia 1865), Santiago Ramón y Cajal (University of Zaragoza 1873), Otto Loewi (University of Strassburg -1896), Henry Dale (Cambridge University 1909), António Egas (University of Coimbra 1899), and Ulf von Euler – (Karolinska Institute 1930). 

Two of the laureates were trained as PhD scientists Julius Axelrod (George Washington University - 1955 and Paul Greengard (Johns Hopkins University -1953).  The remaining three laureates were trained as physicians and scientists - John Eccles (MB, BS, MD -University of Melbourne) (Oxford - DPhil 1929), Bernard Katz (MD University of Leipzig – 1934) (PhD University College London – 1938), Arvid Carlsson – (MD, PhD University of Lund – 1951).  The interesting observation in this case is that most of the Nobel awards were to scientists with medical training or combined MD/PhD training.  There is some selection bias since the category is Medicine or Physiology.  

Even though neuroscience is considered a relatively new discipline it has historically had a close relationship to psychiatry for over 100 years.  Psychiatry has developed out of the close relationship with neurology and neuroscience and that seems to be lost by many modern-day critics.  That seems to be semantics more than anything else.  Just because you could not get a BS in Neuroscience in Cajal’s era did not mean neuroscience did not exist.   

In addition to Freud there were several additional neuropsychiatrists or possibly psychiatry adjacent researchers who were nominated but never received the Noble.  Ugo Cerletti (1877–1963) — an Italian neuropsychiatrist had correspondence with the Nobel committee and actively wanted the prize, but controversy about the method as well as conflict with his student Lucio Bini who subsequently patented his own machine may have been a factor in him not getting it.  Others include Joseph Babinski, Vladimir Bekhterev, Henry Head, Eduard Hitzig, and Hans Berger.

One of the fascinating aspects in training and reading about psychiatry is the tremendous diversity in training that occurred.  I previously asked the question whether the field though standardization has become less intellectually stimulating than it was in the past.  I used von Economo’s career as an example.  With standardization you can no longer go through a lab, a neurology clinic, or a psychiatry clinic in 4-year blocks and come out studying and researching whatever you want.  It is rare these days to see an MD doing basic science research, but fairly common to see them doing clinical research.  The neuropsychiatrists of the early 20th century are not the neuropsychiatrists of the early 21st century.  Before the board certification rule in the US in 1934, all psychiatrists were considered neuropsychiatrists.  Today they come in three forms – double board certified in psychiatry and neurology, psychiatrists with a neuropsychiatry fellowship or neurologists with a behavioral neurology fellowship, or self-proclaimed.  None of the psychiatrists doing this work are very visible. Most of the patients they treat are not seen in routine outpatient practice. They are more likely to be seen in acute care settings and specialty clinics.

The reason why the Nobel is so important in psychiatry is not because of the scorecard.  Having people of that caliber in the field, especially when they take an active role in teaching, mentoring and research brings the field up to a higher level.  I think it worked that way in the early 20th century when Warner-Jauregg made a landmark finding in biological psychiatry.  It worked that way when Kandel made similar discoveries in plasticity and memory in the 1970s (8).  I hope it works that way now with the award to Deisseroth.   I hope his work is being studied in psychiatry resident seminars across the country.  

Not that I expect it will stimulate any more MD, PhDs – but I hope it stimulates people to think about what a psychiatrist should know and how it improved our knowledge of the field.  I hope it encourages all of us to expand beyond the roles that have been defined for us by businesses, administrators, or people who otherwise attempt to intellectually restrict the field.

Supplementary 2:  Wagner-Jauregg’s Treatment Malaria Fever Therapy protocol for GPI:

1:  Inoculation of the patient with live Plasmodium vivax (benign tertian) malaria.  This was usually done by intravenous infusion of 4-8 ml of blood from infected patients.  P. vivax was chosen because it was considered a more benign form of the disease. 

2:  Incubation:  It generally took one week before the first episode of febrile illness.

3:  Febrile course: Since the fever was considered the therapeutic component patients were required to cycle through several episodes of fever.  The literature describes this as 5-6 in a series of Viennese patients but as high as 8-12 elsewhere.  The fevers generally occurred in a tertian rhythm meaning thirds as in every third day but the measured intervals were about 31 to 41 hours.  Wagner-Jauregg also used a combined approach adding arsenical anti-syphilitic treatment (Salvarsan/neoarsphenamine).

4:  Termination: with quinine or combination therapy using other antimalarials.

There were some variations in this protocol.  In some cases, mosquitoes (Anopheles spp) were used for the inoculation.  This was problematic because it required keeping a supply of malaria carrying mosquitoes alive.  The blood inoculation required an infected person but that could also be the result of passing the infection through the inoculation route. Blood inoculation bypasses the liver stage of infection and does not result in relapses.  It predictably led to a first episode of fever in a week.  Mosquito bite infections also tended to be more severe and had a more marked inflammatory response even when parasite densities were comparable.
