    FOX's Dr. Jennifer Ashton: She's a fox, but no Einstein

    I recently saw Dr. Jennifer Ashton on FOX delivering what I thought was an unjustified minimalization of the importance of nutrition. I wondered if she had some financial incentive to say what she did, or if she were too busy staring in the mirror to learn more before she opened her mouth and misled the viewers on FOX who might assume that she really knows what she is talking about because she is a doctor. Dr. Ashton is exceptionally attractive, and she evidently wants potential patients to know that, because her web site currently features a slide show with various large pictures of her. I wondered, “Is she a doctor? Or a model?” She's a doctor, alright, but I doubt that she graduated at the top of her class. If she did, why didn't she know the facts that I mentioned in my message to her? (see below) I don't understand how any doc who knew that info could give the report that she did.

    I would be thrilled if Dr. Ashton were ethical enough to send a resignation letter to FOX in which she said the following:

    “I am not the smartest doctor in the world, nor am I the most knowledgeable. I am, however, arguably the most attractive female physician on Earth, which is likely why you chose me over other candidates who have better brains but uglier bodies. While I appreciate your confidence in my ability to spellbind viewers, especially men, as a doctor I know that health is too important of a topic to have health presentations on your channel given by anyone except the best and the brightest. I am smart, but not the smartest, so please accept this resignation and, for heaven's sake, please stop pandering to the people who value beauty over brains.”

    I discussed the Attractive Expert Syndrome on one of my web sites, explaining why society is almost invariably harmed when the selection criteria for experts includes their appearance.

    Here is the message I sent to her:

    I saw your report on vitamins this morning on FOX, and I am alarmed by your overall message. Are you aware of the prevalence of genetic mutations producing apoenzymes with decreased coenzyme binding affinity, as evidenced by their increased Michaelis constant (Km)? Are you aware that administering high doses of the vitamin component of the coenzyme can remedy or ameliorate about 50 (and likely far more) human genetic diseases by at least partially restoring enzyme activity? (Incidentally, this therapy is also useful in other cases, including polymorphisms that heighten disease risk, when a mutation affects the coenzyme binding site of the apoenzyme.) Did you know that a substantial percentage of people are affected by polymorphisms? Do you ever take complete dietary histories on patients? I've done this, which has given me remarkable insight into the junk that most people eat. I know that you must be a very busy person (aren't all doctors? :-), so here is a simple way to assess average nutritional intakes without any extra expenditure of time: Just look at what people buy in supermarkets! Many people obtain a substantial percentage of their daily caloric intake from refined sugars and foods that provide little nutritional value.

    I've done enough TV and radio interviews myself to know that the need to give a "Cliffs Notes" version of the facts necessitates that the presentation be brief and therefore often lacking in essential information, so I am doing my best to not be overly harsh in judging your presentation today. However, it seemed to me that you had enough time to give a more balanced presentation than what you did.

    I attended a medical school that stressed nutrition, yet even though I graduated in the top 1% of my class, I still think that I learned little about that subject — which is really just applied biochemistry and physiology. I've since worked hard to remedy that gap in my knowledge, so I likely know far more about this subject than an average physician, who'd probably say, "Michaelis what?" The more I learn, the more I realize that the average American diet does NOT provide optimal amounts of all vitamins and minerals at all times, nor does it provide optimal amounts of various phytochemicals that are conducive to health. I typically spend an hour every morning studying this subject. After years of doing it, I have acquired thousands of articles which bolster my case that average Americans could benefit greatly from improved nutrition in general — not just the few nutrients you singled out. If you disagree, I'd love to debate you. The loser pays $10,000 to the winner's favorite charity. Deal? :-)

    Evidently not. She never responded.

    So, FOX, how about replacing that fox with someone who knows more?

    I lost all respect for Dr. Ashton when she was on the Dr. Oz show and referred to women as being "Just Very Unlucky" who contract an STD. I just thought it was very degrading, and incenative, to these women, who deal with these problems. I would think a doctor on national television, would be more compassionate, and use a more sensitive vocabulary towards people who are already dealing with some very sad life issues. I am dissappointed at DR. Oz, for not editing that segment as well.
    Thank You,

    Oh, a question. This is just an idea I've had, and I wonder if there is experimental evidence to back it up.

    Humans have various regulatory mechanisms, a whole mess of hormones and neural structures, to maintain their body mass more or less constant. I wonder if obesity happens because the extremely high calorie foods common in the American diet, that require very little chewing or time to consume, violates the 'assumptions' under which our regulatory system has evolved.

    We haven't gotten to this part in medical school, but I have noticed that the kidney has a whole raft of dependencies and assumptions. For instance, if you change the input pressures that get past myogenic autoregulation, the kidney fails. The various ion shuffling it does also depends on relationships between the ions that aren't always correct.

    This is why a diet of donuts makes humans fat, while a diet of steak and vegetables doesn't seem to. Meat has about the same caloric density as donuts, but it contains protein and must trip all sorts of receptors in the brain designed to handle this. Certainly, from a personal level, I feel full for many, many hours after eating a big meal with meat in it, but can eat a whole stack of donuts or candy a short time after consuming the last bunch.

    Yes, they do teach this stuff in medical school today. Basic chemical equilibria and binding affinities are briefly mentioned.

    It's hard to see how to use this stuff clinically, though. If the patient doesn't have a genetic disease, then high doses of vitamins won't generally help, right. Also, you have to give them the right vitamin : you can't just give every patient an overdose of a multivitamin.

    Sure, there's genetic tests, but you have to know to order one, and be lucky enough that there is a test for that particular disorder.

    And finally, you have the same problem with many other clinical interventions. If these genetic disorders are rare, then asking a patient about nutrition is almost always a waste of time.
