It's really not a "skewed perception" to say that doctors get little training in nutrition, that's simply a fact. Some schools require none, others a couple dozen hours, others somewhere in between ... it's simply not a big part of their training. And it's very well known that nutrition plays a large part in disease prevention, I don't think that's controversial - diabetes is one very clear example, where dietary habits are clearly linked to the disease. Like I said, this goes all the way back to Hippocrates.
Many of our leading fatal illnesses are impacted by diet - diabetes, as already mentioned, heart disease (doctors give dietary recommendations to patients who have that), strokes (related, obviously, to cardiovascular disease), high blood pressure (which can be related to kidney disease), cancer (the WHO has listed some foods as carcinogens), and others.
So ... this will be a little long. On a personal note, I can attest very directly to this matter of doctors and disease prevention and cure. I had a heart attack about 5 years ago, and had two stents put in, one for an almost fully blocked artery, and another for one that was substantially blocked. This was an effective intervention which may have saved my life. So, yay for "pills and procedures" on that score!
Subsequently, the cardiologist, and my regular physician, recommended a "Mediterranean Diet", and prescribed several medications. However ... after about a month, I began to have recurring chest pains, a daunting experience, as one might imagine. I was prescribed more medication, and told that the goal was to try and manage this incurable, progressive disease.
Fortunately for me, a friend gave me a book by Dr. Dean Ornish on preventing and reversing heart disease.
Reversing! Not possible, according to the cardiologist. Hmm. I started following Ornish's recommendations, having nothing to lose. This mostly involved exercising regularly (as I'd already been doing, walking on a treadmill in cardiac rehab), and eating a very low fat plant based diet. And, lo and behold, the chest pains went away ... I dropped the meds for that ... and it became possible to exercise more vigorously ... my blood pressure dropped, my cholesterol levels went down ... . About a year later, my doctor was looking at my chart, kind of shaking her head and saying, "Boy, your numbers look
really good ..." (They're not used to seeing that with heart patients). I said, "Yeah it's that Dean Ornish veggie thing I've been doing." She said, "Yeah ... most people won't do that." And I felt like saying, "Well, they won't do it if you don't TELL them about it!" (But I refrained.)
This is a direct example of the way in which doctors often get caught up with the pills and procedures in which they're trained, and can be blind to ways in which these diseases can be cured, and prevented in the first place. Cardiovascular disease is an incurable, progressive disease. No, it AIN'T! But they're not trained in this, and there's no money in saying, eat broccoli. That's not conspiracy, that's just medical economics.
As a footnote, at this stage, 5 years down the road, I've progressed to the point that I
regularly run half marathons, and fears of another heart attack are way in the rear view mirror. It's been demonstrated in a number of studies that such recovery (though not always this dramatic) occurs when making the necessary lifestyle changes. Cardiovascular disease is a food borne illness. In so many words. And it's not
just cardiovascular disease.
That's the kind of prevention, and cure, that doctors are generally not taught. It's a real, easily identified thing. I'm grateful for the doctors' skill, and grateful to be alive. But I'm kind of pissed they didn't tell me how to fix things (my new doctor gets it, and is quite good in this area

).
