So pre-med students failed physiology or they did not seem to undertsnad it? How they managed to get undergraduate degree then I belive it includes more than just memorizing anatomy.
In my home country, my pre-med students peers also took physics, calculus, phys. and oranic chem. and all of this requires understanding graphs and functions, I believe. We just took physics, calculus,a nd phys. chem.
MD is not a mechanic, since human body is not a mechanism, where each part can be isolated and fixed separately. BTW, if a mechanic can't find a problem, he is not a mechanic at all. I work with diffrent type of equipment and we never failed to find a problem and troubleshoot it.
Human body is not a mechanism, it is a biochemical system that involved hundreds of hormones. Just endocrine system alone consists of many glands, not only pancrease, and these glands works synergetically and define the rest of the functions. Unfortunately, many choose to ignore this fact, and simply fixated on one hormone, insulin.
This system is too complex and poorly understood, and each part (organ) can't be troubleshooted and fixed JUST BY ISOLATION. Unfortunately, this approach is used in western medicine and many problems arise because of it. No singe medication exist that treats one problem without creating a dozen of others but this is the best drs can do so far.
As for cholesterol in heart desease connection, it is not completely missunderstood. Those who have choosen to ignore high CHO, take their own chance. Insulin and Bgs fluctuations are of course, damaging, but again, does not explain heart desease and atherosclerosis progression, high blood pressure, and other causes of heart atack and stroke in individuals with normal blood sugar and insulin, and follow up death from MI and stroke.
Low TRG is just a matter of dietary changes, they fluctuate a lot, and not really damamaging. They can spike after one meal and drop sharply, even if you overdone alcohol night before. High LDL is something that is problematic in terms of lowering, many despite proper diet and exercise, normal BGs, still have high LDL. Add to the picture other risk factors: family history of heart desease, any inflamatory reponse to autoimmune deseases (psoriasis, lupus, etc.) and any systemic inflamation in general - and here you have, perfect reason for LDL to be problematic.
It is the same narrow view that got us in troubles with low fat madness. Before it was all about fat, now it is all about sugar, insulin, and carbs. Let's wait another couple decades, and we may find something esle...
As for drs, I still find it facinating with their knowlege, my brain work very well with graphs, mathematical equations, and everything can be logcially derived and calculated. But I would never be able to perform any surgery, even minor, although I know how to give injections, but i am still facinated with drs who save lives and perform miracles on daily basis. The more I read on human biology and biochemistry, the more I realize how hard it is to practice medicine. IMO, mathematically speaking, human body has too many variables to be desribed by few equations and graphs, as mechanism systems and equipment, and does not fit into laws of physics and themodynamics for the most part of it.
So I would rather be on a safe side, keeping my eye on both: CHO and BGs, until it is all clarified.
Best wishes,
