True for some. My point is that MDs do not know what to tell a patient about diet other than…. Lose weight and exercise. They were not taught nutrition. And terrible nutrition is by far the reason they have patients to begin with. Then the hospital continues to feed said patients the vegetable oil buttery spread poison. Facts.
Basic nutrition is taught throughout public education, including medical school. Your assertion that "MD"s do not know what to tell a patient about diet other than... Lose weight and exercise" is false. Basic nutrition can likely be summed up in 3-5 sentences anyway. Nutrition science is not complicated unless being fine tuned for specific pathology or performance goals.
I have been a provider for 18 years and have extensive training in nutrition. I've counseled patients for over a decade I can tell you, based on first hand experience, that it's mostly a waste of time. Patients don't have a knowledge problem, they have a behavior problem. Most of them know, at least on some very basic level, the lifestyle changes that are needed to improve their health. The vast majority are simply unwilling to do it.
I have a young Registered Dietician in my office. She's dismayed at the fact that her patients, who pay her quite well, simply don't do the most basic things she teaches them. I fear that she will probably quit healthcare as a result of the frustration of dealing with people. She spent years gaining the knowledge and skills of nutrition, but her day to day work is more like babysitting noncompliant adults
Hospital nutrition does tend to be a disaster though, I'll agree with you there.
