I agree that this is a big problem. However, there aren't just 2 alternatives: your doctor's pseudo science or somebody else. Another alternative is to not listen to any advice at all and just eat what you want. America might actually be much healthier today if the government (including through doctors) never started pushing their nutritional advice on us.

I do agree that taking responsibility for your own health is a difficult, time consuming task that may be highly wasted if one can't distinguish between valid and invalid information. I wish I could figure out a way to help people with this process. If I show someone scientifically dense information their eyes glaze over.
