I agree that doctors don't seem to know as much as they should in terms of nutrition. The argument that "it's the nutritionist that does that" is just a cop-out which only demonstrates that we are taken care of by medical systems which operate in silos: food is the nutritionist, diagnosis is the doctor, pills are the pharmacist.

But a huge part of this, and I'll dare say the greatest part of this equation, rests squarely on the shoulders of parents and educators. Expose your kids to fruits, not fruit roll-ups; peppermint tea instead of Pepsi. Healthy habits start long before you get to the doctor's office, they need to start at home, and carry-on in schools.
