By "dietitions" you mean American dieticians. Here in Israel the dieticians recommend a diet pretty low in carbs. Not "low-carb" by any means but not the USDA recommendations.
In fact I got a diet from a dietition and decided that I could do without the 3 or 4 portions of "carbs" and go Atkins. (who can eat 1/2 cup of pasta or rice)
