I would definitely like to see carb counts with restaurant foods and meals. At a restaurant that we go to (not a chain) the server will recommend the mashed cauliflower in place of mashed or baked potato if you ask about low carb choices.The question is, how much butter is in the mashed cauliflower? I have gotten good at ordering a meal off the menu that they always have and I can bolus for the carbs and usually come out with a post meal blood sugar on target plus or minus a few points. Of course there are occasions when nothing goes right and there is no way to explain it. Sh**happens! Biological systems are easy to monitor and difficult to control.
A good no fat salad dressing at home is Balsamic vinegar + lo sodium V8 juice with some added fresh herbs.
Back during the so-called "low carb" fad, a couple restaurants did post the carb counts on their menu items, or at least on a special "low carb" menu selection.
The problem was, if I recall correctly, that they weren't honest, because the food was full of sugar alcohols which they were ignoring and the portion sizes were not teh actual portion sizes that showed up on the plate.
The problem of dishonest carb counts is a huge one, and one I'm seeing more often. A lot of foods now list the total carbs with the fiber already deducted, which is NOT how U.S. labels are supposed to work.
