I don't see where you have posted those previous questions, but we do respond. As for tracking, you can go to your nutrition tracker, you can type a food item in the search box that says "what did you eat?" Once you do that, click on the search button and you should then see a list of items that you can click on and then add it to your tracker. When added to your tracker, the calories and other nutrition info will show on your nutrition tracker.
