The Food Tracker is a tool used to keep track of the foods you eat. If you can't find the food you're looking for you can always plug it in yourself like I did with a brand of tuna that wasn't listed so I got the information from the can of tuna I ate and plugged it in and now it's a part of my food tracker list. You can also use the copy button on the food tracker to copy the same meal to another day.
The Food Tracker is NOT smart app or anything like that, it just does what you put into it. I always say if the food I'm eating isn't listed or I can't find the nutritional info on it online somewhere or on the packeage of the food I'm eating, I ain't eating it, LOL!!!!!
