I keep a "written" journal of the foods I plan to eat. Usually the written journal has two parts, what I plan to eat (menu set up in advance for when I grocery shop) and what I actually eat. Then, I load them into fitday.com daily to every few days. Also, while Im planning meals, I can use "what if" scenarios before I even buy the food. I've wasted a lot of food before doing this. Now I can narrow down the portions and everything. It's such a great tool!!!
