Tracking rice - 1cup BEFORE/AFTER cooking?

It won’t be exact but in the long run it won’t affect much your body won’t care

I prefer dry when using bulk rice. Water content is a big variable. Whatever way you choose, be sure you're picking the corresponding database measure (i.e., using "1 cup cooked" for "1 cup dry" etc.). Be sure your portions are proportionate, most people guess incorrectly - that's where measuring portions of cooked comes in handy. Now, if you're adding things to it (oil, veg, meat, etc.), then of course be sure to capture them too. For boxed items and preparations, use the nutrition label to guide what you do.
