At any time you can see all of the nutrients we track by tapping the "See All Nutrients" button on the "Home" screen of the iPad app.
Beginning with version 1.4 of the MyFitnessPal iPad app, you can customize the nutrients shown in the Food Diary, by changing these options on our website at www.myfitnesspal.com.
Your customized nutrient columns will update the next time the app syncs with the internet.
