Pinning a nutrient decreases the number of taps required to access charts for that nutrient and see foods that have contributed to your intake on any given day. To pin a nutrient:
Scroll down to the Nutrient Explorer on your Dashboard and tap Explore All.
Tap on the Settings icon in the top right corner of the Nutrient Explorer screen.
You will be taken to a page where you can configure nutrients. Go to the Pinned to Dashboard section, and tap the Edit button.
Once you are in the Edit Mode, you will see a Plus button and it will be automatically selected. As long as this button is selected, you can tap the Pin button next to any nutrient from the list and add it to Pinned Nutrients. You can also replace any nutrient in the Pinned Nutrients list by tapping on it and then choosing a different nutrient from the list. Finally, you can remove any Pinned Nutrient by using the red Subtract button.
Once you are done, you can tap the Checkmark icon in the top right corner to save your changes. You can also tap the Done button to exit the edit mode and make other changes to your nutrient configuration, as long as you tap the Checkmark icon prior to exiting the page.
Your Pinned Nutrients will appear on the Dashboard under the Nutrient Explorer section.
