Can Foodnoms write nutrition data to Apple Health?

Yes. Foodnoms can save nutrition data from your logged foods to Apple Health.

To turn it on, go to Data & Integrations → Apple Health in Foodnoms settings and enable writing nutrition data. You can also manage Foodnoms' Health permissions in the Settings app under Health → Data Access & Devices → Foodnoms.

Foodnoms writes only the nutrients your food entries include. If an entry has no value for a nutrient, nothing is written to Apple Health for that nutrient.

Note for Mac users: Macs can't access Apple Health directly. Health data is written from your iPhone, so entries logged on your Mac are saved to Apple Health once they sync to your iPhone.
