How can I delete all the health data from an iPhone?

How can I delete all the health data from an iPhone?

I have a 16 GB iPhone. Settings>General>iPhone Storage says that Health is taking up 458 MB of space. I don't use any Health functionality. I would like to delete this information and free up the space.

I cannot delete the Health app.

I have gone into Settings>Health>Data Access & Devices and gone through all the apps and devices listed and have deleted all of those data sources. That helped a little bit, but I am still losing over 450 MB of space.

Please, someone tell me this is possible, that I can delete this health data without resetting and restoring my phone.

Thanks in advance.
