Health Data is suddenly using a lot of iCloud Storage on iOS 10 I've noticed that since I've upgraded to iOS 10 public beta, Health Data is using 275mb of my iCloud storage (and it's increasing), which I think is much more than usual.

As far as I can recall, it was less than 10mb on iOS 9. Any ideas on why it's eating up iCloud storage and how to resolve this issue?
I don't really know what else you can do about it, except don't back it up. This really feels like a bug/optimization problem on Apple's side. 
Mine is 655MB and I'm pretty sure it was ~500 just a week or two ago.
