Food Content on web site

I'm not sure where to post this so I'm posted here.  Please forgive in the wrong place.  I'm not sure where to find out about editing or having the nutrition information updated on an existing item in the database.  For instance Miller Lite has not alcohol content listed but it it has ~4%.  Do I just add a new Miller Lite and combine the contents or is there a way to edit items that already exist?

Thanks,

N
