You can add the groceries as part of the expense of a caregiver for medical expense purposes just like you can add dog food for a service dog. I divide the total amount of groceries and divide that amount by the number of people in the house. That portion is part of a live-in caregiver expense. But I did not see an increase in my deduction when I added it. I thought it would go up some. It is a lot to add so I wasn't going to do it if it didn't make much difference at all.
