Are funds from health insurance for groceries taxable income?

As confirmed by Shall I report Member Rewards incentive payments from my health insurance for choosing a certain med..., I realize that "Medical Rewards" incentive payments from health insurance [for things like learning about the "Medical Rewards" program, getting a (paid-for-by-insurance) annual physical exam, etc.] *are* taxable as "Other Income".

 

However, I imagine that funds made available (by debit card, 1 time) by the insurance company to help pay for groceries, utilities, and transportation are *not* taxable as income.

Is that correct?
