Mandatory Health Insurance, How Did This Come First Before Mandatory Food and Shelter?

Viewing a tweet on twitter about food and shelter for all, it hits me, the big problem I have with Mandatory Health Care or Obamacare.
Doing much work with the homeless and the hungry, I realize that without food and shelter there can be no health.
So are we not putting the cart before the horse making it mandatory for each of our citizens to protect ourselves with medical insurance but not making it mandatory to feed ourselves, and not making it mandatory to provide ourselves with shelter.
Seems a little silly when we put it this way doesn't it.
The government says if you can't pay for insurance we will provide it.
Why is the government not saying if you can't pay for food we will provide it?
Why is the government not saying if you can't pay for shelter we will provide it?
If the government truly wants us to be healthy, to go so far as to mandate that all citizens must have health insurance, why are they not stepping in with the ultimate health insurance, which would be food and shelter for all?
