Is this sub from subway healthy?

subway is among the healthiest fast food, but being fast food, it is best avoided altogether. My suggestion is to take out the sauce. As a general rule of thumb, never use any sauce. It is soooo unhealthy, and is made in a really disgusting way. Did you know, that the owner of a ketchup company never EVER eats it? Why? because it is very detrimental to health
