Yucky hospital food

Why on earth can the government not see that having good, delicious, nutritious food is extremely beneficial both physically and mentally? I've never had a serious illness luckily, but even when I've just had a cold or something, I always try to focus on what I'm eating to make sure that I'm giving my body all the nutrients it needs in order to be able to recover. I can only imagine that this is waaaay more important if you are suffering from or recuperating from an illness serious enough to hospitalise you.
