Your comment got me interested in actual numbers, so I did some Google searches. I expected to find a small but nonzero number of yearly deaths. The results I found indicated that death by starvation in America is so infrequent that it's not even tracked. Occasional cases do occur, but they are often the result of something other than lack of access to food, such as child neglect or mental illness. Even Feeding America only talks about the effects of hunger and food insecurity, not actual starvations. There are lots of programs, both government and private charities that provide food and assistance to those who need it.
That's not to trivialize the very real problems of malnutrition or hunger, which can have serious consequences. But outright death to lack of access to food does seem to be practically non-existent in the U.S.
