People in general need food to live

People in general need food to live, and to be healthy; the food might be enough to preserve life but not health. A person without any food at all is more 'in need' than someone who does not have food which is adequately nutritious, but it makes perfectly good sense to talk about
both people as being 'in need' - which means that both people have a claim, even if one
claim is stronger than the other.
