Starving

I don't know how much food people are getting in Gaza. But there is information about hunger and starvation in general that should be kept in mind when reading the reports.  Going on fasts for religious reasons provides pretty good evidence that a healthy adult who is hydrating can go up to about forty days without incurring permanent damage. That is taking in no food at all. With zero food, organ damage starts to set in and death occurs about 2-3 weeks later. Taking in some food, even below what is considered necessary to sustain life, can extend life much farther. Organ damage still occurs, but at a slower pace. During famine, people can be underfed for a year and still be alive, though they may never fully recover even when nutrition is restored. 

It is quite different for children. Zero food can mean organ damage in two weeks and death in three.  It is difficult to get good information on the organ damage and death parts because the organisations that keep the statistics are often focused on "food insecurity," or being "underfed" rather than malnutrition and death. It is a classic motte-and-bailey fallacy of trying to discuss starvation only to have them retreat into "well 1 in 5 children is underfed." Similarly there are questionnaires (and I have administered them) about whether mothers worried whether their children would have enough to eat at least x number of days in the past month. "Oh, so you don't care whether those children are hungry?"
