Just catching up with this thread, sorry to go back to food weight and number of trucks but I think this paragraph from the linked BBC news item on a previous page is relevant.
Cogat, the Israeli body that coordinates humanitarian aid to Gaza, said on 1 April that an average of 140 trucks a day carrying food entered Gaza. It said this was more than the 70 trucks carrying food specifically that entered Gaza before the war (500 trucks in total entered Gaza each day before the war).
Note it says "Cogat...said", the article is clear that Cogat coordinate humanitarian aid, they would have nothing to do with food "imported into Gaza" for sale in shops which would be in addition to the food aid trucks. Food insecurity for people in Gaza, before the war, was sufficient to warrant 70 trucks a day of food aid and now that little to no food for sale can be taken into Gaza the number of *aid trucks" have doubled to feed the entire population. It's clearly insufficient.
I would also like to note that food weight is not the best indicator of whether sufficient food is being allowed in. Water has zero calories per 100g, celery has 14 calories per hundred grams and cheese has 430 calories per hundred grams. All those items weight the same but have substantially different nutritional values. I would like to know how much water and how many calories are making it into Gaza.
I think we all know it's nowhere near enough even if there were no problems with distribution.
