That's exactly what my mucker said; he also said that Marcus Rashford's charity clearly failed to do any due diligence upon the provider of the food boxes.
If I were doing this I'd have got a dietician/nutritionist to draw up a template for what should be in each box. Get someone from the distributive trade to cost it up and that'd give you something to build on. I'd imagine the stores would bite your hand off for the good publicity.
As it stands this looks like some of the campaigns during the war for scrap metal, UK, and furs for the Russian front, Germany.
Both cases gave lots of feel good for the public and left the governments with shed loads of junk. Dumped at sea in the UK's case and flown out of the cities and burned in Germany's. Benefits to the troops at the front? Zero.
Mr Rashford feels good about himself and any help for the children is pure serendipity.
