I think the food system could be enhanced in some of the above mentiones days, but I also thonk there are more important things to fix.
Maybe certain food should be sigested faster than others, or faster in some combinations - even better, after eating sweets you refuse to eat an onion, or both comes out again, for example. Some food would weight you down as it's harder to digest than others, just for a minute or two after eating - full tummy doesn't like to fight. On the long call... given we have weather sometime, you could add a vitamine-system, that raises your protection against disease by eating carrots and stuff, so you don't get a cold that easy while walking through heavy rain. There are many possibilities...
