I think you would be fine for a long time if you drank old-style beer. Unfiltered, low alcohol content, some remaining sugar/starch and with lots of yeast, maybe some impurities that probably contain amino acids, vitamin b12 and other important stuff.
Yes, potato chips are completely fine in that situation. I don’t know why people say they have too much salt. Sure, they have a lot, but when you have a cold, you’re supposed to drink a lot of water, so that balances out. You can lose a lot of salt due to sweating (especially if you have a fever) and peeing. And salt is a very important electrolyte. And the fat and starch gives you calories.
