Beer is good and for non joke reasons. It is a source of calories and potable water and it can cheer up your mood.

Buy lots of seltzer water soda cans. I can't find pure water in cans except online these days. Also Jello is a good survival food. You can mix with water and drink it that way.

Beer is a diuretic though. If water is short, it is a very bad idea. The net gain in calories and carbs will do you no good if you are dying of dehydration.

Also, beer serves as a diuretic and helps flush your system; lowering your body burden of radionuclides.
