To be honest, after The Big One, I don't think you have much to fear. Why? Well, looking at, say, katrina, how long was food an issue? A week or 2, until MRE distribution points were up and running? I really doubt cats and dogs would be on the menu for most people. Heck, being on the bay, lots of folks might decide to try fishing.

Most of us here would be able to scrounge enough food (AFTER our stocks ran out), to be comfortable for 2 weeks. 2 weeks that might not even dent the pantry for some folks.

Having said that, being in America, a litte forced starvation would probably be a good thing. That spare tire most of us have has a lot more food that we think. "Eating healthy" in limited food situations has more to do with micronutrients than protein, carbs, and fats. For proof, look at most hospitals: any abdominal surgery patients is usually not eating for up to 5 or so days after surgery. A little sugar water (D5 1/2 NS)running during then and they're fine.

Me, I have a case of MRE's, a 5 lbs bag of rice, 6 boxes of Kraft Mac & cheese, and a few Mainstay ration bars. I figure if I need to, I can make a month of that. I'll be hungry and probably 10# lighter on day 30, but I doubt I'll be fighting off any wierd infections or looking like a concentration camp survivor.

In conclusion, don't sweat a "healthy" diet. Any horribly, junk-food, high-fat, high-sodium, high-carb diet you may have will NOT be that big a deal... unless you have some wicked heart failure, blood pressure, or diabetes. A high salt diet could be dangerous in the first 2, and hyperglycemia for short periods isn't usually life threatening for the last.
