Surprisingly tasty... but needs a few things
I took one of these camping. Reasonably tasty (although I added salt, pepper, and cinnamon to most things), surprisingly, and mostly good all around. The instant rice and instant potatoes aren't very good - but then, they're mostly just starch calorie fill. Couple of notes:
1) The pouches don't re-seal (although the bucket does). It's dry goods, and theoretically if you're going to *actually* need them, they'll last open the approximately two weeks for the biggest pouch if you follow the plan... but if you plan on actually using this, pick up some large binder clips or something to hold the pouches closed when not in use.
2) The 1,857 average calories per day did not leave me feeling full. I work out regularly, and burn through about 2,500 calories per day to keep my weight stable, so your mileage may vary. That does lead me into...
3) I ran the math: It only averages about 30 grams of protein per day. FDA recommendations say about one thousandth your body weight in protein per day (about 65 grams for an average adult male). You'll want to supplement your protein from somewhere. Fishing, hunting, or perhaps some of Augason Farms other products (they've got preserved meat tins, vegitarian meat substitute dishes, dry eggs, and probably a few other things) is a fairly good idea if you plan on relying on this.
4) The food is almost entirely vegetable matter, but technically not vegetarian. From what I can tell on the ingredient lists, the closest it comes to meat in here is a tiny amount of chicken fat in about half the items. Few people are picky in emergencies, and I personally think animals are, in fact, for eating (also wearing - I like my leather coat), but something to keep in mind.
This does give you enough to get by for a while. The meal plan did not leave me feeling full for long (it's mostly starches, and those digest quickly), though, so in an emergency you're going to be SORELY tempted to burn through your 30 days of supplies in less than that. If you are primarily worried about the power being out for a week due to a storm, this will probably carry you through without issues. If you're planning to use this as a long-term solution, you're going to need to add a few things to prevent nutritional deficiencies, and to help you feel full.
