I'm with you guys, never been too impressed with freeze-dried stuff or MRE's, especially when you look at the cost. All the veterans I know make a point of avoiding MRE's when they can, what does that tell you? Then again, I don't go out for 2 weeks with only what I can carry, either.
Wholeheartedly agree with bringing some taters and noodles, even Ramen if you can stomach it (I can't abide the smell of that stuff, let alone the taste). Complex carbs, plus a couple cans or packages of veggies goes a long way to keeping you fed. Grocery stores carry individual "bachelor-size" cans of veggies with a pop-top, those make a lot of sense to me. Jerky and uncut sausage can last for days without refrigeration. I also like the foil pouches of tuna and chicken, there's your meat and fat requirements. For a planned trip, it might be worthwhile to bring a small soft-sided cooler with a chemical icepack in it, for fresh meat and cheese. Remember the captain in "Saving Private Ryan"? He was always nibbling on raisins when he got the chance. I despise raisins, but dried fruit has to be a good way to keep hunger at bay and get some sugar into your blood.
What about the old-school guys who go into the woods with nothing but a chunk of bacon, some lard or butter, and flour,Bisquik, or pancake mix? I know diddly about making johhnycakes or biscuits over a fire, maybe it's time I learn. Not to mention getting serious about edible plant ID and the various methods of trapping fish and game.
Always remember, the more any food product is processed, the less nutritional value it has. I presume this applies to freeze-dried stuff as well, although it may not make a huge difference.
I like Gatorade mix for my water, I can't shake my sweet-tooth even in the boonies

. I sneak a few small cans of low-sodium V8 juice in my pack for vitamins and "comfort". Those protein/meal-replacement drink mixes and bars athletes use pack a lot of nutrition and calories in a small space, but they're on the pricy side. Maybe a couple for last-ditch survival OR if you're too busy to sit down and cook something, would be a good idea. Don't disregard the classics like dry soup mix and boullion cubes. CHEAP, lightweight, warming, and filling. Just don't tell your doctor, those things are LOADED with sodium! Drink an extra glass of water. Also, a small ziplock full of ketchup/mustard/hot sauce/salt/pepper packets from the fast "food" place can really help make stuff go down easier.
This is a cool thread, I don't think you need to buy the latest-greatest-high-tech-survival food to stay fed and even comfortable in the boondocks. Looking forward to other suggestions.
