Ditto!
And as Glockaroo points out, nutritionally it's pretty bad on you. I mean, Mayo is pretty calorically dense. Of course, no point being prepared when you have that fatal heart attack on your third bottle of a Mayo-only diet (shuddering - I hate mayo).

I get generic, store brand, creamy peanut butter. With preservatives it lasts for, well ... I've never sen it deteriorate. It may separate a bit, and the flavor gets bland in the long run, but I've had peanut butter that was stored for ten years in a kitchen cabinet, not refrigerated, and it wasn't bad. Picky eaters might turn up their nose but if you're hungry, in a survival situation, it works.

I suspect that it would still be eatable for years more.

Most of the survival foods, Datrex and MREs, and similar, tend to remain eatable for years after their 'expiration dates'. You lose flavor and, possibly, nutrition but they still swallow and keep the legs pumping.

Excellent research! I always get into trouble on this forum when I'm on vacation and it's raining.
What if I put the PB on hardtack or a cracker? Got carbs and still way cheap.

Drizzled with honey too! mmMMM!

Let's slather Skippy on a hunk of Datrex! <insert Homer Simpson drool sound here>

I would really hope that my food stocks will include a variety of suitable foods, including both peanut butter and a Datrex-like food bar, so that I can eat a reasonable variety...

I love crunchy Skippy. I was really bummed when we couldn't get it for a while here (some recall IIRC). It doesn't make me thirsty, but I seem to have a real tolerance to not feeling thirsty under just about any circumstance (probably a dangerous thing).

Skippy and sockeye salmon sandwiches <more Homer drooling>

Having been on a low carb diet for the better part of 2 years now, I question the conventional wisdom of needing carbs for energy. Fat is a much more dense source of energy.

I have never experienced an issue with running out of energy, and it is just not a problem for the majority of the millions of people who are low carbing it.

Me, I would go for the PB. I don't think PB causes thirst though. It may cause some dry mouth because of the nature of the food which might lead to a desire to drink.

I suspect the reason the peanut oil is replaced with some other oil is that peanut oil is valuable.

It is true that carbohydrates contain a small amount of water (that is what the hydrate part means) but the amount is small enough that it probably does not make all that much difference.

I think peanut butter is a good survival food but I have to agree with Doug_Ritter that it is thirst provoking. It is also high in salt. So don't depend on it if it is likely that water is going to be critically short.

Florida, with a high groundwater, heavy rains, and lots of surface water is not likely to be in short supply. The water will need treatment but there is seldom any shortage.

If you are buying a ration for storage in a life raft pack on a airplane or boat that operated primarily over salt water, a situation where there is a good chance you are going to start short of fresh water and only have it get dearer as time wears on, you are going to want to go with the Datrex.

If you are more far more likely to be in a situation where drinking water will be plentiful you might save a bit of money by including more peanut butter and less Datrex.

It seems wise to always include some amount of ration that doesn't induce thirst or demand water to eat.
