My quote: “take out important parts because it’s cheaper to produce and makes a better texture when reconstituted”
Your version of my quote: “taking out important parts because it is easier to produce”
Two different meanings - if you’re going to quote, please quote correctly.
Here’s one source…“The process of milling breaks down the grain’s protective bran, and exposes its germ to air-borne microorganisms. These start feedingon the germ, and begin turning it rancid. Toprevent rancidity, the milling machinery removes the germ. And for better texture and color, it also removes the bran. What remains is the endosperm. This lifeless part of the grain is then further processed, refined, bleached and treated to become teh nutritionally desolate version of wheat known as white flour. It hasa long shelf life because microbes cannot subsist on it very well, and neither can we.” Beyond Backpacking p.180
Since processed grains have significantly longer shelf lives, the investment from production to sale ends up being much cheaper because less product spoils and you don’t have to spend so much money in transaction costs, like for refrigerated transport, for example. Therefore, “because it’s cheaper” in the long run is true. And with the bran and germ removed, the endosperm has very little nutritional value, so the cheaper version is also not as good for you as the whole grain version.
So if freeze-dried food is “much better than what you can make at home”, I guess it depends on how you eat at home. Simpler and tastier, perhaps. More nutritional? Again, it depends on how you eat at home.
I don’t claim to be an expert, and I’m not against freeze-dried food. I already said I eat it from time to time. But if you can find a source extolling the health benefits of it, I’d be interested learning something new.
I’d also be interested to see if MH has any meals that don’t contain processed or refined flour. Because if they don’t, their products have indeed taken out the important parts of the grain, in which case you’re making a claim you can’t support. And that’s just silly.
