I read that and have come to the conclusion that this person was simply wrong. I hoping that I was wrong and it was possible because nuts would be a great food to store.
We did plant some almond trees in our orchard and hope to be harvesting fresh almonds in a few years!
My experience with trying to vacuum seal stuff in jars that is oily, is that the vacuum pulls the oils out. Of course my sealer wasn’t too sophisticated, I guess it couldn’t tell when to stop. Something I do with some things is freeze, then vacuum. But not a high vacuum. I saw some comment about if you froze and then high vacuum, would the ice crystals vaporize giving you a real freeze dried.
I know nothing about this but happened upon this:

“The only thing you can not oven can is dry foods that have oils in them. I oven can almonds, and pecans, but walnuts do not can good at all. They will go bad, but it is due to the amount of oil, so they get tossed in the freezer.”
