The b12 is produced by bacteria in the soil and is ON the vegetables, not in them. I don't know about soil depletion specifically but I would imagine that dead soil is exactly that and lacks bacteria. But you have the same problem with meticulously scrubbed, or worse, peeled vegetables.Serious question(s) for everyone participating. I've often heard the idea that we don't get the same vitamins and minerals from fruits and vegetables that people used to get because of soil depletion. The idea is that repeated farming of the same land on the corporate farming model has drained the soil so that now the produce doesn't contain the same nutritional content that it used to. Sounds logical. My question is this: do plants absorb minerals and vitamins from the soil that are not essential for them? If an essential vitamin or mineral is missing, the plant won't grow (literally "essential"). So, for this "soil depletion" theory to withstand scrutiny, plants would need to absorb minerals they don't require for survival. Does that happen? If so, how? The reason this question comes up is that many vegans hold that B-12 was available to earlier generations from plant sources, but that soil depletion has ended that. I've heard similar theories from non-vegans promoting all sorts of supplements. Do plants absorb minerals they don't require, or are we really talking about eating dirt? The soil in my garden is being "farmed" for the first time right now. Do my tomatoes and squash have nutritional qualities not found in store bought produce?
Fun fact: factory farmed cattle has the exact same problem and their feed is supplemented with b12, as well, otherwise their meat wouldn't supply you with b12 either.
"The only organisms to produce vitamin B12 are certain bacteria, and archaea. Bacteria are found on plants that herbivores eat; they are taken into the animals' digestive system, proliferate and form part of their permanent gut flora, producing vitamin B12 internally."
