It's an opinion put forth by alternative/holistic practitioners but isn't backed by science. They make the analogy to the atrophy that can occur in the adrenal, and other endocrine glands with prolonged hormone replacement treatment.

The pancreas is different however. The raw foods we have eaten throughout evolution are teeming with plant enzymes and the pancreas, and other sites of enzyme production in our digestive systems are well adapted to up and down regulate enzyme production in the presence of the different foods we encounter.

So, I haven't seen any credible proof of this claim, and it doesn't make sense to me. But you should always do your own fact checking and go with what you find most credible.

Not the case with plant based.
