so, we know that carrot cells will react to fungi by producing chitinase, when provoked.
but, that doesn't answer questions regarding how useful that reaction is in aiding human digestion - a little, a lot or not at all. for example, does it matter if the carrot is removed from the ground or not? is there chitinase in the carrot "food matrix", or does it need to be produced by a living plant?
in radishes, they actually found a specific genetic marker for it, but it still doesn't answer any of the questions i have about digestion - i want to see a dedicated, specific study before i jump to that conclusion.
as of now, mushrooms are still useless, and nutritional yeast is only useful because it's fortified.
sorry.
