i’m reading a book right now called “the man who ate everything” and the author describes how many plants have developed nutrition blockers and inhibitors as a defense mechanism against being eaten. therefore, most veggies are not very nutritious unless blanched. i was discussing it with my boyfriend today and we both agreed that this probably holds true in feeding them to rabbits. i doubt very much you have to worry about getting too MUCH calcium.. if anything, i would suspect most of it is not absorbed. also, because of the inhibitors found in greens like spinach, i wonder if that is why we are told they are “toxic” in mass quantities over time? it would make sense to me that consumption of them over time would keep bunnies from absorbing the required nutrients even if they are getting them in their pellets.
of course, i don’t know much about this and i’m just speculating on all of this. perhaps that isn’t the main reason (or a reason at all) we are cautioned against too much of certain greens, but it sure would make sense to me if this were a contributing factor.
interesting, nonetheless!
