I agree with the second half of what your saying, but on your first point, you cannot always trust the label of these products. Calci-Sand is marketed as safe and digestible, but there are plenty of horror stories proving that to not be the case if you decide to search. That being said, I really don't think that a mouthful of coconut one in a while is doing to do much harm, though it would probably be best to try and avoid it
