but, actually, i need to recalculate that, i think. the number is taken from the back of the carton, and should be relatively standardized. i mean, it's more reliable than the usda numbers on calcium in spinach, or something. but, it's presented in terms of a percentage and if i'm going to base my calculation on the 1300 mg rdi, i should realize that the percentages being presented on the box likely need to be adjusted downwards.
so, i'm getting 48% from the soy. but, 48% of what? and, the answer is not 48% of the 1300 mg rdi like i'm following through with but no doubt 48% of the more standard 1000 mg rdi, which needs to be adjusted to .48*1000/1300 = 36.9% of the 1300 mg rdi. so, that takes me down to a more reasonable 59% right away.
in fact, i should do a proper standardization of the data to make sure there isn't anything else like that lurking in there.
but, what is the evidence for excess calcium being dangerous?
