In Season 1, Episode 3 of the television series "True Blood", the following conversation takes place:
Sookie: Marthaville’s gettin’ a Starbucks.
Gran: I cannot for the life of me see why anybody would spend $3 on a cup of coffee with too much milk.
Sookie: Arlene told me, that people are less calcium-deficient than they used to be because of all the fancy coffee they drink nowadays.
Gran: You know, I never thought of that, but it does make sense.
I guess, this claim is part based on the fact that a Grande Latte has 40% of your RDA
Is it true that the change in diet to milky coffee has reduced calcium deficiency in americans?
