You are so wrong it's hilarious. That statement you made is an out-and-out lie fabricated by the dairy industry for the sole purpose of making money. The calcium found in cows milk does not break down in the human body at all, which is why the USA has the highest population of milk drinkers and also the highest amount of osteoporosis (brittle bone syndrome) found anywhere in the world. Compare that to somewhere like Japan where they do not drink cows milk and obtain calcium from far better sources.....oh what a surprise! they have the LOWEST amount of osteoporosis in the world. Coincidence? Nope.
Now, you can either accept the truth, or I can provide a 25-page thesis written by one of the worlds leading dieticians that has so many
FACTS about the truth of the matter that you will look very, very foolish. Alternatively, Jokerman could provide you with many of the same facts but give alternative examples.
Either way you are wrong. Have a nice day.
