>I think that dairy products contribute to osteoporosis this way, also. This is in layman's terms, but the source is Loren Cordain. The interview transcript is tucked away somewhere in my Word files but I'm feeling lazy. Many dairy foods produce a high acid balance in the body. The first order of business is to even things out. The first line of defense is magnesium, then calcium. Consistent high acid balance drains calcium. He gave an example. By the way, the only way to get rid of the acid is through urine. A 2-litre Coke produces x amount of acid. To get rid of it would take *50 gallons* of urine. This gives you an idea of why osteoporosis is the problem it is. The funny part is that two of the top three acid-producing foods (I forget the third) are hard cheeses and bread. So when the Carol Brady's of this world give Marcia, Jan and Cindy grilled cheddar samwhiches in an effort to build thier bones, they're doing just the opposite. Amazing! Dori Zook Denver, CO
