Has anyone tried the paleo diet? Do it help?

Has anyone tried the Paleo diet and does it help? What about Coral Calcium? I have also heard that helps.

We know that cavemen had extraordinarily high levels of degenerative spinal disease, Osteoporosis, and lived a very short life span. Almost all of which is attributed to their diet. We also know that if the supplement industry were regulated, produced forced to show evidence for their claims of efficacy even close to that of our medications (approx 20%), there would be no supplement industry.
