I purchased their program and recipe book and I must say that the information provided is very eye opening and insightful. The website really is a great resource too. I'm sure you could get this info elsewhere but the way they put it together is why I highly recommend it.
Not sure why some here say there's no data backing it up. Their website has a bunch of references and the program has a bibliography. I haven't double checked the sources myself but they seem to all be legitimate medical sources. Overall I'm very glad I found Save our Bones.
