Red meat, butter and other high fat foods. Part of hcl in stomach - critical for protection from bacteria/killing outside things; break down protein. Ca bank for the other 1% of ca -> for rest of body. Ca and other minerals stick to it. Estrogen - important in retaining ca in bones of women. Balance - body will not let that 1% go out of balance!!
