Subject: RE: Very High ALT level
Message-ID: <1294297.1097014359273.JavaMail.root@thallium.smartgroups.com>
Yes, that ALT level is beyond what is seen with diet problems alone.
Not eating enough or often enough does raise ALT levels.
I have long standing permission to quote this. It is a section from =

Here is the segment:
