After looking at several of Dr Day website my personal opinion is that she herself is poison. Sure she mingles good with the bad (so does satan) but she is extremely antisemitic and though there maybe some truths scattered about her hate against everyrhing jewish is a sign she is definetely not used by God as she claims if so she would freely publish her materials online to help others out of Gods love. So diet might work but woe for the spiritual cancee you migh contract. Again she has many truths in her writings but a half truth is also a lie
