Looks like "Dr." Null has his own credibility problems:
Null says he holds an associate degree in business administration from Mountain State College in West Virginia, a bachelor's degree from Thomas A. Edison State College in New Jersey, and a PhD in human nutrition and public health sciences from The Union Institute in Cincinnati, Ohio. Edison State, a "nontraditional" school with neither campus nor courses, awards accredited bachelor's degrees based on career experience, equivalency exams, and courses taken at other schools.
