When I look for information concerning my family's health, I want unbiased information. The following, by Tim Junk, gave me cause to wonder (http://mlmresourcesmalaysia.wordpress.com/2007/04/25/read-the-controversal-report-on-mlm-company-usana/): "Macwilliam clearly has something to gain financially from promoting Usana. He was also a usana board director until 2003. He is currently going on tour - promoting his book at Usana functions. Last I counted he spoke at 25 big Usana celebrations & gatherings in a 3 month period! His book is being sold at bulk discount - cheaper if you buy 500 copies or more. Who would buy such a volume - unless you design it to be a sales tool for a network marketing company? The "average of opinions" of health writers is not scientific! Ray Strand is one of the "independent" authors who gave opinion. However, his wife is a high-ranking Usana distributor (her picture came out in front cover of a Usana magazine, Ray next to her). The report is published in the languages for the countries Usana operate in - for example which scientist will produce a specific report for New Zealand/Australia, Mexican (in Spanish). The back of the 3rd edition, had testimonials/comments by readers - who ALL happen to be high-ranking Usana distributors!! Not 1 or 2 ... 6 comments from 6 high ranking distributors!! Check frauddiscovery.net. They even list the medical doctor's DISTRIBUTOR NUMBER, Usana rank & income - not independent medical doctors ... but people with financial incentive to promote Usana!"
