The main title in the article ("The Toxic Truth") is a tribute to UCSF's famous Dr. Lustig of the lecture "Sugar: The Bitter Truth" [1], which is a fascinating and well worthwhile lecture about the biochemistry of fructose as it relates to obesity. I thought I'd just watch a few minutes of it and ended up sitting through it and learning a whole lot.
He also wrote a book on the topic("Fat Chance: Beating the Odds Against Sugar, Processed Food, Obesity, and Disease")[2].
Lustig has always stuck me as a bit alarmist. Another red flag are his attempts to capitalize on his increase in popularity. That being said, he does seem sincere and not attempting to spread disinformation as such.
