"Hungry for Change" documentary critique?

[EndlessResearch]

Have any of y'all seen the Hungry for Change documentary. They demonize white sugar, and push juicing low glycemic veggies and eating super foods like chia seeds, chlorella, spirulina. They say how these people beat cancer doing this stuff, and that white sugar is like the cocaine of foods and is causing insulin responses that are associated with weight gain. If anyone has seen this documentary, I would really appreciate a in depth critique of the concepts presented. I watched it on the Amazon Prime instant view. Thanks!
