"One kale sample reported thallium at 1.14 ppm, nickel at 20 ppm, and aluminum at 120 ppm. (As has been widely reported, aluminum is often suspected as a cause of both autism and Alzheimer’s disease.)"
Not sure why you're being downvoted for this comment. That was one of the red flags for me as well.
"Often suspected" is a deliberately misleading and alarmist way to present the current scientific data on the relationship between aluminium and Alzheimer's disease.

It's pretty controversial claim that aluminum is related to Alzheimer's disease http://www.webmd.com/alzheimers/guide/controversial-claims-r...
