That piece was probably written about the original version of Golden Rice developed 18 years ago which was being pushed as the solution to Vitamin A deficiency despite having about one-thirtieth the beta-carotene content of the current variety. When you yourself wrote that "Golden rice has been around for 18 years now, but "activists" have prevented its widespread use. That's 12 million preventable deaths." elsewhere in the discussion, it exactly was this much less effective version of Golden Rice you were claiming that anti-GMO activists killed millions by blocking the use of, not the one used in the linked study. Also, the ease of absorption is annoyingly dependent on the rest of the person's diet (particularly having enough fat and iron in their diet, if I recall correctly). The meals used in that study may well be close to the best case scenario; people with vitamin A deficiency don't generally get that way by having access to well-balanced meals.
